基于USB的数据采集及其在线缆通断测试系统中的应用

Data Acquisition with USB and its Application in Cable Switching Test

单片机通过USB跟PC机进行通信,单片机对命令和数据进行处理,配以PC机的直观形象的界面,可以很好地解决一个实际中的应用问题。从而完成线缆与51单片机的接口电路设计和USB接口电路设计,同时完成相应的软件设计以及显示界面的设计。

This article takes the design and implementation of cable switching test to introduce one use of the communications technology USB. SCM, which is equipped with the interface of PC, handles the orders and date by communicating with PC through USB. This article completes the circuit design of interface for 51 SCM and USB in addition to the corresponding software design and interface design.
