I have started using the Lilygo T-Display-s3, and in my application I connected GPIO12 to measure an analog voltage between 0 and 3Vdc.
I should be pretty straight forward, I set the PinMode for GPIO12 as INPUT and used the ReadAnalog function with the GPIO12 pin (12)....
However, for some reason it does not read the voltage at all....
GPIO12 is supposed to share operation with the ADC2 CH1, is there any setup that is required, that I'm not familiar with?
