lab activities occur during the week of August 27-29. During the week of 8/30
lease go to your regularly scheduled EE345M lab in
ENS252C to hear a TA explain the lab grading policy. Technological Arts
9S12C32 boards will be passed out and lab partners will be selected in your lab
the week of September 6. The Lab 20 preparation is due at the beginning of
your lab the week of September 6. Preparation includes hardware wiring
diagrams and syntax-free assembly 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.
Students
are encouraged to go to the last 2 hours of the other lab periods (including
when EE345L 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 December 3, 12
noon.

Legal Stuff: The 12th class day is September 10. 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.
