  • I have tried with 2gb cards from SanDisk and Kingston and I have tried to format them with a variety of cameras, audio-recorders and disk utilities. In every instance I have verified that the card is indeed FAT16-formatted. I have even tried to partition the card so that the first partition is <64mb.
    I also know that the cards supports SPI as the file I try to create was at one point created, but it was empty and the card deemed corrupt by my card reader.
    I would be curious to know what cards if any people have gotten this shield to work with.

  • As much as I respect and admire Sparkfun, I have to say this product just plain sucks. I can’t get it to work with any microSD card and I think the “out of spec”-choice should have been clearly communicated in the product description.
    At least tell us which microSD cards this is supposed to work with.

  • I love you, Sparkfun. I didn’t get free stuff, but placed my order anyway a little later in the day. Now I wish you had a progress bar for the backlog. How far behind are you, and when do you expect to catch up?

  • I cobbled together this simple api to talk to the display in C:
    you’ll have to implement serialWrite yourself :-)
    It is true the firmware of the serial backpack is badly implemented and riddled with bugs, but I still find it useful and it’s open source so someone could easily fix it.

  • Perfectly simple and painless. Had it up and running in minutes.

  • Ah, that was incredibly painless. Thank you Brian Schmalz and Sparkfun.

  • The LED Matrix I recieved uses an Atmega 168 while the sample code seems to be written for Atmega 8 with an old version of the gcc-toolchain. I updated the self-control firmware example like thus:

No public wish lists :(
