Does anybody know how to address the "other" 8 characters on a std
Hitachi 1 x 16 Chars LCD.

Using the example from the parallax book i'm able to display some
text on the first part of the display but nothing happens on the
other block.

I tried to use the 128 + 64 in the char but this doesn't seem to work

Thanks!

    One line displays usually split the line in two, with the last half being
    addressed as a second line. Mine work OK by sending 254,192. The 254 tells
    the Hitachi that a command is to follow, and the 192 is the 2nd line
    command.

    Good luck,
    Ray McArthur

    I thought you were using a serial interface to your LCD. If you are running
    "LCD Interface-terminal" in the Stamp manual, the 254, 192 sequence is what
    you need, but I don't know offhand how to insert them into the code.

    Sorry,
    Ray McArthur

    No money for the backpack display, plain LCD with hitachi chip on it.

    Dear Hennie, (your name sounds very Dutch)

    I can send you a piece of code from a 2x 16 display, hooked up like
    example 1 in the stamp-1 manual. I use it for the stamp-II with
    succes.
    It means that I have hooked it up using the plain conection to the
    display (14 wires total).

    Jugo
