本资料包括建立在SD卡和NANDFLASH上的文件系统，具体如下： SD卡：FAT32 NANDFLASH：FAT16 SD&NAND：整合的文件系统，SD(FAT32)的盘符是"ide",NANDFLASH(FAT16)的盘符是"FLASH" uc/FS基本使用方法: 1. FS_Init(),在调用uc/FS功能前需要进行初始化 2. FS_IoCtl(),对媒质进行格式化(SD卡用电脑格式化,所以未给出格式化参数) 3. _write_file, 1)FS_FOpen(),建立文件或打开已有文件,返回文件结构指针 2)FS_FWrite(),数据写入文件 3)FS_FClose(),关闭文件 4. _dump_file,1)1)FS_FOpen(),建立文件或打开已有文件,返回文件结构指针 2)FS_FRead(),读出文件数据 3)FS_FClose(),关闭文件 5. FS_Exit(),关闭文件系统. 具体文件系统应用接口见fs_api.h
