Course Objectives

 

 

By the end of the course the student will be able to explain and apply the following:

 

1.     The characteristics of a microcontroller, its applications and how it compares to a microprocessor.

 

2.     The relationship between hardware and software and how they work together to accomplish a task.

 

3.     How digital building blocks (such as ALU, memory, multiplexers, decoders) work together in a microcontroller.

 

4.     Interfacing to the mostly analog outside world making use of timers, input capture/output compare, PWM, A/D, serial and parallel ports and interrupts.

 

5.     An Integrated Development Environment, an Evaluation Board, and various other tools for project design, troubleshooting and debugging.

 

6.     Analysis of a given flow chart and hardware schematic to deduce operation and functions of a microcontroller/embedded system.

 

7.     Synthesis of a microcontroller/embedded system from a real-life problem statement.

Laboratory Exercises

 

Objectives of Laboratory Exercises

 

  1. Become familiar with firmware/software and hardware covered in this course. Given a program, enter, assemble, download, and run that program on an HCS12 microcontroller based evaluation board. Write a modified version of the given program and assemble/debug/download/run the program.

     
  2. Write and run a binary count assembly language program and a “chaser light” assembly language program. The 8 LEDs on the Dragon12 are used for displaying the count and the chaser light. A timing delay using a loop within a subroutine is used in both programs.

 

Possibly one or more of the following:

 

  1. Develop a simple alarm system making use of switches for modes, push buttons for windows, LEDs for status, and the speaker for sounding an alarm.

     
  2. Using a multiplexing technique, display the student’s birthday on a quad 7-segment display using the format: mm dd and then the year in four digits.

     
  3. Making use of A/D to develop a simple digital voltmeter.

     
  4. Revise  # 5 by using ‘C’ programming and the LCD display.

     

Operations in the Lab

 

The class will be divided into groups of three students. For each laboratory exercise the three students will be assigned as follows:
          1. the pre-lab person is responsible for assuring the pre-lab work is complete and communicates with group and instructor up to the actual lab day

          2. the facilitator makes sure the time is spent productively in lab itself keeping everyone on task

          3. the spokesperson/recorder interacts with instructor and other groups and makes sure all important results and problems are recorded in a notebook (which each group maintains through the semester and which is signed by the group members and the instructor each week)

 

NOTE: Regardless of each student’s assignment, everyone is responsible to know and understand what is going on with a particular lab exercise. It is hoped that these lab groups will also evolve into study groups, which have been shown to help students improve their learning.
