Textbook (Required):

• The AVR Microcontroller and Embedded Systems Using Assembly and C: Using Arduino Uno and Atmel Studio, 2nd Edition, by Sepehr Naimi, Sarmad Naimi and Muhammad Ali Mazidi, MicroDigitalEd, November 2017, ISBN-10: 0997925965, ISBN-13: 978-0997925968, http://www.microdigitaled.com/AVR/AVR_book_v2.htm

• Online-only parts of the book, tutorials and other material can be found on the publisher's website - http://www.microdigitaled.com/AVR/AVR_book_v2.htm as well as the author's website - https://nicerland.com/avr/

Integrated Development Environment (We'll use Microchip Studio):

• Microchip (formerly Atmel) Studio - https://www.microchip.com/en-us/development-tools-tools-and-software/microchip-studio-for-avr-and-sam-devices

• MPLAB X - https://www.microchip.com/en-us/development-tools-tools-and-software/mplab-x-ide

• Command line options are available for assembling/compiling and programming the microcontroller, but simulating, debugging and programming are simpler (and may be only available) with the IDEs

Assemblers/Compilers (We'll use AVR Assembler and one of the C compilers):

• AVR Assembler - https://ww1.microchip.com/downloads/en/devicedoc/40001917a.pdf - distributed with Microchip Studio

• MPLAB XC8 Assembler and Compiler - https://www.microchip.com/en-us/tools-resources/develop/mplab-xc-compilers - can be integrated with Microchip Studio and MPLAB X

• AVR GCC 8-bit Toolchain (Assembler and Compiler) - https://www.microchip.com/en-us/tools-resources/develop/microchip-studio/gcc-compilers - can be integrated with Microchip Studio and MPLAB X

Useful Links:

• ATmega328PB microcontroller's information (features, documentation, application notes, etc.) on Microchip's website - https://www.microchip.com/en-us/product/ATMEGA328PB

• ATmega328PB Xplained Mini evaluation kit's/board's information - https://www.microchip.com/en-us/development-tool/atmega328pb-xmini

Prerequisite: EE 271 (Mathematical Engineering)

Course Description: Introduction to microcontrollers. Topics include: programming in assembly and C, bus structures, interrupts, timing, real-time control, parallel and serial interfaces, support devices, disassemblers, and related topics.

Topics:

• Digital logic, terminology and numbering systems (binary, decimal, hexadecimal)

• Fundamentals of microcontrollers and microprocessors

• Architecture of AVR microcontrollers, and specifically the ATmega328 family

• Instruction set, assembly programming and the hex file

• Programming a chip and/or evaluation board

• C programming

• Digital Input/Output

• Timers

• Interrupts

• Input capture, wave generation and Pulse Width Modulation (PWM)

• Analog-to-digital converters (ADC)

• Serial Digital Communication via UART and Inter-Integrated Circuit (IIC or I²C)

Course Outcomes: Students will be able to

• read, interpret and use the AVR Instruction Set Manual and data sheets for the ATmega328 family of microcontrollers;

• develop, debug and simulate assembly and C programs for the AVR microcontroller in an Integrated Development Environment (IDE);

• program an evaluation board based upon the ATmega328 family of microcontrollers; and

• interface with a variety of peripherals.

Grading:

• Homework - 30% (working with others is encouraged so long as the work turned in is your own)

• Projects - 30% (guidance on whether projects are to be done individually or in teams will be provided)

• Exams - 40% (exams are to be done individually without external resources other than those specified)

• Assignments will typically be submitted via Canvas.

• Answers and supporting work must be written neatly and clearly.
