lcd interface with atmel 89c51

hi
can somebody help me with source code of lcd and keyboard interface with atmel 89c51.
thank u.

I suggest to post the schematic of LCD, keypad connection PERMANENTLY in somewhere of this forum.
I've seen many people requesting LCD connection for different type of microcontroller. However, basically the connection and firmware are the same for all microcontroller, except for the change in the pins used in microcontroller.
Right?
