Text	MC68HC11:An Introduction, Software and Hardware Interfacing, 2nd Ed. by Han-Way Huang, published by Delmar Thompson Learning You will 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%
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.   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.

Homework 12 deadline extended to Friday November 21st 33 Nov 21 The SPI (synchronous serial) subsystem. 34 Nov 24 Meet in Lab (HH 319) during the regular class time. Be on time. We'll start with this program, before implementing the EEPROM portion of your "second meter" 35 Nov 26 Meet in Lab (HH 319) during the regular class time. Be on time. We'll start with this program and the associated circuit. We will run this program out of the on-board RAM (as we have been doing all semester), the on-chip EEPROM, and then from a larger on-board EEPROM/FLASH memory unit. Build your circuit on a separate breadboard in case you don't finish it all today (I just put some new breadboards up in 319, you need to stick the metal sheet on the back prior to use). Nov 28 No Class. Day after Thanksgiving. 36 Dec 1 Go over Motorola/Hitachi timing example. Homework 14 assigned for Wednesday, Homework 15 assigned for Friday. 37 Dec 3 Meet in Lab (HH 319) during the regular class time. Be on time. Those that are behind will need to finish up last Wednesday's assignment for partial credit before demoing their "second meter". The "second meter" should be complete, e.g. it now needs to store the time in EEPROM under program control. 38 Dec 5 Meet in CEH 351. Go over read-cycle and write-cycle timing some more. 39 Dec 8 Meet in CEH 351. Teaching Evaluations. Discuss selecting a microcontroller for your own (Senior Design or "real world") project. Also please read this EDN article: Putting the Squeeze on 16 bit microp 40 Dec 10 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 . . . . . . . . .
