* @file usr_led_status.c
|
||
* @brief 状态指示灯实现
|
||
* @author cyWu <1917507415@qq.com>
|
||
* @date 2026.08.03
|
||
* @version V1.0.0
|
||
* @history
|
||
* - V1.0.0, 2026.08.03, cyWu, 首次发布
|
||
*
|
||
* 显示规则：
|
||
* 红灯(PA8)：上电常亮；COM(DTR)打开时 1Hz 闪烁（优先于常亮）
|
||
* 绿灯(PA7)：BLE 已连接常亮；OTA 进行中 1Hz 闪烁（优先于常亮）；否则熄灭
|
||
*
|
||
* 依赖：
|
||
* - BLE：usr_get_conn_service() != 0
|
||
* - COM：cdc_is_com_open() == 1（与 Dengle 暂停语义一致）
|
||
* - OTA：usr_get_ota_status() == 0（dual_ota_idle=0 表示忙）
