ok im a little bit of a nube but im ok at STAMP BS2.


Here is a link to the lcd im using

Im wondering what thay meen when thay say JPE

'If you are driving the display's "DATA_IN" line with 0v to 5v
'signals (which would be typical in a Basic Stamp application), be
'sure to close "JPE" on the LCD.


would·"JPE" be something in the basic stamp program or·like a button on the lcd

I dont exactly have the lcd yet so·I·cant·look·for buttons on it or any thing

OK heres what i got

    Hello,

    ·· Where are you getting that information about JPE from?

    Ive added an attechment of the .bs2 program that says

    'If you are driving the display's "DATA_IN" line with 0v to 5v
    'signals (which would be typical in a Basic Stamp application), be
    'sure to close "JPE" on the LCD.

    Ok this is great i found something else

    ' Program: COUNT.BS2 (Print-at-location with Stamp 2)
    ' This is the same as the previous program, but modified for the
    ' BS2 model. Since this program sends data to the Backpack
    ' at 9600 baud, be sure to install a jumper at BPS on the board.
    ' :::Note::: Make sure to connect the Backpack serial input to
    ' BS2 pin P0, not SOUT. SOUT is used for communication with the
    ' PC during programming/debugging.

    Chris,

    ·· There is no mention of a JPE (Presumably a jumper) in the manual you posted a link to.· Perhaps there was a revision to the device since that code was written, and it is no longer necessary.· You really should wait until you have the LCD and know if you have a problem.

    I read through the manual twice and cannot come up with JPE.

    It seems it could be a typo. Or, the software could have been created for another LCD and since it works with almost any serial LCD, they recommended it for this one [noparse][[/noparse]which has no JPE].

    Overall, it is a nice LCD with pretty good documentation. Still, you may have to create your own Pbasic program to drive it. The other program might just be useful as an intial test.

    I do a "Hello World" test and have the LCD blink so that I can run in for 24 hours as a burn in.
    That way I know it is working and I know I have software that will verify it is not broken if I late do something terrible to the LCD.
