TM4C1294NCPDT: TM4C RTC calendar error Months of 31 days

Cesar Pantoja

Part Number: TM4C1294NCPDT

I am working on a development which should include a clock and a calendar, its a custom board and I have configured the RTC modules for the current date and time

but when the month has 31 days and is the 30th day change to the 1st of the following month, how do I set the calendar to contain the 31-day months?

thanks

Hi,
I will expect this to be handled by the Hibernation RTC module. For example, in January there will be 31 days, Feb with 28 days, March with 30 days and so on. The hardware will control the amount of days to count before rolling over to the next month based on which month you are in.

Hello,

thank you for your answer, I discovered that the months begin at 0, ie January equals month 0 and not month 1 as I assumed, so the error.
