Triggering a task when a TIMER event

[sd]

I'm looking at the led.c example in the heart rate monitor example. What this shows is how to tie a TIMER event to toggling an LED. I understand most of the mechanism there. The novice that I am, it is not clear to me, however, how I'd connect that event to trigger a custom task (in my case, reading data from a TWI peripheral). Any code examples, documentation, or sample code out there?

Thanks!

Hi

To trigger peripheral tasks with timer event you use PPI channels. The gpiote_example for the nRF51822 development kit (with the nRF6310 motherboard) shows how this is done. PPI documentation is found in the nRF51 reference manual.

To clean things up, I'd be happy if you could evaluate the answer you have received and accept it if you feel it's sufficient. If not, it might be useful to expand your question a little and provide further information.
