https://devzone.nordicsemi.com/f/nordic-q-a/70063/failed-to-read-analog-valueHello I am using sdk v17.0 and nRF52DK. I&#39;m going to simply read the analog sensor MICS-5524 (gas sensor). And to do this, we used the SAADC example code and connected it to the 5V, Gnd, and A0 pins. However, it does not read any value from the sensoren-USTelligent Community 13Tue, 05 Jan 2021 02:16:29 GMThttps://devzone.nordicsemi.com/thread/287367?ContentTypeID=1Tue, 05 Jan 2021 02:16:29 GMT137ad170-7792-4731-bb38-c0d22fbe4515:929159b7-118f-4cd5-86b1-7a2027fc0bd5schosdas<p>Ah.. The DK board says A0 is p0.03, but you are right. It works well after changing the code to Ain1.</p> <p><br />Thank you!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/287198?ContentTypeID=1Mon, 04 Jan 2021 11:18:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6e40b4ba-ac12-4d41-9c51-a1a11919b478Charlie<p>Hi,</p> <p>The SAADC example&nbsp;<span>actually&nbsp;</span>uses AIN0(P0.02). You can find its position from the DK schemtic in the hardware design package.</p> <p>Best regard,</p> <p>Charlie</p><div style="clear:both;"></div>
