ABElectronics ADC Pi 8-Channel ADC demo
Version 1.0 Created 09/05/2014
Version 1.1 16/11/2014 updated code and functions to PEP8 format

Requires python smbus to be installed
run with: python demo-read_voltage.py
================================================


Initialise the ADC device using the default addresses and sample rate,
change this value if you have changed the address selection jumpers

Sample rate can be 12,14, 16 or 18
