Timer in Counter Mode is not counting via PPI?

I get a lot of compile errors when trying to compile your example. I had to remove UART from the application as the vector variable is not supported on my system. However, I get a warning that nrf_drv_clock_init and nrf_drv_clock_hfclk_request is implicitly declared, and you are missing inclusion of header file nrf_drv_clock.h. Could it be that your clock is not running?

I have tested my code on my own PCB. The Timer 4 compare wasn't triggerred. In my application, soft device was loaded but not initialized.

I tested your code on nRF52-DK (PCA10040 board), and I'm getting interrupt on the compare event on TIMER4. Have you tested your code on a DK? I only changed the SPI pins to 27-29, to avoid crash with the crystal on the DK, and call ccd_init() once and ccd_run() in a loop in main().

Is the SPI communication working as expected? Are you using the nRF52 Preview DK (PCA10036 board), as your tags indicate? If you are a nRF52-DK/PDK, have you removed the crystal and connected the P0.00 and P0.01 pins to the pin header?
