| 摘 要： | 介绍一款单片机存储设备转储器,以C8051F040为核心控制模块,通过外接两个CH375 U盘模块、液晶显示模块及键盘模块等实现两个U盘之间数据的相互转储,很好地解决了U盘内容转储离不开电脑而带来的不便以及容易感染病毒等弊端。C8051F040通过CH375按照相应的USB协议与USB设备通讯,通过调用CH375提供的子程序库来直接读取U盘中的数据,实现了普通单片机与U盘的通讯,支持常用的12 Mb/s全速USB设备和1.5 Mb/s低速设备。该设计方案具有低成本、低功耗、操作简单等特点,将会有广阔的应用前景。

| Abstract: | A file dump storage device based on MCU was introduced.As the control core of system,the C8051F040 MCU connected two CH375 U-disk modules,one LCD screen and the keyboard module to realize communicating between two U-disks directly and independent of PC,which made the U-disks not susceptible to viruses.The C8051F040 MCU realized the communication by USB protocol and USB equipment,which supports top speed(12Mb/s) equipment and low speed(1.5Mb/s).The operator can use the program given by the CH375 to read the data from the flash disk and realize the communication between MCU and the flash disk.The device has merits of low lost,low power loss,simple to operation etc,it has widely application prospect. |
