+/******************************************************************************
+ * @file    app_shake_wake.c
+ * @brief   PA3 vibration-switch wake detector.
+ *
+ * The fitted switch is normally closed to ground.  A vibration opens the
+ * contact, so PA3 goes high, then returns low when the contact closes again.
+ * A wake is accepted only after the high level has been stable for the
+ * re-arm interval and is generated on the following high-to-low transition.
