That did the trick. Thank you. What is the difference between the nrf and nrfx libraries? All the examples that I've seen reference the nrf drivers.

Hi,

The nrfx_saadc driver does not support passing NULL as the argument to the config parameter to the init function. If you build in debug config (with symbol DEBUG_NRF defined), you will get an assert from this code.

Try this:

nrfx_saadc_config_t saadc_config = NRFX_SAADC_DEFAULT_CONFIG;
uint32_t err = nrfx_saadc_init(&saadc_config, saadc_handler);
APP_ERROR_CHECK(err);

Best regards,
Jørgen
