Embedded controller board w/800x600 color LCD controller ?

Discussion in 'Embedded' started by Robert Lacoste, Sep 15, 2003.

  1. Hi,

    I'm looking for an embedded processor board or module with an on-board LCD
    controller chip able to drive a 800x600 color touchscreen LCD. I have in
    mind a PC compatible solution (PC104 or similar), but would like to know
    which other solutions are available on the market (coldfire ? others ?).
    Should support Linux or a real-time Linux version, should have support for
    flash memory (256Mb or more).

    Thanks !

  2. I'm looking for an embedded processor board or module with an on-board LCD
    www.revely.com RMS101 - the LH79520 can handle 800x600 color LCDs.
    Not *explicitly* ported to the RMS101, but the '520 can of course run
    ARM-Linux. The board has a little on-board NOR flash (bootable) and an
    MMC slot for storage.

  3. Thanks Lewin, but this one doesn't seems to support direct connection to LCD
    panels (I mean without VGA to LCD circuitry in the LCD...). What I need is
    ideally a chipset driving directly a dumb LCD panel. Anyway I will
    investigate a little more...

  4. Thanks Lewin, but this one doesn't seems to support direct connection to LCD
    For people reading the NG - this discussion was continued in email.
    The RMS101's processor (LH79520) has direct drive for parallel
    TFT-LCDs built in. The designer of this particular board has put a DAC
    on them, but you could just as easily put an LVDS transmitter on them
    for modern LVDS LCD panels.

    Another good candidate (especially now the OP tells me it's for
    largish production) is the Compulab (Israel) ARMcore,

  5. How about a half-creditcard sized TQM823L PowerPC module? Power
    consumption is less thn 2 Watts worst case. Comes with U-Boot and
    Linux. RTAI supported. Microwindows running out of the box.

    See http://www.denx.de/re/TQM8xxL.html for some images

    It's a nice product, I would love to play with them. But I WISH YOU
    WOULD PUT SOME APPROXIMATE PRICING on your site! Even just the two
    extremes; "sample pricing $XXX, down to as low as $YYY in large
    volumes" would be a fantastic help.

    Both these boards can directly drive a 800x600 flat panel (digitally)
    and have the option of a touch-screen interface.

  8. You can also check out http://www.zendex.com they have a PC/104 board,
    which has a Linux version resident and bootable from flash. The LCD
    and backlight can be powered from the board.

    Good luck,

    As Lewin alluded to, the LH79520 can drive 800 x 600 TFT panels. The
    interface to these is direct. I know...I've tried it.

    Another SBC option is a Logic card engine that has Linux ported to it
    already. You can read more about these at:

    You can buy the Zoom Starter Kits for $299 from distributors such as Future
    & Avnet. The Linux BSP is a free download you can get once you register
    which has alot of the Zaurus Apps (QT/Embedded, Konqueruer Browser) included
    in it. In addition, to make things easy, Logic has a 12.1" SVGA (800 x 600)
    display kit that will plug right into the Zoom Starter Kits. Read more on
    these at: http://www.logicpd.com/eps/peripherals.php

    Not quite sure how the LH79520 will perform with Linux & a SVGA display, but
    if it runs too slow, you can bump up to the LH7A400 (ARM9) Zoom Starter kit
    for $349. Not a bad deal!
