Hi, I'm facing problems to read analog values in A10, A9 and A8, using capacitve soil moisture sensor with XIAO expansion board attached.
obs.1: When change to A1, performs normal reading.
obs.:2: When applied resistive sensor performs normal reading in A10, A9 and A8 pins.

Hi, unless I'm mistaken your "Digital as PWM" is actually just analog output, and not PWM ?

Actually I have checked, and the examples does output a square signal whose width varies. But then, no true analog output ?? I've tried modifying the pin_mode, to no avail ;(
