TM4C1294NCPDT: Use RTC peripheral to obtain high time accuracy

Davide Vergnani
Prodigy 20 points
Part Number: TM4C1294NCPDT
Other Parts Discussed in Thread: EK-TM4C1294XL

Hi,

I'm new on TI Tiva C microcontroller. Now, I'm trying to use RTC to make an feature on my software when the time accuracy is very important.

In the datasheet, I didn't find an dedicated section. I need to learn how to use it, how  does it works. 

Somebody can post some kind example on RTC usage. I need to understand what TI Tiva SDK API use to handle that peripheral.

P.S. Exist any document, relating to RTC, like User Manual or application Note?

    Hello Davide,

    The datasheet section for the RTC is part of the Hibernation Module chapter.

    In TivaWare we have two Hiberate examples under C:\ti\TivaWare_C_Series-2.2.0.295\examples\boards\ek-tm4c1294xl.

    Those are deeply commented and should get you all the information you need to get started with the RTC.

    Best Regards,
