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-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 better compatibility

控件注册问题 USBCLeaner自带控件与系统本身的控件版本不一致时会出现类似组件无法注册等提示,遇到这种情况,可以将prjXTab.ocx,COMCTL32.OCX复制到系统文件夹,XP一般是C:WindowsSystem32,NT一般是C:WiNNtSystem32下,然后 运行--Regsvr32 prjXTab.ocx Regsvr32 COMCTL32.OCX 一般就可以解决问题. -Control the registration of USBCLeaner own control and the control system itself will be different versions of similar components can not be registered, such as tips, encountered such a situation, can prjXTab.ocx, COMCTL32.OCX folder copied to the system, XP is usually C : Windows System32, NT is usually C: WiNNt System32 next, and then run- Regsvr32 prjXTab.ocx Regsvr32 COMCTL32.OCX general can solve the problem.
