Course
Objective:
Provide students
with the opportunity to gain experience in microprocessor-based
system design, assembly language programming, and I/O interfacing
to microprocessors.
Course
Outline:
The course
is broken into individual labs which will illustrate the principles
covered in the lecture section of CPE 301. Each student
will design, build, test and troubleshoot (if necessary) interface
circuits to an 8051 based Single Board Computer (SBC) and write
programs to execute on the same SBC.
Course
Format:
Show up ready
to work. You should be comfortable with the material and
know how to complete the lab objectives. If schematic diagrams
are required, have them ready. If you will be required to
design a given circuit, thoroughly understand the fundamentals
involved in the design, and be ready to sit down and design it.
Have questions ready for the current week's lab, and if you feel
uncomfortable about the next following week's material, talk with
the lab instructor or the lecture instructor before the next lab.
At the beginning of each lab session there will be a brief discussion
covering details specific to that lab and to answer any questions
you might have. The bulk of the three hour period is for the lab
work.
This is a
hands-on course and each student must build his or her own circuits
and write his or her own programs. Circuit parts will be provided,
but you are expected to have your own basic tools to assemble
them. The following tools will be needed and must be purchased
by each student:
-JE24 Breadboard
-JE10 Wire
Jumper Kit
-wire cutters
or heavy scissors
-3.5 Floppy
disks (1 or 2 are recommended) or Thumb Drive or CD-R/W
-Lab Notebook
-Read the
Safety Issues and Guidelines document
at the end of this syllabus and answer all questions on the safety
quiz.
-Your
completed safety quiz will be collected at the beginning of the
first Lab session.
Each student
must purchase and maintain a lab notebook. The lab instructor
will ask to review your lab notebook each lab session.
The exact type of notebook is unimportant, but the pages must
be permanently bound. The lab notebook should be used to record
your laboratory experiences, observations, setup details, and
anything else that occurs. The Lab handouts should be kept in
a loose leaf binder to accompany your lab notebook. The
notebook should provide a permanent, chronological record of lab
work and analysis. The use of such lab notebooks is required
by most companies as a way of documenting "intellectual property"
and providing legal proof of when something occurred. It's
also a very GOOD habit to develop.
At the end of each lab section all work
will be cleared from the computer. The lab computers include
floppy drives, CD burners, USB ports, and an internet connection.
It is highly recommended that these devices be used to regularly
back up your work.
Grading:
Each student
must build his or her own circuits and write his or her own programs.
The resulting circuits or programs must then be demonstrated to
one of the course instructors in order to obtain a grade for each
lab. The instructors will also examine each student's lab
notebook and ask questions to make sure each student understands
the completed work. The completeness of the notebook and
answers to questions will affect the grade. Formal lab reports
will not be required.
The demonstration
of each lab should be completed during the current lab session,
however if this is not possible the demonstration must be completed
before the next following lab begins. This means that if
you cannot complete your lab work during the 3 hour lab period
you can still complete it outside of lab time and demonstrate
it, during posted office hours, before the next lab period.
The laboratory room is available to students anytime the building
is open. The lab door has a combination lock and the combination
will be provided to students.

Labs will
be graded from 0 - 100 points based on correctness and completeness,
notebooks, and answers to questions. Each unexcused lab
absence will reduce your Lab grade by 5% and more than 3 will
cause you to automatically fail the lab.
Students
must pass both the lecture and lab components of this course independently
in order to pass the course. Assuming you have a passing
grade in both the lecture and lab then your course grade will
be calculated as defined in the lecture syllabus.
If you have
a disability for which you will need to request accommodations,
please contact one of the instructors or Mary Zabel at the Disability
Resource Center (Thompson Student Services - 107), as soon as
possible to arrange for appropriate accommodations.
After reading this material, please
answer the attached questions, sign and return the last page at
the beginning of your first Lab session.
Introduction:
The CPE 301 class, working in the IGT Computer Engineering Lab (323 SEM), requires the use of many electrical and mechanical devices. The improper use of this equipment can present serious hazards to human health. The purpose of this paper is to address safety issues and minimize danger in the lab.
More material on safety is available in the laboratory. This handout is required reading.
After reading this material, please
answer the attached questions, sign and return the last page at
the beginning of your first Lab session.
Students Rights and Responsibilities:
All safety programs have the unwavering support of the faculty and staff. Each person in the lab is responsible for the safety of every other person in the laboratory. Each student should feel free to correct each other and point out any safety deficiencies in the lab. Students have the right and the responsibility to identify unsafe actions, procedures or conditions without jeopardizing their grade.
Electrical Hazards:
Electricity is the most dangerous component of this lab. Electrical shock can cause serious injuries and even death. Low voltage does not imply low hazard. It only takes 50mA of current to KILL you. Therefore the following precautions should be implemented:
- When working on a circuit, disconnect the power.
- When troubleshooting, place one hand behind
your back or in a pocket.
The most dangerous
current path is through the chest.
Current enters
one hand, flows through the chest, and exits through the other.
- Remove jewelry when working with electronics.
- Wear rubber soled shoes.
- Do not tamper with electrical outlets and do not plug or unplug equipment.
- Use the fixed 5V supply and check to make sure that it is 5 volts.
- Capacitors can stay charged for long periods of time. Discharge them (safely) before working on a circuit.
- Do not work in the lab alone.
- Polarized capacitors can explode if the voltage is reversed. Make sure they are properly connected.
- Keep your hands dry.
- No food or drink in the lab.
- Know how to shut power off to a piece of equipment.
- If you do not know how to operate a piece of equipment, DON'T.
If you have any questions, ask. If you see any unsafe conditions, tell me or some other faculty member.
Mechanical Hazards:
Do not move any equipment in the lab. Lots of the equipment in the lab is heavy and can cause injuries when dropped.
Basic Rules:
- Keep all tools in good condition.
- Use the right tool for the job.
- Examine each tool before use.
- Operate tools only according to the manufacturer's instructions.
- Keep workspace clean.
Thermal Hazards:
Soldering irons may be used for assembling the projects. The soldering iron can produce temperatures above 800° F and can cause severe burns. Caution must be exercised when using soldering irons. If you do not know how to operate the irons, consult the lab instructor. Unplug all soldering irons when finished.
Integrated circuits can become very hot if they are improperly energized. They can get hot enough to cause burns. Check your circuit for reversed polarity before you apply electrical power.
UV Hazards:
EPROM erasers use ultra-violet light to erase EPROMs. When the drawer is opened, the lamp should turn off. However, use caution when using these devices and do not tamper with them. Erasers should be unplugged when not in use.
Chemical Hazards:
This lab may require soldering and therefore, the use of solder. The following is a list of toxins in solder: Lead, Tin, Silver, Bismuth, Antimony, Copper, and Indium. Ingestion and inhalation of solder smoke can affect kidneys, gastrointestinal, reproductive and neurological systems.
Solder is not explosive and is very stable. Do not melt solder above 1000° F. This will liberate highly toxic lead and antimony fumes.
Precautions:
- Store away from sulfur.
- Wash hands before eating or smoking.
- Avoid breathing fumes.
- Use of strong acids may result in liberation of toxic lead chloride fumes.
- Use of goggles is suggested.
General Safety Rules:
- "Horseplay" is hazardous and will not be tolerated.
- No student will work alone.
- No loose clothing, especially at the drill press.
- Worn or frayed power cords or those with broken connections must not be used.
- All aisles and exits must remain clear and unblocked.
- The instructions on all warning signs must be read and obeyed.
- Keep area clean.
- Eating, drinking, tobacco products and application of makeup are prohibited.
- All injuries, accidents and "near misses" must be reported.
Quiz Questions:
1. When troubleshooting a "live" circuit, where should your hand(s) be?
2. What current level is needed to produce death?
3. Before applying electrical power to your circuit, what should you check for to avoid burning chips?
4. Why shouldn’t you melt solder above 1000° F?
5. What should be done with the EPROM erasers when they’re not in use?
