Hi,

The following code is works well in debug remote mode.

But When I plugged out the usb port of launchpad(standalone mode) It does not working at event_pend().

I used default environment and example(sensor node network configuration) and only check the timer.

Thanks.

Void tickFxn(UArg arg0)
{
// Timer_getFreq(timer1, freq);
static UInt16 toggle = 0;
toggle++;

if((toggle % 10) == 0){
PIN_setOutputValue(ledPinHandle, Board_LED3,!PIN_getOutputValue(Board_LED3));

     /* Save latest value */
     latestAdcValue = (uint16_t)rand();
     //latestAdcValue = toggle;

     /* Post event */
     Event_post(nodeEventHandle, NODE_EVENT_NEW_ADC_VALUE);
//  System_printf("myIsr arg = %d\n", (Int)arg0);
}
}

static void nodeTaskFunction(UArg arg0, UArg arg1)
{
    /* Open LED pins */
    ledPinHandle = PIN_open(&ledPinState, pinTable);
    if(!ledPinHandle) {
        System_abort("Error initializing board 3.3V domain pins\n");
    }
#if 1

Timer_Params timerParams;
Timer_Handle myTimer;
Error_Block eb;

Error_init(&eb);

#else
    /* Start the SCE ADC task with 1s sample period and reacting to change in ADC value.
     * A change mask of 0xFF0 means that changes in the lower 4 bits does not trigger a wakeup.*/
    SceAdc_init(0x00010000, 0xFF0);
    SceAdc_registerAdcCallback(adcCallback);
    SceAdc_start();

Hi,

what you describe sounds like that the timer doesn't work in standby. Standby is only enabled when running without the debugger. I wonder how the Timer module is implemented for the CC13xx and if it correctly sets power constraints. For your application, I recommend using the Clock module. The API is very similar.

I recommend to let XDC generate the boilerplate init code for you. Just copy the following code into your .cfg file or use the GUI to setup an additional clock instance:

/* ================ Application Specific Instances ================ */
var clock0Params = new Clock.Params();
clock0Params.instance.name = " myTimer";
clock0Params.period = 100000;
clock0Params.startFlag = true;
Program.global.periodicClock = Clock.create("&tickFxn(", 100000, clock0Params);

Then you can drop all your Timer-related setup code above and just need to provide the function tickFxn (ist must not be static). From your application code, you can access myTimer by just declaring it:

// myTimer is defined and initialized in an externally generated source file
extern const Clock_Handle myTimer;

Hi! Richard,

Thank you very much!
I accepted the your suggestion.
It is easy and simple.

Best regards
TS Yoon.
