A Few Words about Hardware

It is the nature of programming that books about the subject must include examples. Typically, these examples are selected so that they can be easily experimented with by interested readers. That means readers must have access to the very same software development tools and hardware platforms used by the author. Unfortunately, in the case of embedded programming, this is unrealistic. It simply does not make sense to run any of the example programs on the platforms available to most readers—PCs, Macs, and Unix workstations. Even selecting a standard embedded platform is difficult. As you have already learned, there is no such thing as a "typical" embedded system. Whatever hardware is selected, the majority of readers will not have access to it. But despite this rather significant problem, I do feel it is important to select a reference hardware platform for use in the examples. In so doing, I hope to make the examples consistent and, thus, the entire discussion more clear.
