摘要
本文介绍了一种基于USB总线的数据采集系统的设计方案和开发方法。该系统由Philips公司的PDIUSBD12芯片及89C58微控制器等组成。文中,介绍了PDIUSBD12芯片的性能和特点及与MCU的接口电路,阐述了程序的总体设计思想及其层次结构,并给出了主程序流程图。使用USB总线传输数据,为数据采集系统与计算机之间的通讯开辟了新的道路。
The design scheme and developing method of a suit of data acquisition system which is based on USB bus used with Philips' PDIUSBD12 and MCU of 89C58 are expatiated. In the paper, the performance of PDIUSBD12 and the interface circuit to MCU are described ,then shows the idea of program design and hierarchy, the flow chart of main processing program is also given. Using USB bus to transfer data blazed a way in communication between data acquisition system and computer.
