Now I got the example to work. It was only a few changes in the code , and 2 extra wires My project is to make a mp3 player by 2 shields: "FEZ Music Shield", and "SD card shield for Arduino V2.1". If anyone is interested, I can post the code here on the page, when it is ready.
I have just upgraded from arduino-0017 to arduino-0018. (Linux 32bit). I use to load a sketch in my batch-file as "./auduino my-skecth.pde". This do not work anymore. Do anyone know how to tell the arduino program to load a specific pde on startup
