https://devzone.nordicsemi.com/f/nordic-q-a/63654/nrf52832-adc-differential-mode-configuration-positive-and-negativeHi, we are using nRF52832 SAADC in differential mode. We have two channels connected. Inputs are now configured as differential-N and differential-P (PSELP and PSELN). how to define ADC pin as PSELP(p0.2) and PSELN(P0.3) with their pin number? ien-USTelligent Community 13Mon, 13 Jul 2020 09:08:58 GMThttps://devzone.nordicsemi.com/thread/259640?ContentTypeID=1Mon, 13 Jul 2020 09:08:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:735db387-b331-4444-8903-466c70a51449haakonsh<p>In <a title="nrfx_saadc_channel_init" href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.0/group__nrfx__saadc.html?cp=7_1_6_8_0_30_1_15#gab74892a83a2f842436fac5f1462eca6a">nrfx_saadc_channel_init</a>() you pass&nbsp;a&nbsp;<a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.0/structnrf__saadc__channel__config__t.html">nrf_saadc_channel_config_t</a>.
