| 摘 要： | 系统基于高集成度、低功耗的MSP430F1611单片机,利用SPI总线与SD卡通信。在单片机RAM较小的情况下,平衡SD卡存储速度、所需RAM以及系统功耗,设计优化的FAT16文件系统,实现对SD卡的数据写入。将该设计应用于便携式心电监护仪上,完全满足48h 256Hz心电采样时间和频率的要求,实现了对心电数据的实时保存。

| Abstract: | The presented system, based on high-intergration, low-power SCM MSP430F1611, realized communication by SD card and SPI bus.Under the situation of lack of RAM ,the design balanced storage rate of SD card, RAM and system power, established optimized FAT16 file system in SD card which realized the storage of data.The design was used on portable ECG monitor very well which required 48 hours record and 256 Hz sampling frequency. |
