Configuring P0.01 as analog input on nrF52833https://devzone.nordicsemi.com/f/nordic-q-a/98294/configuring-p0-01-as-analog-input-on-nrf52833I have already configured four AI channels. See excerpts from the code below. /* Analog inputs */ #define HAL_ADC_BAT_VOLT_INPUT_PIN (NRF_SAADC_INPUT_AIN2) /* P0.04 */ #define HAL_ADC_BAT_CURRENT_INPUT_PIN (NRF_SAADC_INPUT_AIN3) /* P0.05 */ en-USTelligent Community 13Fri, 31 Mar 2023 09:42:02 GMTRE: Configuring P0.01 as analog input on nrF52833https://devzone.nordicsemi.com/thread/418530?ContentTypeID=1Fri, 31 Mar 2023 09:42:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f7bdbcf5-c9e9-457c-a569-5b7987f33797vidarm<p>I see, thanks for clarifying!

It is Analog Input when used as XL1, but a Generic I/O when used as P0.01.</p> <p>Please consider the other AINx pins as your fifth channel input.</p> <p>Hieu</p><div style="clear:both;"></div>
