Hi
i have a card initialization issue with my recently bought Arduino Wave shield from Adafruit
the error is
card.init failed
SD error
errorCode: 1
errorData: 0
however i am also unable to upload images as this error is displayed;
INFORMATION
The image file you tried to attach is invalid.

Re: Arduino Wave shield
Please post photos of the front and back of the shield. There is a 1-meg limit. If you resize to about 800x600 you should have no problems.

Re: Arduino Wave shield
Alright noted on the file size limit.
here are the pictures.
Thanks

Re: Arduino Wave shield
From what I can see, the solder looks very good. If you have an angled shot of the SD card holder we could better see how the surface mount solder joints have flowed onto the solder pads.
Try running the CardInfo example sketch from the SD library. That has a little more diagnostic output. Also, if you have a different SD card, try that.

Re: Arduino Wave shield
This is the serial output from the sketch
Initializing SD card...initialization failed. Things to check:
* is a card is inserted?
* Is your wiring correct?
* did you change the chipSelect pin to match your shield or module?
i have inserted an SDHC card 8GB as wel as changing the chipSelect pin to pin 10,
I'm also using arduino UNO as the main board.

Re: Arduino Wave shield
Hello
i have solved the card reading issue.
i realised that i forgot to insert the shield fully into the arduino main board.
I have also uploaded a test.wave file and attempted to play the file using daphc example found in WaveHc.
The serial monitor is as follows
Wave test!
Free RAM: 669
Using partition 1, type is FAT32
Files found (* = fragmented):
TEST.WAV
Playing TEST.WAV
................................

however there is no sound heard. The led on the main board is blinking.
please advise
Thanks in advance!

Re: Arduino Wave shield
That's good progress. Now to track down the sound:
If you have a set of earbud-type headphones, connect the shaft of the plug to ground (either via alligator clip or wrap some bare wire around it) Then use the tip to probe the resistor lead of R7. If you hear sound there, that tells us that the DAC is working properly.

Re: Arduino Wave shield
The problem has been remedied!
Apparently i found that the LCS to pin 2 copper has been burnt off the PCB.
So i attached a jumper wire to complete the circuit and now it's working.
But the sound heard is actually quite low. Is there any way i can amplify the signal to get a higher music output?

Re: Arduino Wave shield
The Op-Amp puts out about 1/4 watt max. You can add one of our Class-D amp modules to the output for a higher sound pressure level. https://www.adafruit.com/search?q=class+d&b=1
