Description: USB (Universal Serial Bus)是近年来发展起来的一种快速、灵活的总线接口。它最大的特点是易于使用，可热插拔，接口连接灵活，并且能够提供外设电源[4]，在嵌入式系统及智能仪表中获得广泛的应用。而51系列单片机以其优越的性能、成熟的技术、高性价比被广泛应用于测控仪器和自动化领域。因此用51系列单片机实现USB主机接口，进而实现对USB外设的控制，对提高整个系统的数据存储、数据传输、设备控制等性能都有很大的作用。

Description: 这个程序用180行C代码就能够读取FAT16文件系统U盘的根目录,可以看到根目录下的文件
名,并可显示
首文件内容,不过,该程序很不严谨,也没有任何错误处理,对U盘兼容性较差,只是用于简单试
验,作为参考.
这个程序可以支持WINDOWS按FAT16格式化的U盘,因为程序精简,所以只兼容超过50%以上的U
盘品牌,如果换
成CH375A芯片则兼容性可提高到85%,当然,如果使用WCH公司的子程序库或者正式版本的C源
程序兼容性更好。

未通过U盘:爱国者/智慧棒128M,清华普天/USB2.0-128M,当然,使用WCH的子程序库或CH375A
都可以测试通过
-this procedure with 180 OK C code can read FAT16 file system drives the root directory, we can see the root directory under the file name, would show the first document, but the very stringent procedures, and there is no error handling, the U-poor compatibility, but for the simple test a post-mortem as a reference. this procedure can be supported by Windows FAT16 formatted U disk, because the procedure is streamlined and therefore only compatible with more than 50% of the U-brand, if chips were replaced CH375A compatibility can be increased to 85%, if the company's use of WCH Subroutine Library or an official version of the C source code compatibility better.
