Finally my GY-80 boards are arrived from china , I'm still waiting for bluetooth modules but now I can start working.
I will try them with your code to test if they are working or faulty, then I will start to study your code and then modify it or write my own one.
I've downloaded last version from your repository (r11) and successfully imported the project into CCS.
How can I test if my setup is working after compiling the code? Have I to set something into project options?
These are the connections from Stellaris board to GY-80 board:
