GPIO not working on esp32 pico D4

Postby dominik » Thu Jul 05, 2018 7:45 pm

I bought two esp32 pico D4 boards from https://www.elektor.com/esp32-pico-kit- ... m_store=de

Although I could program the board via platform.io and I get nice output on the serial console all GPIO pins seem to be broken. Regardless of what i write with digitalWrite I always have 0V on the pin. And if I configure the pin to INPUT_PULLUP I always get a 1 from digitalRead even if I connect to gnd.

The same code works perfectly fine on an other esp32 dev board.

Is there something special with the pico D4?

My esp32 pico d4 board work fine using Arduino ide and esp-idf, but the logic is inverse, so I have to set the pin low to turn on the internal led.

It's resolved. It was a stupid bug on my side. I used the pin no instead of the GPIO no to address the gpio pins. :x
