Hi. I have the same issue. I want to change old chip to STM32 blue pill board on floor fan. I make something with analogRead. And it`s sometimes work. But I`m a newbie in programming and try to find better way.
In fact in was spiral connected to chip with 1K resistor.
Maybe someone have the example for this type of touch sensor?
Mod: new thread, link to old thread.
