This book introduces embedded systems to C and C++ programmers. Topics include testing memory devices, writing and erasing Flash memory, verifying nonvolatile memory contents, controlling on-chip peripherals, device driver design and implementation, optimizing embedded code for size and speed, and making the most of C++ without a performance penalty.

Embedded software is in almost every electronic device in use today. There is software hidden away inside our watches, VCRs, cellular phones, and even a few toasters. The military uses embedded software to guide missiles and detect enemy aircraft. And communication satellites, deep-space probes, and many medical instruments would've been nearly impossible to create without it.

Someone has to write all that software, and there are tens of thousands of electrical engineers, computer scientists, and other professionals who actually do. I am one of them, and I know from my personal experience just how hard it can be to learn the craft. There aren't any embedded software courses in school, and I've never been able to find a decent book about the subject in any library.

Each embedded system is unique, and the hardware is highly specialized to the application domain. As a result, embedded systems programming can be a widely varying experience and can take years to master. However, one common denominator across almost all embedded software development is the use of the C programming language. This book will teach you how to use C and its descendent C++ in any embedded system.
