    This interface is the same for Arduino hardware i2c lib Wire, Arduino software i2c lib SoftI2CMaster and mbed hardware lib I2C.
    Choosing between them is done by compile time using flags, for mbed use USE_MBED_HARDWARE_I2C -flag.
    Note: This method doesn't allow multiple i2c busses to be used at same time.
