Hi,

i need two precise alarms i can set on my STM32F4 which will also be save when only the Backup domain is powered by a small battery. How many alarms can i have on the RTC of STM32F4? What would be my other options?

Thanks,

Patrick

Hello Patrick,

RTC in STM32F407VG MCU allows to have two alarms: Alarm A and Alarm B. In fact all devices from STM32F4 family have two alarms.
