I'm trying to set up a capacitive sensor. I tried the CapacitiveSensor library by Paul Badger but found it unreliable and it would give readings when there was no touch. I then found the ADCTouch library by martin2250 which was exciting and seemed to work great. I tested it on my Uno and it worked perfectly.
Since my project uses communication via WiFi I then tried to upload the simple test sketch, Buttons.ini to my Uno WiFI R2 board. I immediately received the following errors.
"WARNING: library ADCTouch claims to run on avr architecture(s) and may be incompatible with your current board which runs on megaavr architecture(s)."
with additional errors:

What do I need to add to make this work as it does on the regular Uno board?
I did try an additional library called ADCTouchSensor by Alexander Pruss but I got the same errors.
Has anyone had similar experience or know a direction I could take to resolve the issue?
Thanks so much,
