https://devzone.nordicsemi.com/f/nordic-q-a/12807/reading-gpio-analog-input-on-nrf52I am trying to read an analog value on the GPIO port into my application. Looking through the examples, there aren&#39;t any that help solve this problem as the ADC example is only for the NRF51.

And the nrf_gpio_port_read() does something completely different and unrelated and doesn&#39;t take a pin number as parameter.</p> <p>Reading analog values is an entirely different process which requires setting up the ADC, asking for a value, waiting for conversion etc. A 10 second grep in the SDK for &#39;saadc&#39; shows the ble_app_proximity example uses ADC and has both nRF51 and nRF52 code in it. So perhaps you&#39;d be better off taking a look at that.</p><div style="clear:both;"></div>
