Idle function in pinInterrupt with CC2650DK

Thomas Kot

When using the example code of pinInterrupt in the cc2650DK kit, it works well. CCS v6.1 is used.

When I add an idle function using the GUI, it is supposed to call the idle function when the keys are not pressed, but it does work.

A breakpoint is set onto a the idle function, it has never been called.

the setup is as follows after using the GUI with cfg file:

in the pinInterrupt.cfg, the following code is added to the bottom of the cfg file.

Idle.idleFxns[0] = "&idle_fx";

in the pinInterrupt.c , the following function is added

void idle_fx(void)

{

uint32_t currVal = 0;

currVal = PIN_getPortOutputValue(ledPinHandle);

PIN_setPortOutputValue(ledPinHandle, ~currVal);

}

Please let me know if I have missed anything to set it right.

Regards,

Thomas

a typo: it should be "it does not work"
the interrupt is still functioning. when key is pressed, the LED switches on and off; but the function of idle_fx has never been called.

Thomas,

Even if you add an idle function it will probably not be called from the task scheduler unless the Task scheduler has enabled the Idle task.
Our BLE stack example config file have this added:

/* Enable idle task (default). */
Task.enableIdleTask = true;

Can you try this and see if that helps?

Svend,

Thanks. It works.
Does it have a user guide for setting up the cfg script?

Regards,
Thomas

Thomas,

The TI RTOS User's guide (http://www.ti.com/lit/ug/spruhd4i/spruhd4i.pdf) covers many of these parameters. In CCS modules can be configured graphically but our examples has set up the scripts manually instead.

Regards,

Svend
