Hi all,

How to interface 4 x 4 Keypad with PIC micro-controller (PIC 16F877A) with detail :
The numbers 0-9 will be used as the decimal operands and letters to specify the operation:
F will carry on the addition “ + ” of 2 digits
E will carry on the subtraction “ - “ of 2 digits
C to show result “ = ”.

please code only
