Interfacing Microcomputers for Control and Data Acquisition

Abstract

The use of microprocessors for control and data acquisition requires interfacing the microprocessor with the unit or process to be controlled or sampled. To effectively interface, the engineer must understand the microprocessor signals, their timing, and interfacing techniques. In this tutorial article, coverage of these topics is provided. Specific examples of address decoding, and analog and digital input and output circuits are included. A knowledge of the material presented in the earlier articles in this series is assumed.
