I was having the same problems as Tronico. But it seems Mike T's code from the page Ian W linked works fine. The code uses a new way of initialization:

Which is probably why the other code does not work. You probably bought a third party nunchuck (like I did from ebay, they're only $10).

Hey guys, I've been following this very helpful thread but haven't made much progress. I've figured out it's not detecting the card is in since I get STA_NOINIT and STA_NODISK from the MMC init function. I'm using the 012 arduino software.

I've measured the pins with a multimeter and I suspect one of the ground pins isn't connected quite right. So I was wondering how you guys have it hooked up? I bought just the SD card holder and stuck a breakaway thing with the side with the long pins going in to the holder and wires soldered to the short pin side as shown below. I'm using a seeduino which has a 3v3 switch and it's hooked according to the diagram in the OP.

edit>oh right and the question: how do you guys have your card holder hooked up? Is there a better way of doing it? I could have gotten the card holder with a pcb soldered on from sparkfun but it was $15 but I want to use it in a final pcb design too. If nothing works I guess I'll have to suck it up and buy that sd holder board.

Any help would be great!

Sweet Open Hardware Bank idea (followed the link on youtube)! I can really see how this can really get big quick. Wired just need to run another article on this and it can start snowballing like crazy.

If I didn't already buy all the parts for this sort of project I would invest in it too!

That's really nice. I had no idea the benefit of i2c until I hooked up my LCD. Even with the reduced 4 data pin this thing still requires 6 less pins. I wonder how much bigger the code size is?

Awesome work! It works really well too from the video. Looking forward to the parts list and code.
