FATFS官方库使用SPI底层接口控制，STM32处理器-FATFS official library uses underlying SPI interface control, STM32 processor

在STM32103FZET6跑上系统，用SDIO方式与SD卡通信，有FATFS文件系统。-In STM32103ZET6 ran system, using SPI way SD card communication, there FATFS file system.

SPI FLASH专用文件系统，具备磨损均衡算法，如果是本地数据强烈建议使用该文件系统而不是FATFS(SPI FLASH dedicated file system, with a wear balance algorithm, if local data is strongly recommended to use the file system instead of FATFS)
