Problem with GPIO pin 32

Postby erimads@gmail.com » Sun Sep 29, 2024 12:27 pm

I have this ESP32 dev. board but pin 32 don't work.
The compiler accept pinMode(32,OUTPUT) and digitalWrite(32,HIGH) but nothing comes out on the pin.
Can anyone help, I need to use all the output pins on the board.

Use a multimeter to ensure there is continuity between the edge gpio32 and the chip pin gpio32. Use a multimeter to ensure that the gpio value does not change (0->3V3) when you switch from low to high and back.
If those fail, then there is a hardware issue with the module.

I have tested on 2 different boards, and I have selected different boards in Arduino IDE same error in all cases.
What is the correct board to select i Arduino IDE ?
