Hi, Ports 39 34 36 require pull up, and don't see any on your descriptions, is it because you're are using a specific rotary button with internal pull up?
Hi, no all pins GPIO have pull up and down integrated in the ESP32 execpt pins GPIO36, GPIO39, GPIO34, GPIO35. If the digitalpin (eg: 36 is configured to "high" and you turn de rotary button as the same time, you will probably burn the "pin". I just ask that to make a PCB for Nyglin, i don't have the code so i can't make it without any informations. Pin, ports my english is pretty far now so by the way sorry for that!
You're right, those are restricted pins mostly used for adc. I assume that if they're used here as a digital input, the pullups are on a rotary encoder module and that no bare encoder is used.
