Frequency counter on NRF52805

Hi, I want to use an NRF52805 with a voltage to frequency detector. If I understand the datasheet, there is one timer/counter and RTC on that chip. Is it possible to set the RTC as the timing gate, and  use the T/C as an input pulse counter through the event system? I'm planning to use a single clock source (prob. 32MHz) and synthesize the LF clock required for the RTC from it.

I will be happy to know if this is a good way to go before fully adopting the hardware.

Cheers,

    It seems like you're mixing the nRFConnect SDK and the nRF5 SDK code structures quite a bit in your example project, which is likely what's causing trouble for you. As the nRFConnect SDK is RTOS based there will be quite a few changes from the old SDK. If you're new to the nRFConnect SDK I would suggest checking out this tutorial series to get familiar if that's the case.

    Best regards,
