LCD Question

Hi all,
I have a Scott Edward 2x16 Serial LCD and I want to know how to do custom
characters using my BS2 (please no code for a BS1, I only have BS2's). I
read the LCD's instructions but I am still a bit unsure on how to make a
custom characters. Any help would be great, code with notes on how to edit
it to meet my need would be great! Thanks in advance!

    There are several program examples for special characters on the
    seetron.com web site. Download the file www.seetron.com/bpk_ex1.zip
    and look at the program spechar.bs2 for the simplest example.

    Also see www.seetron.com/an_cc1.htm for an online bitmap calculator
    (draw the symbol on screen, then copy the bitmap data into your
    program.

    More? OK, www.seetron.com/an_bar1.htm shows a simple way to use the
    custom-character capability to draw bar graphs. And
    www.seetron.com/an_odo1.htm presents a program that creates a
    vertically scrolling odometer-effect (an animation on the page shows
    how it looks--hard to describe).

    Look around the app-note index at www.seetron.com/lcd_andex.htm for
    more example programs and background information.

    Quick commercial note: BPI-216N is on sale for almost 20% off at the
    Seetron online store--see www.seetron.com for details.

    anyone have any tips or links dealing with integrating an LCD with the BS2? I
    am using an Alesis G8 (9-40-1381-C) driven by a Samsung KS0066U

    replies to my last post gave tips for the Hibachi HD 44780, anyone know about
    the Samsung? thanks in advance for all replies...

    Chances are that it uses an HD44780 compatible driver. If not, you'll have
    to find the driver specs and write some code.

    Don't worry, its works the same as a Hitachi HD 44780 ( I know because I
    have one0. Go to the parallax website and then stamp works to get some
    code to run it. Just make sure you connect everything properly, I'd
    suggest you put a 5k pot on the contrast line.

    Can u Connect A Color LCD to a BasicStampII Device if so where can I get

    I don't see why you couldn't but the problem is the stamp may not have the
    CPU and memory resources to deal with the complexities of a color display.
    Check out http://www.earthlcd.com/ they often sell color LCDs that were left
    over from cell phone production runs. I've been wanting to get one and try
    to interface it the stamp but I just haven't gotten around to it.
