TM4C129x: Low Power Mode support TI RTOS

Shreeranganath Gupta BBV

Hi All,

  We are using TM4C129x with tirtos_tivac_2_00_01_23 and wasn't able to get what low power modes of Tiva is being supported in TI RTOS for this version of TI RTOS.

   Any information on the same will be really helpful for us.


Thanks and regards,
Gupta

    Gupta,

    TI-RTOS does not provide any direct support for the low power modes on the TM4C devices, and there are no plans to add this.

    For your application you can add an Idle loop function that enacts some of these modes.  For example, to leverage CPU clock gating, you could add a function that has one instruction to invoke wait for interrupt while the CPU is idle, waiting for an interrupt:

    Void myWFI()
    {
        __asm(" wfi");
    }

    You could similarly add support for the other power saving modes, as appropriate for your application.

    Regards,
    Scott
