Introduction The real-time clock (RTC) can be used as a source to periodically wake-up the microcontroller, perform necessary tasks, and then return to low-power mode. Furthermore, the RTC can be used to calculate the elapsed time while the microco...

Hello @Kmax18, have you been able to solve this issue?

Sarra.S · 2025-03-27

Hello @dlagyals I don't think the issue is related to the code you've shared Maybe check the wakeup pin configuration, it should be set as an input with pull-up or pull-down resistor Also, have you verified that LSE is working independently?

Hello @auuais, thank you for the detailed explanation! Before diving deep into the behavior you're observing, could you try and run this example to make sure it is functional on your side: STM32CubeG0/Projects/NUCLEO-G0B1RE/Examples/GPIO/GPIO_EXTI ...

Hello @XeMan, Indeed, the STM32H563 uses emulated EEPROM by writing to FLASH However, I want to highlight that in your code, the value 0 means that EWI is disabled: hiwdg.Init.EWI = 0;

Hello @Lukas4, The update interrupt is triggered when the counter reaches the ARR value, which you can set to the number of pulses you want to count before the interrupt occurs.
