I use 9.1k pullup resistor connected to 3.3 VDC for the pins 34,35,36 and 39. No change.

Here the code (diagnostic program for the smart hand controller in project Onstep - https://onstep.groups.io/g/main/wiki/7152): /// A diagnostic exerciser and dumb handbox emulator for the OnStep Project ESP32-based Smart Hand Controller (SHC) // // Author: Dave Schwartz // // Revision history: // 1...

I build a circuit on a breadboard using a ESP-WROOM-32 (equivalent to a nodemcu 32S) and connected pins 34,35,36,39 to a momentary button with a 3.3k pullup resistor. A diagnose program is report that all the buttons has been pushed down at the same moment while a only click on one of then. Anybody ...
