An in-depth look at the 8-bit AVR architecture found in ATtiny and ATmega microcontrollers, mainly from a software and programming point of view. Explore the AVR architecture using C and assembly language in Microchip Studio (formerly Atmel Studio) with ATtiny microcontrollers.

• Learn the details of how AVR microcontrollers work internally, including the internal registers and memory map of ATtiny devices.


• Program ATtiny microcontrollers using an Atmel-ICE programmer/debugger, or use a cheap hobby programmer, or even an Arduino Uno as a programmer.


• Most code examples can be run using the Microchip Studio AVR simulator.


• Learn to write programs for ATtiny microcontrollers in assembly language.


• See how assembly language is converted to machine code instructions by the assembler program.


• Find out how programs written in the C programming language end up as assembly language and finally as machine code instructions.


• Use the Microchip Studio debugger in combination with a hardware USB programmer/debugger to test assembly and C language programs, or use the Microchip Studio AVR simulator.


• DIP packaged ATtiny microcontrollers are used in this volume for easy use on electronic breadboards, targeting mainly the ATtiny13(A) and ATtiny25/45/85.


• Learn about instruction timing and clocks in AVR microcontrollers using ATtiny devices.


• Be on your way to becoming an AVR expert with advanced debugging and programming skills.
