80C51 microprocessor Keypad integration and Multiplexing 6 - 7 Segment Displays.

In this video we will program an AT89C51 using assembly language to scan a 4x4 matrix key pad and display which keys are pressed on two multiplexed 7 segment displays as well as add 4 more 7 segment displays to simulate incrementing address spaces up to FFFF in Hex.
The program that I am using to write code with is called Keil µVision 5. You can find and download it here: https://www.keil.com/download/product...
As I an not the one who did the actual keypad programming, I will provide you with the link to the individual who actually did do that part of the programming, if you need further instruction on that part of the programming.
