hi,
my robot had eaten up all the memory from my stamp. i was wondering
if there is a way to connect two stamps together?

    Isn't the question more of the easiest way to get more memory ?

    Are you looking for RAM or EEPROM ?


    This is half a shameless plug for out stuff, but also a legitimate
    answer to the question of how to get more memory.

    The ChipCircuit-RTC, (real time clocks) have a small amount of
    battery backed NV RAM.

    The CC-RTC-1302 has the Dallas DS1302 chip that has 31 bytes of
    battery backed NV ram. SPI 3 wire.
    here is the Dallas data sheet
    http://www.maxim-ic.com/quick_view2.cfm?qv_pk=2685


    The CC-RTC-1307 has the Dallas DS1307 chip that has 56 bytes of
    battery backed NV Ram. I2C 2 wire

    Our newest offerings are serial EEPROM chips with 256k.

    We have a 256k ROM in the pipeline, should be available any day.

    A note here is that we offer sample code for the clock part of the
    clock chips buy have not addressed the RAM part.

    btw, if you visit the site, please fill out the survey. : )

    One thing that does pose a problem is that I don't think you can put
    program memory into any exteranl memory chips. if you want more
    program space, you have to use another Stamp unless you can offload
    varialbles or some such. And THAT is a great topic for a thread.

    Just upgrade your stamp to the BS2sx and enjoy 8 times the memory
    for programs along with 8 batches of variable space.

    Or BS2E for same amount of memory, or 2pe for 16 banks of memory. The Javelin has 32K of non-banked memory. There are lots of options. If you don't have the money, I'd suggest posting your code and ask people to help shorten it.
