3. Create. This time you're on your own. While there are many examples within the Matrix Orbital AppNote section, www.matrixorbital.ca/appnotes, too many controllers and languages exist to cover them all. If you get stuck in development, it is possible to switch over to another protocol on the standard board, and fellow developers are always on our forums for additional support. -

See the Manual Override section to reset to default. • Make sure that the start screen is not blank. It is possible to overwrite the Matrix Orbital logo start screen, if this happens the screen may be blank. Try writing to the display to ensure it is functional, after checking the contrast above. -
Page 16: Manual Override
• In I C mode, connect Rx to the clock line of your controller and Tx to the data output. • Unlock the display. See the Set and Save Data Lock command for more info. • Finally, you may reset the display to its default settings using the Manual Override procedure outlined below. -

Page 22: Font File Creation
Front files alter the style of text and appearance of the display. By default, a Matrix Orbital graphic display is loaded with a small filled font in slot one and a future bk bt 16 style in slot two. Both are available at www.matrixorbital.ca/software/graphic_fonts. -
Page 23: Bitmaps
The character table contains information that allows the display to locate each individual character in a mass of character data. Each character has three bytes; two indicating it’s offset in the character data and one indicating its width. The offset takes into account the header and table bytes to point to the first byte of the character data it references. -
Page 24: Bitmap File Creation
Bitmap file data, see the Bitmap File Creation example. Bitmap File Creation In addition to fonts, Matrix Orbital graphic displays can also hold a number of customizable bitmaps to provide further stylistic product integration. Like font files, bitmaps files are most easily uploaded to a display using MOGD#. -

Page 29: File Transfer Protocol
Once a bitmap or font file has been created and paired to its command it must be sent using a file protocol developed specifically for Matrix Orbital displays. Once a file upload command has been sent requesting a unique reference number and specifying the file size required, the display will respond indicating whether it has enough room to save the file or not. -
Page 30: Data Security
Once a file is confirmed to fit within the display, the upload will begin. A protocol is used here to ensure each byte is uploaded successfully. After each byte is sent, the module will echo it back to the host. It should then be checked against the value originally sent before a confirmation byte of 1 is returned. -
