摘　　要：随着嵌入式系统的发展,越来越多的嵌入式设备需要处理大量的数据,使用文件系统将成为这类嵌入式应用的一个必然趋势。本文基于Freescale公司MCF51QE128微控制器和SD卡,结合实验数据深入探讨了FAT16文件系统及其存储原则,实现了文件的创建、打开和多扇区数据的读写。With the development of embedded systems,more and more embedded devices need to deal with large amounts of data,and file system is an inevitable trend for embedded applications.Based on Freescale MCF51QE128 and SD card,FAT16 File system and its storage principles are described in combination with experimental data.Creating and opening files,as well as reading and writing of multi-sector data,are implemented.
