I am working on a 4x4 QMatrix with an AVR128DA28.
I run a project generated by Atmel START with example code and monitor the status of each pad with a data visualizer.
There is no problem so far under careful use.
I put my hand on the entire pad, assuming the device is in pocket.
The problem arises here.
Some buttons do not return to OFF even after releasing my hand.
The PTC (Peripheral Touch Controller) is a black box and I don't know what's going on inside.
Does anyone know how to adjust or restore?
Normal (touching button 0)
The data after I release my hand stays above the threshold and remains perceived as "touching".
