Description: 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-本资料包括建立在SD卡和NANDFLASH上的文件系统，具体如下：
