ADC sampling noise
Posted: Wed Dec 16, 2020 6:04 pm
Hi,
I'm trying to read an analog input using analogRead() with a simple circuit (voltage divider), as you see in the screenshot, there are non stable values given by the ESP32, I have read in the documentation that adding a capacitor and multisampling, the values could improve.
Did you have the same problems when use the ADC?
Any suggestion?
Regards,
Fabricio
