    Hi there,
    I'm searching a I2C or SPI LCD. Could you help me where I find
    documents about I2C or SPI LCD? Which companies produce these? Do you
    tell me web address about these?
    thanks...

    take any HD44780-compatible LCD, add a PCF8574A (I2C) or 74HC595 (SPI)
    and you are done. NB I sell all three.

    Good idea! But I want a device which both I2C(or SPI) and LCD are
    together. If I don't find I2C or SPI LCD, I'll try other ways.
    Thank you very much for your suggestion.

    and LCD + one chip....

    I've used their parallel LCDs for a couple of years now.

    I use the Noritake Itron VFD Displays in all three of their operting
    modes, that are serial, I2C and SPI. I did a lot with those LCD (
    grafical and text only ones) but I wasn't proud of their bad viewing
    angles and temperature sensitivity. And they all needed to much port pins.

    As those VFDs have a 4x4 keyboard matrix controller implemented they
    save additional port an memory if used with small controllers. Thats
    worth the price.

    Have a look at http://www.noritake-itron.com/
    In germany the GU180x32D-K610A2 costs about 80 EUR which not much
    compared with an adequate fully graphical LCD which needs additional
    backlight, backlight inverter and negative supply for contrast, extra
    keyboard controller and I2C or SPI converter.

    Regards

    Ulrich
