3.1.12.1 Write Parameters

Table 3-21 describes the write parameters.

Table 3-21 Write Parameters
Parameter BytesDescription
Byte 1Pixels per line (LSByte)
Byte 2Pixels per line (MSByte)
Byte 3Lines per frame (LSByte)
Byte 4Lines per frame (MSByte)

Default: DMD resolution.

  1. This command specifies the size of the non-keystone corrected image to be output from the scaler function, which equals size of the active displayed image. Start pixel and Start line are default to 0.
  2. The parameter values are to be ‘1’ based. (that is, a value of 1280 pixels displays 1280 pixels per line).
  3. All sub-images (images smaller than the DMD display) can start on any active area of the DMD. There is no sub image rotation and keystone support. The subimage display range is

    Horizontal range: DMD width – Subimage Pixels per line

    Workable x coordinate is 0 to (DMD width – Subimage Pixels per line – 1)

    Vertical range: (DMD height – Subimage Lines per frame)

    Workable y coordinate is 0 to (DMD height – Subimage Lines per frame -1)

    Example: If the display subimage us 600x600 and DMD size is 1280 × 720.

    Horizontal range: 1280 – 600 = 680, the workable x coordinate is 0 to 679.

    Vertical range: 720-600 = 120, the workable y coordinate is 0 to 119.

  4. If the display size exceeds the resolution of the DMD, the controller issues an error (invalid command parameter value – communication status) and the command does not execute. Specifically, the controller compares the display size parameters to the DMD resolution in both rotation image orientations (non-rotated and rotated), and if the DMD resolution is exceeded in both of these orientations, the controller issues an error. Note that the system does not check for proper image orientation setup.

    DMD resolution = 854 × 480:

    • Example 1: Display size parameter = 480 × 854 (not an error)
    • Example 2: Display size parameter = 900 × 320 (error)
    • Example 3: Display size parameter = 500 × 600 (error)

  5. If the source and display parameter combinations exceed the capabilities of the scaler, the system tries to implement what is requested by the user, and a broken image may be displayed. The user must provide updated parameters to correct the image.
