    An Introduction to the Microcomputer, MC9S12C32 Architecture, The 6812 Instruction Set, 6812 Addressing Modes, 6812 Instructions, MC9S12C32 I/O and Memory Organization, The Memory Map of the MC9S12C32 
Programming Microprocessors (EE312, EE322C review)
    Data Structures in C (arrays, tables, linked lists, stacks, and fifo queues), Writing Quality Programs in C, Passing Parameters (Conceptual and Implementation Levels), Modular Programming, Verification and Testing, Documentation
Microcomputer Bus Interfaces
    Digital Hardware, Modules and Signals, Drivers, Registers, Timing equations, Timing diagrams, Address decoding, PROM, RAM interface
Parallel and Serial Input-Output
    MC9S12C32 Parallel I/O Devices,  Device Driver Software, Buffered Input and Output,  Table and Linked List Interpreters, MC9S12C32 Synchronous and Asynchronous Serial Input-Output, Synchronization in I/O devices, Blind-Cycle Synchronization, Busy-Wait Synchronization, Interrupt Synchronization, Polled Interrupts, Vectored Interrupts, Interrupt Priority
Parallel Port Interfaces
    Keyboards, Key Debouncing, Keyboard Scanning Techniques, LED Scanning Techniques and LCD Interfacing

After the successful conclusion of EE345L students should be able to design the hardware/software interface for devices 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 :    
        35% Laboratory
        5% Weekly multiple-choice online homework
        15% Quiz1, closed book, Friday, October 19, 1:00 to 1:50 pm, regular classroom
        15% Quiz2, open book, Friday, November 16, 1:00 to 1:50 pm, ART 1.102
        30% Final, closed/open book, Friday, December 14, 9am-12noon, regularly scheduled
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 (Pick-A-Prof 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 1/23 to 1/27. 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.
Laboratories 
  Lab 1d. ASCII to fixed-point conversions (signed 0.01)
  Lab 2g. Debugging, dump profile
  Lab 3f. Alarm clock, LCD and Output Compare interrupts
  Lab 4h. Stepper motor, output compare interrupts, finite state machine
  Lab 5g. 12-bit DAC, SPI

  Lab 12a. Final Design and Evaluation of 6811 Embedded System
  
EE345L 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 EE345L TA is authorized to checkout your lab.  Please consult with your TA for specific due dates for your lab section.
 

New Schedule

"8 Demo" means your final ExpressPCB file is delivered to the TA
 

Old Schedule

Prep = you turn in your lab preparation
Demo = you demonstrate your lab to the TA
Partial = you demonstrate first part of a two-week lab to the TA
Report = you turn in your complete lab report to the TA
    During the week of September 4-6, please go to your scheduled EE345L lab sessions in ENS252C to get a demonstration of the lab equipment.  If you did not get a TechArts 9S12C32 kit in EE319K, then a kit will be given to you. Each student will get exactly one kit. If you loose it or destroy it, you can purchase another from Technological Arts for $50 plus shipping. For more information on purchasing a replacement kit, go to the http://www.technologicalarts.com/  web site and click the University of Texas at Austin link (order NC12C32SP). Lab partners will be selected in your lab the week of September 4-6. The Lab 1 preparation is due at the beginning of your lab the week of September 10 or 11.  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 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 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 5, 5pm.

 

Legal Stuff: The 12th class day is September 14. 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 extremely uncivilized 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.
When studying, focus on the topics that apply to the 9S12C32 and the lab assignments.  You will find old quizzes and finals with solutions on the class web site.
