Preface

Marilyn Wolf, W2MCW Atlanta, Georgia

All computers need input and output to perform useful work. I/O systems are particularly important to embedded computers. While we may use standard devices in embedded systems, we often need to design specialized interfaces. Even when we do make use of standard devices, we need to be sure that the chosen interface meets the system’s requirements. This book is dedicated to the art, science, and craft of embedded system interfacing.

I built my own Heathkit radios: a GR-64 shortwave receiver, an HD-10 electronic keyer, and an HW-16 novice transceiver. My friend Art Witulski and I tried to build a switch-based adder; we gave up when we realized that our PCB patterning technology far outpaced our soldering ...
