dudmuck 10:a3e2c558c003 20 The MCU can be woken up from low-power mode by an RTC Alarm event, an RTC

dudmuck 10:a3e2c558c003 28 function
dudmuck 10:a3e2c558c003 29 (+++) Configure the RTC to generate the RTC alarm using the HAL_RTC_Init()
dudmuck 10:a3e2c558c003 30 and HAL_RTC_SetTime() functions.
