https://devzone.nordicsemi.com/f/nordic-q-a/34778/adc-device-driver-won-t-compile-in-sdk-15Hey guys, I&#39;m trying to use the ADC device driver in SDK 15 (saadc seems to always use an event handler and thus require interrupts, right?). It won&#39;t compile since there are numerous defines that are not defined somehow. So, I have defined NRFX_ADC_ENABLEDen-USTelligent Community 13Mon, 28 May 2018 09:31:18 GMThttps://devzone.nordicsemi.com/thread/133610?ContentTypeID=1Mon, 28 May 2018 09:31:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:598563d0-55bc-44a0-b415-08d0ed624233jev<p>Ah, of course.

You get the errors because the registers are not defined in the <a href="https://github.com/NordicSemiconductor/nrfx/blob/master/mdk/nrf52.h">nrf52.h</a> and&nbsp;<a href="https://github.com/NordicSemiconductor/nrfx/blob/master/mdk/nrf52_bitfields.h">nrf52_bitfields.h</a> header files.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
