For a good TouchSensor design, it is necessary to monitor touchpad readings, such as raw count value, baseline value and deviation of the count value, for calibration and debugging, and, most importantly, for evaluating the touch system performance in terms of Sensitivity, SNR (Signal-to-noise ratio) and Channel Coupling. OK, my bad, I got away without Arduino,h for a while - lucky me. Dial switch D3 respond to IO26 of FireBeetle-ESP32.
