This GLCD library is slightly different to the others in one simple respect.

This library makes use of the extra memory available on a PIC32 chip to give a fully buffered GLCD experience.

Usually, when you talk to a GLCD module you directly manipulate its memory. This can be very slow for some operations that require many modifications, like line drawing.

By providing a buffer in the PIC32's memory the drawing (and indeed all) functions are lightningly quick. Only when you have finished setting out the screen do you actually push the image to the display.

At the moment most of the functionality required to use a graphical LCD is provided, but there is certainly room for additional functions.

The [User Interface] is pretty straight forward, and provides a simple way of controlling it.
