摘要
USB Host器件CH378内置了USB通信协议栈和文件系统,并提供多种操作命令,能够方便地与多种处理器进行接口。基于CH378和ARM处理器LPC2138,设计了一种新颖的实时数据记录仪,支持FAT32文件系统,可将现场采集的各种实时数据及时保存到U盘之中,利用U盘的大容量和良好移动性,可方便地实现与计算机进行数据交换,达到现场数据采集、室内数据分析的目的。
USB Host device CH378 is built with USB communication protocol stack and file system,which provides a variety of operation commands.It can be easily interfaced with a variety of processors.A new type USB Flash disk multi-parameter recorder is designed based on CH378 and LPC2138 ARM microcontroller,it supports FAT132 file system,and can be used for mass-data acquiring.All kinds of real-time data collected on site can be saved to U disk in time.Using the large capacity and good mobility of the U disk,the data exchange with computer can be easily realized,so as to achieves the purpose of field data acquisition and indoor data analysis.
