RTC Automatic Periodic Wake up in STM32H503RBT6 controller

[Mohan30]

Hello everyone,

I am currently working on the (STM32H503RBT6)RTC periodic wakeup part (I did it in 10s(bare metal programing) ) but this is not enough timing so I want to change 1 hour or more than 1 hour. actually, I tried to do it, but I can't find the solutions, so please guide me on the correct way to find the solutions

Thanks.

Hi,

That's easy, just set the Prescaler and RTC_WUTR appropriately...

Kind regards

Hi @PGump.1 ,  actually I wrote bare-metal program so still confusing to work on it, can you please suggest any baremetal program for periodic wakeup.
thanks

Hi,

You say the timer wakes up at 10 second intervals. It looks like your code sets the timer to 60 seconds. Is that the problem?

What is PA0 connected to? A switch?

Kind regards
