It's just what it say "a primer". This book seems like it would be great for someone who has never programmed for embedded systems. However, if you have even a few months experiance under your belt, this book is a big waste of time. I purchased this book to use a quick refresh after being away from embedded programming for a few years. Sent it back after reading about 25% and skimming the rest.
