uProject
The Matrix Orbital alphanumeric display tuner, or uProject, is offered as a free download from the
www.matrixorbital.ca support site. It allows the basic functionality of any display*
to be tested using a
simple graphical user interface system.
While basic functionality can be tested using the GUI portion of the program, more advanced users will
enjoy the scripting capability found in the uploader tab. Here commands can be stacked, run, and saved
for later use. Although many commands are available to be dragged into the script dialog, perhaps the
most powerful is the raw data command found in the other branch.
This command allows raw bytes to
be sent to the display, permitting many different formats for entry
and displaying in decimal notation. Any command from this manual may be entered in decimal notation
separated by slashes.

Figure 10: uProject Command
Again, the clear screen command is sent to a connected display, this time using uProject raw data
command style. Scripts can be run as a whole using the execute command from the script menu, or as
single commands by selecting execute once. Before issuing commands, it is a good idea to ensure
communication with a display is successful using some of the more basic GUI functions in the main
window.
This program provides scratch pad upon which a tome of display projects and ideas can be assembled.
*Note:
The uProject AutoDetect function will not perform correctly when a USB display is connected. Please
manually configure any USB display.
Application Notes
Full demonstration programs and code are available for Matrix Orbital displays in the C# language from
Simple C# AppNote Pack in the Matrix Orbital 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.
