Here's a very basic HD44780 driver for Stellaris Launchpad.
Supports up to 20x4 LCD and a full PORTB register is used. Due to the nature of the GPIOPinWrite function which uses masking and whatnots, extra code on the driver will be written in the future to accomodate such functions.
Uses two files: hd44780_lp.c and hd44780_lp.h
An example is in the attachment. It's called "lab2" because I fooled around with the Stellaris Launchpad Workbook earlier.
Note: Please refer to online tutorials on the HD44780 connections.
Comments are greatly appreciated!

R/W pin should not be left floating. Tie it to ground (1 = Read, 0 = Write) - the library just writes commands to the LCD module
