谁能发一份基于CH375主机模式的c源代码给我吗？我急用，需要底层的库文件，沁恒只给出了简单的文件级系统，没有给出USB底层读写源程序

主要是下列程序的源代码： extern UINT8 CH375GetVer( void ); /* 获取当前子程序库的版本号 */ extern void CH375Reset( void ); /* 复位CH375 */ extern UINT8 CH375Init( void ); /* 初始化CH375 */ extern UINT8 CH375DiskConnect( void ); /* 检查磁盘是否连接 */ extern UINT8 CH375DiskReady( void ); /* 查询磁盘是否准备好 */ extern void CH375DirtyBuffer( void ); /* 清除磁盘缓冲区 */ extern UINT8 CH375FileOpen( void ); /* 打开文件或者枚举文件 */ extern UINT8 CH375FileClose( void ); /* 关闭当前文件 */ #ifdef EN_DISK_WRITE extern UINT8 CH375FileErase( void ); /* 删除文件并关闭 */ extern UINT8 CH375FileCreate( void ); /* 新建文件并打开,如果文件已经存在则先删除后再新建 */ #endif extern UINT8 CH375FileModify( void ); /* 查询或者修改当前文件的信息 */ extern UINT8 CH375FileLocate( void ); /* 移动当前文件指针 */ extern UINT8 CH375FileReadX( void ); /* 从当前文件读取数据到指定缓冲区 */ #ifdef EN_DISK_WRITE extern UINT8 CH375FileWriteX( void ); /* 向当前文件写入指定缓冲区的数据 */ #endif #ifdef EN_BYTE_ACCESS extern UINT8 CH375ByteLocate( void ); /* 以字节为单位移动当前文件指针 */ extern UINT8 CH375ByteRead( void ); /* 以字节为单位从当前位置读取数据块 */ #ifdef EN_DISK_WRITE extern UINT8 CH375ByteWrite( void ); /* 以字节为单位向当前位置写入数据块 */ #endif #endif extern UINT8 CH375DiskSize( void ); /* 查询磁盘容量 */ extern UINT8 CH375DiskQuery( void ); /* 查询磁盘信息 */ #ifdef EN_SAVE_VARIABLE extern void CH375SaveVariable( void ); /* 备份/保存/恢复子程序库的变量,用于子程序库在多个CH375芯片之间进行切换 */ #endif extern UINT8 CH375BulkOnlyCmd( void ); /* 执行基于BulkOnly协议的命令 */ extern UINT8 CH375sDiskReady( void ); /* 查询磁盘是否准备好,支持CH375S */ 希望有的支持一下

底层的读写程序，也就是扇区读写。 下载CH375EVT.ZIP，参考CH375EVT\PUB\MCS51C\MISCELL下的示例，可免费提供的，也就这么多。 另，我司有另外一份CH375文件系统源码CH375SR2（与公版的库源码不同），如有需要请致电销售：025-52638355/77/88/99

需要最关键的两个函数： extern UINT8 CH375FileReadX( void ); extern UINT8 CH375FileClose( void );

这两个函数的源码是不会提供的 （1）CH375FileReadX也就是调用底层的读扇区，示例中也有读扇区的过程 （2）CH375FileClose主要是更新了文件长度，即把文件长度写入目录项

我买了两片CH375的芯片，是沁恒公司的，但是沁恒没有给出底层代码，让我的工作做起来很难，不知道你是那个公司的，如果不行，我只好自己做底层了

用下载的代码写出的文件级程序运行不了，能不能提示一下，怎么做才能让CH375读写U盘？

我是指如果下载的程序可以完成读写的话，希望你能指点一下，如果下载的程序就是个框架，那在不批量购买CH375的时候，底层是不是只能购买？

用我们的子程序库就可以了,应该能满足您的要求.不知道您用的MCU是什么型号的?低层的程序我们封装起来了,您看不到代码.

用的是宏晶的89C52RC，程序编译后大体上有如下的警告，不知道是为什么？请指点一下 Build target 'Target 1' compiling test5.c...

52单片机的资源不够. 出现上述错误和警告,可能是库连接不正确,请参考: /bbs/View.asp?S=101&I=1511

出一下警告是为什么？我连接的没什么错误啊。资料n 多，看的我眼花缭乱

不能发图片，如果你们能看到图片也许更能明白问题在那

这些么有写程序

做了个例子请参考:UploadImages/200810201515456.rar

非常感谢版主的帮助，我们准备把CH375用在油田钻井测量设备的数据采集上，U盘做好就一切OK了
