Old exams
Other references: For programming in C and digital logic, see the EE312 and EE316
texts
Prerequisites: EE312 and EE319K with a grade of at least C- in
each; EE411 and EE313, or BME311 and BME343, with a grade of at least C- in
each; and credit with a grade of at least C- or registration for BME333T, or EE333T.
Specific EE319K topics needed for EE445L: LED interface, switch
interface, busy-wait synchronization, serial communication concepts (start bit,
data bits, stop bit, baud rate, bandwidth), UART programming, analog to digital
conversion (range, resolution, precision, accuracy), ADC programming, digital
to analog conversion (range, resolution, precision, accuracy), interrupt
concepts (arm, enable, acknowledge, vector), Output compare interrupt
programming
Specific EE312 topics needed for EE445L: Modular programming,
differences between pointers and numbers, when to use permanent allocation and
when to use temporary allocation, definitions of char, short and long,
understanding and use of static, const and volatile,
understanding call by value versus call by reference, stack frames, structures,
linked lists, fifo queues, verification. The most important component students
must be able to accomplish is the translation of a problem statement into
software code. The second most important skill we expect students to have is
the ability to debug software.
Specific EE411/EE313/EE438 topics needed for EE445L: RLC circuits, NPN
and PNP transistors, input impedance, output impedance, linear amplifiers using
op amps, oscilloscopes, sampling, frequency response, Bode Plots, Fourier
Transform, spectrum measurements.
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 EE445L The primary objective of
EE445L is for the students to develop the ability to design microcomputer-based
embedded systems. This class allows students to learn microcomputer interfacing
from both a hardware and software perspective.

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 :
40% Laboratory assignment with
a large weight applied to Labs 8, 9 and 11
15% Quiz 1, closed book, Friday,
October 7, 2:00 to 2:50 pm, ACA 1.104
15% Quiz 2, open book, Friday,
November 18, 2:00 to 2:50 pm, ACA 1.104
30% Final, closed/open book, Wednesday,
December 7, 2-5pm, regularly scheduled time and place
When studying, focus on the topics that apply to
the Arm Cortex M3 and the lab assignments. You will find old quizzes and
finals with solutions on the class web site. I have no expected grade
cutoffs or expected GPA for this class. You can view the previous GPAs for most
of your classes at UT (MyEdu reports I give a GPA in this class of 3.25).
All professors want a 5 on their teaching evaluation, and all students want an
A. However, I feel both should only be awarded for excellence.
Lab Partners: All labs should be performed with a partner. You and your
lab partner must be registered for the same lab section. The lab partnership
must be registered with your TA (a simple hand written note signed by both
students will suffice) during the week of 8/29 to 9/1. 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. Lab partners will be selected in your lab the week
of 8/29 to 9/1. If you want to switch sections, log your request onto the first
page of the wiki. Once you find someone willing to swap sections, the two of
you should go to an undergraduate advisor.

EE445L Laboratory Schedule (see your TA for the latest). Each
week there are two 90 minute lab sessions, which are scheduled Monday/Wednesday
or Tuesday/Thursday. You will show the preparation to your TA at the beginning
of the second session. During the first session demonstrations will be made.
The TA will sign your software listing when you demonstrate your system. The
report (hardware/software/data plots) is due Friday at the beginning of
recitation. Any EE445L TA is authorized to checkout your lab. Please
consult with your TA for specific due dates for your lab section.

During the week of 8/29 to 9/1, please go to your
scheduled EE445L lab sessions in ENS252A to get a demonstration of the lab
equipment. If you do not already own a LM3S1968 board, you must purchase
one. Boards can be purchased for $49 using Bevobucks during the first three
days of the semester. Each student should have their own board. 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 chip numbers (be very specific e.g., INA122P). Pin numbers are
required only for lab, not for the exams.
Students are encouraged to go to the last 1 hour 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. For the
next 15 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 December 2, 2pm.
This is an approximate schedule, please check the
website for the latest version.

Legal Stuff: The 12th class day is September 9. 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.
Scholastic dishonesty: "Faculty in the ECE Department are committed
to detecting and responding to all instances of scholastic dishonesty and will
pursue cases of scholastic dishonesty in accordance with university policy.
Scholastic dishonesty, in all its forms, is a blight
on our entire academic community. All parties in our community -- faculty,
staff, and students -- are responsible for creating an environment that
educates outstanding engineers, and this goal entails excellence in technical
skills, self-giving citizenry, an ethical integrity.
Industry wants engineers who are competent and fully trustworthy, and both
qualities must be developed day by day throughout an entire lifetime.
Scholastic dishonesty includes, but is not limited to, cheating, plagiarism,
collusion, falsifying academic records, or any act designed to give an unfair
academic advantage to the student. The fact that you are in this class as an
engineering student is testament to your abilities. Penalties for scholastic
dishonesty are severe and can include, but are not limited to, a written
reprimand, a zero on the assignment/exam, re-taking the exam in question, an F
in the course, or expulsion from the University. Don't jeopardize your career
by an act of scholastic dishonesty. Details about academic integrity and what
constitutes scholastic dishonesty can be found at the website for the UT Dean
of Students Office and the General Information Catalog, Section
11-802."
You are encouraged to study together and to discuss information and concepts
with other students. You can give "consulting" help to or receive
"consulting" help from such students in oral form. However, this
permissible cooperation should never involve one student having possession of a
copy of all or part of work done by someone else, in the form of an email, an
email attachment file, a portable storage device, or a hard copy. Copying of
any part of a program is cheating without explicit reference to its source. We
do enter lab assignments turned in by EE445L students through a plagiarism
checker, comparing them to assignments of this and previous semesters. 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. It is appropriate to use software out of the book, class website as
long as all copy-pasted software is explicitly referenced. Copy-pasting
software from current or past students is scholastic dishonesty. 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 the web.
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.
Request samples (DIP or PDIP package) The parts
labeled 1) 2)... 9) will be requested for you. In other words, we will make one
request for the entire class. However, keep these web sites in mind as you
design your Labs 8, 9,11. Do not order anything now; wait until you design
Lab 8, and then order what you need. You will need to register with an
official University email address (e.g., YourName@mail.utexas.edu) rather than
a junk email address (e.g., aol.com or gmail.com). For general information on
getting free samples, see http://www.ladyada.net/library/procure/samples.html.
