Common functions for interacting with Microstack products.

Contains some core helper functions and pure Python drivers for accessing GPIO pins, SPI and I2C buses.

Currently in active development. Still need to experiment with SMBus for Python 3.

Make sure you are using the latest version of Raspbian:

$ sudo apt-get update
$ sudo apt-get upgrade

Install microstackcommon for Python 3 with the following command:

$ sudo apt-get install python3-microstackcommon

You will also need to set up automatic loading of the SPI kernel module which can be done with the latest version of raspi-config. Run:

$ sudo raspi-config

Then navigate to Advanced Options, SPI and select yes.
