(1) Won't work unless the driver already supports rotation. Apparently
yours doesn't.
(2) Looks like the driver doesn't support rotation. There's a little more
to getting it to work than just calling a couple APIs. It's actually not
that difficult, but you or whoever is writing the driver will have to do the
work to implement it.

Hi,
I am using WinCE4.2 core on an embedded arm board which is bought
online. I have tried 2 methods to rotate the screen:
1. Try writing eVC program with the code here:
DEVMODE DeviceMode;
memset(&DeviceMode, NULL, sizeof(DeviceMode));
DeviceMode.dmSize=sizeof(DeviceMode);
DeviceMode.dmFields = DM_DISPLAYORIENTATION;
DeviceMode.dmDisplayOrientation = DMDO_90;
However, the WinCE screen has not rotated.
2. Try change code in the BSP file
$(_WINCEROOT)\PLATFORM\smdk2440\drivers\display\S3C2440lcd
\s3c2440disp.cpp
Original code is
#ifdef ROTATE
m_iRotate = 0;
SetRotateParms();
#endif //ROTATE
changing to
//#define ROTATE
#ifdef ROTATE
m_iRotate = DMDO_90;
SetRotateParms();
#endif //ROTATE
But the compilation generates many errors.
Could anyone help me to explain why this happens or how can I do the
rotation?
Thanks!
.
