一种U盘存储的数据采集系统的设计

The design of a data acquisition system based on U-disk memory

系统在微处理器ATmega32控制下,采用内置USB固件与海量存储协议的主机芯片CH375,通过USB-Host主机接口将A/D转换器TLC2543采集得到的数据存入U盘.利用红外遥控键盘,配合中文液晶显示模块OC-MJ4X8C,构建系统友好的人机交互接口.整个系统具有简单、快速、使用方便等特点.

The whole system is based on the microprocessor ATmega32, using the host chip CH375 with a built-in USB firmware for mass storage protocol, and the data collected by .AiD converter TLC2543 is deposited into U-disk through the USB host. By using the infrared remote control keyboard and the Chinese LCD Module OCMJ4XSC, the friendly man-machine interacti-ve interface is built. The system is simple, fast and easy to use and so on.
