Ian Kilburn / FRDM_KL46Z_LCD

Brought over the files from the Freescale site and modified for mbed.

This code is only partially working for me. Not every download seems to be successful on Mac OS X. I just took the example files and hacked them around to get it working with mbed. If you want working code I think Erik Olieman's SLCD project is probably a better source.
