Simple timer as counter

Hello Oskar,

If you would like to capture the value of a TIMER instance you could use the nrfx_timer_capture or nrfx_timer_capture_get functions to do so.
Make sure you are not using TIMER0 or RTC0 since these peripherals are blocked by the SoftDevice (if present).

Best regards,
Karl

Hi,

Thanks a lot for the suggestion but it seems that you are using the RTC and the 32kHz clock while I am trying to use the 32MHz clock.

My application could perhaps do with the 32 kHz instead, but I am using an NRF52820 which only has two RTCs and both of these are already in use unfortunately

Hi,

You can refer to my github to get the timer tick.

uint32_t counter_get(void)
{
    return(nrf_drv_rtc_counter_get(&m_rtc));
}
