通过SMDK210自带的DOC《SMDKV210_WinCE60_TVOUT_UserManual.pdf》了解到
其HDMI驱动通过应用程序DeviceIoControl调用
操作顺序是：
1.打开TV
2.打开图像层（GRP层）
3.打开视频层（Video层）
4.再配置HDMI相关

给了我很大启示，网上很多人是在研究直接把fb放到GRP层，可是这样不能全屏的问题
发现Video层可以轻易解决大小的问题，但是现在卡在Video层需要YUV格式
而fb读出来的是RGB格式
DOC中
// because video processor supports only YUV420 NV12 type, need 2 values about address
unsigned int uiTopYAddress; // Y data start address of source image
unsigned int uiTopCAddress; // C data start address of source image
所以，我在研究怎么解决这个格式转换问题，有大神说用VP——VIDEO PROCESSOR
不知道是什么东西，估计只能明天再话精力了解了。
今天code出来的：
DWORD dwBytes;
// Turn on TV
//1st Step: Driver Open
HANDLE hVideoDrv =INVALID_HANDLE_VALUE;
hVideoDrv = CreateFile( L"TVD0:", GENERIC_READ|GENERIC_WRITE, FILE_SHARE_READ|FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, 0);
if (hVideoDrv == INVALID_HANDLE_VALUE)
{
RETAILMSG(1,(L"[VDE:ERR] TVD0 Open Device Failed\n"));
return;
}
//Read HPD status
bool bHpdStatus;
DeviceIoControl(hVideoDrv, IOCTL_STDA_HDMI_GET_HPD_STATUS, NULL, 0, &bHpdStatus, sizeof(BOOL), &dwBytes, NULL);
if(bHpdStatus == FALSE)
{
RETAILMSG(1, (TEXT("bHpdStatus is false!\r\n")));
//exit(0);
}
//If HPD status is plugged, you should read HDMI available mode.
