Possible change to blinka, need to specify scl/sda now.

Traceback (most recent call last):
  File "test.py", line 9, in <module>
    i2c = busio.I2C(frequency=400000)
TypeError: __init__() missing 2 required positional arguments: 'scl' and 'sda'

So I needed to add the following to the usage example

import board
i2c = busio.I2C(board.SCL, board.SDA, frequency=400000)

More of a hardware problem, but any idea on if the DS2482-800 supports parasitic power? All my reads are 85c I think my next step there is to pick up a DS2482-100

Thank you for reporting, this is my fault actually it's because I was running my unmerged PR adafruit/Adafruit_Blinka#496 and I forgot to translate back my example.

I'm sorry I don't know if the ds2482-800 supports parasitic power.
