RTOS/CC1310: PWM Synchronization

Hi,

I have tested it using the PWM example from the SDK on a CC1310 launchpad. You must call TimerSynchronize() after PWM_start(), not before. PWM_start()/stop() enable/disable the timer and hence, the sync information is lost.

void *mainThread(void *arg0)
{
    PWM_Handle pwm1 = NULL;
    PWM_Handle pwm2 = NULL;
    PWM_Params params;

    /* Call driver init functions. */
    PWM_init();

    PWM_Params_init(&params);
    params.dutyUnits = PWM_DUTY_US;
    params.dutyValue = 1500;
    params.periodUnits = PWM_PERIOD_US;
    params.periodValue = 3000;

    pwm1 = PWM_open(Board_PWM0, &params);
    assert(pwm1 != NULL);

    pwm2 = PWM_open(Board_PWM1, &params);
    assert(pwm1 != NULL);

    PWM_start(pwm1);
    usleep(371);
    PWM_start(pwm2);

    TimerSynchronize(GPT0_BASE, TIMER_0A_SYNC | TIMER_0B_SYNC);

    PWM_setDuty(pwm1, 1000);
    usleep(487);
    PWM_setDuty(pwm2, 500);

    for (;;);

}
