Academic Honesty
All students are responsible for maintaining the highest standards of honesty and integrity in every phase of their academic careers. The penalties for academic dishonesty are severe and ignorance is not an acceptable defense. The document for academic honesty may be found at the web site for The University of Georgia Office of Senior Vice President for Academic Affairs and Provost.

Departmental Grading Policy Regarding Communication Skills
Thirty percent of the grade on all written assignments (lab reports and papers) and oral presentations will be based on quality of communication. Spelling, grammar, punctuation, and clarity of writing are evidence of written communication quality. Enunciation, voice projection, clarity and logical order of the presentation and effective use of visual aids are evidence of oral communication quality.

Engineering Professionalism Policy
Engineers make great contributions to society. Engineering is a very satisfying profession that provides many rewards but is demanding and requires hard work. The engineering profession is governed by a code of ethics. Engineering faculty at UGA expect students to act in a professional manner at all times and develop the work ethics required for a successful engineering career. Engineering students at UGA are responsible for maintaining the highest standards of professionalism and professional practice

Class Rules:

Lab reports are due one week from the day lab is completed. Late labs will cost you 10 points per day. (Exceptions will only be made based on documented emergencies).
Homework assignments are due one week from the day assigned unless specified otherwise. Late assignments will cost you 10 points per day (Exceptions will only be made based on documented emergencies).
Questions about test, homework or lab grades should be brought to my attention after class in my office and will not be discussed during class periods.

What To Expect out of This Class:
In the first microcontroller class, we learned the basics of using the MC68HC11 as a monitoring and control device. We learned about the architecture of the HC11, its input and output ports, its assembly instruction set, and its EVB development board. In this class, we will rely heavily on this background knowledge while accomplishing several new goals. The most important of these goals are:

Learning how to use the HC11 for solving monitoring and control problems of the type encountered in industry.
Learning how to use more advanced features of the HC11.
Learning how to develop Interrupt driven programming as opposed to sequential programming.
Learning how to develop more complex software.
Incorporating more sophisticated hardware/interfacing issues.

In order to accomplish these goals, I have chosen to build the course around a design project that is based on an actual industry application. This project consists of developing an HC11 based monitoring and control system for a variable speed DC motor.

What hardware components are needed to develop the system?
How will the different hardware components be interfaced with the HC11?
What features of the HC11 are needed to develop this system and how do we make use of them?

We will address each component of this project individually through lectures and laboratory assignments. You will be required to turn in lab reports for each individual laboratory as well as a final project lab report.
