gorpi-lcd
The online Adafruit LCD tutorial uses an Python example: http://learn.adafruit.com/drive-a-16x2-lcd-directly-with-a-raspberry-pi
I wanted to stick with the new language I'd been learning (Google Go).
So I found a gpio library (http://github.com/davecheney/gpio), and updated it a bit along then worked up this LCD program that you can use to drive the LCD panel.
See example files under /examples for .. well examples.
This has been tested to work with the same hardware given in the adafruit tutorial. Other hardware.. YMMV!
