In my system, I initialised two interrupts for wake-up from STOP2 mode, after exiting STOP2 mode, how do I know that the system is waking up by RTC timer or interrupt pin? Is there any variable that I can check after waking up to find the reason why ...

I do have problem to check wake up flag after wake-up from RTC timer or interrupt pin. This is my code block to check flag after wake-up: void InitiateMode(int timeValue) { turnOffPeripherals(); timeValue = getTimeValue(timeValue); printf("\ng...

I am using STM32L476RG, actually I don't get it, I already tried to check flag before and after using this code: if (__HAL_RTC_WAKEUPTIMER_GET_FLAG(&hrtc, RTC_FLAG_WUTF) != RESET) { // Wake-up event detected, clear the flag __HAL_RTC_WAKEU...

Thanks for the reply, I just checked the initial state with the code added in void InitiateMode below: // Check RTC Wake-Up Timer Flag if (__HAL_RTC_WAKEUPTIMER_GET_FLAG(&hrtc, RTC_FLAG_WUTF) == SET) { // Your code to turn on the LED or per...
