Universal Microcomputer Interface for Data Acquisition.

Abstract

A Universal Interface Device (UID) was constructed for the TRS-80 Model I microcomputer that enables it to perform a wide variety of digital and analog data acquisition and control fucntions within the Department of Aeronautics. The system was tested and validated for low frequency data acquisition and control in a wind tunnel experiment and higher frequency applications were predicted with the development of additional software. The UID consists of a collection of off the shelf and author designed components assembled within a common enclosure to provide eight channels of analog to digital input, a single channel of digital to analog output, eight bit TTL level digital to digital input and output, and eight power relay outputs all under software control of the host microcomputer. Applications software, calibration tables, and a validation experiment were prepared and included within the appendices. The UID produced results within one percent of manual observations. (Author)
