基于STM32F107VCT6微控制器，在μC/OS-Ⅲ系统下针对U盘与SD卡之间的文件传输进行研究。控制器分别通过SPI串行总线和OTG接口与SD卡和U盘实现数据传输，控制系统通过FATFS文件系统将U盘的文件数据存入控制器的缓存之中，再将数据写入SD卡，实现了U盘与SD卡之间的数据传输。实验表明：该文件传输原理简单、功能稳定，可广泛应用于日常生活和工农业的小型嵌入式设备当中。

The file transmission between U disk and SD card in the μC/OS-Ⅲsystem based on STM32F107VCT6 chip is studied in this paper. The controller achieves data transmission by SD card and U disk respectively through SPI serial bus and USB OTG interface. The control system saves the file data of U disk into the cache of controller itself by FATFS file system, and then writes the data into the SD card to realize the data transmission between USB and SD card. The file communication mode is simple and stable,and can be widely applied to small embedded devices used in daily life,agriculture and industry.
