https://devzone.nordicsemi.com/f/nordic-q-a/17807/why-saadc-values-are-changed-on-different-compare-timeHello! I tried to check the saadc value by using sample that is provided nordic homepage, and I just found that the saadc values changed when I changed the compare time. I&#39;d like to check the saadc value more frequently. I think, the input voltageen-USTelligent Community 13Fri, 18 Nov 2016 08:56:41 GMThttps://devzone.nordicsemi.com/thread/68640?ContentTypeID=1Fri, 18 Nov 2016 08:56:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6dc481a2-0714-47f7-a0c7-c4ade5f67c86J&#248;rgen Holmefjord<p>I checked middle value as well now, still get same value for 2 ms as 400 ms.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/68641?ContentTypeID=1Fri, 18 Nov 2016 08:46:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:101963fb-f4f7-4c50-a05c-9c05a4014d98wan<p>thank for advice. I put a sensor to pin 0. and detected voltage is almost same.( I&#39;m not remember the voltage value, unfortunately.) could you check middle value to pin 0? not a edge value like VDD or GND</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/68639?ContentTypeID=1Thu, 17 Nov 2016 15:14:29 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3221a414-cf7b-459d-bd1d-337bfb52bcb8J&#248;rgen Holmefjord<p>Hi,</p> <p>Did you connect analog input pin 0 (P0.02 GPIO) to anything? I see the same difference you do if I leave the pin unconnected, but if I connect it to VDD or GND I get correct values for both 400 ms and 2 ms.</p> <p>Best regards,</p> <p>Jørgen</p><div style="clear:both;"></div>
