基于ARM9的数据采集与传送系统设计

以S3C2440微处理器为核心,充分利用其内部资源,如串口控制模块、GPIO等,发挥ARM处理器高性能、低功耗、低成本的优点,并利用其扩展接口(GPIO)结合AD7466模数转换芯片,实现了对模拟信号和脉冲信号的数据采集.同时,为了达到良好的人机交互界面,设计了以S3C2440为核心下位机的LCD接口以及网络数据传输模块,并对相关硬件驱动的程序设计流程作了说明.

System Design for Data Collection and Transfer Based on ARM9

Taking S3C2440 microprocessor as the core,making full advantage of its internal resources,such as the serial port control module,GPIO,etc.,bringing merits of ARM processor into play,such as high performance,low power,low cost and using its expand interface（GPIO） combined with AD7466 analog-to-digital conversion chip,the analog signal and pulse signal data acquisition were realized.Meanwhile,in order to achieve a good man-machine interface,LCD interface taking S3C2440 as the core and network data transmission module were designed.
