求助WINCE6固定i/o地址数据读取驱动 [复制链接]

 

DWORD aaa_Read(DWORD hOpenContext, LPVOID pBuffer, DWORD Count)
{                                                           
 Paaa_PUBLIC_CONTEXT paaaPublic = (Paaa_PUBLIC_CONTEXT)hOpenContext;
    WORD read[1];
    read[0] = *ADD;
 RETAILMSG(1,(TEXT("GIO_Read: Read Success!\r\n"),read[0]));
 memcpy(pBuffer,read,sizeof(read));
 return TRUE;
}

运行时当点击button时开发板界面弹出错误信息：“an invalid argument was encountered”
驱动调试窗口信息为：
GIO_Read: Read Success!
Exception 'Raised Exception' (-1): Thread-Id=0693008e(pth=846b27e0), Proc-Id=066d0072(pprc=846b26c0) 'gpio.exe', VM-active=066d0072(pprc=846b26c0) 'gpio.exe'

小弟实在不懂哪里出了问题，恳求各位大侠相助，先谢谢了！！！
