You have the option of proposing alternative labs, forming groups
of ranging from 2 to 4 students depending on the difficulty of
the alternative lab. These groups may include students from other
lab sections. The alternative lab must generally cover the same
educational objectives as the lab you wish to replace.
During the week of September 2, please go to your regularly scheduled
EE345M lab in ENS252C to hear a TA explain the lab grading policy. ImageCraft Adapt812 boards will be passed out and lab partners
will be selected in your lab the week of Sept 3-7. The Lab 13
preparation is due at the beginning of your lab the week of Sept
3-7. 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 7, 12 noon.

Legal Stuff: Drop date is Sept. 3. 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 otherjs 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 peoplesj 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.
