https://devzone.nordicsemi.com/f/nordic-q-a/21669/adc-ain0---p0-0We have done a custom PCB believing that we could use P0.0 as analog input. Now we kind of found out that we cannot, and will change the PCB design. Given that we already have some of them manufactured, I have the need of making sure: Is there any wayen-USTelligent Community 13Fri, 28 Apr 2017 09:29:43 GMThttps://devzone.nordicsemi.com/thread/85091?ContentTypeID=1Fri, 28 Apr 2017 09:29:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f644ef4f-05f7-48c8-a624-4ef2a91da01bangel<p>Thanks Jorgen!</p> <p>Have a nice day!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/85090?ContentTypeID=1Fri, 28 Apr 2017 08:52:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:77596b02-f14a-4e0a-be0c-26021e4e78d3J&#248;rgen Holmefjord<p>P0.00 is ADC/LPCOMP <strong>reference</strong> input 0. It cannot be used as ADC input. You will have to change your layout to use one of the ADC inputs AIN0 - AIN7. Note that AIN0 and AIN1 is shared with the input pins for the 32.768 kHz crystal, and should be avoided if you use this in your application.</p> <p>Best regards,</p> <p>Jørgen</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/85089?ContentTypeID=1Fri, 28 Apr 2017 08:09:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7a9e2275-1455-4f74-8450-8ac8b897bff8angel<p>Hi Jorgen,</p> <p>Yes, I am using nRF51422</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/85088?ContentTypeID=1Wed, 26 Apr 2017 14:47:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ade22739-733c-4913-8949-a6a9fed773adJ&#248;rgen Holmefjord<p>Are you using nRF51422, as the tags indicate?</p><div style="clear:both;"></div>
