Preface In 2006 Morgan & Claypool Publishers (M&C) released the textbook, titled “Microcontrollers Fundamentals for Engineers and Scientists.” The purpose of the textbook was to provide practicing scientists and engineers with a tutorial on the fundamental concepts and the use of microcontrollers. The textbook presented the fundamental concepts common to all microcontrollers. This book was followed in 2008 with “Atmel AVR Microcontroller Primer: Programming and Interfacing.” The goal for writing this follow-on book was to provide details on a specific microcontroller family – the Atmel AVR Microcontroller.This book is the third in the series. In it the emphasis is on system level design and advanced microcontroller interfacing and programming concepts. Detailed examples are provided throughout the text. APPROACH OF THE BOOK We assume the reader is already familiar with the Atmel AVR microcontroller line. If this is not the case, we highly recommend a first read of “Atmel AVR Microcontroller Primer: Programming and Interfacing.” Although some of the content from this earlier volume is retained in this current book for completeness, the reader will be much better served with a prior solid background in the Atmel AVR microcontroller family. Chapter 1 contains an overview of embedded systems level design. Chapter 2 presents a brief review of the Atmel AVR subsystem capabilities and features. Chapters 3 through 7 provide the reader with a detailed treatment of the subsystems aboard the AVR microcontroller. Chapter 8 ties together the entire book with several examples of system level design. Steven F. Barrett October 2009
