Der Sir/Mam,

I want to use internal RTC for my project in which i want to send RTC values like Minute ,Hour, Seconds with day with respect to ADC values ( in other words i want to know event time). Way of programming is Energia or TivaWare (Energia is preferred) if Energia is not sufficient then how to use TivaWare for programming.I am not familiar with TivaWare so i dont know how to start working on it and then how to achieve my specified goal via TivaWare.

thanx a lot

Hi Vaibhav,

If you are going to use TivaWare I advise you first starting with the basics instead of going straight to the RTC.
With energia I have this using TIvaWare in the Energia IDE:
forum.stellarisiti.com/.../2005-tm4c129-hibernation-rtc-and-calendar-mode

I made a very short library that might help, though someone reported an error that I never ended up fixing:
forum.stellarisiti.com/.../2026-calendar-mode-with-tm4c1294

Now if you want to make with TivaWare you can use a General Purpose Timer in RTC mode or the Hibernation module which has a RTC (like it's used in the above links). But for that you have to learn first using TivaWare. You can see how Energia is limiting, there are many functions that aren't covered. Here is a starting point...
