	Homework & Computer Problems	25%
	Midterm Exam	30%
	Final Exam	30%

General Comments

1. There will be short quizzes (about ten minutes) on many Wednesdays. The lowest quiz grade will be dropped. As a result, there will be no make-up quizzes.

2. Homeworks will be assigned most weeks. They will typically be due on the following Wednesday in class. No late homeworks will be accepted. Solutions will be available on the 265 web pages.

3. One week's notice will be given to announce the day of the midterm exam. Make-up exams will virtually NEVER be given.

4. Grading questions should be resolved within one week of the time when the graded work is returned. Check with the TA first.

5. A simulator and assembler are available for the M68HC11 that is used as the basic microcontroller in the text and class. It is used in homeworks especially later ones in the quarter. You can download it off the web to install on your home PC. There is a link for it on the 265 web pages.

HKN Tutor Room

HKN (Eta Kappa Nu) is the Electrical and Computer Engineering Student Honorary at The Ohio State University. HKN manages a tutor room available for beginning Electrical and Computer Engineering students. Schedules can be found outside the tutor room, located in Caldwell Lab opposite to the ECE Lounge, or online at http://www.ece.osu.edu/hkn/. Schedules are subject to change.

Purpose: The purpose of this course is to introduce the student to the concept of a microprocessor/microcontroller as an electrical system component used to help solve real-time problems in control, communications, etc. The student is introduced to the architecture, programming, and interface requirements of a real microcontroller, the Motorola 68HC11.

Goals: The principal goal of this course is to make the student microprocessor/microcontroller literate by introducing him or her to the basic terminology, concepts, and methods used in the solution of problems by incorporating a microcontroller as part of the solution. Although the course is not intended to teach the students how to carry out a detailed physical design, the student should, at the completion of the course, be able to understand, analyze, and evaluate actual microprocessor/microcontroller designs.
