Hi @@Neetee,

 

Don't double post - it is bad etiquette.  Your original post was not ignored.

Extremely sorry will not repeat it .

Can you help out i tried rtcplus library also

Have a look at this post:  http://forum.43oh.com/topic/5421-energia-library-rtc-a/

 

I haven't used it in a project, but the post states that it runs with the F5529.  It is not clear what your final objective is and whether you are trying any of this code yourself - try to get it working yourself first.  If you have specific problems then post your objective, the code and the issue / error message you are getting.  The original author may be willing to help and I will help as time permits.  I may try running it myself this evening.

I modified the code in the link above a bit and wrote a new example to demonstrate retrieval of the date and time as well as a few other features. It was not extensively tested.  To use, post all of the files into a folder called RTC_F5529 where Energia can reach it.  It is posted here:  https://github.com/fmilburn3/RTC_F5529

 

Real credit for the work belongs to the original author.

I will sure follow your instructions while posting my next query on this forum so that i will get help as soon as possible

I modified the TI DriverLib example for the RTC_A on the F5529 to demonstrate the same thing as the Energia library for my own educational purposes and placed it here:  https://github.com/fmilburn3/MSP430F5529_driverlib_examples/blob/master/11A_RTC_A_calendar_mode

@Balwinder

You have double posted your question which is to be avoided.  Did you try the modified Energia version I posted above?  There are also TI CCS examples and the driverlib I posted above.
