In STMCubeMX for stm32F103CBT6, i can not set the time of RTC more than 12 !!! it shows:


Hours must be between 1 and 12.


Hour Format is 12H "


but in the Alaram value field, it can be 0-23 !!! :


Hours_A must be between 0 and 23."


Why i can't set the RTC houre in 24Hours format ?!

is it only in 12hours format ?! How to find if it's AM or PM ?!!! will it alarm twice a day if i set it on 10 i.e ? (once 10AM and once 10PM ?) how about if i set alarm hour on 15 i.e ?! ....

seems there is a problem here ...
