摘　　要：Compact Flash(简称CF卡)是一种应用空间广阔,成本低的存储设备。介绍了SEP3203嵌入式处理器和CF卡的接口电路,CF卡的工作原理以及CF卡的驱动程序。FAT文件系统在嵌入式系统中应用越来越广泛,传统的8.3格式文件名已经满足不了某些应用的需求。介绍了短文件名和长文件名之间的差异,分析了支持长文件名的数据结构,以CF为存储介质设计和实现了FAT16文件系统,这一文件系统支持长文件名文件的读写操作,有效地解决了嵌入式环境下使用长文件名所存在的问题。CompactFlash （CF card） is a broad application of space,low -cost storage devices. Introduces the SEP3203 embedded processor ,and the CF card interface circuit, the working principle of CF card and CF card drivers. FAT file system in embedded system applications become wider, the traditional 8.3 fore,at who had failed to meet the needs of certain applications. Discusses the short and long file name of the differences between the documents, analysis of the long file name support data structure to CF storage medium for the design and realization of the FAT16 file system, file system that supports long file names and write to files,an effective solution embedded environment by the use of long file name the problems.
