Hi,
I use TP223 based touch sensors like this:
The sensors are installed with the pins facing down. The top must then lie against the cover. This works best and safest if you cut off the protruding pin pieces on the top and carefully file them away. The pins are still soldered in then. The sensor surface then rests on the cover over a large area and can detect through the cover.
Software:
I use the latest tinypilot image for the Raspberry Pi (with a light modified hat.conf for the jlx 12864 lcd) and a modified motor.ino from Timo (pypilot/arduino/motor at master · McNugget6750/pypilot · GitHub). I modified it a little. Using other Pins for the IBT-2 bridge and change the pwm-frequncy so that the motor sound´s not like a howling dog and I don´t use a status tft like Timo cause all needed infos are shown in the plugin or on the lcd.
I´m trying to write a little guide in the next days. When ready I´ll think that this makes thinks clearer.
Best regards
Andreas
