SD shield with Duemilanove

Hi Forum,

I'm trying to get the Libelium SD memory card shield running with a Duemilanove using SDuFAT. It looks like the card is not initializing. I've tried different 2GB cards.

The IDE is Arduino 0018 on an Acer Aspire 7740G running Linux - Ubuntu 9.10.
I have a temperature / humidity sensor logging away and would like to store the sample data.

The sketch loads and runs OK until it has to perform an actual card operation - then it just hangs. It will execute the 'H' (HELP) command quite happily but that simply lists the Terminal commands and does not access the card.

I had a check through the files and noticed in the mmc header file, 'mmc.h', the software was tested on a ATMega32. Also, in 'mmc.cpp', the pin assignments were wrong - I changed them from 2,3,4,5 to 10,11,12,13 but still no luck. I see later on in the same file there is further set-up declared but that is getting beyond my newbie capabilities with C++.

Does anyone out there have SDuFAT running on this hardware that could maybe point me in the right direction as to what I should do ?

All I need to do is store 512 byte data strings until a client requests the data, send it up and start logging again.

Will be very grateful for any help or advice.

Many thanks,

No wonder nobody wanted to reply to this one - cause of the problem was a faulty SD card shield.

Got a replacement from the supplier OK but it was faulty as well.

I contacted Libelium giving them an opportunity to comment before I updated this topic. That was about 2 weeks ago and no reply to date.The local supplier has discontinued the line.

In the meantime, I ordered an SD card logger shield from Adafruit last Thursday.
It was shipped on Saturday and arrived this (Wednesday) morning.
Unit was built over lunch-time and it's logging away like a professional - less than 6 days after ordering.

Moral of the story ?
Libelium obviously have very substandard production and QA control.
I will not buy from them again

On the other hand, the product from Adafruit is half the price, has an RTC, properly manages voltage correction, is a much sturdier design, has prototyping space and so on and so on.
