mpetovello 0:3bffc1862262 6 * Description :
mpetovello 0:3bffc1862262 7 * This library is created for ENGO 333 class. The inertial sensor needs to be
mpetovello 0:3bffc1862262 8 * mounted on the mbed Application Board. The I2C connection is automatically
mpetovello 0:3bffc1862262 9 * set to p28 (SDA) and p27 (SCL).
