摘要
考虑到某些特殊环境对采集电路体积的限制,提出了一种基于SST25VF032B的小体积数据采集存储系统设计方案,通过CPLD控制A/D转换器及Flash实现数据的采集及存储,数据的读取、显示及擦除可由VB软件编程来实现。并详细分析了该串行Flash在实际数据采集存储电路中的应用。该系统的尺寸为20.5 mm×14.5 mm,能很好的满足小体积的要求,且较适合于低频采集。
Due to limitations of the sampling circuit volume in some special environment,this paper proposed the design scheme of a data sampling and storage system of smaller size based on SST25VF032B,using the CPLD controlled the AfD converter and the Flash to achieve data sampling and storage, while data access,display and erasing can be achieved by programming the VB software.And the application of SST Flash in the actual data sampling circuit was analyzed in detailed.The size of this system is 20.5mm×14.5mm,meets small volume request,and it is better for sampling of low frequency.
