CC1310 nortos time demo

要怎么设置才可以让定时器一直重复跑？

    GPTimerCC26XX_Params params;
    params.width          = GPT_CONFIG_32BIT;
    params.mode           = GPT_MODE_ONESHOT_UP;
    params.debugStallMode = GPTimerCC26XX_DEBUG_STALL_OFF;
    hTimer = GPTimerCC26XX_open(Board_GPTIMER0A, &params);
    if(hTimer == NULL)
    {
        while(1);
    }
 
    rxTimeoutVal = (SysCtrlClockGet()*3UL)/10UL - 1UL;
    GPTimerCC26XX_setLoadValue(hTimer, rxTimeoutVal);
    GPTimerCC26XX_registerInterrupt(hTimer, rxTimeoutCb, GPT_INT_TIMEOUT);
 GPTimerCC26XX_start(hTimer);

void rxTimeoutCb(GPTimerCC26XX_Handle handle,
                 GPTimerCC26XX_IntMask interruptMask)
{
    GPTimerCC26XX_setLoadValue(hTimer, rxTimeoutVal);
 PIN_setOutputValue(pinHandle, Board_PIN_LED2,!PIN_getOutputValue(Board_PIN_LED2));
 
 //GPTimerCC26XX_start(hTimer);
}

请问要怎么样设置才能使定时器重复进入中断？

必须要在回调函数里面每次去 start吗?

你要用GPTimer的什么模式？下面是我配置的下降沿中断检测的代码，每次检测到下降沿，就打印感叹号：
