TM4C1297NCZAD: RTC Calendar

Suzanne Lim

Part Number: TM4C1297NCZAD

HI,

I am looking for a sample code for RTC calendar. Can you provide a link to the sample code?

Does this function only works for waking up on hibernation? Is this possible to be used as alarm while running?

How to sync the date for this RTC?

Thanks

Take a look at the TivaWare example in: C:\ti\TivaWare_C_Series-2.2.0.295\examples\boards\ek-tm4c1294xl\hibernate_calendar

The calendar match function can be used to generate an interrupt. See a description of the TivaWare Hibernation module functions in chapter 15 of:

HI Bob,

Thanks for the info. Do you know how to sync the date for this RTC?

There is no general answer to your question. It is very application dependent. There is a SNTP LWIP ethernet example in this application report:
