gpio0 has an internal pullup. It is the programming strapping pin. It is a poor choice for anything other than the button that is ALWAYS attached to it on a dev board. That said, the code above works fine for me with a servo attached on 0.


Yes, the servo works on other ports. But please try if ...

I was experimenting and I found, servos work on other gpio, but not on GPIO0. Documents said that PWM output work on every gpio. They work but not on GPIO0. It is ESP32-PICI-MINI-02.
What is the reason, how to solve it?

There are very few information available about Esp32 Pico Mini. I want to use it as it is the smallest one I guess.
But developing software for this, encounters problems.
Arduino IDE 2.x ot 1.8x.
Selected board is ESP32 DEV (there is no this pico mini)
The problem is, that I am unable to control ...
