'RemoteXY.begin' was not declared in this scope. I have install the latest RemoteXY library. Anyone can help to troubleshoot? Thanks in advance

Welcome to the forum

Do the examples from the RemoteXY library work ?

3

This sketch on the RemoteXY web site looks different (RemoteXY.init() v RemoteXY.begin()).

6

Yup. It's work well.

7

Please post an example sketch that works
Does it use the RemoteXY.begin() function ?
