Likewise... I have been trying to get this to work and have not heard a peek in testing.
I am using the sparkfun board pictured below. https://www.sparkfun.com/products/11125
1gb sandisk microSD
1 sound file on the card at 72kb.
FAT formatted on windows 7
File is named 0.ad4, and located in the root directory
I have tried wiring it up directly to 3v power, to the 3.3v and Vcc pads and touching the reset and play pins to ground... nothing
I tried using the arduino with this library as well, and have not seen any data on the serial monitor, nor any reaction from the board.
Would anyone with experience getting this to work consider writing an idiot helper post detailing exactly how to configure the board, leads, arduino code/libraries to get a hello world equivalent file to play?
Is there anyway to isolate whether the SD card is the problem vs a user error in wiring and configuring?
thanks
