ECE3411: Microprocessor Applications Laboratory (Fall 2016)

Instructor: Marten van Dijk TA: Chenglu Jin

Course Introduction

The basis of sophisticated designs of modern digital systems that appear in products such as automobiles, appliances and industrial tools is the Micro Controller Unit (MCU); a microcomputer optimized for single-chip system design for controlling peripheral devices geared to real-time applications. We will use the Atmega328P microcontroller (from the Atmel MEGA series RISC microcontrollers) in a series of labs to design microcontroller based systems. In particular, we will explain how to read and use the Atmega328P datasheet and how to write self-explanatory C code for interfacing with the MCU and controlling peripheral devices. This includes initializing register values, writing Interrupt Service Routines (ISRs), constructing underlying Finite State Machines (FSMs), and using a task based programming approach based on hardware timers.

Throughout the course students will learn the basics of C (without advanced data structures that involve pointers) and learn how to use C to program a Micro Controller Unit (MCU). This class aims to educate engineering students with little coding background. I.e., as a prerequisite students are expected to have some experience with basic structures such as loops, if-else statements, arrays, etc. (e.g., as used in MATLAB).

This class offers an intermediary course which allows students to prepare themselves for MCU courses which expect students to have real experience with C, e.g., Bruce Land’s course at Cornell. Our goal is to use the new ECE 3431 class as a prerequisite to a to-be-developed advanced MCU applications lab where we will teach the topics including real time OS, networking protocols such as CAN bus and ZigBee, OLED displays, motor control applications and much more.

Accessing Instructor's Material

The links below provide the student view of all the taught material. If you are a colleague faculty member, you can email at marten.van_dijk@uconn.edu in order to get access to all the pptx, latex, and C source files together with all the solutions (which are omitted from the student view).
However, there is one catch: you need to acknowledge this course by adding (where appropriate) the following footnote to your slide decks:

Moreover, you need to suggest how the course can be improved and share with us the new quiz/final questions or lab problems as developed by you.

Student's Material

The links below provide all the lecture notes, labs and the class/lab quizzes. If you are a student following these lectures and want to get the solutions of the labs/quizzes, you can email at marten.van_dijk@uconn.edu to first show what code/solution you have attempted by yourself, and then get the complete solutions.

Preliminary Resources

Before coming to the first lecture/lab:

  • Place the order of your MCU kit and other components mentioned in the Online Ordering List.
  • Make sure to have set up Eclipse/GCC & Atmel Studio; see Tools Setup which explains how to do this for your laptop, you do not have time for installing software during lab!
  • Sign up for Piazza.

Your Fail/Pass the first QUIZ and TEST is a good indicator for being able to successfully complete this course!

  • Courses dropped after Monday September 12th will have a “W” for withdrawal recorded on the academic record.

From now on:

  • You will need to submit a lab report (not handwritten) each week Monday summarizing the preceding week's lab solutions (see syllabus)
  • Each lecture will start with a 5 minute short quiz/question about the reading assignment, posted lecture notes for that lecture, and previous lab.
  • During each lab we will step-wise present (and post at Piazza) solution slides in order to keep the whole class in sync: you will have time to first code up your own answers.
  • Highly Recommended: Write and maintain easy to understand template solutions yourself: This allows you to pick and choose code segments during lab tests.
  • Notice: The sample quizes and sample lab tests provided may not have 100 points.

We will provide a prediction of your final score based on the average of your last three quiz/lab test scores.

  • Monday October 31st is the last day to drop the course.

From now on:

  • We will not present any solution slides during lab: You will work on your own solutions during lab time and you can ask the instructor(s) questions and ask for explanations where needed.
  • From Lab6b onwards you are required to be even more independent: We will not lecture the new concepts, you will study the concepts with minimal guidance from the lab problem slides and you will extract information from the datasheet on your own.
