A quick question on LCDs

I have a BS2sx and was wondering if I could use any type of serial
LCD with it or do I have to use the ones made for stamps such as the
Scott Edwards LCDs?

Thanks in advance!

    You can use any. Again, they are serial. I use the EDE702? chip from
    www.elabinc.com

    Any serial LCD should work fine with the stamp. I've used several
    different serial LCDs, all with good results.

    FWIW, you might want to check out the Matrix Orbital
    (www.matrix-orbital.com) units. They also have an I2C interface, if you
    ever plan to use a BS2p, the I2C interface is very nice for savings
    pins.

    They should all work, most some are inferior -- either learn to use a
    parallel LCD of go with the Scott Edwards unit.

    Hit google and search for "bs2 lcd" there are tons of examples of how to
    hook up parallel lcds. The serial ones are harder to get and cost a fair bit
    more.

    If you search for PCF8574 LCD BS2 you'll find some examples of how to hook
    up a parallel LCD with only a few pins (74HC595 versions abound too).

    I use the HD44780 LCDs I find 2 line and 4 line LCD's at our monthly
    get togethers... I usually pay from 2 to 10 dollars each depending
    on how many I am getting. I can usually spare 6 pins on a project to
    run the display. I have a very easy to use LCD program I will be
    uploading soon.

    Allan,

    You can basically use just about any LCD of your choice. It really
    depends on how much work you're willing to do on your end. I'm using
    a 1/4 vga graphics display with my BS2. The best part is that I don't
    have to use any of the I/O pins in order to interface to the LCD. I
    simply use the Stamp's serial lines to communicate to the LCD.
