alt/i. And gott the same error.

    Hello Stampers


    While reprogramming a used BS2sx (there was a nearly 2kB program in slot 0)
    with a very simple test program (only 4 lines of code) I got an "eeprom
    verify error".

    The statue bar below became yellow and said "download failed".

    After retrying everything was ok.

    Somebody any idee what this caused?

    Thanks in advance

    Michel

    Hello Dave,

    >This sounds like a symptom of a BASIC Stamp that has been over written
    >to or has a damaged EEPROM. What four lines of code were you using?

    It's indeed a stamp I've used many times for experimental purpose, it's
    placed on a self designed experimental board and I often use it to test
    simple code.

    But in worst case, I think I have rewritten it for about 1000 times so it
    can't be "over written"



    The code I was trying to download:

    ' {$STAMP BS2sx}
    ' {$PBASIC 2.5}

    lus:

    PULSOUT 0,65535
    PAUSE 500

    GOTO lus:

    end

    I don't think this is to complicated for the BS2sx :-))

    Thx in advance,

    Michel

    Hello,

    I apologize; I had incorrectly read your first e-mail. Jon Williams had
    pointed out that this is most likely a communication issue between your
    BASIC Stamp and the PC. Make sure that you have shut down all software
    that uses a com port. If you have a PDA or a Palm Pilot, make sure to
    turn off the "Hot Sync" button.

    Regards,

    Dave

    Interestingly enough, today while playing around with the Emic, I
    had a strange glitch downloading code to the BS2. Several times I
    would start the download, get anywhere from 25% to 53% complete
    downloading and get an error that the hardware wasn't responding.
    It's the only time it happened, and it did it quite a few times in a
    row, sometimes working, sometimes not. Maybe it's just a glitch in
    the Matrix? ;-)
