Is there a reason not to use it?</p><p>Also, I would suggest using the DelSig-ADC instead of the SAR ADC, as it should give you better stability in the results. (and IIRC it can do oversampling too)</p><p>If you want to use the PSoC even better: it has a digital filter block (DFB) that can be used to create a low-pass-filter. But I think its not directly supported by the RPiSoC API, you would need to use PSoC Creator to program it.</p><img src="https://community.element14.com/aggbug?PostID=18660&AppID=100&AppType=Weblog&ContentType=0" width="1" height="1">
