SIMPLELINK-CC3220-SDK: Wake from Timer in LPDS

Part Number: SIMPLELINK-CC3220-SDK


Hi,

I am using LPDS in power_management sdk example and I am able to wake from gpio, but

how do I wake from the timer?

PowerCC32XX_ConfigV1 has settings for: .enableGPIOWakeupLPDS = true

but nothing for SLW_CLOCK wake.

Thanks, Tom

    Hi Tom,

    I believe calling the sleep (X) function causes the device to wake up after the specified X time. See snippet from power management example below

    Hi Charles,

    Yes, the sleep function does work if you want to wake from just time, but I want to awake from GPIO or Time. So, if in the sleep function, the gpio state will be ignored.
    Looks like the LPDS mode, not compatible with WDT and GPIO, Timer wakeup issues, is not ready for prime time...was seamless in gen 1.
    Maybe more examples or sdk update will fix??

    Thanks, Tom
