Hi:

when i use sdk, i want to use Timer module,so my code like this:

#include <ti/sysbios/hal/Timer.h>

int main(void)

{

Timer_Params timerParams;

Timer_Handle myTimer;

Error_Block eb;

Error_init(&eb);

Timer_Params_init(&timerParams);

timerParams.period = 1;

timerParams.periodType = Timer_PeriodType_MICROSECS;

timerParams.arg = 1;

myTimer = Timer_create(Timer_ANY, myIsr, &timerParams, &eb);

if (myTimer == NULL)

{

BIOS_exit(0);

}

BIOS_start();

}

but why it shows Timer_create() function "undefined symbol" error?

And i have another problem:

when i use Clock module,it doesn't work too,myHandler1() will never be executed:

void myHandler1(xdc_UArg arg1)

{

//the code will never reach here!!!

}

int main(void)

{

Clock_Params clockParams;

Clock_Handle myClock;

Error_Block eb;

Error_init(&eb);

Clock_Params_init(&clockParams);

clockParams.period = 1000;

clockParams.startFlag = TRUE;

clockParams.instance->name = "okok";

myClock = Clock_create(myHandler1, 1000, &clockParams, &eb);

if (myClock == NULL)

{

BIOS_exit(0);

}

BIOS_start(); /* does not return */

return 0;

}

Hi,

Can you create a task, then start the timer and in the task function, can you try creating timer?

You could refer to thread, https://e2e.ti.com/support/processors/f/791/t/890464, for task creation.

Rgds,

Brijesh

Hi Brijesh:

The problem has be resolved after i add "var ti_sysbios_hal_Timer = xdc.useModule('ti.sysbios.hal.Timer');" in *.cfg file.

Thanks!!
