An Embedded Software Primer
"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 µC/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.
Why Read This Book
You will learn pragmatic techniques for writing reliable, maintainable embedded firmware—how to structure code, handle interrupts, manage timing, and interface with hardware. The book gives hands-on advice and debugging strategies that shorten the learning curve when you move DSP algorithms from desktop prototype to MCU/SoC target.
Who Will Benefit
Firmware engineers, systems engineers, and DSP practitioners who need to implement or integrate signal-processing code on embedded microcontrollers or processors.
Level: Intermediate — Prerequisites: Basic C programming and familiarity with digital electronics or microcontroller basics; familiarity with compilation and build concepts is helpful.

How It Compares
Covers practical embedded-software topics similarly to Michael Pont's Embedded C books but is broader in systems-level advice and more focused on fundamentals than Valvano's ARM-specific texts.
