| But it didn't teach me any of the actual use of those protocols. That's not really the point of the book. Already having experience working with some of those protocols on my own, this chapter mainly provided a reinforcement of the availability and difference between so many serial protocols: their benefits and limitations, and things to consider as an engineer. | But it didn't teach me any of the actual use of those protocols.

| **Chapter Nine** takes us through getting ourselves into trouble and getting out of it again. It looks at debugging, at doing the basics first to solve an issue, problems that optimization can cause or mask, writing into memory that has fallen off a cliff, stack versus heap, registers and core dumps. | **Chapter Nine** takes us through getting ourselves into trouble and getting out of it again.

| - | Map files are explained - something I have never used before. These help give an understanding of the breakdown of an executable: the library space, how variables and functions are stored. Using this tool, all sorts of issues can be uncovered, and resource allocation can be greatly improved. | + | Map files are explained - something I have never used before.

| The safety of motors is covered and how you can add protection to your circuits.

| - | This is a great book. It's not going to hold your hand, and it's not a book of tutorials. It will, however, become your closest companion to help guide your own learning path, giving you valuable insight into what skills and experience will be valuable for a career in embedded systems. | + | This is a great book.

| - | I wouldn't call it a book for beginners. If you have been learning various aspects of embedded systems for some time then I think this is the sweet spot for this book to work well for you. | + | It acts as that friendly work mate who loves mentoring and who shares knowledge and experience. |
