mBed RFM12B module Hello World example

The main purpose of this example was to implement the RFM12B module in order to be able to establish communication with the Moteino (arduino clone that uses the RFM12B).

In this example I’m able to test the communication between:

1) mBed -> mBed (2 RFM12B modules sharing the same mBed board)

2) mBed -> Moteino

3) Moteino -> mBed

Who/What is Moteino? (http://lowpowerlab.com/moteino/)
