FAQ
The Touch Kit library on this page doesn't work for me. I get the following compile error: 'CapaTouch' was not declared in this scope. I already had a library called 'MPR121' so I had to rename the folder and re-zip it as 'dfrobot_MPR121' in order to add to my library manager. This shouldn't make a difference should it? Please advise.
It seems that the library is not installed successfully.
