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.
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: 40% Laboratory
15% In class Quiz1, open book, Wednesday, March 6, 11:00
am to 11:50 am, in regular class room
15% In class Quiz2, open book, Wednesday, April 10, 11:00
am to 11:50 am, in regular class room
30% Final, open book, Wednesday, May 8, 9am-12noon, regularly
scheduled
Your grade will be assigned on the usual 60, 70, 80, 90 basis.
An average above 70 is required to receive a credit (CR/NR).
Lab Partners: All labs should be performed with a partner. The
lab partnership must be registered with the TA (a simple hand
written note signed by both students will suffice) at least a
week before the assignment is due. 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".
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 21, please go to your regularly scheduled
lab in ENS252C to hear a TA explain the lab grading policy. If
you miss your section, go to one of the other sessions. ImageCraft
Adapt812 boards will be passed out and lab partners will be selected
in your lab the week of January 21-25. The Lab 1 preparation is
due at the beginning of your lab the week of January 28-February
1. Preparation includes hardware wiring diagrams and syntax-free
software printouts. In other words, please type your software
into the PC before lab. The lab preparations (hardware diagrams
and syntax-free software source code printouts) are due at the
beginning of your lab period. 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 (including when EE345M labs are scheduled), but the
first priority will be to the regular students. Because of the
lab quiz, the first hour of lab is restricted to the regular students.
CLEAR OUT BY 15 minutes before the start of lab. 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 3, 12 noon.

Final exam, 9am-12noon, Room regularly scheduled
Legal Stuff: The 12th class day is January 30. 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. 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 peoples' 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.
