  1. So, any details on the SD slot? Very early versions had it but it “wasn’t supported”. Which pins is the SD slot connected to?

  2. I just updated the Arduino website with the details for the new shield: http://arduino.cc/en/Main/ArduinoEthernetShield

    The SD card is on the SPI bus (pins 11, 12, and 13 on the Duemilanove), with pin 4 serving as the slave select line.

  3. Looks very good imho. Next step a RTC to make it the ultimate logshield. (please!)

    [not tested yet]
    For using the SDCARD one needs only a minimal change in the sdfat library: Open the file ArduinoPins.h and search for #define SS_PIN and change the pin number. Watch out to patch the right #define SS_PIN as it occurs multiple times.

    cheers,

  4. I’m a bit confused by this new shield – the updated documentation states:

    “The latest revision of the shield adds a micro-SD card slot, which can be used to store files for serving over the network.”

    Then it also states:

    “Note that because the W5100 and SD card share the SPI bus, only one can be active at a time.”

    Is it really possible to pull files from the SD card over the Ethernet? If so could a client/broswer pull a file using the following format: http://10.10.10.1/file-to-snag.txt?

    Thanks!
    Nate
