Texts	MC68HC11:An Introduction, Software and Hardware Interfacing, 2nd Ed. by Han-Way Huang, published by Delmar Thompson Learning. In addition to the above text, you should print out a copy of the M68HC11E Series Programming Reference Guide . You should bring a hard copy of this document to every class (and to lab). You will also want to consult your textbook and other references from your programming course(s) These texts will be supplemented with additional reference materials which will be linked from this page and/or handed out in class as they are assigned.

Prerequisites

To take this class, you must have earned at least a C in EE 245 and successfully completed either CSc 218 or CSc 250.

Corequisites

EE 347L -- Microcontroller System Design Lab has a separate web page. You will not need to purchase an additional text for this lab.

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%
Practical Lab Assignments	20%
Lab Project and PDR	15%
Lab Practical Exams(s)	10%

Your class participation grade will be determined by your on time attendance to class as well as your participation in classroom discussions. You will probably need you printed Reference Guide (see above) in order to participate and to receive these points. Pop quizzes, when given, will cover material previously covered in class, previous homework assignments, and/or simple questions on the current days reading assignment.   Students are required to make a "good faith effort" on all assignments. Failure to do so will adversely effect the grade beyond the limits listed above. You must earn a grade of C or better in EE 347L this semester in order to pass this class 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.

We will first run it out of external RAM (as we have been doing all semester). We will then run it out of the on-chip EEPROM See "Single Chip Applications" on page 10 of the Axiom CME11E9-EVBU Manual). We will then run it out of the (much larger) on-board flash memory (See "Programming External EEPROM" on page 8 of the same reference). You should bring your "second meter" so that you can demo that after completing the other tasks. 32 Nov 20 Which Microcontroller should I use? Meet in SECS 0218 33 Nov 23 Current and Future trends in Microcontrollers. How Flash based micro help with time to market and decrease costs, system on a chip. This material is not in your book, but a quick google-search yielded the following three articles which seem to cover the current trends: Memory options: flash may dominate from EDN (in general, EDN is an excellent resource) A piece on the evolution of flash microcontrollers, and a wikipedia article on System on a Chip 34 Nov 25 . . .
