The title basically says it all. It shouldn't be to difficult to implement on any PWM/Timer pin. If I end up making one myself I'll share it. I usually don't make class based libraries though, and I would have to re-learn classes again (probably pushing fifth or sixth time I've forgotten most of it.)

if you did something in c only i would probably like it more.

are you shooting for multi-touch or single touch? One is *much* harder than the other...

No, I deferentially wouldn't try to tackle multi-point capacitive touch. I meant for button type capacitive touch, such what touch lamps use. It can be done on one pin, so you should be able to have as many inputs as you have either timer pins (15/16) or pin total (37 on Maple.) With more inputs, the polling time would be slower.

I honestly didn't even think of touch screen type capacitive touch, but that is a good idea.
