摘要
数据采集技术是一门综合应用技术,主要研究信息数据的采集、存储、处理以及控制等,具有很强的实用性。USB技术以其支持热插拔和即插即用、占用系统资源少等特点迅速得到广泛应用。USB2.0凭借其480Mbps的理论传输速度,更是得到了人们的青睐。结合当前国内外USB接口技术的研究现状,深入研究了USB的体系结构。硬件部分具体描述了USB2.0单片机C8051F340的接口设计。在软件部分,使用Cygna VSilicon公司的USBXpress软件开发包,该开发包针对C8051F340等器件的USB接口编程设计,提供了完整的上位机与下位机软件解决方案。其中上位机客户应用程序是与用户交互的一个窗口,用于完成接收并显示从硬件传递过来的数据。
Data acquisition,as an integrated application technology,mainly focuses on information data acquisition,storage,processing and control and has a strong practicability.With such features as hot -swappable,plug and play,less system resource occupancy,etc.,USB technology has been rapidly and widely used.USB2.0 is used due to its fast theoretical transfer speed of 480Mbps.Combined with latest development of USB interface of both interior of country and abroad,the USB architecture is deeply studied.The interface design of C8051F340 microcontroller USB 2.0 is described for the hardware. USBXpress software development kit,from CygnaVSilicon,is used for the software,which conducts USB interface program design for devices such as C8051F340 to provide a complete software solution for both upper and lower computers.APP of upper computer,as a way of communication with customers,is used to accept and present data of hardware.
