This option should be disabled unless the image is required for debugging.
This option enables special BLT debugging messages on the debugging serial port. This
option, when enabled, will drastically impact display driver performance, and should only
be used to track down failures in the BLT operations.
This option should be disabled unless doing BLT debugging.
This option enables special debugging code that will fill (blank) off-screen rectangular
surfaces when they are destructed. This option is only useful if EnablePreferVmem is also
enabled. When enabled, off-screen surfaces are filled with a solid color when they are
deleted. If any code then attempts to reuse the deleted off screen surface, the results should
show up as errors on the primary display.
This option should be disabled unless doing debugging.
The MODE tables (contained in files MODE0.H, MODE1.H, MODE2.H . . .) contain
register information to control the desired display mode. The MODE tables must be
generated by the configuration program 13506CFG.EXE. The display driver comes with
example MODE tables.
By default, only MODE0.H is used by the display driver. New mode tables can be created
using the 13506CFG program. Edit the #include section of MODE.H to add the new mode
table.
If you only support a single display mode, you do not need to add any information to the
WinCE registry. If, however, you support more that one display mode, you should create
registry values (see below) that will establish the initial display mode. If your display driver
contains multiple mode tables, and if you do not add any registry values, the display driver
will default to the first mode table in your list.
To select which display mode the display driver should use upon boot, add the following
lines to your PLATFORM.REG file:
[HKEY_LOCAL_MACHINE\Drivers\Display\S1D13506]
"Width"=dword:280
"Height"=dword:1E0
"Bpp"=dword:8
"Rotation"=dword:0
"RefreshRate"=dword:3C
"Flags"=dword:2
