Per Port Platform Customization

Intel^® EMGD provides what is considered the most useful tools to the embedded market — per port platform customizations. This includes the following:

• Defining custom DTD panel timings

: PixelClock, HorzActive, HorzSync etc...

• Customized GPIO pin selection for I²C and DDC communication with sDVO encoders and panels.

:I2cPin, I2cDab, I2cSpeed etc...

• Flat Panel width and height limitations and power and/or backlight control mechanisms

:BkltMethod, BkltT1, BkltT2, GpioPinVdd etc...

• Port driver specific attribute settings for initialization at boot time.

: Brightness, Contrast, H-Position etc...

All of the above can be set for each individual port depending on the maximum number of ports the chipset supports. Also, you can have multiple instances of these configurations to allow different settings per configuration.

The usage model for this per-config, per-port platform customizations follows after the same options available in the INF registry settings for the Intel Embedded Graphics Drivers for Microsoft Windows* XP. Please see Sample emgd.reg File or to the provided registry sample file in the Intel^® EMGD Windows * Embedded Compact 7 driver package for examples. The following sections provide information on these configurations:

• Per Port Customization — General Port Configuration

• Per Port Customization — Custom DTD Timings

• Per Port Customization — Custom Flat Panel Controls

• Per Port Customization — Attribute Initialization
