WAVE SHIELD SDHC card

[fprete]

Colleagues:

I have built the WAVE SHIELD and cannot get he SD card to initialize. All component pieces were purchased within the last few weeks from Adafruit, and I have done all suggested fixes three times, including altering the suggested sketch lines and library file. The card is a SanDisk 4 GB, formatted as suggested in the Adafruit instructions. Although this is not my final project, for testing purposes I pasted the uncompressed Pumkin Sound WAV files onto the card (and I also tried the other example files in the waveHC library top folder).

I continue to get the message "Error: Card init. failed! SD I/O error: 1, 0". In addition, although the dapHC.pde and other sketches compile, upload to the UNO, and run, I get an error message saying "Invalid library found in C:\Users\Dell User\Documents\Arduino\libraries\arduino: Missing 'author' from library."

Suggestions?

Thanks in advance, Dr. Prete

Please post photos showing your soldering and connections to the shield.

Here is a link to a photo of the shield:



Let me know if you see anything obviously wrong. I was a jeweler for ten years prior to getting my PhD in neurobiology ... so, I am relatively confident in my soldering. However, I may have made a component placement mistake.

I sincerely appreciate the help. I need to figure this out for a prototype on which I am working, and I am new in the electronics world. It's like starting school again.... at the 5th grade level. Fun but daunting.

Sorry. Here is the link:

From what I can see, the soldering looks very good in general. Pin 6 of the SD card holder does look a little suspect though. it is hard to tell from a vertical view. Make sure that the solder has wetted both the solder tab and the pad underneath: https://learn.adafruit.com/adafruit-gui ... face-mount

Thanks... I will re-solder it!

Exactly the same problem. What do "Error: Card init. failed! SD I/O error: 1, 0" and "Invalid library found in C:\Users\Dell User\Documents\Arduino\libraries\arduino: Missing 'author' from library" mean precisely?

[adafruit_support_bill]

The SD I/O error means it was not able to communicate with the card well enough to initialize it. This can be caused by soldering problems, timing incompatibilities, or in rare cases a defective card or card-holder. If you have a different card, give that a try.

If you run the SDInfo example in the SD library, it may give you a little more information about the nature of the problem.

I have not heard of the "Missing Author" problem. I do know that recent versions of the IDE have some new non-fatal errors related to "Invalid library". But most seem to be related to include-path confusion. The best place to ask that question is over at http://forum.arduino.cc/.

Thank you.

So, the SD I/O error I understand. This card works fine in the computer, just not in the shield. But I will try a new one. Is my only option to buy a new WAV shield and begin again?

The same message is returned by the SDInfo example.

The the "Missing Author" problem only shows up on one computer. Should I install the new IDE build (Sept 9th)?

[adafruit_support_bill]

Different SD cards have different timing characteristics. Personal computers have a lot more memory and horsepower so they can add lots of driver code to automatically adjust for that. The Arduino has limited resources, so the Arduino SD library is a relatively bare-bones implementation.

There is some capability to adjust the speed manually in the library. In the SDInfo sketch, you tcan try changing SPI_HALF_SPEED to SPI_QUARTER_SPEED in the call to card.init()

If it works with a different card, we can replace the first card. If not, we'll assume it is a hardware problem and we can arrange to replace the kit for you. Let us know how it works with the other card.

I'd give the new build a try.

[fprete]

Thanks!

I do not see the line "SPI_HALF_SPEED" in the SDInfo library sketch (and none of the words show up in a search). However, I did the other suggested changes in the pertinent sketches to alter the speed. (Some are listed in the sketch itself.) I tried the new card and that did not work either. I am puzzled. Could it be the hardware? Should I just get a new kit and give it another try?

Please contact [email protected] with a link to this thread and we can send you a replacement kit.

[fprete]

Will do. THANKS!

I seem to be having the same problem. Went through and resoldered everything. Changed cards and get an address of FF instead of 0 as the problem. Don't see the statement in the SDinfo sketch to change. Any other suggestions? This is for a project and it is due soon.

I got my replacement shield working. Ultimately, my problem was the hardware. The original kit was missing a component that I was overlooking. Otherwise, it all seems to be working as described for me.
