Applied Research of the Inner Timer of General Microcomputel in High-Speed and Real-Time Data Acquisition System

摘要

The real-time data acquisition system controlled by microcomputer is applied widely. It is very important how to use the inner timer of microcomputer to realize accurate timing of sampling-interval in the appli- cation of data acquisition. This paper discusses in detail the procedure that we use the inner timer of mi- crocomputer to realize real-time data acquisition with high timing-accuracy, and analyze the error of timing-accuracy. It also gives us a relevant routine programmed in assembly language.
