Did you create your own project, or did you use the one I provided? If you created your own project, you need to add the path to nrf_drv_adc.h header file to your project. You did copy the entire adc directory…

I have made an example, but I have not tested it (I don't have a IoT setup to test on), but I checked that the example compiles and runs.

You need to copy the ADC driver and HAL from SDK 11.0.0 into your nRF51 IoT SDK directory:

Copy the directory components\drivers_nrf\adc from SDK 11.0.0 to Nordic\nrf51\components\drivers_nrf in nRF51 IoT SDK v0.8.0.

Copy the files nrf_adc.c and nrf_adc.h from components\drivers_nrf\hal\ in SDK 11.0.0 into directory Nordic\nrf51\components\drivers_nrf\hal in nRF51 IoT SDK v0.8.0.

Best regards,

Jørgen
