    Rayman,
    Very cool....
    Can you control the symbols at the top ?

    Does that byte of memory hold "A", 65, $41 or %01000001 ?
    Yes it does...

    Yep, each of the icons is individually controllable.· Four even have special commands devoted to them for some reason...

    What we really need now is a fast assembly driver to do 2 or 4 lines of·text·with graphics...

    Thinking about digging out some old Palm Pilot fonts...

    I'm interested in 1 of each (1 with prop, 1 without).

    Have we got final pricing? How would I pay (paypal?)

    There's no Prop on these breakout boards... It's made to plug into the Propeller Platform, but you can use it with Protoboard or pretty much any setup you want...

    I'm thinking $15 for the breakout board + display.

    Keep in mind though that there's no real driver yet, just some test code...

    Sounds fair. I'd still probably take 2. Postage would be to Australia, so don't forget to factor that into any calculation on $.

    Pacman, if you want someone to share postage with, I'll take 4.

    I'm leaning toward sending these to Gadget Ganster too, so we can leverage the Prop Platform with it...

    Just shipped the first 6 units to GadgetGangster.com to sell for me...
    Think we're looking at $15 each...

    Don't have a real driver yet, but Bean has volunteered to do it [noparse]:)[/noparse]

    But, I do have this demo code that is·a very basic driver...· It's shows the ROM Font on the screen.

    Rayman,
    I will probably use an 8x8 font to generate a 15x4 character display.
    Have the ability to plot points and draw lines.
    I'll have to see what is possible when I get the display.
    $15 for a 122x32 graphic LCD sounds like a great price to me. You shouldn't have any trouble selling them at that price.

    Bean.

    Rayman was kind enough to send me one of the modules and I have attach a propeller driver for it.

    For the text I used a 6x8 font to be able to get 20 characters across. It's a very readable font, even with it being so small.

    These are on sale at Gadget Gangster for only $9.99 right now http://www.gadgetgangster.com/find-a-project/56?projectnum=216
    That's a good price for a 120x32 graphic LCD with a backlight and alot of special icons too.

    Enjoy, and comments welcomed.

    Bean.

    That was fast!
    Just tried it on my Propeller Platform, but it didn't work [noparse]:([/noparse]
    I wonder if it's this issue with the data pins labelled backwards on the breakout board?

    When plugged into the Prop Platform, the real D7 is on pin 16 and the real D0 is on Pin 23...

    PS: Any chance I can talk you into putting an MIT license on this?

    Rayman,
    Oh, I didn't put ANY copyright on it. But I can put the MIT license on it if it makes life easier for ya.

    I used the Propeller Profesional development board, but it should work on other pins ???
    I just connected the pin in order starting at pin 0.
    Tell me what you have each pin connected to, and I'll try it.

    Bean.

    I just remembered that you can also plug it into the other side of the Prop Platform and their the data pins would be reversed:

    It works!

    Very nice!

    Here's the pins I'm using now and commented pins when on the other side:
    CON
      ' Change these pin numbers if you connect the LCD to different pins.
      PinRESn= 4'27  ' /Reset
      PinDC  = 5'26  ' Data /Command
      PinRW  = 6'25  ' Read /Write (can be just wired high, we never read back from the display)
      PinCSn = 7'24  ' Clock (data is read on falling edge) 
      PinD0  = 8'23  ' data byte bits are reversed to make wiring look better!
      PinD7  = 15'16 ' Note:  Breakout board has D0..7 labels backwards!
