  • Page 7: Introduction

    User input on the GLK12232A-25-SM is available through a five by five matrix style keypad or a resistive touch overlay on the GLT12232A-SM. In addition, two general purpose outputs provide simple switchable five volt sources on each model, while a small piezo speaker offers audio feedback for a completely interactive experience.

    Distributed by www.texim‐europe.com 2.2 Standard Module The standard version of the GLK12232A-25-SM/GLT12232A-SM allows for user configuration of two common serial levels. The unit can communicate using serial protocol at either RS323 or TTL voltage levels. Connections for each serial protocol can be accessed through the six pin Communication/Power Header as outlined in the Serial Connections section below.

    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.

  • Page 11: Usb Connections

    The USB connection is the quickest, easiest solution for PC development. After driver installation, the GLK12232A-25-SM-USB/GLT12232A-SM-USB will be accessible through a virtual serial port, providing the same result as a serial setup without the cable hassle. To connect to your GLK12232A-25-SM- USB/GLT12232A-SM-USB please follow the steps below.

  • Page 12: Software

    3.1 MOGD# The Matrix Orbital Graphic Display interface, MOGD#, is offered as a free download from www.matrixorbital.ca/software/software_graphic. It provides a simple graphical interface that allows settings, fonts, and bitmaps to be easily customised for any application.

    Series. 3.3 Application Notes 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. 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.

    Figure 8: Extended Communication/Power Header The Extended Communication/Power Header provides a standard connector for interfacing to the GLK12232A-25-SM/GLT12232A-SM. Voltage is applied through pins one and four of the six pin Extended Communication/Power Header. Please ensure the correct voltage input for your display by referencing the Voltage Specifications before connecting power.

    NC/Vcc Figure 11: Alternate Power Connector The Alternate Power Connector provides the ability to power the GLK12232A-25-SM-USB/GLT12232A- SM-USB using a second cable. The Tyco 171825-4 style header is particularly useful for connecting to an unmodified floppy power cable, a 171822-4 for example, from a PC power supply for a simple bench power solution.

  • Page 16: Common Features

    Row 5 Gnd/Vcc* To facilitate user input, the GLK12232A-25-SM provides a Keypad Interface Connector which allows a matrix style keypad of up to twenty-five keys to be directly connected to the display module. Key presses are generated when a short is detected between a row and a column. When a key press is generated, a character specific to that key press is automatically sent on the Tx communication line.

  • Page 30: 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 31: Bitmaps

    Distributed by www.texim‐europe.com The character data is a binary graphical representation of each glyph in a font. Each character is drawn on a grid containing as many rows as the height specified in the header and as many columns as the width specified in the character table.

  • Page 32: 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 47: File Upload 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 48: Xmodem Upload Protocol

    XModem Upload Protocol In addition to its original simple upload format, Matrix Orbital has added an XModem based protocol. This facilitates much faster download speeds by increasing the packet size from 1 byte to 128 bytes and using only a two byte CRC for error checking, greatly increasing throughput.
  • Page 49 Distributed by www.texim‐europe.com The display then performs a CRC check on the data receive and ACKs if it matches that which was sent. Transfer continues with a block count and continues in this way until the end of file is reached. Files may be padded with 255 values to reach an even multiple of 128 bytes in size, but the download command will always report true size.
