Multiple(five) alarm time setting in stm32f0 mcu
$begingroup$
I am working on my hobbyist project and need to develop the alarm timings.
And RTC and Timer are new for me and I am confused in RTC Alarm time setting.
I need to make alarm with RTC for five different times(as we are doing in the mobile).
So, I am looking for the same thing with my mcu.
Looking forward for the kind support ...
(I am using STM32 Nucleo Board, KEIL-IDE, CubeMX)
Thanks

Check AN3371 at the official website of ST.
However, according to paragraph 2 there are only 2 alarms (A and B).
Alternatives:
- Keep 5 alarms in your own code, set the first alarm (A) as alarm 1. When this fires, program A as for the next alarm (2) etc. Alarm B is not needed.
- Do not use the alarm of the RTC, but a timer (not sure if the timer can be set for a long period).

Alternative number one is best if you want to use Low Power modes in your controller because the RTC can run on the external 32kHz crystal even if your main clock is stopped.
