    Errata

    There was a small typo in experiment 4. 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 codes in Experiment 4 are now correct. I left the print out for anyone interesting in viewing the register before and after the bits are shifted. It's currently commented out with a #. Just remove it to view.

    Nevermind. I figured it out.
