Lab 4 Instructions Complete each task and demonstrate the working program to your tutor. Tasks should be demonstrated using the board provided. You will have two lab sessions to work on this lab, and all questions must be marked by the end of the second session. An example program that uses the LCD is provided on the course page under lab 4. Make reasonable assumptions if something is not explicitly specified. State all those assumptions to the tutor when you are getting marked. Part A keypad (3 Marks) Write a program to detect keypad presses and display them on the LEDs. Buttons 0-9 should display their numeric value in binary, with the LSB at the bottom. The other buttons do not need to be handled. The keypad should be connected to PORTL, with none of the wires crossed over (same as lab 3). The low 4 bits will be connected to the rows, and the high 4 bits will be used to read the column outputs.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
