Here it is. It's some code I found here and modified / added some features.

The amp is the SparkFun TPA2005D1

Yes, I used the MP3 player shield with the Sparkfun amplifier.

Had some problems with it in the beginning, but managed to get it working.

I can poste the project if you want to.

Hello,

As the code here became a little hard to read and many asked for a complete solution.

Here it is ... with a tool to create the image array ...

Hello,

Did you try com2?

I would also use an event handler to see if data is available.

serialport.DataReceived += new SerialDataReceivedEventHandler( .... );

Hey Fabien,

I got this working with the I2C version and it's tested with 64 and 32 lines. Do you want to add it to your driver?
