Existential doubt about ESP32-ADC2 pins

#1

Hello guys,

I have an existential question about ESP32 and I would like to share it with you :smiley:.

As far as I understand it is not advisable to use the pins of the ADC2 when working with the WiFi because it causes problems in reading … but what happens if I choose those pins as GPIO or I2C? Do I still have problems using them? :thinking:

being clearer with the question. Are the pins of the ADC2 forbidden pins that should not be used at all when using WiFi?

Greetings.

As far as I understand it, the conflict is between ADC2 and Wifi. So it should be possible to use the pins for other purposes.

I agree with @manuelbl assessment, but really if you want a reliable answer for this question, the Espressif forums will connect you with people who build and support this chip;

Problem only exists with the ADC function.
Normal digital I/O functions work fine - I use all of them :slight_smile:
