Unlike usual programming books, you won't be able to pick up the book, download something, and start working. You'll need to have an embedded system that you can use. The authors use a system from Arcom that will run you about $300. I've not used it and was very wary about it when I first started reading, but as I read through the various examples I gained a great appreciation for the system. It looks like a great way to gain hands-on experience with embedded programming.

Before getting this book I read through the Lego Mindstorm NXT documentation and felt very lost. I didn't understand the symbols on the schematics and they used strange acronyms (like I2C and PWM). I also have an Iguanaworks USB infrared transceiver. I bought it to use in a MythTV system I am building. This book has enabled me to understand the schematics of both the Mindstorm and the transceiver as well as the documentation of both systems. I now feel ready to do my own embedded systems programming.

That said, I did not like everything in this book. They gloss over areas that I felt would have helped me (such as how to use a JTAG adapter and how to create an interrupt service routine under Linux). There are areas where the writing does not flow well and is redundant. The book switched from using an embedded x86 processor in the first edition to using an ARM processor in the second and there are still references to the old processor.

Even with its faults I am glad I got this book. It filled in many of the gaps that I have as a software engineer who is wanting to learn about embedded systems programming. I feel a whole new world has just been opened up to me and I can't wait to jump in.
