Lab 3: Basic Calculator Datasheets and Manuals 4x4 Keypad Datasheet LCD Display Datasheet Microchip 16-bit 28-pin Starter Board User's Guide PIC24FJ64GA002 Datasheet PIC24F Family Reference Manuals PICkit 3 User's Guide Parts Needed for Lab (all parts are provided in your team's Parts Kit) 1 - 8x2 LCD Screen (1.50” x 1”) 1 - Keypad (4x4) Male Headers Optional: 4x4 Vector Prototype Board Lab Overview: In this lab, you will build a basic calculator capable or performing addition, subtraction, multiplication, and division of 2 digit decimal inputs. This lab assignment will interface to a 4x4 Keypad for user input, and will require implementing a keypad scanning functions along with configuring the keypad to utilize change notification interrupts. The LCD software driver developed in your previous lab assignment will be utilized to display results using the 8x2 LCD Display. NOTE: As you will be incorporating additional components with your PIC microcontroller, those components can either be directly integrated in the prototyping area of the 16-bit 28-pin Starter Board or using a separate prototype board. Each team is provided with a prototype board within their Parts Kits. If your team decides to integrate the components in the prototype area of the Starter Board, of the team member must be willing to use his/her board for this purpose. Provided Software Code: Source Code for Lab 2: lab2.c , keypad.h , keypad.c Lab 2 Procedure: 1. Part 1: Keypad Interface and Keypad Scanning Driver

    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.
