eh. that is the most common use of microcontroller
interfacing with lcd and keypad
the schematic is simple. just connect the lcd, keypad pins to pic I/O pins
Have a look at my tutorials at http://www.winpicprog.co.uk which do all that you need, but to get them all at the same time you will need a larger PIC or extra hardware.
