Lab Final Review

Dr. Bradley J. BazuinAssociate Professor

Department of Electrical and Computer EngineeringCollege of Engineering and Applied Sciences


Ground Rules

• What you should bring– All the hardware: development boards and complete parts kit– USB drive with all previous lab and project information (code,

reports, schematics, etc.)

• What else you might want to bring– Textbook and data sheets for the HC12 and parts– Written lab reports and schematics– Organized code library of useful stuff on your USB drive

• As a rule: open book, open notes, your own USB memory stick and a lab computer that has the required software and tools.

ECE 4510 2


What makes a good lab final ?

• A question with multiple parts that:– Involves one element that is new

• Has a hardware build that has not been done in a lab yet.• Requires some type of timing relationship between output or input

signals that must be accomplished to operate.• Will require the construction of a main software program and possibly

one or two functions to operate the new hardware.– Involves multiple element that are familiar

• Incorporate peripheral elements involving hardware and software that have been accomplished in a lab or project.

• Existing software initialization and operational function calls can be readily copied and used in the code.

– Has identifiable levels of operational success so that scoring can be directly related to what has been accomplished.

ECE 4510 3


Studying vs. Organizing

• Studying is great but …• Reviewing and organizing all the work requested and

performed in the labs and projects may be better.– If a lab and task is mentioned, can you find the schematic and code

quickly?– If a hardware item is mentioned (for example an LM35), can you

find the schematic and code that is needed to use it?

Project #1: One Dimensional Ping Pong

• Objectives:The project is intended to have student teams independently apply their hardware and software design experience from labs 1-4 to develop a game, one dimensional ping pong.

1. Using parallel I/O pins and the LED bar, make the lights turn on one at a time from right-to-left and left-to-right.

2. Use the ECT to have the lights stay on at each position for a defined period of time. The longer the process continues, the shorter the on-time should be.

3. Use the IRQ interrupt to indicate when the LED bar light in either the farthest right or farthest left position is on.

4. Use the 5x7 matrix display to provide information and the current score to the user. The current score should consist of a count of how many times the LED as moved from one side of the LED bar to the other. Information should include when to start the game (ready) and when it is over (end). Useful information may also include the previous score or a “light show” of LED patterns prior to the start or after the end.

5. (ECE 4510 Optional/ECE 5530 required) The SCI0 port can be used to output messages to a PC terminal window allowing text to be sent and received . The SCI0 port can be used to provide start and stop information as an alternative to the 5x7 matrix displays. The SCI0 could also be used to display the highest score achieved or other text messages. (e.g. enter the users name, instructions, etc.)

6. Make a one-dimensional Ping-Pong game with the above pieces.
