CHEAP serial 8x24 LCD!!!

edited 2003-05-20 13:29 in General Discussion
Electronics Goldmine sells a surplus LCD for $5 from an AT&T phone
terminal.

http://sales.goldmine-elec.com/prodinfo.asp?prodid=3438

With that and a programmed EEPROM from:

http://www.pjrc.com/store/39f512_jw002_plcc.html

It converts the display to a 8 line by 24 character serial terminal
at 19200,8,n,1. There is a command set for the display to change
fonts, scrolling, and more at:

http://www.pjrc.com/tech/mp3/lcd_protocol.html

So for about ~$25 (depending on shipping costs for the LCD and
EEPROM) you get a serial display that will work as long as you can
generate 19200 baud.

    this site will show you how to connect the display and use it on a serial
    port using a Max232.. http://www.btinternet.com/~e2one/lcd/lcd.htm

    Yes, but you still need the EEPROM from www.pjrc.com if you buy the
    display from Electronics Golddmine. Without the EEPROM is it just a
    door stop[noparse];)[/noparse]

    Hi Jason,
    have you tried this? it sounds too good to be true, $5 for the LCD? And its
    got a socket for the EEPROM! Just wondering, ;cause it doesn't mention PN
    JW-002 on the electronics goldmine site, but the hyundai part numbers do
    match up with the earth website. I'll buy one today, thanks for the tip!

    Jeff

    I got burned on a couple of off-brand / cheap serial converters with free
    LCD's. They eventually work if you cycle the power enough times, but not
    reliable enough for a real product. If you must do serial, go with the Scott
    Edwards stuff. Its pricey, but it works.

    Just out of curiousity...I've heard everyone mention
    the "Scott Edwards" stuff, which I myself have never
    tried, but I've never seen anyone mention the
    PIC-an-LCD by Dale Wheat (Which I HAVE tried, and it
    works nice) or the EDE702 (E-Lab, which I haven't
    tried, but have used their keypad decoder).

    I like the PIC-an-LCD solution, myself...And I find it
    quite easy to run with my BS2s with nothing more than
    the chip, crystal, a resistor and a capacitor, which
    isn't too bad when you can fit them in less space than
    the piggy-back boards.

    Anyone else?

    The ones I got were piggyback boards -- total Smile, and despite following
    their suggestions on power, etc... they fail to power up and initialize the
    LCD properly 9 out of 10 times.

    I guess that's the trouble you get going for cheap stuff.

    Another alternative is Matrix Orbital (www.matrixorbital.com). Not
    too pricey, but not cheap either.

    They make some fantasic serial LCDs. RS232, I2C, or USB
    based.

    They are easy to control too!!

    Examples on my web site: http://www.lennard.net.nz/ follow the
    links...


    Cheers,

    Ben,
