3.1.1.1 Write Parameters

Table 3-2 describes the write parameters.

Table 3-2 Write Parameters
MSBByte 1LSB

BitTypeDescription

2-0W

Input Source

0h = Test Pattern Generator from XPR FPGA

1h = External Parallel Video from XPR FPGA

2h = FPD-Link or LVDS Source from XPR FPGA

3h = Internal Controller Splash Screen

4h = Internal Controller Test Pattern

5h - 7h = Reserved

MSBByte 2LSB

BitTypeDescription

0W

External Calibration Setting

0h = External Calibration Disabled

1h = External Calibration Enabled

Note:

When selecting the Test Pattern Generator from FPGA, there is one associated command that is only applicable to this source selection. This associated command is the Write XPR FPGA Test Pattern Select (67h) command.

When selecting the Splash Screen, there is one associated command that is only applicable to this source selection. This associated command is the Write Splash Screen Select (0Dh) command.

When "External Calibration" is enabled, the system is reconfigured to disable all FPGA image processing. This allows the user to inject their own test patterns for calibration purposes.

The following commands are shared among "External Video Port", "Test Pattern Generator" and "Splash Screen" input select options:

  • Write Display Image Orientation
  • Write Display Image Curtain
  • Write Look Select
  • Write Local Area Brightness Boost Control
  • Write CAIC Image Processing Control

While the values for these commands may be the same across the different input source types, the hardware settings may change. For example, if the user changes to a "Test Pattern Generator" Input Source, the size of the test pattern must match the size of the DMD. Therefore, the display scaler settings may need to be changed.

Note:

The user is required to specify the active data size for all external input sources using the Write Input Image Size command. In addition, for input image data on the Parallel bus that doesn’t provide data framing information, the user is required to provide manual framing data using the Parallel I/F Manual Image Framing command.

Note:

When a test pattern is selected, it will be generated at the resolution of the DMD.

Note:

The user should see the Write Image Freeze (1Ah) command for information on hiding on-screen artifacts when selecting an input source.
