How to read timer's current count

[premji]

Hi,

I am using nRF51822 and implemented timer-2 with 2 sec capture/compare interrupt rate. But if I want to read timer's current count before it generates interrupt or from out of ISR, how to read this count?? from which register I can get current counts of timer??

Your help will be appreciated.

Thanks and regards, Premji

@Premji: You can trigger a CAPTURE[n] task and the value of the counter will be stored in the CC[n] register. Have a look at chapter 18 in nRF51 Reference Manual.

NRF_TIMER2->TASKS_CAPTURE[0]; counter = NRF_TIMER2->CC[0];

Incorrect, it's

NRF_TIMER2->TASKS_CAPTURE[0] = 1;
counter = NRF_TIMER2->CC[0];
