<DS>
Download Screen
Pixel Graphics
Description
Download a full-screen 64 x 120 pixel graphic image to the screen.
Parameters
None
Modes
All Modes
The <WM
n
> Write Mode has no effect on this command
Notes
This command is really just a special case of the <DG> command, but because of the fixed size is
executed much faster.
This command ignores the current Write Mode setting, and draws the downloaded image to the
screen normally.
All other attributes are ignored, except those concerned with the ability to Flash the image.
The download mechanism is identical to the <DF
n
> Download Font and <DG> Download Graphic
commands. Detailed information is in the Graphics Transfer Section (Page 13).
The cursor position is unchanged by the command.
Uses
The <DS> command allows:
•
A full screen image to form a backdrop onto which standard text or data is then added
•
A customised logo to appear at power on when used with the <SL> Save Logo command
Example
<CS>
Clear Screen
<DS>
Tell the display to expect a 64 x 120 pixel graphics image that it
should display full screen.

Gotchas!
The logo is not stored in EEprom unless the <SL> Save Logo command is issued.
