ECE 340/341 Microcontrollers and Lab (Fall 2016)

Policies

All assignments are collected at the start of class on the specified due date. Each assignment should have your name, the course number, the date, and the assignment designation (e.g., HW1, etc.). Attendance is mandatory. Students who miss five or more class periods will receive a final grade of F for the course. (Arriving late or leaving early is considered absent.)

Course Description

The primary goal of this course is to give you the fundamental skills needed to understand, use, and design microcontroller-based systems. This includes the following: (1) What is a microcontroller? (2) What can it do (and not do)? (3) How does one design (and program) a microcontroller-based system? Note: In addition to the listed prerequisites, ECE 340/341 required junior-level standing in EE or CompE. (e.g., You must have passed both Digital Logic and Circuits II with a C or better.)

Reading Assignments

Please complete the reading assignments in a timely manner so that you may contribute in the class discussions. The following abbreviations are used below, with # identifying the chapter or section: LD - Day # from the class text by Lucio Di Jasio; FRM - PIC32 Family Reference Manual (separate PDF file per section); DS - PIC32MX Datasheet (single PDF file); PLIB - PIC32 Peripheral Library Guide; MX - MPLAB X User Guide ; and XC - XC32 Compiler User Guide.

Homework and Quizzes (20%)

There will be homework and quizzes, possibly unannounced, throughout the semester. 

  1. Aug 26 - HW1
  2. Sep 2 - HW2
  3. Sep 26 - HW3
  4. Oct 24 - (1) What does the Digilent CerebotMX7 use as pull-ups on the I2C1 bus and why? (2) What do "A2, A1, and A0" refer to in Figure 5-2 of the EEPROM datasheet? (3)  Neatly sketch the SDA and SCL waveforms corresponding to writing of the control byte as shown in Figure 5-1.
  5. Oct 31 - Dr. J's Single Byte I2C Write & Read code used IdleI2C2() from the peripheral library, but he was elusive as to exactly what this function does. Using your skills to acquire new information please answer the following: (a) What does the Peripheral Library Guide say about this function? (b) What does the function comments say? and (c) What does the code actually do? (i.e., study the source code under C:\Program Files (x86)\Microchip\xc32\v1.31\pic32-libs\peripheral\i2c\legacy and explain the result)
  6. Oct 31 - Screen capture of I2C single byte write/read
  7. Nov 28 - For reach of the following PIC32 peripherals, determine if enabling the peripheral also configures the necessary I/O pins and cite the source of your information: UART, I2C, Output Compare, Input Capture.
  8. Nov 28 - Assume a timer frequency of 10 MHz and a measurement window of 10 ms. At what signal frequency does the "counting signal periods in a measurement window" method result in the same measurement resolution as the "measuring signal period using timer ticks" method?
  9. Dec 2 - Consider changing the specs for Lab 10 to use "Prescaled Capture Event" mode with a value of 16 rising edges before trigger: (a) How does this affect the resolution of your motor speed estimate? (b) How does this affect the range of motor speeds over which you can calculate a valid estimate?

    Exams (80%)

    Each exam is worth 100 points and will be closed book, closed notes. Semester exams are 50 minutes long; the final exam will be two hours long and comprehensive. Please bring paper, calculator, pencil(s) and eraser to the exam.

    Grading

    Grades (and other information) will be distributed electronically to student UI e-mail addresses periodically throughout the semester. Grades will be calculated using the traditional scale (90%=A, 80%=B, etc.).
