Re: ADC issue
But the 100 ohm resistor is not connected to the ADC pin, only to V3 or another GPIO.

ADC issue
When I put a standard red LED with a 100ohm resistor on a gpio (or just between ground and V3) on my black pill, and I connect PA6 to ground with a 10K resistor, analogRead(PA6) returns around 300 when the LED is on, and 0 when it's off. Is 10K not enough for a pulldown?
I don't have any issue ...
