Imagine a world where your heater is hooked up to your cell phone! Or perhaps an email is sent to you from an embedded sensor within your air conditioner to remind you that you need to change the filter. The possibilities make your head spin, but those are examples of what embedded systems can do for you if they are linked to the Internet. But, there is a lot to learn about the processors that can get your devices Internet enabled, and this book will take you there.
Author Al Williams does an excellent job of creating for you an Internet-enabled system that requires a blend of skills beyond the traditional hardware skills. Embedded Internet Design is divided into three different sections. In the first section, you'll find valuable background information, a quick introduction to Java, and some Java software that can turn an ordinary PC (or other desktop computer) into a bridge for any RS-232-capable (Recommended Standard 232, computer serial interface, Institute of Electrical & Electronics Engineers [IEEE]) microcontroller. The second section focuses on the Maxim/Dallas Semiconductor Tiny Internet Interface (TINI), which is a small, Java-based microcontroller with impressive networking capabilities. The third section shows you how to use the Parallax Javelin (a small controller that runs a variation of Java) with different types of modems.
The future is wide open on embedded systems. It is almost impossible to imagine all the ways in which this technology will change our lives. For those of you whose job it is to not only imagine these systems but to develop them, this outstanding book is a much-needed tool. John Vacca
