CC2640R2F: RTC demo for CC2640R2F

Part Number: CC2640R2F

Hi Team,

        My customers would like to realize the function that CC2640R2F can do a some operation in 12:00 pm(or other time) every day. For example, at 13:00am on Monday,  CC2640R2F read the temperature.  At 14:00am on Saturday, CC2640R2F drive the motor.

       I think the RTC function can do that. Do we have this RTC demo or other resource to be provide for customers?

Thanks!

    Correct, but the TI-RTOS system tick use the AON RTC as its clock source, therefore that could be an issue. Worst case scenario we can use another timer.

    I'm not aware of any demo like this one, but let me see what I can find out.  When do you need it??

      Thanks,

  • Hi David,

            I think it will better we can get it by the end of Feb. 2018!

    Thanks for your great support!

    One more question, as you said, Worst case scenario we can use another timer. What is the meaning of "another timer"?

  • Great, so let me work on this and I'll try to have it ready by next week.

    I meant using a General Purpose Timer to keep track of the time.

       Best regards,

  • Hi David,

            Awesome! Thanks for your great support!

    If using a General Purpose Timer to keep track of the time, it will be high power consumption because it need to wake up M3 per second to update the time.

     Best regards,

  • Hi Eggsy,

    What is the power budget? I just want to make sure that I know this while I'm developing the example code.

    Thanks,

  • Hi David,

           I think Standby average current need to < 10ua.
