TM4C123GH6PGE: RTC real time issue

Part Number: TM4C123GH6PGE
Other Parts Discussed in Thread: EK-TM4C1294XL

Hi team,

The customer would like to know is it possible to get the real time of the RTC from the M4(Year/month/day/hour/minute/second). If not, does the TI M4 have the capability to achieve count acquisition of real time?

After reviewing many documents, found that the RTC appears to be only available when the timer is in use, and it is not possible to set the base time first, and then get the real time. 

Could you help check this case? Thanks.

Best Regards,

Cherry

  • Hi Cherry, 

    TM4C123 does not support calendar mode. Only TM4C129 supports calendar mode. For TM4C129 you can refer to the calendar mode in C:\ti\TivaWare_C_Series-2.2.0.295\examples\boards\ek-tm4c1294xl\hibernate_calendar. Again, TM4C123 does not support calendar mode.
