    Download what?

    I was aware of some raw data use of an SD card, which is basically using one as a large EEPROM.
    Has anything else happened? I’m sure PBP could do a FAT32 filesystem, but not sure how any PBP supported chips would go fitting it, and a useful program as well.

    I'm using Parallax's memory stick datalogger device. It allows to write/read to USB flash drives.

    I gave up and am storing the data on an external 2 Mb EEPROM, then downloading it via USB. I never conquered the mysterious SD Card.

    SD card filesystems are quite large. I’m not even sure one would fit on any PBP supported devices.

    This looks like a shrill account though, in any case.

    I used one few years ago on PIC18F2550.

    It uses about 13KB. So there is 19KB Left for user code.
