Course Description

This course serves as an introduction to microcontrollers, using the MC68HC11 as an example.

Course Work

Unless otherwise specified, all work that you submit in this course must be your own; unauthorized collaboration is considered academic dishonesty. Please save us both a lot of trouble by realizing that I will pursue any such transgressions to the fullest extent possible. As a rule, late assigments are not generally accepted (e.g., attempting to hand in an assigment after the start of class on the due date will result in a grade of 0 for that assignment). Late assignments will only be accepted under exceptional circumstances AND with prior arrangement. A penalty may apply.

Grading Policy

Final grades will be determined via the following breakdown:

 

Exam #1	20%
Exam #2	20%
Homework and Quizzes	10%
Class Participation (and quizzes)	5%
Design Lab Practical(s)	10%
Lab Project and PDR	15%
Comprehensive Final Exam	20%

Your class participation grade will be determined by your on time attendance to class as well as your participation in classroom discussions. Pop quizzes, when given, will cover material previously covered in class, previous homework assignments, and/or simple questions on the current days reading assignment.   Please read Making the Grade by Kurt Wiesenfeld and keep his views (which I share) in mind when deciding how much effort to invest in your coursework.

Check your email and this web page prior to each class so that you'll know when and where to go (don't forget to hit "reload" or "refresh" 35 Apr 18 In HH319 at both Noon and 1:00 PM I would like all 9 people who volunteered (by signing the sign up sheet) to show up at 1:00. The rest of you, please come at Noon. There is no assignment, but bring some way to transfer files from the lab computers to your home. (web-based email, floppy, USB stick known to work in the lab, etc). I will give you a program, and a circuit description. You will build the circuit and we will experiment with loading the S19 file in RAM (as usual), the on-chip EEPROM, and the on-board flash. We will then be able to run w/out being tied to the PC (and, in the case of the on-chip EEPROM, in single-chip mode on the axiom boards. 36 Apr 20 In HH319 at both Noon and 1:00 PM We'll be working with writing to the on-chip EEPROM under program control. We'll start with this program and modify it as we go along. Bring a calculator, your notes on the on-chip EEPROM, and your notes on the serial comm. subsystems. Also bring your homework regarding the "minute meter" and the bottle counter. Homework # 16 assigned. Due Friday 37 Apr 22 In HH319 at both Noon and 1:00 PM Come to class prepared, with a soft-copy of your solutions to Homework # 16 Homework # 17 assigned 38 Apr 25 In CEH 351 at Noon ONLY 39 Apr 27 In HH319 at both Noon and 1:00 PM Come to class prepared, with a soft-copy of your working solutions to Homework # 16 and a soft copy of your solution (and circuit diagram for Homework # 17 40 Apr 29 In HH319 at both Noon and 1:00 PM Last chance to win some pies! First group to get the in class assignment done gets to split 3 pies. My turn at the pie toss is from 2-2:30.... May 02 Optional Review Session at 5 pm in Crothers 351.
