https://devzone.nordicsemi.com/f/nordic-q-a/7361/trouble-reading-adc-on-nrf51422I am trying to perform a simple ADC measurement using polling rather than using an interrupt. I have looked at examples and read the ADC section in the reference manual, but I am still not having luck getting this to work.

There is an older one for SDK 6.0. But I need a newer(SDK 8.0), because I want to use it on the nRF51DK</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/26082?ContentTypeID=1Tue, 02 Jun 2015 00:36:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:93cdf2f1-76a8-4b3e-928f-d4b603aeda0ckalauffenburger<p>Thanks Nguyen!</p> <p>That did the trick.</p> <p>--ken</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/26081?ContentTypeID=1Mon, 01 Jun 2015 01:56:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:33459a92-e927-479e-b3ae-4637443cb710Nguyen Hoan Hoang<p>In your config you need to use ADC_CONFIG_INPSEL_AnalogInputOneThirdPrescaling for Analog pin as input. The ADC_CONFIG_INPSEL_SupplyOneThirdPrescaling is to use the VCC supply ad input.</p><div style="clear:both;"></div>
