For your information, there is an application note available on this site AN1048 which is about driving the LCD directly using software without the need of any LCD hardware driver chip.

thanks a lot to Ranjeet
I have just looked at your assembly source code and I wrote a code for my LCD. Just another question: my LCD has four lines. I set it with two line because I don't know how to set for four lines. So, when the first line is full, with shift option, the LCD starts to fill the third line. After that the second (I think it consider the first and the third as one line). have you got any suggestions? thanks echoes2004-04-20 12:51 AM
Pls check the address of the first character in the second line. May be its not continuous with the first line.
