CP316: Microprocessor Systems and Interfacing

Liquid Crystal Display (LCD) Prelab

The objectives for the LCD lab are:

You will first observe the LCD output when the LCD is not initialized.  Then you will initialize the LCD with the requested characteristics.  Note: the initialization is the critical point in the lab. 

Prelab Deliverables:

  1. Construct a program that puts out a tick as a high priority interrupt based on timer0. The interrupt service routine should toggle the alive LED on the board. The mainline routine for this program would  initialize the standard ports and then the routine should go into an infinite loop. The tick interval is not important for the prelab but you should know what it is, how to measure it, and how to modify it to suit specific applications. This should be a simple modification of Question 6 from the previous lab. Come to the lab with this base program completely working.

  2. In preparation for the lab, you should
