Memory Stick Datalogger

I was looking for any information that would give me a hint of how I can use the Memory Stick Datalogger by just using one or two pins from the Basic Stamp instead of using four (P11, P10, P9 and P8).· The reason of this is, I am working on a project that I need to download data to my basic stamp from a USB drive. I am just laoding data, NO sending, NO clearing, NO deletign or something else. Just loading.

Please help!!

    It takes pretty much the same amount of work to just download data as it takes to do anything else.

    You really do need the 4 I/O pins no matter what you do. The datalogger is quite fast and can easily
    overrun the Stamp, so the CTS# line is necessary for the SERIN to work properly. You might be able
    to get away with not using the RTS# line since the datalogger is faster than the Stamp and is unlikely
    to have a full buffer (so the Stamp would need to wait until it empties a bit).

    I have a group of subroutines that I use with a Vdrive2 ( which uses the same command set·as the datalogger ) and I only use the TX and RX lines. I have found this method to be very reliable.

    If you can provide a·few more detail on the amount of data you need to read and how you intend to use it with the Stamp then I·have some ideas that might get you started.
