Yes, I've been having trouble calibrating the ADC on the ESP32. I'm trying to get the ADC on the ESP32 to mimic the ADC on the atmega328p (MCU of the Arduino Uno) for a project I made for the atmega328p that I'd like to get working on the ESP32. The ADC on the atmega328p uses the input voltage as the reference voltage by default which is usually 5V and I'd like to set a pin on the ESP32 that is receiving 5V to be the reference pin. I tried to do so using the analogSetVRefPin() but it doesn't exist for my board (image below).I notice that you're using “ESP32 Dev Module” not the FireBeelte. Does that board work with the FireBeetle? If so, could you provide the url for the board manager?

Follow up: I can't seem to even find any indication of what the reference voltage is for the FireBeetle board. Any information regarding this or the original post would be greatly appreciated.

SOLVED: I was experiencing the problem linked below

Yes, I have python installed I use it for other projects. Why does python have anything to do with the FireBeetle ESP32? I'm not using micropython with it.
