Like uProject, MOGD# offers a scripting capability that provides the ability to stack, run, and save a
series of commands. The most basic function is the Send Numeric tool which is used to transmit a string
of values to the display to write text or execute a command.
Again, the clear screen command is sent to a connected display, this time using the MOGD# Send
Numeric function command style. Scripts can be run as a whole using the Play button from the toolbar
or as single commands by selecting Step; once executed it must be Reset. Before issuing commands, it is
a good idea to ensure communication with a display is successful using the autodetect button.
This program provides both a staging areas for your graphics display and a proving ground that will
prepare it for any application environment.
Beginning with revision 8.1, the firmware of the GLK240128-25/GLT240128 can be upgraded in the field.
Alternatively, the changes to the filesystem and subsequent commands can also be reverted by
downgrading the firmware to revision 8.0 using the same process.
All firmware revisions of the GLK240128-25/GLT240128 can be downloaded from

Full demonstration programs and code are available for Matrix Orbital displays in the C# language from
Simple C# AppNote Pack in the Application Note section at www.matrixorbital.ca/appnotes. Difficulty
increases from beginner, with the Hello World program, to advanced, with the Dallas One-Wire
temperature reading application.
Many additional applications are available in a number of different programming languages. These
programs are meant to showcase the capability of the display and are not intended to be integrated into
a final design. For additional information regarding code, please read the On Code document also found
on the support site.
