LAUNCHXL-CC1312R1: SCS & Timer_open

David Jones

I have setup and I am using timer1 in Sensor Controller Studio, I have also setup timer0 in CCS code, but I cant open timer0, fails on Timer_open(CONFIG_TIMER_0, &timparams); below

Timer_Params_init(&timparams);
timparams.period = 1000000;
timparams.periodUnits = Timer_PERIOD_US;
timparams.timerMode = Timer_CONTINUOUS_CALLBACK;
timparams.timerCallback = timerCallback;

timer0 = Timer_open(CONFIG_TIMER_0, &timparams);
if (timer0 == NULL) {
    /* Failed to initialized timer */
    while (1) {}
}

Regards

I am not able to re-create the problem. I took the timerled example (using CONFIG_TIMER_0) from the latest SDK and added some SC code using Timer 1:

// Generate timer event after 200 us
timer1Start(TIMER1_MODE_SINGLE, 4800, 0);
gpioSetOutput(AUXIO_O_LED);

// Wait for the timeout
timer1Wait();
gpioClearOutput(AUXIO_O_LED);

// Schedule the next execution
fwScheduleTask(1);

I did not have any problems doing:

 timer0 = Timer_open(CONFIG_TIMER_0, &params);
