Real-Time-Clock (RTC), how do I know it is working properly?

[Member]

I think I got the setup for the Real-Time-Clock (RTC), but how do I verify it is working?

Is there a way to output the timestamps or check through a file? I am using the STM32WB55 Nucleo Board, and currently using the STM32 IDE.

Just read out the RTC registers in the debugger. Time and subseconds should change when reading out repeatedly.
