基于ARM9的CNC系统USB-HOST驱动实现

摘要

以USB 1.1版本协议和OHCI 1.0版本协议为基础,开发了基于ARM9( EP9315)处理器的USB-HOST的驱动程序.该系统同时支持FAT16和FAT32文件系统,已成功应用于广州数控GSK928TEa及GSK928TCa的CNC系统,实现了工业化生产并推向市场.实践证明:该系统性能稳定可靠,通用性强,方便移植于其他平台.%This paper designed an USB-HOST drive program based on ARM9 micrprocessor EP9315 according to USB1.1 version and OHCI1.0 specification. This system supported FAT16 and FAT32 file system,and applied GSK928TEa and GSK928TCa CNC system successfully in GSK CNC EQUIPMENT CO. ,LTD. This CNC system was industrialized and put into production. Practice result proves that this system has stable and reliable performance,good generality,and can transplant to other platform conveniently.
