摘要
考虑到嵌入式系统的数据保存和数据移动的需要,本文设计了一种采用FAT文件系统进行存储的软硬件实现方案。在采用S3C2440微处理器的硬件平台和μC/OS-Ⅱ嵌入式实时操作系统的基础上,设计基于SDIO接口的SD卡硬件解决方案,重点研究了标准SD卡和SDHC卡的驱动,并移植FatFs文件系统模块。实际应用表明,该数据存储系统满足设计要求,运行稳定可靠,具有良好的通用性和扩展性。
Considering the needs of data storage and data movement for the embedded system,this paper designs the software and hardware implementations that use the FAT file system for storage.On this basis ofthe S3C2440 microprocessor hardware platform and μC/OS-Ⅱ embedded real-time operating system,the paper designs the SD card hardware solution with the SDIO interface,focuses on the standard SD card and SDHC card driver,and transplants the FatFs file system module.The practical application shows that the data storage system meets the design requirements,stable and reliable,with good versatility and scalability.
