https://devzone.nordicsemi.com/f/nordic-q-a/37412/how-to-know-gpio-and-adc-ainx-mappingHi Sir How to config channel and AINx to specific gpio for SAADC ? For example, if I want read adc voltage from NRF_GPIO_PIN_MAP(0,5), how to set the channel and AIN ? Thanks. nrf_saadc_channel_config_t channel_config = NRF_DRV_SAADC_DEFAULT_CHANNEL_CONFIG_SEen-USTelligent Community 13Mon, 13 Aug 2018 09:33:20 GMThttps://devzone.nordicsemi.com/thread/143892?ContentTypeID=1Mon, 13 Aug 2018 09:33:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:506c7ee4-bde0-4a93-a914-342fea07778eJustin_Yeh<p>Thanks.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/143875?ContentTypeID=1Mon, 13 Aug 2018 08:51:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b4c995cb-c88c-4d66-bf24-ca68e9108348Turbo J<p>Assumung you use the NRF52832, the analog inputs are documented in the PS (product specification) chapter 4 &quot;Pin assignments&quot;: P0.05 is mapped to AIN2.</p><div style="clear:both;"></div>
