SIMPLELINK-CC13X2-26X2-SDK: HWI or SWI on RAT_GPO0 or RAT_GPO1 edges

Thanks Sid! I did not see the callback option.

I only saw capture/compare and assumed we could only wiggle GPIO. 
I'll give this a try, thank you. 

Thanks again Sid. 

So I'm calling this for 100 us after I schedule an RX or TX using RF_runCmd. 
My callback is firing constantly with RF_EventError. On the scope, the timing is off, which agrees with RF_EventError

I don't suppose there is an example of this somewhere. 

Here's the invocation. My master sync's on Tx start time, and slaves sync on Rx rxTime from the packet as in the rfSynchronizedPacket example. This part has been working well. I included it for context because I just add 100 uS to startTime. 

    if (isMaster()) {

        rf_ctx.RF_cmdPropTx->startTime += RF_convertUsToRatTicks(slotTimeUs);

        rf_ctx.RF_cmdPropRx->startTime = rf_ctx.RF_cmdPropTx->startTime;

    } else {

        rf_ctx.RF_cmdPropRx->startTime += RF_convertUsToRatTicks(slotTimeUs);

        rf_ctx.RF_cmdPropTx->startTime = rf_ctx.RF_cmdPropRx->startTime;

    }

    scheduleTask(rf_ctx.RF_cmdPropRx->startTime + RF_convertUsToRatTicks(100));

Here's the scheduler

static void scheduleTask(uint32_t timeout) {

    RF_RatConfigOutput ioCfg;

    RF_RatConfigOutput_init(&ioCfg);

    RF_RatConfigCompare channelCfg;

    RF_RatConfigCompare_init(&channelCfg);

    channelCfg.callback = &scheduleTaskCb;

    channelCfg.timeout = timeout;

    RF_ratCompare(rfHandle,&channelCfg, &ioCfg);

}

Here's the callback, just toggling a GPIO and posting a semaphore (which never happens) 

static void scheduleTaskCb(RF_Handle h, RF_RatHandle rh, RF_EventMask e, uint32_t compareCaptureTime) {

    switch(e) {

        case RF_EventRatCh:

            GPIO_toggle(CONFIG_GPIO_TP1);

            Semaphore_post(rfSem);

            GPIO_toggle(CONFIG_GPIO_TP1);

            break;

        case RF_EventError:

//            printf("RF_EventError\n");

            break;

    }

}
