-Throughout Unit 3 and Labs [[https://reference.digilentinc.com/learn/courses/unit-3-lab3a/start|3a]] and [[https://reference.digilentinc.com/learn/courses/unit-3-lab3b/start|3b]], you will learn how to interface a PIC32 processor to a character liquid crystal display (LCD) using 8-bit parallel data lines and handshaking using bit-banging techniques. You will learn to translate timing diagrams provided by target equipment data sheets into timed sequences of program instructions. You will also learn how to use ASCII encoded data and control to generate a stable and easily readable display of real-time data.+Throughout Unit 3 and Labs [[/learn/courses/unit-3-lab3a/start|3a]] and [[/learn/courses/unit-3-lab3b/start|3b]], you will learn how to interface a PIC32 processor to a character liquid crystal display (LCD) using 8-bit parallel data lines and handshaking using bit-banging techniques.

 You will experiment with the mechanisms required to synchronize asynchronous systems using hardware and software handshaking, as well as explicit and implicit handshaking. You will build a project that consists of multiple C files. We will also look into using variables in software macros. You will experiment with the mechanisms required to synchronize asynchronous systems using hardware and software handshaking, as well as explicit and implicit handshaking.

     * The 2X16 LCD included on the Basys MX3 processor board can display 16 characters on each of its two lines. The display can be more easily viewed if the LCD backlight is switched on using the slide switch SW9.     * The 2X16 LCD included on the Basys MX3 processor board can display 16 characters on each of its two lines.

     * Note: Fig. B.1 through Fig. B.4 in Appendix B shows an Analog discovery 2 connected directly to the LCD data pins and the three handshaking and control pins: RS, R/W, and EN. This custom modification was made to enable testing during software development. It is not required to make this modification in order to complete Lab 3a and Lab 3b. This is further explained in Appendix B.      * Note: Fig. B.1 through Fig. B.4 in Appendix B shows an Analog discovery 2 connected directly to the LCD data pins and the three handshaking and control pins: RS, R/W, and EN.
