（1）可以实现 （2）文件格式是由用户自己去实现，库只负责把数据写入U盘，不对文件格式作任何处理。如：123.DOC，那么需要你把数据封装成DOC格式再写入U盘，在PC上用Word打开即可

谢谢了，好的再请教时只在一个版面回复！

有谁用过Silion Laboratories IDE的吗？我把LIB文件加到Project中，然后打开它里面什么也没有。编译还是错的。谁来救救我啊！

已经给你发了参考程序.请到你发贴地方下载.

我用的是ICC7.14C，是怎么回事呀

这是6.31版本下的例程：UploadImages/20092171110731.rar

直接拿UploadImages/20092171110731.rar这个例程， 在ICC6.31A内，芯片选择Atmega128; Attitional lib.填入CH375HFB; 库文件复制到\ICC\include,头文件复制到\ICC\lib并更名为libCH375HFB.a; 编译运行，出现同样的错误

（1）在ICC6.31A下，例程不需要做任何修改，直接编译就行了 （2）库的名称也不需要修改，你修改的是WINAVR GCC下库的命名方式 （3）库的添加方式也不对，与添加C文件的方法一样，参考该主题的首贴

还是不对，依照您所说的，直接编译（但是有修改了下安装目录，我的安装目录不是在D:\Program Files\ICC），结果还是一样

请问： 用codewarrior 怎么添加库文件啊？ 谢谢啦！！

是ARM的编译器么？若是，该主题首帖上有啊

不是arm，用codewarrior 3.1 ，单片机是freescale的s12s系列的

采用哪款芯片，CH374/CH375？下载CH374LIB.ZIP/CH375LIB.ZIP，..\MC9S12下的库 添加的方法应该和ARM的一样，可以先试试

我们现在只有支持这个的库: MC9S12: Motorola/Freescale MC9S12系列单片机 | | |-- FILELIBQ: 增强版U盘文件级子程序库, Banked Memory Model | | |-- FILELIBQ_SM: 增强版U盘文件级子程序库, Small Memory Model

CH375文件系统库-CH375HFx.LIB，这个库文件在哪边啊？怎么在KEIL里找不到啊？
