Write an assembly language to interface a keypad and 7-segment display to PIC16F877A and display the key pressed on the key [ad as shown in the picture below. Verify using proteus simulation software.

Write a program to interface a keypad and 7-segment display to PIC1f877a and display the key pressed on the key pad as shown in figure 2 below. Verify your code using proteus mulation software. Your code should be commented to reflect your ideas.
