BS2PE - Help cant send to EEPROM

hey all im using a bs2pe and for some reason, it runs the code i last sent to it, but i cant reprogram it anymore.

im using a professional development board and editor 2.3.9 that seems to work with my other bs2s fine.

i have nothing else hooked to the stamp except fro what the board uses by default.

any ideas?

thanks!

    It's very very hard to break the EEPROM on the Stamp module and some kind of severe damage to the Stamp is the only thing that would prevent it from being programmed other than: Check that the Stamp is plugged in correctly and there's adequate power for the Stamp. The editor should be able to identify the Stamp model. Check your wiring between the PC and the Stamp. If the DTR line isn't working, the Stamp can't be reset by the PC and the editor won't recognize the Stamp and won't download a new program.

    thanks mike, all looks good... my other stamps are programmable with this board and cable...

    this goofy bs2pe does get reset by the editor, but after that it scans and finds nothing.

    It may be that the BS2pe was damaged at some point and that is causing the problem. You can contact us directly to get an RMA number to send it in for testing and we can determine what happened to it if you like. Please send an e-mail to support@parallax.com and include your customer purchase information. Take care.

    Hi,

    I have another question regarding the EEPROM. I have the same basic stamp. I am working on my college senior design and the i am kind of running out of programming memory. I was wondering if I can replace the EEPROM on the development board with another one that has a bigger memory.
    Thanks

    No. Even if you were to unsolder the existing EEPROM and substitute a larger capacity one, the Basic interpreter would not recognize the space.

    It's usually fairly easy to save on program space. There are often commonly used code sequences that can be turned into subroutines. There are often long DEBUG statements that can be shortened or eliminated. There are often simpler ways to do things that can save on space.

    The BS2pe has additional "slots" of program memory that can sometimes be used depending on the structure of your program. There's an article on multi-slot programming in the Nuts and Volts series of columns that goes into this in detail. I don't have a link handy.
