Hello,
I've started a library for the pcd8544 "graphic" lcd controller that is used in Nokia 3310, 5110 and others. It's used most as a text display since you can't read the pcd8544 memory or address individual pixels.
It should work without modifications on both Arduino and the Maple.
Currently only hardware SPI is supported, but I will add support for software SPI soon.
You can get it at github.
Tested on Arduino Duemillanove, Maple rev.3 and Sparkfun's Graphic LCD 84x48 - Nokia 5110.
