摘　　要：介绍一种在嵌入式系统中基于SPI协议实现在SDHC上进行数据存储的方法。该方案以STM-32F407微处理器为主控制器,采用SPI总线通信方式,与SDHC卡之间进行数据通讯与存储。结合FATFS文件系统,可方便地实现数据的存储与导出,成功地解决了舰船天线日常使用数据量大、记录和保存困难的问题。A method of data storage on SDHC based on SPI protocol in embedded system is introduced, which makes STM32 F407 as the major controller, using SPI Bus communication mode, carries out the data communication and storage with SDHC card. Combining FATFS file system, it can easily realize the storage and export of the data, and successfully solve the problem of the large amount of data and the difficulties in the daily record and preservation of the ship antenna.
