I am new in this field and i desperately need some guidance from u all.
I have to support yuv444 to rgb 888 in display driver module.
There is one test which i have done for yv12 → rgb565 in wince 6.0 r3 which is mentioned below.
//------------------------------------------------------------------------------
//
// Function: PP_CSC_YV12_RGB565Test
//
// This function tests the Post-processor
//
//
//
// Parameters:
// uiMsg
// [in] Ignored.
//
// tpParam
// [in] Ignored.
//
// lpFTE
// [in] Ignored.
//
// Returns:
// Specifies if the test passed (TPR_PASS), failed (TPR_FAIL), or was
// skipped (TPR_SKIP).
