The filter coefficients are in 1.31 format and the state variables + * are in 1.63 format. The double precision state variables reduce quantization noise + * in the filter and provide a cleaner output. + * These filters are particularly useful when implementing filters in which the + * singularities are close to the unit circle. This is common for low pass or high + * pass filters with very low cutoff frequencies. + * + * The function operates on blocks of input and output data + * and each call to the function processes blockSize samples through + * the filter. pSrc and pDst points to input and output arrays + * containing blockSize Q31 values. + * + * \par Algorithm + * Each Biquad stage implements a second order filter using the difference equation: + *
    
+ *     y[n] = b0 * x[n] + b1 * x[n-1] + b2 * x[n-2] + a1 * y[n-1] + a2 * y[n-2]

+ *     y[n] = b0 * x[n] + b1 * x[n-1] + b2 * x[n-2] - a1 * y[n-1] - a2 * y[n-2]    
+ * 
+ * In this case the feedback coefficients a1 and a2 must be negated when used with the CMSIS DSP Library. + * + * \par + * Higher order filters are realized as a cascade of second order sections. + * numStages refers to the number of second order stages used. + * For example, an 8th order filter would be realized with numStages=4 second order stages. + * \image html BiquadCascade.gif "8th order filter using a cascade of Biquad stages" + * A 9th order filter would be realized with numStages=5 second order stages with the coefficients for one of the stages configured as a first order filter (b2=0 and a2=0). + * + * \par + * The pState points to state variables array . + * Each Biquad stage has 4 state variables x[n-1], x[n-2], y[n-1], and y[n-2] and each state variable in 1.63 format to improve precision. + * The state variables are arranged in the array as: + *

Also set all of the values in pState to zero. + * + * \par + * Use of the initialization function is optional. + * However, if the initialization function is used, then the instance structure cannot be placed into a const data section. + * To place an instance structure into a const data section, the instance structure must be manually initialized. + * Set the values in the state buffer to zeros before static initialization. + * For example, to statically initialize the filter instance structure use + *
    
+ *     arm_biquad_cas_df1_32x64_ins_q31 S1 = {numStages, pState, pCoeffs, postShift};    
+ * 
+ * where numStages is the number of Biquad stages in the filter; pState is the address of the state buffer; + * pCoeffs is the address of the coefficient buffer; postShift shift to be applied which is described in detail below. + * \par Fixed-Point Behavior + * Care must be taken while using Biquad Cascade 32x64 filter function. + * Following issues must be considered: + * - Scaling of coefficients + * - Filter gain + * - Overflow and saturation + * + * \par + * Filter coefficients are represented as fractional values and + * restricted to lie in the range [-1 +1). + * The processing function has an additional scaling parameter postShift + * which allows the filter coefficients to exceed the range [+1 -1). + * At the output of the filter's accumulator is a shift register which shifts the result by postShift bits. + * \image html BiquadPostshift.gif "Fixed-point Biquad with shift by postShift bits after accumulator" + * This essentially scales the filter coefficients by 2^postShift. + * For example, to realize the coefficients + *

+*    y[n] = b0 * x[n] + d1       
+*    d1 = b1 * x[n] + a1 * y[n] + d2       
+*    d2 = b2 * x[n] + a2 * y[n]       
+* 
+* where d1 and d2 represent the two state values. +* +* \par +* A Biquad filter using a transposed Direct Form II structure is shown below. +* \image html BiquadDF2Transposed.gif "Single transposed Direct Form II Biquad" +* Coefficients b0, b1, and b2 multiply the input signal x[n] and are referred to as the feedforward coefficients. +* Coefficients a1 and a2 multiply the output signal y[n] and are referred to as the feedback coefficients. +* Pay careful attention to the sign of the feedback coefficients. +* Some design tools flip the sign of the feedback coefficients: +*
       
+*    y[n] = b0 * x[n] + d1;       
+*    d1 = b1 * x[n] - a1 * y[n] + d2;       
+*    d2 = b2 * x[n] - a2 * y[n];       
+* 
+* In this case the feedback coefficients a1 and a2 must be negated when used with the CMSIS DSP Library. +* +* \par +* Higher order filters are realized as a cascade of second order sections. +* numStages refers to the number of second order stages used. +* For example, an 8th order filter would be realized with numStages=4 second order stages. +* A 9th order filter would be realized with numStages=5 second order stages with the +* coefficients for one of the stages configured as a first order filter (b2=0 and a2=0). +* +* \par +* pState points to the state variable array. +* Each Biquad stage has 2 state variables d1 and d2. +* The state variables are arranged in the pState array as: +*
       
+*     {d11, d12, d21, d22, ...}       
+* 
+* where d1x refers to the state variables for the first Biquad and +* d2x refers to the state variables for the second Biquad. +* The state array has a total length of 2*numStages values. +* The state variables are updated after each block of data is processed; the coefficients are untouched. +* +* \par +* The CMSIS library contains Biquad filters in both Direct Form I and transposed Direct Form II. +* The advantage of the Direct Form I structure is that it is numerically more robust for fixed-point data types. +* That is why the Direct Form I structure supports Q15 and Q31 data types. +* The transposed Direct Form II structure, on the other hand, requires a wide dynamic range for the state variables d1 and d2. +* Because of this, the CMSIS library only has a floating-point version of the Direct Form II Biquad. +* The advantage of the Direct Form II Biquad is that it requires half the number of state variables, 2 rather than 4, per Biquad stage. +* +* \par Instance Structure +* The coefficients and state variables for a filter are stored together in an instance data structure. +* A separate instance structure must be defined for each filter. +* Coefficient arrays may be shared among several instances while state variable arrays cannot be shared. +* +* \par Init Functions +* There is also an associated initialization function. +* The initialization function performs following operations: +* - Sets the values of the internal structure fields. +* - Zeros out the values in the state buffer. +* To do this manually without calling the init function, assign the follow subfields of the instance structure: +* numStages, pCoeffs, pState.

+*    y[n] = b0 * x[n] + d1       
+*    d1 = b1 * x[n] + a1 * y[n] + d2       
+*    d2 = b2 * x[n] + a2 * y[n]       
+*

+*    y[n] = b0 * x[n] + d1;       
+*    d1 = b1 * x[n] - a1 * y[n] + d2;       
+*    d2 = b2 * x[n] - a2 * y[n];       
+* 
+* In this case the feedback coefficients a1 and a2 must be negated when used with the CMSIS DSP Library. +* +* \par +* Higher order filters are realized as a cascade of second order sections. +* numStages refers to the number of second order stages used. +* For example, an 8th order filter would be realized with numStages=4 second order stages. +* A 9th order filter would be realized with numStages=5 second order stages with the +* coefficients for one of the stages configured as a first order filter (b2=0 and a2=0). +* +* \par +* pState points to the state variable array. +* Each Biquad stage has 2 state variables d1 and d2. +* The state variables are arranged in the pState array as: +*
       
+*     {d11, d12, d21, d22, ...}       
+* 
+* where d1x refers to the state variables for the first Biquad and +* d2x refers to the state variables for the second Biquad. +* The state array has a total length of 2*numStages values. +* The state variables are updated after each block of data is processed; the coefficients are untouched. +* +* \par +* The CMSIS library contains Biquad filters in both Direct Form I and transposed Direct Form II. +* The advantage of the Direct Form I structure is that it is numerically more robust for fixed-point data types. +* That is why the Direct Form I structure supports Q15 and Q31 data types. +* The transposed Direct Form II structure, on the other hand, requires a wide dynamic range for the state variables d1 and d2. +* Because of this, the CMSIS library only has a floating-point version of the Direct Form II Biquad. +* The advantage of the Direct Form II Biquad is that it requires half the number of state variables, 2 rather than 4, per Biquad stage. +* +* \par Instance Structure +* The coefficients and state variables for a filter are stored together in an instance data structure. +* A separate instance structure must be defined for each filter. +* Coefficient arrays may be shared among several instances while state variable arrays cannot be shared. +* +* \par Init Functions +* There is also an associated initialization function. +* The initialization function performs following operations: +* - Sets the values of the internal structure fields. +* - Zeros out the values in the state buffer. +* To do this manually without calling the init function, assign the follow subfields of the instance structure: +* numStages, pCoeffs, pState. Also set all of the values in pState to zero. +* +* \par +* Use of the initialization function is optional. +* However, if the initialization function is used, then the instance structure cannot be placed into a const data section. +* To place an instance structure into a const data section, the instance structure must be manually initialized. +* Set the values in the state buffer to zeros before static initialization. +* For example, to statically initialize the instance structure use +*

+ * The state variables are updated after each block of data is processed, the coefficients are untouched. + * + * \par Instance Structure + * The coefficients and state variables for a filter are stored together in an instance data structure. + * A separate instance structure must be defined for each filter. + * Coefficient arrays may be shared among several instances while state variable array should be allocated separately. + * There are separate instance structure declarations for each of the 3 supported data types. + * + * \par Initialization Functions + * There is also an associated initialization function for each data type. + * The initialization function performs the following operations: + * - Sets the values of the internal structure fields. + * - Zeros out the values in the state buffer. + * - Checks to make sure that the size of the input is a multiple of the decimation factor. + * To do this manually without calling the init function, assign the follow subfields of the instance structure: + * numTaps, pCoeffs, M (decimation factor), pState. Also set all of the values in pState to zero. + * + * \par + * Use of the initialization function is optional. + * However, if the initialization function is used, then the instance structure cannot be placed into a const data section. + * To place an instance structure into a const data section, the instance structure must be manually initialized. + * The code below statically initializes each of the 3 different data type filter instance structures + *

Also set all of the values in pState to zero. + * + * \par + * Use of the initialization function is optional. + * However, if the initialization function is used, then the instance structure cannot be placed into a const data section. + * To place an instance structure into a const data section, the instance structure must be manually initialized. + * Set the values in the state buffer to zeros and then manually initialize the instance structure as follows: + *

+ *     y[n] = b[0] * x[n] + b[1] * x[n-1] + b[2] * x[n-2] + ...+ b[numTaps-1] * x[n-numTaps+1]    
+ * 
+ * + * \par + * The error signal equals the difference between the reference signal d[n] and the filter output: + *
    
+ *     e[n] = d[n] - y[n].    
+ * 
+ * + * \par + * After each sample of the error signal is computed, the filter coefficients b[k] are updated on a sample-by-sample basis: + *
    
+ *     b[k] = b[k] + e[n] * mu * x[n-k],  for k=0, 1, ..., numTaps-1    
+ * 
+ * where mu is the step size and controls the rate of coefficient convergence. + *\par + * In the APIs, pCoeffs points to a coefficient array of size numTaps. + * Coefficients are stored in time reversed order. + * \par + *
    
+ *    {b[numTaps-1], b[numTaps-2], b[N-2], ..., b[1], b[0]}    
+ * 
+ * \par + * pState points to a state array of size numTaps + blockSize - 1. + * Samples in the state buffer are stored in the order: + * \par + *
    
+ *    {x[n-numTaps+1], x[n-numTaps], x[n-numTaps-1], x[n-numTaps-2]....x[0], x[1], ..., x[blockSize-1]}    
+ * 
+ * \par + * Note that the length of the state buffer exceeds the length of the coefficient array by blockSize-1 samples. + * The increased state buffer length allows circular addressing, which is traditionally used in FIR filters, + * to be avoided and yields a significant speed improvement. + * The state variables are updated after each block of data is processed. + * \par Instance Structure + * The coefficients and state variables for a filter are stored together in an instance data structure. + * A separate instance structure must be defined for each filter and + * coefficient and state arrays cannot be shared among instances. + * There are separate instance structure declarations for each of the 3 supported data types. + * + * \par Initialization Functions + * There is also an associated initialization function for each data type. + * The initialization function performs the following operations: + * - Sets the values of the internal structure fields. + * - Zeros out the values in the state buffer. + * To do this manually without calling the init function, assign the follow subfields of the instance structure: + * numTaps, pCoeffs, mu, postShift (not for f32), pState. Also set all of the values in pState to zero. + * + * \par + * Use of the initialization function is optional. + * However, if the initialization function is used, then the instance structure cannot be placed into a const data section. + * To place an instance structure into a const data section, the instance structure must be manually initialized. + * Set the values in the state buffer to zeros before static initialization. + * The code below statically initializes each of the 3 different data type filter instance structures + *

The FFT is defined over complex data but + * in many applications the input is real. Real FFT algorithms take advantage + * of the symmetry properties of the FFT and have a speed advantage over complex + * algorithms of the same length. + * \par + * The Fast RFFT algorith relays on the mixed radix CFFT that save processor usage. + * \par + * The real length N forward FFT of a sequence is computed using the steps shown below. + * \par + * \image html RFFT.gif "Real Fast Fourier Transform" + * \par + * The real sequence is initially treated as if it were complex to perform a CFFT. + * Later, a processing stage reshapes the data to obtain half of the frequency spectrum + * in complex format. Except the first complex number that contains the two real numbers + * X[0] and X[N/2] all the data is complex. In other words, the first complex sample + * contains two real values packed. + * \par + * The input for the inverse RFFT should keep the same format as the output of the + * forward RFFT. A first processing stage pre-process the data to later perform an + * inverse CFFT. + * \par + * \image html RIFFT.gif "Real Inverse Fast Fourier Transform" + * \par + * The algorithms for floating-point, Q15, and Q31 data are slightly different + * and we describe each algorithm in turn. + * \par Floating-point + * The main functions are arm_rfft_fast_f32() + * and arm_rfft_fast_init_f32(). The older functions + * arm_rfft_f32() and arm_rfft_init_f32() have been + * deprecated but are still documented. + * \par + * The FFT of a real N-point sequence has even symmetry in the frequency + * domain. The second half of the data equals the conjugate of the first half + * flipped in frequency: + *
+ *X[0] - real data
+ *X[1] - complex data
+ *X[2] - complex data
+ *... 
+ *X[fftLen/2-1] - complex data
+ *X[fftLen/2] - real data
+ *X[fftLen/2+1] - conjugate of X[fftLen/2-1]
+ *X[fftLen/2+2] - conjugate of X[fftLen/2-2]
+ *... 
+ *X[fftLen-1] - conjugate of X[1]
+ * 
+ * Looking at the data, we see that we can uniquely represent the FFT using only + *
+ *N/2+1 samples:
+ *X[0] - real data
+ *X[1] - complex data
+ *X[2] - complex data
+ *... 
+ *X[fftLen/2-1] - complex data
+ *X[fftLen/2] - real data
+ * 
+ * Looking more closely we see that the first and last samples are real valued. + * They can be packed together and we can thus represent the FFT of an N-point + * real sequence by N/2 complex values: + *
+ *X[0],X[N/2] - packed real data: X[0] + jX[N/2]
+ *X[1] - complex data
+ *X[2] - complex data
+ *... 
+ *X[fftLen/2-1] - complex data
+ * 
+ * The real FFT functions pack the frequency domain data in this fashion. The + * forward transform outputs the data in this form and the inverse transform + * expects input data in this form. The function always performs the needed + * bitreversal so that the input and output data is always in normal order. The + * functions support lengths of [32, 64, 128, ..., 4096] samples. + * \par + * The forward and inverse real FFT functions apply the standard FFT scaling; no + * scaling on the forward transform and 1/fftLen scaling on the inverse + * transform. + * \par Q15 and Q31 + * The real algorithms are defined in a similar manner and utilize N/2 complex + * transforms behind the scenes. + * \par + * The complex transforms used internally include scaling to prevent fixed-point + * overflows. The overall scaling equals 1/(fftLen/2). + * \par + * A separate instance structure must be defined for each transform used but + * twiddle factor and bit reversal tables can be reused. + * \par + * There is also an associated initialization function for each data type. + * The initialization function performs the following operations: + * - Sets the values of the internal structure fields. + * - Initializes twiddle factor table and bit reversal table pointers. + * - Initializes the internal complex FFT data structure. + * \par + * Use of the initialization function is optional. + * However, if the initialization function is used, then the instance structure + * cannot be placed into a const data section. To place an instance structure + * into a const data section, the instance structure should be manually + * initialized as follows: + *
+ *arm_rfft_instance_q31 S = {fftLenReal, fftLenBy2, ifftFlagR, bitReverseFlagR, twidCoefRModifier, pTwiddleAReal, pTwiddleBReal, pCfft};    
+ *arm_rfft_instance_q15 S = {fftLenReal, fftLenBy2, ifftFlagR, bitReverseFlagR, twidCoefRModifier, pTwiddleAReal, pTwiddleBReal, pCfft};    
+ * 
+ * where fftLenReal is the length of the real transform; + * fftLenBy2 length of the internal complex transform. + * ifftFlagR Selects forward (=0) or inverse (=1) transform. + * bitReverseFlagR Selects bit reversed output (=0) or normal order + * output (=1). + * twidCoefRModifier stride modifier for the twiddle factor table. + * The value is based on the FFT length; + * pTwiddleARealpoints to the A array of twiddle coefficients; + * pTwiddleBRealpoints to the B array of twiddle coefficients; + * pCfft points to the CFFT Instance structure. The CFFT structure + * must also be initialized.

For example, + * the type + * definition for the floating-point matrix structure is shown + * below: + *
+ *     typedef struct
+ *     {
+ *       uint16_t numRows;     // number of rows of the matrix.
+ *       uint16_t numCols;     // number of columns of the matrix.
+ *       float32_t *pData;     // points to the data of the matrix.
+ *     } arm_matrix_instance_f32;
+ * 
+ * There are similar definitions for Q15 and Q31 data types. + * + * The structure specifies the size of the matrix and then points to + * an array of data. The array is of size numRows X numCols + * and the values are arranged in row order. That is, the + * matrix element (i, j) is stored at: + *
+ *     pData[i*numCols + j]
+ * 
+ * + * \par Init Functions + * There is an associated initialization function for each type of matrix + * data structure. + * The initialization function sets the values of the internal structure fields. + * Refer to the function arm_mat_init_f32(), arm_mat_init_q31() + * and arm_mat_init_q15() for floating-point, Q31 and Q15 types, respectively. + * + * \par + * Use of the initialization function is optional. However, if initialization function is used + * then the instance structure cannot be placed into a const data section. + * To place the instance structure in a const data + * section, manually initialize the data structure. For example: + *
+ * arm_matrix_instance_f32 S = {nRows, nColumns, pData};
+ * arm_matrix_instance_q31 S = {nRows, nColumns, pData};
+ * arm_matrix_instance_q15 S = {nRows, nColumns, pData};
+ * 
+ * where nRows specifies the number of rows, nColumns + * specifies the number of columns, and pData points to the + * data array. + * + * \par Size Checking + * By default all of the matrix functions perform size checking on the input and + * output matrices. For example, the matrix addition function verifies that the + * two input matrices and the output matrix all have the same number of rows and + * columns. If the size check fails the functions return: + *
+ *     ARM_MATH_SIZE_MISMATCH
+ * 
+ * Otherwise the functions return + *
+ *     ARM_MATH_SUCCESS
+ * 
+ * There is some overhead associated with this matrix size checking. + * The matrix size checking is enabled via the \#define + *
+ *     ARM_MATH_MATRIX_CHECK
+ * 
+ * within the library project settings. By default this macro is defined + * and size checking is enabled. By changing the project settings and + * undefining this macro size checking is eliminated and the functions + * run a bit faster. With size checking disabled the functions always + * return ARM_MATH_SUCCESS. + */ + +/** + * @defgroup groupTransforms Transform Functions + */ + +/** + * @defgroup groupController Controller Functions + */ + +/** + * @defgroup groupStats Statistics Functions + */ +/** + * @defgroup groupSupport Support Functions + */ + +/** + * @defgroup groupInterpolation Interpolation Functions + * These functions perform 1- and 2-dimensional interpolation of data. + * Linear interpolation is used for 1-dimensional data and + * bilinear interpolation is used for 2-dimensional data. + */ + +/** + * @defgroup groupExamples Examples + */ +#ifndef _ARM_MATH_H +#define _ARM_MATH_H + +/* ignore some GCC warnings */ +#if defined ( __GNUC__ ) +#pragma GCC diagnostic push +#pragma GCC diagnostic ignored "-Wsign-conversion" +#pragma GCC diagnostic ignored "-Wconversion" +#pragma GCC diagnostic ignored "-Wunused-parameter" +#endif + +#define __CMSIS_GENERIC /* disable NVIC and Systick functions */ + +#if defined(ARM_MATH_CM7) + #include "core_cm7.h" +#elif defined (ARM_MATH_CM4) + #include "core_cm4.h" +#elif defined (ARM_MATH_CM3) + #include "core_cm3.h" +#elif defined (ARM_MATH_CM0) + #include "core_cm0.h" + #define ARM_MATH_CM0_FAMILY +#elif defined (ARM_MATH_CM0PLUS) + #include "core_cm0plus.h" + #define ARM_MATH_CM0_FAMILY +#else + #error "Define according the used Cortex core ARM_MATH_CM7, ARM_MATH_CM4, ARM_MATH_CM3, ARM_MATH_CM0PLUS or ARM_MATH_CM0" +#endif + +#undef __CMSIS_GENERIC /* enable NVIC and Systick functions */ +#include "string.h" +#include "math.h" +#ifdef __cplusplus +extern "C" +{ +#endif + + + /** + * @brief Macros required for reciprocal calculation in Normalized LMS + */ + +#define DELTA_Q31 (0x100) +#define DELTA_Q15 0x5 +#define INDEX_MASK 0x0000003F +#ifndef PI +#define PI 3.14159265358979f +#endif + + /** + * @brief Macros required for SINE and COSINE Fast math approximations + */ + +#define FAST_MATH_TABLE_SIZE 512 +#define FAST_MATH_Q31_SHIFT (32 - 10) +#define FAST_MATH_Q15_SHIFT (16 - 10) +#define CONTROLLER_Q31_SHIFT (32 - 9) +#define TABLE_SIZE 256 +#define TABLE_SPACING_Q31 0x400000 +#define TABLE_SPACING_Q15 0x80 + + /** + * @brief Macros required for SINE and COSINE Controller functions + */ + /* 1.31(q31) Fixed value of 2/360 */ + /* -1 to +1 is divided into 360 values so total spacing is (2/360) */ +#define INPUT_SPACING 0xB60B61 + + /** + * @brief Macro for Unaligned Support + */ +#ifndef UNALIGNED_SUPPORT_DISABLE + #define ALIGN4 +#else + #if defined (__GNUC__) + #define ALIGN4 __attribute__((aligned(4))) + #else + #define ALIGN4 __align(4) + #endif +#endif /* #ifndef UNALIGNED_SUPPORT_DISABLE */ + + /** + * @brief Error status returned by some functions in the library. + */ + + typedef enum + { + ARM_MATH_SUCCESS = 0, /**< No error */ + ARM_MATH_ARGUMENT_ERROR = -1, /**< One or more arguments are incorrect */ + ARM_MATH_LENGTH_ERROR = -2, /**< Length of data buffer is incorrect */ + ARM_MATH_SIZE_MISMATCH = -3, /**< Size of matrices is not compatible with the operation. */ + ARM_MATH_NANINF = -4, /**< Not-a-number (NaN) or infinity is generated */ + ARM_MATH_SINGULAR = -5, /**< Generated by matrix inversion if the input matrix is singular and cannot be inverted. */ + ARM_MATH_TEST_FAILURE = -6 /**< Test Failed */ + } arm_status;

HAL_ADC_Init()/ @ref HAL_ADC_DeInit() only when + these callbacks are null (not registered beforehand). + [..] + + If MspInit or MspDeInit are not null, the @ref HAL_ADC_Init()/ @ref HAL_ADC_DeInit()

done MspInit/MspDeInit functions that can be registered/unregistered + in @ref HAL_ADC_STATE_READY or @ref HAL_ADC_STATE_RESET state, + thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit. + [..] + + Then, the user first registers the MspInit/MspDeInit user callbacks + using @ref HAL_ADC_RegisterCallback() before calling @ref HAL_ADC_DeInit() + or @ref HAL_ADC_Init() function. + [..] + + When the compilation flag USE_HAL_ADC_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registration feature is not available and all callbacks + are

not + (+) @ref __HAL_I2C_CLEAR_FLAG: Clear the specified I2C pending flag + (+) @ref __HAL_I2C_ENABLE_IT: Enable the specified I2C interrupt + (+) @ref __HAL_I2C_DISABLE_IT: Disable the specified I2C interrupt + + *** Callback registration *** + ============================================= + [..] + The compilation flag USE_HAL_I2C_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + Use Functions @ref HAL_I2C_RegisterCallback() or @ref HAL_I2C_RegisterAddrCallback() + to register an interrupt callback. + [..] + Function @ref HAL_I2C_RegisterCallback() allows to register following callbacks: + (+) MasterTxCpltCallback : callback for Master transmission end of transfer. + (+) MasterRxCpltCallback : callback for Master reception end of transfer. + (+) SlaveTxCpltCallback : callback for Slave transmission end of transfer. + (+) SlaveRxCpltCallback : callback for Slave reception end of transfer. + (+) ListenCpltCallback : callback for end of listen mode. + (+) MemTxCpltCallback : callback for Memory transmission end of transfer. + (+) MemRxCpltCallback : callback for Memory reception end of transfer. + (+) ErrorCallback : callback for error detection. + (+) AbortCpltCallback : callback for abort completion process. + (+) MspInitCallback : callback for Msp Init. + (+) MspDeInitCallback : callback for Msp DeInit. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + [..] + For specific callback AddrCallback use dedicated register callbacks : @ref HAL_I2C_RegisterAddrCallback(). + [..] + Use function @ref HAL_I2C_UnRegisterCallback to reset a callback to the default + weak function. + @ref HAL_I2C_UnRegisterCallback takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) MasterTxCpltCallback : callback for Master transmission end of transfer. + (+) MasterRxCpltCallback : callback for Master reception end of transfer. + (+) SlaveTxCpltCallback : callback for Slave transmission end of transfer. + (+) SlaveRxCpltCallback : callback for Slave reception end of transfer. + (+) ListenCpltCallback : callback for end of listen mode. + (+) MemTxCpltCallback : callback for Memory transmission end of transfer. + (+) MemRxCpltCallback : callback for Memory reception end of transfer. + (+) ErrorCallback : callback for error detection. + (+) AbortCpltCallback : callback for abort completion process. + (+) MspInitCallback : callback for Msp Init. + (+) MspDeInitCallback : callback for Msp DeInit. + [..] + For callback AddrCallback use dedicated register callbacks : @ref HAL_I2C_UnRegisterAddrCallback(). + [..] + By default, after the @ref HAL_I2C_Init() and when the state is @ref HAL_I2C_STATE_RESET + all callbacks are set to the corresponding weak functions: + examples @ref HAL_I2C_MasterTxCpltCallback(), @ref HAL_I2C_MasterRxCpltCallback(). + Exception done for MspInit and MspDeInit functions that are + reset to the legacy weak functions in the @ref HAL_I2C_Init()/ @ref HAL_I2C_DeInit() only when + these callbacks are null (not registered beforehand). + If MspInit or MspDeInit are not null, the @ref HAL_I2C_Init()/ @ref HAL_I2C_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state. + [..] + Callbacks can be registered/unregistered in @ref HAL_I2C_STATE_READY state only. + Exception done MspInit/MspDeInit functions that can be registered/unregistered + in @ref HAL_I2C_STATE_READY or @ref HAL_I2C_STATE_RESET state, + thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit. + Then, the user first registers the MspInit/MspDeInit user callbacks + using @ref HAL_I2C_RegisterCallback() before calling @ref HAL_I2C_DeInit() + or @ref HAL_I2C_Init() function. + [..] + When the compilation flag USE_HAL_I2C_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registration feature is not available and all callbacks + are set to the corresponding weak functions. + + + *** I2C Workarounds linked to Silicon Limitation *** + ==================================================== + [..] + Below the list of all silicon limitations implemented for HAL on PY32F040 product. + (@) See ErrataSheet to know full silicon limitation list of your product. + + (+) Workarounds Implemented inside I2C HAL Driver + (++) Wrong data read into data register (Polling and Interrupt mode) + (++) Start cannot be generated after a misplaced Stop + (++) Some software events must be managed before the current byte is being transferred: + Workaround: Use DMA in general, except when the Master is receiving a single byte. + For Interupt mode, I2C should have the highest priority in the application. + (++) Mismatch on the "Setup time for a repeated Start condition" timing parameter: + Workaround: Reduce the frequency down to 88 kHz or use the I2C Fast-mode if + supported by the slave. + (++) Data valid time (tVD;DAT) violated without the OVR flag being set: + Workaround: If the slave device allows it, use the clock stretching mechanism + by programming NoStretchMode = I2C_NOSTRETCH_DISABLE in @ref HAL_I2C_Init. + + [..] + (@) You can refer to the I2C HAL driver header file for more useful macros + + @endverbatim + + ****************************************************************************** + * @attention + * + *

=============================================================================== + [..] + The I2S HAL driver can be used as follow: + + (#) Declare a I2S_HandleTypeDef handle structure. + (#) Initialize the I2S low level resources by implement the HAL_I2S_MspInit() API: + (##) Enable the SPIx interface clock. + (##) I2S pins configuration: + (+++) Enable the clock for the I2S GPIOs. + (+++) Configure these I2S pins as alternate function pull-up. + (##) NVIC configuration if you need to use interrupt process (HAL_I2S_Transmit_IT() + and HAL_I2S_Receive_IT() APIs). + (+++) Configure the I2Sx interrupt priority. + (+++) Enable the NVIC I2S IRQ handle. + (##) DMA Configuration if you need to use DMA process (HAL_I2S_Transmit_DMA() + and HAL_I2S_Receive_DMA() APIs: + (+++) Declare a

the DMA Tx/Rx Stream/Channel. + (+++) Associate the initialized DMA handle to the I2S DMA Tx/Rx handle. + (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the + DMA Tx/Rx Stream/Channel. + + (#) Program the Mode, Standard, Data Format, MCLK Output, Audio frequency and Polarity + using HAL_I2S_Init() function. + + -@- The specific I2S interrupts (Transmission complete interrupt, + RXNE interrupt and Error Interrupts) will be managed using the macros + __HAL_I2S_ENABLE_IT() and __HAL_I2S_DISABLE_IT() inside the transmit and receive process. + -@- The I2SxCLK source is the system clock (provided by the HSI, the HSE or the PLL, and sourcing the AHB clock). + For connectivity line devices, the I2SxCLK source can be either SYSCLK or the PLL3 VCO (2 x PLL3CLK) clock + in order to achieve the maximum accuracy. + -@- Make sure that either: + (+@) External clock source is configured after setting correctly + the define constant HSE_VALUE in the PY32F040_hal_conf.h file. + + (#) Three mode of operations are available within this driver : + + *** Polling mode IO operation *** + ================================= + [..] + (+) Send an amount of

not + + [..] + (@) You can refer to the I2S HAL driver header file for more useful macros + + *** I2S HAL driver macros list *** + =================================== + [..] + Callback registration: + + (#) The compilation flag USE_HAL_I2S_REGISTER_CALLBACKS when set to 1U + allows the user to configure dynamically the driver callbacks. + Use Functions HAL_I2S_RegisterCallback() to register an interrupt callback. + + Function HAL_I2S_RegisterCallback() allows to register following callbacks: + (++) TxCpltCallback : I2S Tx Completed callback + (++) RxCpltCallback : I2S Rx Completed callback + (++) TxHalfCpltCallback : I2S Tx Half Completed callback + (++) RxHalfCpltCallback : I2S Rx Half Completed callback + (++) ErrorCallback : I2S Error callback + (++) MspInitCallback : I2S Msp Init callback + (++) MspDeInitCallback : I2S Msp DeInit callback + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + + (#) Use function HAL_I2S_UnRegisterCallback to reset a callback to the default + weak function. + HAL_I2S_UnRegisterCallback takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (++) TxCpltCallback : I2S Tx Completed callback + (++) RxCpltCallback : I2S Rx Completed callback + (++) TxHalfCpltCallback : I2S Tx Half Completed callback + (++) RxHalfCpltCallback : I2S Rx Half Completed callback + (++) ErrorCallback : I2S Error callback + (++) MspInitCallback : I2S Msp Init callback + (++) MspDeInitCallback : I2S Msp DeInit callback + + [..] + By default, after the HAL_I2S_Init() and when the state is HAL_I2S_STATE_RESET + all callbacks are set to the corresponding weak functions: + examples HAL_I2S_MasterTxCpltCallback(), HAL_I2S_MasterRxCpltCallback(). + Exception done for MspInit and MspDeInit functions that are + reset to the legacy weak functions in the HAL_I2S_Init()/ HAL_I2S_DeInit() only when + these callbacks are null (not registered beforehand). + If MspInit or MspDeInit are not null, the HAL_I2S_Init()/ HAL_I2S_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state. + + [..] + Callbacks can be registered/unregistered in HAL_I2S_STATE_READY state only. + Exception done MspInit/MspDeInit functions that can be registered/unregistered + in HAL_I2S_STATE_READY or HAL_I2S_STATE_RESET state, + thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit. + Then, the user first registers the MspInit/MspDeInit user callbacks + using HAL_I2S_RegisterCallback() before calling HAL_I2S_DeInit() + or HAL_I2S_Init() function. + + [..] + When the compilation define USE_HAL_I2S_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registering feature is not available + and weak (surcharged) callbacks are used. + + *** I2S Workarounds linked to Silicon Limitation *** + ==================================================== + [..] + (@) Only the 16-bit mode with no data extension can be used when the I2S + is in Master and used the PCM long synchronization mode. + + @endverbatim + ****************************************************************************** + * @attention + * + *

(+) __HAL_IRDA_ENABLE_IT: Enable the specified IRDA interrupt + (+) __HAL_IRDA_DISABLE_IT: Disable the specified IRDA interrupt + (+) __HAL_IRDA_GET_IT_SOURCE: Check whether the specified IRDA interrupt has occurred or not + + [..] + (@) You can refer to the IRDA HAL driver header file for more useful macros + + ##### Callback registration ##### + ================================== + + [..] + The compilation define USE_HAL_IRDA_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + + [..] + Use Function @ref HAL_IRDA_RegisterCallback() to register a user callback. + Function @ref HAL_IRDA_RegisterCallback() allows to register following callbacks: + (+) TxHalfCpltCallback : Tx Half Complete Callback. + (+) TxCpltCallback : Tx Complete Callback. + (+) RxHalfCpltCallback : Rx Half Complete Callback. + (+) RxCpltCallback : Rx Complete Callback. + (+) ErrorCallback : Error Callback. + (+) AbortCpltCallback : Abort Complete Callback. + (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback. + (+) AbortReceiveCpltCallback : Abort Receive Complete Callback. + (+) MspInitCallback : IRDA MspInit. + (+) MspDeInitCallback : IRDA MspDeInit. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + [..] + Use function @ref HAL_IRDA_UnRegisterCallback() to reset a callback to the default + weak (surcharged) function. + @ref HAL_IRDA_UnRegisterCallback() takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) TxHalfCpltCallback : Tx Half Complete Callback. + (+) TxCpltCallback : Tx Complete Callback. + (+) RxHalfCpltCallback : Rx Half Complete Callback. + (+) RxCpltCallback : Rx Complete Callback. + (+) ErrorCallback : Error Callback. + (+) AbortCpltCallback : Abort Complete Callback. + (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback. + (+) AbortReceiveCpltCallback : Abort Receive Complete Callback. + (+) MspInitCallback : IRDA MspInit. + (+) MspDeInitCallback : IRDA MspDeInit. + + [..] + By default, after the @ref HAL_IRDA_Init() and when the state is HAL_IRDA_STATE_RESET + all callbacks are set to the corresponding weak (surcharged) functions: + examples @ref HAL_IRDA_TxCpltCallback(), @ref HAL_IRDA_RxHalfCpltCallback(). + Exception done for MspInit and MspDeInit functions that are respectively + reset to the legacy weak (surcharged) functions in the @ref HAL_IRDA_Init() + and @ref HAL_IRDA_DeInit() only when these callbacks are null (not registered beforehand). + If not, MspInit or MspDeInit are not null, the @ref HAL_IRDA_Init() and @ref HAL_IRDA_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand). + + [..] + Callbacks can be registered/unregistered in HAL_IRDA_STATE_READY state only. + Exception done MspInit/MspDeInit that can be registered/unregistered + in HAL_IRDA_STATE_READY or HAL_IRDA_STATE_RESET state, thus registered (user) + MspInit/DeInit callbacks can be used during the Init/DeInit. + In that case first register the MspInit/MspDeInit user callbacks + using @ref HAL_IRDA_RegisterCallback() before calling @ref HAL_IRDA_DeInit() + or @ref HAL_IRDA_Init() function. + + [..] + When The compilation define USE_HAL_IRDA_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registration feature is not available + and weak (surcharged) callbacks are used. + + @endverbatim + [..] + (@) Additionnal remark: If the parity is enabled, then the MSB bit of the data written + in the data register is transmitted but is changed by the parity bit. + Depending on the frame length defined by the M bit (8-bits or 9-bits), + the possible IRDA frame formats are as listed in the following table: + +-------------------------------------------------------------+ + | M bit | PCE bit | IRDA frame | + |---------------------|---------------------------------------| + | 0 | 0 | | SB | 8 bit data | 1 STB | | + |---------|-----------|---------------------------------------| + | 0 | 1 | | SB | 7 bit

This function + configures mainly: + (++) The instance: LPTIM1 or LPTIM2. + (++) Clock: the counter clock. + (+++) Source : it can be either the ULPTIM input (IN1) or one of + the internal clock; (APB, LSE, LSI or HSI). + (+++) Prescaler: select the clock divider. + (#)Six modes are available: + + (++) PWM Mode: To generate a PWM signal with specified period and pulse, + call HAL_LPTIM_PWM_Start() or HAL_LPTIM_PWM_Start_IT() for interruption + mode. + + (++) One Pulse Mode: To generate pulse with specified width in response + to a stimulus, call HAL_LPTIM_OnePulse_Start() or + HAL_LPTIM_OnePulse_Start_IT() for interruption mode. + + (++) Set once Mode: In this mode, the output changes the level (from + low level to high level if the output polarity is configured high, else + the opposite) when a compare match occurs. To start this mode, call + HAL_LPTIM_SetOnce_Start() or HAL_LPTIM_SetOnce_Start_IT() for + interruption mode. + + (++) Encoder Mode: To use the encoder interface call + HAL_LPTIM_Encoder_Start() or HAL_LPTIM_Encoder_Start_IT() for + interruption mode. Only available for LPTIM1 instance. + + (++) Time out Mode: an active edge on one selected trigger input rests + the counter. The first trigger event will start the timer, any + successive trigger event will reset the counter and the timer will + restart. To start this mode call HAL_LPTIM_TimeOut_Start_IT() or + HAL_LPTIM_TimeOut_Start_IT() for interruption mode. + + (++) Counter Mode: counter can be used to count external events on + the LPTIM Input1 or it can be used to count internal clock cycles. + To start this mode, call HAL_LPTIM_Counter_Start() or + HAL_LPTIM_Counter_Start_IT() for interruption mode. + + + (#) User can stop any process by calling the corresponding API: + HAL_LPTIM_Xxx_Stop() or HAL_LPTIM_Xxx_Stop_IT() if the process is + already started in interruption mode. + + (#) De-initialize the LPTIM peripheral using HAL_LPTIM_DeInit(). + + *** Callback registration *** + ============================================= + [..] + The compilation define USE_HAL_LPTIM_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + [..] + Use Function @ref HAL_LPTIM_RegisterCallback() to register a callback. + @ref HAL_LPTIM_RegisterCallback() takes as parameters the HAL peripheral handle, + the Callback ID and a pointer to the user callback function. + [..] + Use function @ref HAL_LPTIM_UnRegisterCallback() to reset a callback to the + default weak function. + @ref HAL_LPTIM_UnRegisterCallback takes as parameters the HAL peripheral handle, + and the Callback ID. + [..] + These functions allow to register/unregister following callbacks: + + (+) MspInitCallback : LPTIM Base Msp Init Callback. + (+) MspDeInitCallback : LPTIM Base Msp DeInit Callback. + (+) CompareMatchCallback : Compare match Callback. + (+) AutoReloadMatchCallback : Auto-reload match Callback. + (+) TriggerCallback : External trigger event detection Callback. + (+) CompareWriteCallback : Compare register write complete Callback. + (+) AutoReloadWriteCallback : Auto-reload register write complete Callback. + (+) DirectionUpCallback : Up-counting direction change Callback. + (+) DirectionDownCallback : Down-counting direction change Callback. + + [..] + By default, after the Init and when the state is HAL_LPTIM_STATE_RESET + all interrupt callbacks are set to the corresponding weak functions: + examples @ref HAL_LPTIM_TriggerCallback(), @ref HAL_LPTIM_CompareMatchCallback(). + + [..] + Exception done for MspInit and MspDeInit functions that are reset to the legacy weak + functionalities in the Init/DeInit only when these callbacks are null + (not registered beforehand).

All the features supported by V2 + (other families) will be not supported on F1. + [..] As on V2, main RTC features are managed by HW. But on F1, date feature is completely + managed by SW. + [..] Then, there are some restrictions compared to other families: + (+) Only format 24 hours supported in HAL (format 12 hours not supported) + (+) Date is saved in SRAM. Then, when MCU is in STOP or STANDBY mode, date will be lost. + User should implement a way to save date before entering in low power mode (an + example is provided with firmware package based on backup registers) + (+) Date is automatically updated each time a HAL_RTC_GetTime or HAL_RTC_GetDate is called. + (+) Alarm detection is limited to 1 day. It will expire only 1 time (no alarm repetition, need + to program a new alarm) + + ##### Backup Domain Operating Condition ##### + ============================================================================== + [..] The real-time clock (RTC) and the RTC backup registers can be powered + from the VBAT voltage when the main VDD supply is powered off. + To retain the content of the RTC backup registers and supply the RTC + when VDD is turned off, VBAT pin can be connected to an optional + standby voltage supplied by a battery or by another source. + + [..] To allow the RTC operating even when the main digital supply (VDD) is turned + off, the VBAT pin powers the following blocks: + (#) The RTC + (#) The LSE oscillator + (#) The backup SRAM when the low power backup regulator is enabled + (#) PC13 to PC15 I/Os, plus PI8 I/O (when available) + + [..] When the backup domain is supplied by VDD (analog switch connected to VDD), + the following pins are available: + (+) PC13 can be used as a Tamper pin + + [..] When the backup domain is supplied by VBAT (analog switch connected to VBAT + because VDD is not present), the following pins are available: + (+) PC13 can be used as the Tamper pin + + ##### Backup Domain Reset ##### + ================================================================== + [..] The backup domain reset sets all RTC registers and the RCC_BDCR register + to their reset values. + [..] A backup domain reset is generated when one of the following events occurs: + (#) Software reset, triggered by setting the BDRST bit in the + RCC Backup domain control register (RCC_BDCR). + (#) VDD or VBAT power on, if both supplies have previously been powered off. + (#) Tamper detection event resets all data backup registers. + + ##### Backup Domain Access ##### + ================================================================== + [..] After reset, the backup domain (RTC registers, RTC backup data + registers and backup SRAM) is protected against possible unwanted write + accesses. + [..] To enable access to the RTC Domain and RTC registers, proceed as follows: + (+) Call the function HAL_RCCEx_PeriphCLKConfig in using RCC_PERIPHCLK_RTC for + PeriphClockSelection and select RTCClockSelection (LSE, LSI or HSE) + (+) Enable the BKP clock in using __HAL_RCC_BKP_CLK_ENABLE() + + ##### RTC and low power modes ##### + ================================================================== + [..] The MCU can be woken up from a low power mode by an RTC alternate + function. + [..] The RTC alternate functions are the RTC alarms (Alarm A), + and RTC tamper event detection. + These RTC alternate functions can wake up the system from the Stop and + Standby low power modes. + [..] The system can also wake up from low power modes without depending + on an external interrupt (Auto-wakeup mode), by using the RTC alarm. + + *** Callback registration *** + ============================================= + [..] + The compilation define USE_HAL_RTC_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + Use Function @ref HAL_RTC_RegisterCallback() to register an interrupt callback. + + [..] + Function @ref HAL_RTC_RegisterCallback() allows to register following callbacks: + (+) AlarmAEventCallback : RTC Alarm A Event callback. + (+) MspInitCallback : RTC MspInit callback. + (+) MspDeInitCallback : RTC MspDeInit callback. + [..] + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + [..] + Use function @ref HAL_RTC_UnRegisterCallback() to reset a callback to the default + weak function. + @ref HAL_RTC_UnRegisterCallback() takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) AlarmAEventCallback : RTC Alarm A Event callback. + (+) MspInitCallback : RTC MspInit callback. + (+) MspDeInitCallback : RTC MspDeInit callback. + [..] + By default, after the @ref HAL_RTC_Init() and when the state is HAL_RTC_STATE_RESET, + all callbacks are set to the corresponding weak functions : + example @ref AlarmAEventCallback(). + Exception done for MspInit and MspDeInit callbacks that are reset to the legacy weak function + in the @ref HAL_RTC_Init()/@ref HAL_RTC_DeInit() only when these callbacks are null + (not registered beforehand). + If not, MspInit or MspDeInit are not null, @ref HAL_RTC_Init()/@ref HAL_RTC_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand) + [..] + Callbacks can be registered/unregistered in HAL_RTC_STATE_READY state only. + Exception done MspInit/MspDeInit that can be registered/unregistered + in HAL_RTC_STATE_READY or HAL_RTC_STATE_RESET state, + thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit. + In that case first register the MspInit/MspDeInit user callbacks + using @ref HAL_RTC_RegisterCallback() before calling @ref HAL_RTC_DeInit() + or @ref HAL_RTC_Init() function. + [..] + When The compilation define USE_HAL_RTC_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registration feature is not available and all callbacks + are set to the corresponding weak functions. + @endverbatim +

============================================================================== + ##### How to use this driver ##### + ============================================================================== + [..] + The SMARTCARD HAL driver can be used as follows: + + (#) Declare a SMARTCARD_HandleTypeDef handle structure. + (#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit() API: + (##) Enable the interface clock of the USARTx associated to the SMARTCARD. + (##) SMARTCARD pins configuration: + (+++) Enable the clock for the SMARTCARD GPIOs. + (+++) Configure SMARTCARD pins as alternate function pull-up. + (##) NVIC configuration if you need to use interrupt process (HAL_SMARTCARD_Transmit_IT() + and HAL_SMARTCARD_Receive_IT() APIs): + (+++) Configure the USARTx interrupt priority. + (+++) Enable the NVIC USART IRQ handle. + (##) DMA Configuration if you need to use DMA process (HAL_SMARTCARD_Transmit_DMA() + and HAL_SMARTCARD_Receive_DMA() APIs): + (+++) Declare a DMA handle structure for the Tx/Rx channel. + (+++) Enable the DMAx interface clock. + (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters. + (+++) Configure the DMA Tx/Rx channel. + (+++) Associate the initialized DMA handle to the SMARTCARD DMA Tx/Rx handle. + (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx channel. + (+++) Configure the USARTx interrupt priority and enable the NVIC USART IRQ handle + (used for last byte sending completion detection in DMA non circular mode) + + (#) Program the Baud Rate, Word Length , Stop Bit, Parity, Hardware + flow control and Mode(Receiver/Transmitter) in the SMARTCARD Init structure. + + (#) Initialize the SMARTCARD registers by calling the HAL_SMARTCARD_Init() API: + (++) These APIs configure also the low level Hardware GPIO, CLOCK, CORTEX...etc) + by calling the customized HAL_SMARTCARD_MspInit() API. + [..] + (@) The specific SMARTCARD interrupts (Transmission complete interrupt, + RXNE interrupt and Error Interrupts) will be managed using the macros + __HAL_SMARTCARD_ENABLE_IT() and __HAL_SMARTCARD_DISABLE_IT() inside the transmit and receive process. + + [..] + Three operation modes are available within this driver : + + *** Polling mode IO operation *** + ================================= + [..] + (+) Send an amount of data in blocking mode using HAL_SMARTCARD_Transmit() + (+) Receive an amount of data in blocking mode using HAL_SMARTCARD_Receive() + + *** Interrupt mode IO operation *** + =================================== + [..] + (+) Send an amount of data in non blocking mode using HAL_SMARTCARD_Transmit_IT() + (+) At transmission end of transfer HAL_SMARTCARD_TxCpltCallback is executed and user can + add his own code by customization of function pointer HAL_SMARTCARD_TxCpltCallback + (+) Receive an amount of data in non blocking mode using HAL_SMARTCARD_Receive_IT() + (+) At reception end of transfer HAL_SMARTCARD_RxCpltCallback is executed and user can + add his own code by customization of function pointer HAL_SMARTCARD_RxCpltCallback + (+) In case of transfer Error, HAL_SMARTCARD_ErrorCallback() function is executed and user can + add his own code by customization of function pointer HAL_SMARTCARD_ErrorCallback + + *** DMA mode IO operation *** + ============================== + [..] + (+) Send an amount of data in non blocking mode (DMA) using HAL_SMARTCARD_Transmit_DMA() + (+) At transmission end of transfer HAL_SMARTCARD_TxCpltCallback is executed and user can + add his own code by customization of function pointer HAL_SMARTCARD_TxCpltCallback + (+) Receive an amount of data in non blocking mode (DMA) using HAL_SMARTCARD_Receive_DMA() + (+) At reception end of transfer HAL_SMARTCARD_RxCpltCallback is executed and user can + add his own code by customization of function pointer HAL_SMARTCARD_RxCpltCallback + (+) In case of transfer Error, HAL_SMARTCARD_ErrorCallback() function is executed and user can + add his own code by customization of function pointer HAL_SMARTCARD_ErrorCallback + + *** SMARTCARD HAL driver macros list *** + ======================================== + [..] + Below the list of most used macros in SMARTCARD HAL driver. + + (+) __HAL_SMARTCARD_ENABLE: Enable the SMARTCARD peripheral + (+) __HAL_SMARTCARD_DISABLE: Disable the SMARTCARD peripheral + (+) __HAL_SMARTCARD_GET_FLAG : Check whether the specified SMARTCARD flag is set or not + (+) __HAL_SMARTCARD_CLEAR_FLAG : Clear the specified SMARTCARD pending flag + (+) __HAL_SMARTCARD_ENABLE_IT: Enable the specified SMARTCARD interrupt + (+) __HAL_SMARTCARD_DISABLE_IT: Disable the specified SMARTCARD interrupt + + [..] + (@) You can refer to the SMARTCARD HAL driver header file for more useful macros + + ##### Callback registration ##### + ================================== + + [..] + The compilation define USE_HAL_SMARTCARD_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + + [..] + Use Function @ref HAL_SMARTCARD_RegisterCallback() to register a user callback. + Function @ref HAL_SMARTCARD_RegisterCallback() allows to register following callbacks: + (+) TxCpltCallback : Tx Complete Callback. + (+) RxCpltCallback : Rx Complete Callback. + (+) ErrorCallback : Error Callback. + (+) AbortCpltCallback : Abort Complete Callback. + (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback. + (+) AbortReceiveCpltCallback : Abort Receive Complete Callback. + (+) MspInitCallback : SMARTCARD MspInit. + (+) MspDeInitCallback : SMARTCARD MspDeInit. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + [..] + Use function @ref HAL_SMARTCARD_UnRegisterCallback() to reset a callback to the default + weak (surcharged) function. + @ref HAL_SMARTCARD_UnRegisterCallback() takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) TxCpltCallback : Tx Complete Callback. + (+) RxCpltCallback : Rx Complete Callback. + (+) ErrorCallback : Error Callback. + (+) AbortCpltCallback : Abort Complete Callback. + (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback. + (+) AbortReceiveCpltCallback : Abort Receive Complete Callback. + (+) MspInitCallback : SMARTCARD MspInit. + (+) MspDeInitCallback : SMARTCARD MspDeInit. + + [..] + By default, after the @ref HAL_SMARTCARD_Init() and when the state is HAL_SMARTCARD_STATE_RESET + all callbacks are set to the corresponding weak (surcharged) functions: + examples @ref HAL_SMARTCARD_TxCpltCallback(), @ref HAL_SMARTCARD_RxCpltCallback(). + Exception done for MspInit and MspDeInit functions that are respectively + reset to the legacy weak (surcharged) functions in the @ref HAL_SMARTCARD_Init() + and @ref HAL_SMARTCARD_DeInit() only when these callbacks are null (not registered beforehand). + If not, MspInit or MspDeInit are not null, the @ref HAL_SMARTCARD_Init() and @ref HAL_SMARTCARD_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand). + + [..] + Callbacks can be registered/unregistered in HAL_SMARTCARD_STATE_READY state only. + Exception done MspInit/MspDeInit that can be registered/unregistered + in HAL_SMARTCARD_STATE_READY or HAL_SMARTCARD_STATE_RESET state, thus registered (user) + MspInit/DeInit callbacks can be used during the Init/DeInit. + In that case first register the MspInit/MspDeInit user callbacks + using @ref HAL_SMARTCARD_RegisterCallback() before calling @ref HAL_SMARTCARD_DeInit() + or @ref HAL_SMARTCARD_Init() function. + + [..] + When The compilation define USE_HAL_SMARTCARD_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registration feature is not available + and weak (surcharged) callbacks are used. + + @endverbatim + ****************************************************************************** + * @attention + * + *

Initialization and de-initialization functions + * + IO operation functions + * + Peripheral Control functions + * + Peripheral State functions + * + @verbatim + ============================================================================== + ##### How to use this driver ##### + ============================================================================== + [..] + The SPI HAL driver can be used as follows: + + (#) Declare a SPI_HandleTypeDef handle structure, for example: + SPI_HandleTypeDef hspi; + + (#)Initialize the SPI low level resources by implementing the HAL_SPI_MspInit() API: + (##) Enable the SPIx interface clock + (##) SPI pins configuration + (+++) Enable the clock for the SPI GPIOs + (+++) Configure these SPI pins as alternate function push-pull + (##) NVIC configuration if you need to use interrupt process + (+++) Configure the SPIx interrupt priority + (+++) Enable the NVIC SPI IRQ handle + (##) DMA Configuration if you need to use DMA process + (+++) Declare a DMA_HandleTypeDef handle structure for the transmit or receive Stream/Channel + (+++) Enable the DMAx clock + (+++) Configure the DMA handle parameters + (+++) Configure the DMA Tx or Rx Stream/Channel + (+++) Associate the initialized hdma_tx(or _rx) handle to the hspi DMA Tx or Rx handle + (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx or Rx Stream/Channel + + (#) Program the Mode, BidirectionalMode , Data size, Baudrate Prescaler, NSS + management, Clock polarity and phase, FirstBit and CRC configuration in the hspi Init structure. + + (#) Initialize the SPI registers by calling the HAL_SPI_Init() API: + (++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc) + by calling the customized HAL_SPI_MspInit() API. + [..] + Circular mode restriction: + (#) The DMA circular mode cannot be used when the SPI is configured in these modes: + (##) Master 2Lines RxOnly + (##) Master 1Line Rx + (#) The CRC feature is not managed when the DMA circular mode is enabled + (#) When the SPI DMA Pause/Stop features are used, we must use the following APIs + the HAL_SPI_DMAPause()/ HAL_SPI_DMAStop() only under the SPI callbacks + [..] + Master Receive mode restriction: + (#) In Master unidirectional receive-only mode (MSTR =1, BIDIMODE=0, RXONLY=1) or + bidirectional receive mode (MSTR=1, BIDIMODE=1, BIDIOE=0), to ensure that the SPI + does not initiate a new transfer the following procedure has to be respected: + (##) HAL_SPI_DeInit() + (##) HAL_SPI_Init() + [..] + Callback registration: + + (#) The compilation flag USE_HAL_SPI_REGISTER_CALLBACKS when set to 1U + allows the user to configure dynamically the driver callbacks. + Use Functions HAL_SPI_RegisterCallback() to register an interrupt callback. + + Function HAL_SPI_RegisterCallback() allows to register following callbacks: + (++) TxCpltCallback : SPI Tx Completed callback + (++) RxCpltCallback : SPI Rx Completed callback + (++) TxRxCpltCallback : SPI TxRx Completed callback + (++) TxHalfCpltCallback : SPI Tx Half Completed callback + (++) RxHalfCpltCallback : SPI Rx Half Completed callback + (++) TxRxHalfCpltCallback : SPI TxRx Half Completed callback + (++) ErrorCallback : SPI Error callback + (++) AbortCpltCallback : SPI Abort callback + (++) MspInitCallback : SPI Msp Init callback + (++) MspDeInitCallback : SPI Msp DeInit callback + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + + (#) Use function HAL_SPI_UnRegisterCallback to reset a callback to the default + weak function. + HAL_SPI_UnRegisterCallback takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (++) TxCpltCallback : SPI Tx Completed callback + (++) RxCpltCallback : SPI Rx Completed callback + (++) TxRxCpltCallback : SPI TxRx Completed callback + (++) TxHalfCpltCallback : SPI Tx Half Completed callback + (++) RxHalfCpltCallback : SPI Rx Half Completed callback + (++) TxRxHalfCpltCallback : SPI TxRx Half Completed callback + (++) ErrorCallback : SPI Error callback + (++) AbortCpltCallback : SPI Abort callback + (++) MspInitCallback : SPI Msp Init callback + (++) MspDeInitCallback : SPI Msp DeInit callback + + [..] + By default, after the HAL_SPI_Init() and when the state is HAL_SPI_STATE_RESET + all callbacks are set to the corresponding weak functions: + examples HAL_SPI_MasterTxCpltCallback(), HAL_SPI_MasterRxCpltCallback(). + Exception done for MspInit and MspDeInit functions that are + reset to the legacy weak functions in the HAL_SPI_Init()/ HAL_SPI_DeInit() only when + these callbacks are null (not registered beforehand). + If MspInit or MspDeInit are not null, the HAL_SPI_Init()/ HAL_SPI_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state. + + [..] + Callbacks can be registered/unregistered in HAL_SPI_STATE_READY state only. + Exception done MspInit/MspDeInit functions that can be registered/unregistered + in HAL_SPI_STATE_READY or HAL_SPI_STATE_RESET state, + thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit. + Then, the user first registers the MspInit/MspDeInit user callbacks + using HAL_SPI_RegisterCallback() before calling HAL_SPI_DeInit() + or HAL_SPI_Init() function. + + [..] + When the compilation define USE_HAL_PPP_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registering feature is not available + and weak (surcharged) callbacks are used. + + [..] + Using the HAL it is not possible to reach all supported SPI frequency with the different SPI Modes, + the following table resume the max SPI frequency reached with data size 8bits/16bits, + according to frequency of the APBx Peripheral Clock (fPCLK) used by the SPI instance. + +

more useful macros + + ##### Callback registration ##### + ================================== + + [..] + The compilation define USE_HAL_USART_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + + [..] + Use Function @ref HAL_USART_RegisterCallback() to register a user callback. + Function @ref HAL_USART_RegisterCallback() allows to register following callbacks: + (+) TxHalfCpltCallback : Tx Half Complete Callback. + (+) TxCpltCallback : Tx Complete Callback. + (+) RxHalfCpltCallback : Rx Half Complete Callback. + (+) RxCpltCallback : Rx Complete Callback. + (+) TxRxCpltCallback : Tx Rx Complete Callback. + (+) ErrorCallback : Error Callback. + (+) AbortCpltCallback : Abort Complete Callback. + (+) MspInitCallback : USART MspInit. + (+) MspDeInitCallback : USART MspDeInit. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + [..] + Use function @ref HAL_USART_UnRegisterCallback() to reset a callback to the default + weak (surcharged) function. + @ref HAL_USART_UnRegisterCallback() takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) TxHalfCpltCallback : Tx Half Complete Callback. + (+) TxCpltCallback : Tx Complete Callback. + (+) RxHalfCpltCallback : Rx Half Complete Callback. + (+) RxCpltCallback : Rx Complete Callback. + (+) TxRxCpltCallback : Tx Rx Complete Callback. + (+) ErrorCallback : Error Callback. + (+) AbortCpltCallback : Abort Complete Callback. + (+) MspInitCallback : USART MspInit. + (+) MspDeInitCallback : USART MspDeInit. + + [..] + By default, after the @ref HAL_USART_Init() and when the state is HAL_USART_STATE_RESET + all callbacks are set to the corresponding weak (surcharged) functions: + examples @ref HAL_USART_TxCpltCallback(), @ref HAL_USART_RxHalfCpltCallback(). + Exception done for MspInit and MspDeInit functions that are respectively + reset to the legacy weak (surcharged) functions in the @ref HAL_USART_Init() + and @ref HAL_USART_DeInit() only when these callbacks are null (not registered beforehand). + If not, MspInit or MspDeInit are not null, the @ref HAL_USART_Init() and @ref HAL_USART_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand). + + [..] + Callbacks can be registered/unregistered in HAL_USART_STATE_READY state only. + Exception done MspInit/MspDeInit that can be registered/unregistered + in HAL_USART_STATE_READY or HAL_USART_STATE_RESET state, thus registered (user) + MspInit/DeInit callbacks can be used during the Init/DeInit. + In that case first register the MspInit/MspDeInit user callbacks + using @ref HAL_USART_RegisterCallback() before calling @ref HAL_USART_DeInit() + or @ref HAL_USART_Init() function. + + [..] + When The compilation define USE_HAL_USART_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registration feature is not available + and weak (surcharged) callbacks are used. + + @endverbatim + [..] + (@) Additionnal remark: If the parity is enabled, then the MSB bit of the data written + in the data register is transmitted but is changed by the parity bit. + Depending on the frame length defined by the M bit (8-bits or 9-bits), + the possible USART frame formats are as listed in the following
