    Nov 13, 2020 · I also understand Periodic Alarm logic and to handle the requirement I've, I incremented alarm periodically based on second, minutes and hour value. Using the below code, I achieved generating periodic interrupt using alarm but somehow millisecond part is not working as expected. If you could help me to resolve this issue, it would be of great ...

    Oct 30, 2023 · It's about Alarm Mask. Alarm Mask is used for ignore that field to compare with your alarm time. As your config, You have no mask in any field so RTC are going to alarm on every 0:0:20.000 on Monday. and If you want to alarm at second 20th every minute, you should try to mask in another field except second field.

    Sep 25, 2023 · Wake up with internal interrupt raise with the RTC alarm. For this test, It’s better if you read this article first “STM32: internal RTC, clock and battery backup (VBAT)” to understand better how to work the internal RTC. We want to try to set an alarm to wake the device, and to do this the RTC library helps us.
