    DOS output to Matrix-Orbital display?

    Has anyone heard-of or written a plugin for a dos MP3 player that will output to a Matrix-Orbital LCD display? If not, I'll just run linux, but Dos is easier to set up and there are no shutdown problems. I already have the display, so don't bother suggesting a different one.

    A plugin called MPXF for MPXPlay seems to do this.. follow <a href="http://www.mp3car.com/ubb/Forum3/HTML/000020.html">this</a> thread..

    I don't think that that Matrix-Orbital displays are "Hitachi HD44780 interfaced" which MPXF claims to support. Thanks for the info though.

    I should be able to add support for the Matrix-Orbital display. It looks like it uses the serial port instead of the parallel port to interface the LCD. The commands are a little different as well. Of course, its hard to program something for hardware you don't have. :-)

    I could send you a copy of the documentation. It comes with a booklet that has all of the command set and what you need to interface with it. I would do it but I'm not much of a programmer. If you mail me at meatballman@bigfoot.com I will scan in the booklet and email it to you. I may even OCR it...

    This is primarily for Coldblood

    If you can make MPXF compatible with Matrix-Orbital display, is it possible that you make support for some kind of universal serial interface. I mean that there could be an .ini file that descibes what command are send to the display and how plugin reacts to characters that are received from keypad ( if there is a keypad connected to display).

    Example of .ini:

    [SerialPort] = com1
    [Baudrate] = 9600
    [Databits] = 8
    [Stopbits] = 1
    [Parity] = no
    ;Output commands:
    [GoLine1] = 0x13
    [GoLine2] = 0x14
    [BacklightOn] = 0xE0
    ;Input commands
    [Play] = 0x01
    [Stop] = 0x02
    [ShutDown] = 0x05,0x06

    By modifying the .ini the MPXF would be compatible with all serial LCD/Keypad interfaces like Matrix-Orbital, Scott Edwards Electronics and my <a

    Thanks for the info Martzis. I'll get started on a serial LCD interface for it MPXF soon.
