ABElectronics Delta-Sigma 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
