count task dont work

[michalmmz]

Hello,

After i disable SD i try to count ticks on TIMER1 from RTC1 via PPI. Timer1 is configured property but TASK_COUNT don't increment cc. I see that event TICK on RTC1 is generating. Even if i call NRF_TIMER1->TASK_COUNT=1; cc is not changing. Before i make the same scenario without SD and was work property.

any ideas?

The COUNT task does not increment CC register. It increments the internal counter register. Quote from spec

"In counter mode, the TIMER's internal Counter register is incremented by one each time the COUNT task is triggered"

CC registers are software rewritable compare boundaries

function nrf_drv_timer_capture(&timer1, NRF_TIMER_CC_CHANNEL0) suggested to me that this value should be in the CC. Thank you for the quick reply.
