Create Keypad_&_7SegDisplay.c

This c program connects the pic microcontroller up to a 4 by 4 keypad (via 8 pins using matrix) and a two digit 7-segment display. After assigning values to each button on the keypad, the program will display the latest hex-digit (0 - F) on the right most digit of the display while the left most digit of the display will show the digit pressed previously. Since this display does not have enough pins to connect to all segments on both digits (and neither does the microcontroller for that matter) the display is multiplexed at a fast enough rate to go unnoticed by the human eye.
