You can do capacitive touch with RP2040 just fine. Turn on, turn off, measure time. Plus I don't like modules as they seem pointless complexity when I just want

- _Microft 2y agoI also did not understand this complaint. On a Pico, any GPIO can be used for touch (using PIO of course). Example with 23 touch buttons if I counted that correctly: https://github.com/todbot/picotouch https://github.com/todbot/picotouch
- peteforde 2y agoThanks for this! I am happy to have been wrong about the touch stuff, because I'm learning a lot.
- _Microft 2y agoThe same user has also got a board with touch sliders, consisting of inversely tapering touch areas that allow to compute the touch position along the axis (same for rotary sliders that use three of these in a circle configuration). https://github.com/todbot/picoslidertoy https://github.com/todbot/picoslidertoy
