SAADC Value is not changing as it shouldhttps://devzone.nordicsemi.com/f/nordic-q-a/83908/saadc-value-is-not-changing-as-it-shouldHello, On a custom board, using the NRF52832, we want to know the value of a potentiometer. This value is send via a signal on the AIN5 pin of the NRF52. So, I tried to set up a code to read the value via the saadc module, but it seems it doesn&#39;t worken-USTelligent Community 13Fri, 21 Jan 2022 14:01:14 GMTRE: SAADC Value is not changing as it shouldhttps://devzone.nordicsemi.com/thread/348953?ContentTypeID=1Fri, 21 Jan 2022 14:01:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c324a1bf-ccdf-488e-97c4-46610f354101haakonsh<p>Glad to you sorted it out! :)&nbsp;</p><div style="clear:both;"></div>RE: SAADC Value is not changing as it shouldhttps://devzone.nordicsemi.com/thread/348939?ContentTypeID=1Fri, 21 Jan 2022 13:23:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:dd9ab21b-0edf-4f5e-928d-6cdf1a152946Christos.Bou<p>Thank you, you were right, the hardware information of our team was not correct !</p><div style="clear:both;"></div>RE: SAADC Value is not changing as it shouldhttps://devzone.nordicsemi.com/thread/348933?ContentTypeID=1Fri, 21 Jan 2022 12:54:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:40c8917e-ecdc-46ec-a8e9-6acfcf09e2b2Christos.Bou<p>Ok, I&#39;ll re-check if this is connected in the hardware.</p><div style="clear:both;"></div>RE: SAADC Value is not changing as it shouldhttps://devzone.nordicsemi.com/thread/348927?ContentTypeID=1Fri, 21 Jan 2022 12:47:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:feaed154-de54-44b1-8ac8-e5aef0ac7136haakonsh[quote user="Christos.Bou"]How do you know that the AIN5 seems to be floating ?[/quote] <p>I just recognized the sample values and their variance. They are typical for the default single-ended settings and floating input pin.&nbsp;<br /><br /><br /></p> [quote user="Christos.Bou"]I mean that in the Debug Terminal, it shows 3 values, then wait for a delay and show after 3 other values.

I think we call it defered logging in the API/docs.<br /><br />-Edit: You can turn this feature on/off.</p><div style="clear:both;"></div>RE: SAADC Value is not changing as it shouldhttps://devzone.nordicsemi.com/thread/348924?ContentTypeID=1Fri, 21 Jan 2022 12:40:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:05f3c0fe-682d-48ba-82c9-8d7c534a6464Christos.Bou<p>How do you know that the AIN5 seems to be floating ? Actually, we are trying to re-build an old code that was made in js for the same hardware and in this code it was using AIN5, so I&#39;m pretty sure that this pin is connected to it.<br /><br /></p> <p>I mean that in the Debug Terminal, it shows 3 values, then wait for a delay and show after 3 other values.

Most likely you&#39;re connected the potentiometer to the wrong pin.&nbsp;<br /><br /><br /></p> [quote user=""]Another issue that I had, is that the adc value are showing 3 by 3 with a delay but I&#39;ve not implemented a delay, so I don&#39;t know why...[/quote] <p>I don&#39;t understand, what do you mean by &quot;showing 3 by 3&quot; and &quot;with a delay&quot;?&nbsp;</p><div style="clear:both;"></div>
