RTOS/CC1352R: RTC timer function hook definition

Clement Guillou

Part Number: CC1352R

Tool/software: TI-RTOS

Hi,

I'm using a function hook on the Channel 1 of the RTC to trigger events and I would like to make its definition at runtime instead of doing it in the realese.cfg file.

I have the following lines in the realsese.cfg :

var Timer = xdc.useModule('ti.sysbios.family.arm.cc26xx.Timer');
Timer.funcHookCH1 = "&RealTimeClock_InterruptHandler";

but i would rather "link" my function to the interrupt of the RTC at runtime, how can I do this ?

Thanks for the help,

Clement

Hi Clement,

The timer modules utilizes the RTC combined interrupt which means that you can not simply hook into the ISR in runtime.

You could try to point to a function rather then an actual function, in this case you could maybe populate the pointer in runtime.
I have not tested this so I can't say it will work for sure but you could try it out and see.

Hello M-W,

Is there an easy way to do it in C and if you have an example, it would be a great help.

Thanks,

Clement

Hi Clement,

After looking into it a bit more, there is no easy way of doing it. The simplest way I can come up with is implementing you own wrapper function that you hook into the Timer. Inside the wrapper function, you could call a run-time defined function.
