HI There is some very useful information about LCD at these links. http://www.8052.com/tutlcd.phtml http://home.iae.nl/users/pouweha/lcd/lcd.shtml do check them And as far as the keypad is concerned interface it with the same Ucontroller to which lcd is attached. Check out the pin layout of the keypad. how many rows and columns your keypad have?
