电子测量设备USB数据采集系统设计

USB接口是目前数据通信中使用较多的接口类型,由于该接口支持设备热插拔而且传输速度特别快,所以很受欢迎.本文叙述了利用单片机AT89S52和USB接口芯片PDIUSBD12设计一个电子测量设备USB接口电路,可用作PC机和微处理机间传输数据的通路,以使PC机对各种设备进行控制.

Electronic measurement device USB data collection system design

USB interface is the most common type of interface used in data communication. Since this interface supports hot plug and pull and transmission speed is very fast, it is very popular. This paper describes the use of single-chip microcomputer AT89S52 and USB interface chip PDIUSBD12 USB interface circuit design an electronic measuring equipment, used for data transmission between PC and microprocessor pathway, to give the PC to control a variety of equipment.
