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). |
