Hey!! I have some problem conneting my ATMEL 8051 kit to an LCD.. The LCD seems to be workin well but the program i write does not seem to get transferred.. I mean i have checked the program and it seems to be perfect but I am not gettin any output in the LCD.. Do we need to initialise it?? The LCD we use is a DMC 16249 and the kit is a EDS 8051 ATMEL kit..??[/b]
 

Yup! you have to initialize the LCD display, for an detailed information check this excellent tutorial/engineering notes from shelly inc.
http://www.shellyinc.com/tecsup.htm
To be specific, check the "Instruction Codes" and the "Initialization and Reset" Sections.
By the way, don't forget to adjust the contrast for the LCD display, the first time I used an LCD I spent hours trying to find out why it didn't work only to find out that the problem was that it was working but the display was too dim so I didn't see the text.
Regards,
