capsense pin assignments?

Hi all. I am looking at making a small array of capacitive touch switches using the capsense library.

They use pins 2,4,6 etc and I'm wondering why they omit pin 3 for example. Could another pins be used if configured correctly, how about using analog pins?


Capsense uses standard digital IO functionality, and doesn't use pwm or analog, therefore can be used on any IO pin, including pin 3 and the analog ones (since the analog ones can also be configured as digital IO pins).

Thanks for clearing that up :)

I wonder why everyone seems to use the even number pins :~

Thanks again :)
