Recently we found a problem in our HMI, when interference(EMI) is injected upon HMI electrodes there comes a situaion when one or more electrodes are being permanently detected as pressed untill new startup.</P><P>After detailed analysis we found out that when inetreference is injected then there comes a situation when Baseline signal adopts itself to a lesser value than Instant signal and its always detecting as touch because Instant delta remains higher than our electrode threshold and baseline will not adopt itself untill release has been detetcted.</P><P>Anyone else faced the same issue? or any leads how we can fix it?</P><P>We are using Kinetis K10 uc with Processor expert having 8 electrodes.&nbsp;</P></BODY></HTML> Thu, 08 Aug 2019 07:45:18 GMT https://community.nxp.com/t5/Processor-Expert-Software/Wrong-Touch-Detection/m-p/964314#M4380 taimurwajad123 2019-08-08T07:45:18Z Re: Wrong Touch Detection https://community.nxp.com/t5/Processor-Expert-Software/Wrong-Touch-Detection/m-p/964315#M4381 <HTML><HEAD></HEAD><BODY><P>Hi</P><P>Are you setting the autocalibration function? also, there is a&nbsp;<SPAN style="color: #51626f; background-color: #ffffff;">manual calibration or hardware recalibration ( I do not remember which one reset the baseline)</SPAN>, I recommend you do the calibration after some time.</P><P>Also, you can change the N samples to get better results</P><P>regards</P><P></P><P>Vicente Gomez</P></BODY></HTML> Mon, 12 Aug 2019 17:25:52 GMT https://community.nxp.com/t5/Processor-Expert-Software/Wrong-Touch-Detection/m-p/964315#M4381 vicentegomez 2019-08-12T17:25:52Z
