S5PV210 WINCE HDMI全屏显示的问题
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：
