    Errata

    There was a small typo in the section called "Plot Sensor Data." The Python code shifted the bits too much on the temperature register:

    .
    .
    .
    temp_c = (val[0] << 4) | (val[1] >> 5)
    

    The correct number of bits that should be shifted is 4 bits:

    .
    .
    .
    temp_c = (val[0] << 4) | (val[1] >> 4)
    

    The example is now correct.
