I wanted to report an error I got when I was running the example code from the Button library:
no matching function for call to 'Button::Button(int,int)'
I believe this has to do with the PULLUP function, and I searched around trying to find the solution. I found this post (as well as two other posts) that recommended changing PULLUP to BUTTON_PULLUP, but it did not work (I got the error something along the lines of 'BUTTON_PULLUP was not defined in this scope').
I don't think it's anything I did, because all I did was copy the example code from there and ran it. So, I am wondering if anyone is encountering this issue at all -- is your Button library working?
Any help would be greatly appreciated! Thank you. :)
