Hello, i'm trying to program a 80c51 MPU to drive a P-12864-F LCD (powertip, 128x64)... I'm using C language and i have a lot of difficulties... plus it's for my studies' final project I guess all my initialisations are correct (thanks to the T6963 datasheet) but i can't display anything I use the status check and the LCD seams to be ready as the STA0 & STA1 bits are set to 1. If anyone can give me a simple sample code for 80x51 i'll be very glad It would help me to find my errors... Thank you in advance Chris as Hwj (excuse my english...)

For a simple example code in C you might find this useful: http://www.skippari.net/phpBB2/viewtopic.php?t=362 It's for AVR but that shouldn't matter here.
