摘要
目前USB接口得到了广泛的应用,本文设计了一个开放灵活的基于USB通信的电机控制实验系统,采用PDIUSBD12作为USB接口芯片,以单片机AT89C52和计算机主机进行数据通信,实现了USB通信模式的实时模拟数据采集、步进电机控制和数字接口扩展设计,为学生提供了便利的软硬件实验平台,并可以自行组合或开发多种实验项目。
The USB interface is widely used at present. In this article an open and flexible USB communication experiment system is designed. PDIUSBD12 as the USB interface is used, while the data correspondence is between AT89C52 and host computer. The real - time analog data acquisition, step motor control and the design of numeral interface expand have been carried out in this system, which provide a convenient experiment system based on the software and hardware, by which various experiments can be developed and combined by themselves.
