Best of all, the controller exposes a very simple I2C-based interface which is easy for a small-board computer like the Raspberry Pi or BeagleBone Black to access. This guide will show you how to install and use the Adafruit Python LED backpack library for driving LED backpack displays from a Raspberry Pi or BeagleBone Black!
Before you get started be sure to read the LED backpack guide to familiarize yourself with the assembly and basic usage of the backpack displays. You will also want to be familiar with connecting to and using a Raspberry Pi or BeagleBone Black's Linux command line. Finally, make sure your Raspberry Pi is running the latest Raspbian or Occidentalis operating system, or your BeagleBone Black is running the official Debian or a Debian-based operating system like Ubuntu.
