Equipment to buy:

1) Board. Every student will be required to have a Texas Instruments TM4C123 LaunchPad by Friday 1/27. Since we will be using the TM4C123 kit in EE319K and EE445L for a few years, you will have the option of selling it at the end of the semester.  If you can find an EK-LM4F120XL board, it could also be used. Since it is only $13, we suggest each student purchase a board and a breadboard. Buying options for the board can be found by searching However, one option is to purchase it directly from . We have been using the TM4C123 board in EE319K since Fall 2013, so you might be able to find one used. If you do purchase a used microcontroller board, ask a TA or me to run the board tester to make sure all the pins work. If it still works at the end of the semester, you will be able to sell this board to students in the next semester.

2) LCD. Each group of two students will need to a LCD graphics display. We will be using Sitronix ST7735R 18-bit color 1.8" TFT LCD display for $20 plus shipping,   If you want a lower cost version you could order it from China (search ST7735R on Amazon or  ebay). EE445L has a design competition where students build embedded system. Using the same LCD for labs and for the project will save you time. Just like the microcontroller board, you will have the option of selling the Sitronix LCD to students next semester.
3) Breadboard. You will need a solderless breadboard. We strongly recommend you do not buy used or borrow a breadboard, because as the breadboards get old they fail in mysterious and extremely annoying ways (shorts and opens).  The Twin Industries TW-E40-1020 is a breadboard that is easy to find. You can find it for sale on the internet by searching :   Any breadboard, any size will be OK. Another approach is to search "solderless breadboard" on or
4) Wirestrippers and voltmeter. You will need own your own pair of wire-strippers and a digital multimeter. You will be stripping a lot of 22 or 24 gauge wire as you build the interface circuits. Your meter must be able to measure voltage and resistance, so a meter costing around $20 will suffice.  Since you will be making hundreds of solder joints this semester, we suggest you use the high-quality irons available on the second floor.  The NI MyDAC you bought in EE302 can be used for as the voltmeter.

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 :    
        50% Laboratory assignment with a large weight applied to Labs 7, 8 and 11
        15% Quiz 1, closed book (1-page crib notes), Friday, March 3 9:00 to 9:50 am, UTC 4.110
        15% Quiz 2, open book, Friday, April 21 9:00 to 9:50 am, UTC 4.110
        20% Final, closed (no crib notes)/open book, Thursday May 11, 2-5pm, ETC 2.108, regularly scheduled time and place
When studying, focus on the topics that apply to the ARM Cortex M 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 about 3.3).  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.  

Safety warnings: Due to the lead in most solder, please wash your hands after soldering, before eating or drinking. If you drop the soldering iron, let it fall to the ground. Do not try and catch it. If you are pregnant or think you might be pregnant, have someone else do the soldering.

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 1/23 to 1/26. 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 1/23 to 1/26. If you want to switch sections, there will be a googleDoc link on canvas, on which you can request a section swap. Basically, you will need another student (not your lab partner) with whom you will switch sections.

    During the week of 1/23, please go to your scheduled EE445L lab sessions in  ECJ1.318A to get a demonstration of the lab equipment.  If you do not already own a TM4C123 board, you must purchase one.  Each student should have their own board.  The lab preparations (hardware diagrams and syntax-free software source code printouts) must be uploaded to Canvas prior to the beginning of your lab period. PLEASE SEE YOUR TA ON EXACT REQUIREMENTS FOR TURNING IN LAB ASSIGNMENTS. 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. The uploading of preparations will close once Lab has begun. For the first 15 minutes of lab, 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 5, 2pm.

This is an approximate schedule, please check the website for the latest version.

Legal Stuff: The 12th class day is Feb 1. The drop policy is extremely complicated. See your academic advisor or the Dean of Students for more information. 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.

Religious Holy Days By UT Austin policy, you must notify me of your pending absence at least fourteen days prior to the date of observance of a religious holy day. If you must miss a class, an examination, a work assignment, or a project in order to observe a religious holy day, I will give you an opportunity to complete the missed work within a reasonable time after the absence. 

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.
The University Honor Code is "The core values of the University of Texas at Austin are learning, discovery, freedom, leadership, individual opportunity, and responsibility. Each member of the University is expected to uphold these values through integrity, honesty, trust, fairness, and respect toward peers and community."

The Digilent Analog Discovery is a low-cost but wonderful tool for this class. It is not required, but very handy, especially if you need to work at home this semester.

Software applications

To complete EE445L labs it will take time outside of the 3 scheduled lab hours. With the crowding we expect in ECJ, it will be important for you to configure a development system on your laptop (Keil version 4.7x, PuTTy, and PCB artist). This way you will be mobile and flexible about where and when you work on lab. For Keil 4.7x installation see . For PuTTY see . For PCB artist see 

Request samples (DIP or PDIP package) The parts labeled 1) 2) 3) 4) 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 7, 8, 11. You will order something as part of Lab 6.  Please order 2,3,4,5 now. Then wait until you design Lab 7, and then order what you need. You will need to register with an official University email address (e.g., rather than a junk email address (e.g., or For general information on getting free samples, see   Analog Devices

Emergency Preparedness and Emergency Plan Instructions
Please review
    Every member of the university community must take appropriate and deliberate action when an emergency
strikes a building, a portion of the campus, or entire campus community. Emergency preparedness means we
are all ready to act for our own safety and the safety of others during a crisis. It takes an effort by all of us to
create and sustain an effective emergency preparedness system. Your support is important to achieving the
best possible outcomes during a crisis event.
    As a University faculty member, you are responsible for pointing out your classrooms' building emergency
evacuation routes and for reviewing emergency procedures with students at the beginning of each semester.
This review should include a mention of the monthly emergency communications test (every first Wednesday
at 11:50 a.m.) and the list of communications channels the university uses during emergencies. It should also
include a review of the attached document outlining emergency terms (e.g., the difference between “shelter-inplace”
and “lockdown”) and instructions for faculty and students to follow during emergencies. As a matter of
convenience, we recommend including this information in your syllabus along with the phone number for the
Behavior Concerns Advice Line (BCAL: 512-232-5050). This is the number to call if you have concerns
regarding the attitude or actions of students, staff, or other faculty.
    Finally, at the end of your emergency preparedness review, request that students requiring assistance in
evacuation inform you in writing of their needs during the first week of class. This information must then be
provided to the Fire Prevention Services office by fax (512-232-2759), with "Attn. Mr. Roosevelt Easley" written
in the subject line.
    Thank you in advance for taking the time to ensure the safety of your classroom. I assure you this small effort
can yield much greater rewards should the unthinkable happen. If you would like more information regarding
emergency preparedness, visit
 Emergency Communications
Emergencies may range from inclement weather, to building evacuations, to campus closures, and the
university has a variety of tools to communicate with the public in the event of these and other possible
emergencies. Depending on the type of emergency, we may use some or all of the following tools to
communicate with faculty, staff and students:
Siren System
This system is tested around noon on the first Wednesday of every month, and delivers a siren warning
and public address in the event of certain outdoor emergencies. Read more about the siren system.
Emergency Web Site
You may want to bookmark the emergency Web site because it is updated with information during
actual emergencies or campus closures.
Local Press and Social Media
University Communications staff send emergency information to the press and update social media with
public safety messages. Because of the transient nature of our population, the university depends a great
deal on the press and social media to keep students, faculty, and staff informed during campus
Pager System
Our campus first responders, resident advisors, and some building managers are part of the AWACS
paging system. The pagers send text messages about emergencies on campus and alert city responders
(APD, AFD, EMS, Office of Emergency Management, etc.) to campus crisis situations.
Fire Panel Systems
Residence halls are equipped with fire panel systems that have a public address capability. Resident
advisors are trained to use these systems in emergencies in order to make announcements to the entire
building regarding evacuation, shelter in place, etc.
Text Alerts
The university collects cell phone numbers from members of the campus community for emergency text
messages. Sign up for campus text alerts online.
University Group E-mail
During emergencies, UT Safety Alert sends an “urgent” group e-mail to every student, faculty and staff
member. The e-mail directs individuals to the emergency Web site for additional information and
Voicemail to Office Telephones
This tool leaves a voice message on every faculty and staff member’s office phone on campus.
Cable TV
Residence halls and several of our public gathering places have cable televisions where emergency
announcements get posted.
Public Safety Patrol Car Announcements
UTPD patrol cars are equipped with PA systems, which officers can use to provide instructions to
pedestrians during emergencies.
University Emergency Information Line — 512-232-9999
Students, faculty, and staff can call this main number for information about campus closures.
The implementation of each tool described above is assigned to an individual who has at least two backups who can also
carry out the communications task. Individuals with electronic communication tools assigned to them have remote access
(from their homes, etc.) to those tools. The police department and the associate vice president for Campus Safety and
Security are typically the ones who deliver emergency information to university administration. Upon considering this
information, administration develops the messages and activates campus-wide communications. The only exceptions to
this are the sirens and pager system, which are activated directly by UTPD in extremely urgent situations where
immediate action is required.
