Résumé
"I sincerely wish (this book) had been available when I had to learn all this stuff the hard way."
Steve Vinoski
"An excellent job of introducing and defining the jargon associated with embedded systems.This makes the text extremely easy to read."
David Cuka
An Embedded Software Primer is a clearly written, insightful manual for engineers interested in writing embedded-system software. The example-driven approach puts you on a fast track to understanding embedded system programming and applying what you learn to your projects. This book will give you the necessary foundation to work confidently in this field.
Building on a basic knowledge of computer programming concepts, this book will help you to:
- Learn core principles and advanced techniques of embedded-system software
- Find out what a real-time operating system (RTOS) does and how to use one effectively
- Experiment with sample code and the ?C/OS RTOS version 1.11 (on the accompanying CD)
- Apply what you learn, no matter which microprocessor or RTOS you use.
After reading this book, you will be able to tackle the
challenges of embedded system programming and quickly reap
the benefits of your new skills.
