what can I do with this LCD?


New member

I have a 20x2 serial LCD from a POS customer display;

It has two boards, one that has the LCD panel itself, and another with amongst other "parts" two chips:

ATMEL 9843 - AT89C2051-24PC

KA1489A - 336B

The LCD module is a SDEC LMC-BSC2B20-01 serial

I can output to it using LCDproc under linux, or even Crystalfontz software under windows, but the data on the display keeps scrolling very randomly, and all sort of garbage appears.

I have its data sheet, but I'm can't understand anything that comes in it (I'm not a programmer)

Does anyone have any information I can use to try to make it work with lcdproc, for example?

Thanks for any help,

Gustavo Melo

I took these pictures, might help identifying it... my guess is the controller is under one of the two black plastic "seals"...
