This TrackPoint library is used to interface with a TrackPoint module that is available on most ThinkPad keyboards. It can also be used as a general purpose PS/2 mouse library.

Library supports stream mode using interrupt.

Tested with an Arduino Leopard. Solution compiled in Visual Micro, but can also be opened with Arduino IDE.

Circuit: a ThinkPad T60 TrackPoint module (ripped from broken keyboard) connected to an Arduino Leopard. See comments in .ino for more connection information.

Library: TrackPoint.cpp, TrackPoint.h

Example: TrackPoint_INT.ino
