You will find some hints in interfacing LCD: http://www.c51.de ("Software" and "Appnotes") http://www.boerde.de/~matthias/m8051/ ("LCD-driver for Hitachi HD44100/HD44780") http://www.8052.com ("Code Library") Please use the enormous potential of Internet and use search engines e.g. google! Martin

"how do i test weather the lcd is working" That's the trouble you get with ripping custom parts out of other people's equipment!
What routines have you written.Does it cater for lines or characters to be draw?
i haven written some source code for 8051 to lcd....but it can't work can somebody help up ? how do i test weather the lcd is working
I believe with standard SPI communication. And the only external component needed is a 10 uF electrolytic capacitor from VOUT to GND. I have to say that it's just my theory haven't tried it jet.
