摘要
提出一种基于串行接口的单片机通用数据采集系统,该系统以AT89S52单片机为核心,从数据采集、存储,与上位机通信到数据显示全部采用串行接口器件,降低了布线密度,提高了系统可靠性。详细介绍系统硬件组成,尤其实时时钟日历器件SD2001E,并给出了软件设计流程图。
A multi-channel general data acquisition system based on AT89S52 is introduced.The system can be used in data acquisition,data store ,communication and demonstration.All of there use serial interface components.So it can reduce the wiring density and enhance the system reliability.The system hardware structure and real-time clock SD2001E are introduced in detail,and the software flow is given.
