aluqard 0:3b83fc30bbdf 23 * @section DESCRIPTION
aluqard 0:3b83fc30bbdf 24 * This is a library for allowing the use of programs written for the Arduino
aluqard 0:3b83fc30bbdf 25 * with the mbed. This was started for use with the Gameduino shield Library.
aluqard 0:3b83fc30bbdf 26 * It is currently uncomplete and not fully tested, but I don't see myself spending time on it.
aluqard 0:3b83fc30bbdf 27 * See TODOs and check http://arduino.cc/en/Reference/HomePage for missing parts
