360 Chatpad.cpp Error (Need Help)

Hello,

Upon interfacing an xbox 360 ChatPad to my arduino(Mega 1280) I ran into a few errors in my code.

I could not make sense of these errors after looking inside chatpad.cpp. Any insight where I should go to? I will take all advice and/or tips, and work from those.

/home/jacob/Desktop/arduino-1.0.2/libraries/Chatpad/Chatpad.cpp:26:20: error: wiring.h: No such file or directory

This library appears to have been designed for wiring, not Arduino. You might be able to use it with an Arduino, but you'll need to change wiring.h to Arduino.h.

Yes. Problem solved, as for syntax errors at least. I must be more observant next time as not to miss things like that. I am going to have to go over the code a few times to understand some of these inputs though.
