3.2Driver Files

The display driver and TV encoder DLLs must be included in the Windows CE image. To do this, make sure either Platform.bib or Project.bib includes statements for the display driver DLL and the TV encoder DLL. A Direct3D Mobile implementation module can be included optionally

For example, to configure the display driver and the Focus FS454 DLL:

#define INTELCEG_DRIVERS_DIR $(_WINCEROOT)\INTELCEG\drivers

 

 

ddi_iceg.dll

$(INTELCEG_DRIVERS_DIR)\display\i854\ddi_iceg.dll

NK

SH

fs454.dll

$(INTELCEG_DRIVERS_DIR)\display\i854\fs454.dll

NK

SH

To configure the Direct 3D module add:

 

 

 

 

 

 

gdld3dm.dll

$(INTELCEG_DRIVERS_DIR)\display\i854\gdld3dm.dll

NK

SH

3.3Registry Options

The MSI installs a configuration file that contains registry options. If you wish to keep this file separated, please make sure this file is included in either Platform.reg or Project.reg. For example:

#define INTELCEG_DRIVERS_DIR $(_WINCEROOT)\INTELCEG\drivers #include "$(INTELCEG_DRIVERS_DIR)\Display\I854\video.reg"

It is also possible to copy the contents of this fileinto the end of Platform.reg or Project.reg.

The registry settings in video.reg must be modified to configure the display driver and TV Encoder DLL to use on the target platform.
