谢谢_study_ { M }，问题解决

谢谢，现在终于调通了。我把你们\CH375EVT\PUB\MCS51C\FILELIB4\EXAM1 中的hex文件下载进去，运行正常，如下： Start Wait Udisk Ready ? Open List file \* match file 000#: \USB-HO~1.PDF match file 001#: \USB-HO~2.PDF match file 002#: \电路图~1.PDF match file 003#: \USB芯~1.PDF match file 004#: \CH375~1.PDF match file 005#: \USB总~1.PDF match file 006#: \CH372DS1.PDF match file 007#: \USB_总~1.PDF match file 008#: \GSM参~1.DOC match file 009#: \其中检~1.DOC match file 010#: \XT5-82~1.PDF match file 011#: \NEWFILE.TXT Create Write Modify Close 但是我把CH375HFT.C文件复制到自己新建的工程中（用的keil）中，未做任何修改，把生成的hex文件下载进单片机，却得不到如上的结果，而是一直输出start，为什么？程序会一直输出start，我需要做什么修改？

程序编译链接有没有提示什么警告错误呢？

有85个警告啊，但是不知道具体什么意思？！如下：（有些长，见谅下哈） Build target 'Target 1' assembling STARTUP.A51... compiling cs.c... linking... *** WARNING L16: UNCALLED SEGMENT, IGNORED FOR OVERLAY PROCESS SEGMENT:

这表示库没有链接进去，把库当成一个C文件添加到工程中

哪一个库啊？能提供各名字吗？我没找到啊？！谢谢了……

是CH375HF4.LIB吧？！

谢谢你，SCM { M }的耐心指导。现在包含进来了，还有一个警告，如下 Build target 'Target 1' assembling STARTUP.A51... compiling cs.c... linking... *** WARNING L16: UNCALLED SEGMENT, IGNORED FOR OVERLAY PROCESS SEGMENT: ?PR?CH375FILELOCATE?CH375SEC Program Size: data=113.5 xdata=30749 code=10671 "cs" - 0 Error(s), 1 Warning(s).是什么意思啊？！

不好意思，网络不好，回复重复了！见谅！

未调用的段，这个没关系，不用关心，只是有个函数没调用

嗯，谢谢哈！现在程序调试通了……

请问版主，我把配套的示例程序（个人没有修改过）下载到STC90C50AD中，串口提示为 Start&nbsp375&nbspdemo&nbsp..n Set&nbspUSB &nbspmode

Error:&nbsp81

请问这是初始化时的错误吗？是不是硬件上的错误？我用的程序没有针对我的芯片进行修改，是不是就是出错的原因？我应该对程序进行那些修改呢？硬件I/O接口子程序又是应该怎样修改，放到什么位置呢？请指教，谢谢！

81应该是CH375硬件错误,你在设置模式之前加个复位CH375的命令试试（我非公司人员，不专业，见谅）
