关于动态加载中断流驱动
1:如果加载驱动不成功 首先注意你的XXX_Open() 那3个XXX是否大写
2:对于WINCE4.2以上的版本,动态加载中断流是不成功的啊
但是我的版本是WINCE5.0,而且我大小写都注意了,我就是用CE驱动调试助手激活我的中断驱动就是不成功啊
希望大侠们指点
放出我的程序

[解决办法]
加载到哪一步不成功，请看打印信息，你打包这个驱动能用吗？
注意在XXX_DeInit函数必须把系统中断释放，否则卸载驱动再次加载会造成一个物理中断对应多个系统中断，这样是不会响应中断的。
[解决办法]
怎么个不成功法？
基本上，只要注册表没错，加载应该是没问题的。
[解决办法]
驱动加载不成功和你的KEY_init函数有很大关系。
如果跟不了代码，建议在KEY_init()中插入日志打印语句，看到底是哪步有问题，定位了这个再说。
例如：
DWORD KEY_Init(DWORD dwContext)
{
RETAILMSG(1,(TEXT("KEY_Init----\r\n")));
// 1. Virtual Alloc
EINT_InitAddress();
RETAILMSG(1,(TEXT("EINT_InitAddress done...\r\n")));
KeyGpioInit();
RETAILMSG(1,(TEXT("KeyGpioInit done...\r\n")));
for(int i=0; i <4; i++)
{
g_ahKeyEvent[i]=CreateEvent(NULL,FALSE,FALSE,NULL);
}
RETAILMSG(1,(TEXT("Create 4 Events done...\r\n")));
if (!InitInterruptThread())
{
RETAILMSG(1,(TEXT("Fail to initialize userkey interrupt event\r\n")));
return FALSE;
}
//mInitialized = TRUE;
return TRUE;
}
