https://devzone.nordicsemi.com/f/nordic-q-a/54191/saadc-keeps-printing-same-value-0-and-previous-valueHi Devzone I tried to use saadc with 4channels. when I use this without fpu_fft, It prints correct value well. But, when I insert the fpu_fft and run it, after a while, saadc prints 0 and fixed previous value. I think the problem is busy CPU.en-USTelligent Community 13Thu, 14 Nov 2019 12:01:39 GMThttps://devzone.nordicsemi.com/thread/220055?ContentTypeID=1Thu, 14 Nov 2019 12:01:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:cc2097f5-672c-4c5b-8f85-fd7864cdbb18zester926<p>Hi haakonsh!</p> <p>Thank you! You are right. The data was being corrupted by other function. Because I read the data and store it at same place. Now, I solved it.</p> <p></p> <p>Thank you</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/219451?ContentTypeID=1Mon, 11 Nov 2019 12:05:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:97f5ef7a-5156-4183-a204-213025c13506haakonsh<p>It&#39;s most likely not the SAADC that outputs zero value, but rather how the samples are processed or printed that corrupts the data.&nbsp;<br /><br />You need to verify your data after each step where you&#39;ve processed it, in order to find out where and how the data gets corrupted.&nbsp;</p><div style="clear:both;"></div>
