广泛使用MSP430为主控单元的穿戴式健康监护设备功能不断发展，促使在该平台下的数据实时存储和功能评测的需求日益增强。在此介绍基于MSP430的FatFs文件系统的移植以及Micro SD卡读/写功能的实现方法，提出了Micro SD卡读/写功能的评测方案，并测试了不同条件下的读/写速率。结果表明，FatFs文件系统能被灵活地移植到MSP430系统中，并能适应不同内存环境的应用需求，Micro SD卡的读/写速率与缓冲区大小直接相关。“,”The rapid development of wearable health care equipment,which takes MSP430 as its control core,results in an demand of data real?time storage and function evaluation increasingly. A method to transplant the file system FatFs based on MSP430 and realize the read?write function of Micro SD card is introduced in this paper. An evaluation approach for read?write function of Micro SD card is proposed. The read?write rates in different conditions were tested. The results show that the file sys?tem FatFs can be transplanted into MSP430 system flexibly,which is adaptable to the application requirements of different mem?ory environments,and the read?write rate of Micro SD card is directly related to buffer zone size.
