Data storage

Does anyone know how to use the Read and Write commands? Or is there
any other way to store data with the BS2 even after power is removed
from the chip?

    At the risk of sounding like a broken record ... ALL of our commands are
    documented in the manual that you can download from our web site at NO
    CHARGE.

    What ISN'T in the manual [noparse][[/noparse]but is in the Beta docs] is how READ and WRITE work
    in PBASIC 2.5:

    * Both work with word variables

    WRITE location, Word wordVar
    READ location, Word wordVar

    * You can use multiple variables in one statement:

    WRITE location, var1, var2, var3....
    READ location, var1, var2, var3....

    And, of course, you can throw the Word modifier into the multi-variable
    version.

    If you don't have enough onboard EEPROM for your needs, you can always attach
    an I2C or other EEPROM with the Stamp. It's easy to do and only takes a
    couple pins.

    Group,
    Has anyone any information on interfacing a standard 31/2'"
    floppy drive to a stamp for
    Data Logging? The application requires physically moving
    data from the unit to a pc.

    Anyone?

    You didn’t mention anything about your application, budget, etc.

    Here is a link to a datalogger designed to work with a CompactFlash card
    and a PC compatible file system.

    I think a complete starter kit runs about $299.

    There have been some threads about serial EEPROMs for data storage.

    Did you know that if you open your data logging program in Hyperterminal and
    capture the data to an Excel file, you can generate a file with 65535
    rows - that's 65535 data readings - and 231 columns - that's 231 channels.
    That adds up to 15MB of data storage.

    Data coming from a remote location? Use an RF link.

    Just a thought.
