摘要
介绍了USB接口协议。基于该协议采用PDIUSBD12器件和AT89S52微处理器组成的数据采集装置,该装置与PC机连接,在PC机中运行数据处理程序,显示信号波形。同时阐述了系统的总体设计思想及其层次结构,并给出了系统结构图。该系统采用USB总线传输数据,为数据采集系统与计算机之间的通讯提供新的思路。
Introduced the USB interface protocol. Based on the agreement with PDIUSBD12 device and AT89S52 microprocessor data acquisition device, the device is connected with the PC machine, PC machine running in a data processing program, display signal waveform. At the same time, elaborated the system design thought and its hierarchical structure, and presents the system structure diagram. The system uses the USB bus to transmit data, between data acquisition system and computer communications offer new ideas.
