AVR LCD

Description
Connecting a Hitachi HD44780 compatible 2x24 character display to an AVR microcontroller in 4-bit mode.

Hardware
I use a STK500 for development so a little interface board is needed to connect to the display:
ATmage16 interface
ATmage8 interface

Project log

2008-03-03 I changed the text above. It stated that I wanted to connect the display to a AT80S8515. I once did. That was a long time ago before I managed to blow it up (don't ask), and I've been working with an ATmega16 since.
Secondly I also managed to port the code and make new hardware for the ATmega8.

2008-02-23 Ok, I gave it another stab. Seems I made an so obvious mistake in my code that I could not see it. It really irretates me, but fine, it works now. Time to move on.

2007-09-08 It doesn't work. I double checked my code, and ran it in AVR Studio, it should be alright. Next step will be to check the wiring connections again. There's a possebility that I might have crossed some of the data pins.
