Windell has posted am Arduino basic-function library for EMS Labs’ Peggy 2.0 LED light-board kit.

This brings Peggy 2.0 up to the level of having useful compatibility with the Arduino software environment: you can use high-level commands to control what shows up on the Peggy display. For example, the type of high-level command might be something of the form “Peggy_SetPoint(x, y)” which would turn on the LED located at position (x,y) in the grid.
