How to initialize keypad and buzzer for pc 18f4520 using c programming?

hi, i need source code for keypad and buzzer for pc 18f4520 using c programming.

check keypad tutorial for keypad interfacing.

buzzer is easy to drive, you can switch it on/off by simply making a pin hi/low.

for keypad,

do i have to define like

#define<keypad.h>?

thanks

for what u mention earlier for keypad, is it for pc18f4520 , as i can not find it

not its a general keypad program written in C, with little modifications you can make it work for PIC also.

you cannot directly add the header file unless its available.

try to go through the keypad program, if you feel any problem please ask.
