在PB中实现wince流式接口驱动【转】

转自：http://blog.21ic.com/user1/1015/archives/2008/50616.html

1.在PB中建立一个平台,自己使用的是X86仿真环境裁减的一个系统.

2.在PROJECT中新建一个WIN32 DLL项目.

3.在C/C++原文件中增加函数.

4.编写DLL的导出函数定义文件.DEF

5.选择编译.到了此处,我才发现我建的这个DLL项目有问题,一直说缺少ceddk.h这个头文件.最后的解决方

法是我把自己裁减的这个系统目录下面的WINCE500目录下的有关的头文件都考到DLL项目的目录下面

了.另外,还需要设置DLL项目的属性.右键点击DLL项目,选择SETTING,然后在这几个选项中进行目录设

置.

6.编译结束,OK之后,查看DLL是否正确的导出了这些函数.在PB 中选择Build菜单中的Open Build

Release Directory打开命令提示符,输入   dumpbin/exports Motor.dll

看到.DEF文件中的函数了,就证明是已经正确导出了.

7.为驱动程序配置注册表.下载BUILTIN下.

8.写程序,进行验证.

9.查看运行状况.当wince系统启动完毕之后,在PB的tool菜单下,选择Remote Process Viewer,定位到

Device.exe,可以看到Motor.Dll已经被系统加载了.

以下是一些代码,供自己留个纪念.
