LC7981/HD61830 Driver for EL Backlit Samsung LCD
I’ve found the time to post this LC7981/HD61830 driver (only graphics mode implemented) and some images of this Samsung LCD I’m using. I bought the LCD off of ebay ( http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=230070938443 ) and shortly after I wrote the driver for it from scratch. I finished this driver about a month and a half ago, but I have just been too busy lately to post anything about it till now.
This is will eventually be a part of my GPS project, which I will get into later next week.
For now, here are the specs: an EL backlit 160×80 monochrome graphics LCD that supports text and graphics mode (I just coded for graphics mode and found a font/character pixel set online), controlled by an ATMega32. The LCD is driven by an LC7981/HD61830 controller (easy parallel interface). I’ll try to get the pinout up, including the EL connections with the inverter as soon as possible.
Pictures (no, I’m not running linux, the linux penguin just happened to be a convenient pixmap to demonstrate):
And the free source, currently coded for the ATMega32 but can be easily adapted to other uCs: avr-lc7981.tar.gz.
