Teaching philosophy
I strongly encourage students to take an active role in this class.
Questions are welcome before, during and after class. Please feel free
to email, visit or call me if you have questions.
Specific Objectives of EE345L
The primary objective of EE345L is for the students to develop the

Special Topics
About 1-2 weeks each semester will be allocated to cover special
state-of-the-art topics involving embedded microcomputers and
their applications.
After the successful conclusion of EE345L students should be able to
design the hardware/software interface for devices like LCD displays,
motors, keyboards, analog sensors and speakers..
Attendance: Students are expected to attend lectures. The book
covers more information than the class and we will use lectures
to map our way through the book. If you miss class you may find
it difficult to catch up.
Grading:
35% Laboratory
5% Unannounced pop quizzes,
closed book, in regular class room
5% Weekly
multiple-choice online homework
15% In class Quiz1, closed book, Wednesday, March 2, 1:00 to
1:50 pm, in JES A121A
15% In class Quiz2, closed book, Monday, April 11, 1:00 to 1:50
pm, in JES A121A
25% Final, closed/open book,
Saturday, May 14, 9am-12noon, regularly
scheduled
Cutoff scores for the corresponding letter grades will be announced
after the second quiz.
Lab Partners: All labs should be performed with a partner. The
lab partnership must be registered with your TA (a simple hand
written note signed by both students will suffice) during the week of
1/24 to 1/28. Once registered, the partnership
will continue. A partnership can be dissolved only after discussion
with the TA. Both partners must be present during the demonstration.
It is expected that both partners will contribute to all aspects
of each lab, and both partners are expected to be present during
the check out. The point values are the same for all labs. The
TA will sign your software listing when you demonstrate your system.
All parts of the assignment must be demonstrated to a TA by the
end of your lab period the week shown in the column labeled "Demo/Report".
Any EE345L TA is authorized to checkout your lab. The report (hardware/software/data plots) are due one day after
the demonstration is due. Please consult with your TA for specific
due dates for your lab section.

During the week of January 24-28, please go to
your scheduled EE345L lab sessions in ENS252C to
get a demonstration of the lab equipment. If you did not get a
TechArts 9S12C32 kit in EE319K, then a kit will be given to you. Each
student will get exactly one kit. If you loose it or destroy
it, you can purchase another from Technological Arts for $50 plus shipping.
For more information on purchasing a replacement kit, go to the
http://www.technologicalarts.com/ web site and
click the University of Texas at Austin link (order NC12C32SP). Lab partners will be selected
in your lab the week of Jan 31 to Feb 4. The Lab 1 preparation is
due at the beginning of your lab the week of January 31-Feb 4. The lab preparations (hardware diagrams
and syntax-free software source code printouts) are due at the
beginning of your lab period. In other words, please type your software
into the PC before lab. Attendance in lab is required. All
software for lab, and tests must include comments. All hardware
must include R&C values specifying tolerance and type (e.g., 5%
carbon), and TTL chip numbers (be very specific e.g., 74LS00).
Pin numbers are required only for lab, not for the exams.
Students are encouraged to go to the last 2 hours of the other
lab periods, but the
first priority will be to the regular students. During the first 15
minutes of lab, the TA will collect preparations and give a quiz.
For the next 30 minutes, the TA will lead a
lab discussion session. The remaining lab time is available for
debugging and lab checkout. At the end of
the semester please verify with the checkout counter that your
record is clear. All reports must be given to the TA by Friday
May 6, 12 noon.

Legal Stuff: The 12th class day is Feb 2. After this date, I will sign
a drop only if the Dean approves it. Your current grade status
must be a "C" or better for you to receive a "Q". Course evaluation
is conducted on the last class day in accordance with the Measurement
and Evaluation Center form. The final exam is at the time and
place stated in the course schedule. The University of Texas at
Austin provides upon request appropriate academic adjustments
for qualified students with disabilities. For more information,
contact the Office of the Dean of Students with Disabilities at
471-6259, 471-4241 TDD.
Cheating: Cheating is very uncivilized behavior and is to be avoided at
all cost. We will be using an automated system to check for software plagiarism.
You are allowed to talk to your classmates about the
lab assignments, but you are NOT allowed to look at each other's
written work. Oral discussion about an assignment is encouraged
and is not considered to be cheating. Copying of any part of
a program is cheating without explicit reference to its source.
If we find two programs that are copied, there will be a substantial
penalty to both students, e.g., failure in the course. Students
who cheat on tests or in lab will fail. Prosecution of cases is
very traumatic to both the student and instructor. PLEASE DO YOUR
OWN WORK. Policies concerning the use of other people's software
in this class:
• I strongly encourage you to study existing software.
• All applications and libraries must be legally obtained. E.g.,
You may use libraries that came when you bought a compiler.
You may use software obtained from a BBS or on the WWW.
You may copy and paste from the existing source code.
• You may use any existing source code that is clearly referenced and categorized:
original: completely written by you,
derived: fundamental approach is copied but it is your implementation,
modified: source code significantly edited to serve your purpose,
copied: source code includes minor modifications.
When studying, focus on the topics that apply to the 6812 and the topics included in the lab assignments.
You will find old quizzes and finals with solutions on the class web site.
