Installing Python GPIO Library on BeagleBone Black Richard Hendrick Design Team 5 11/7/13 Executive Summary Learn how to properly install, update, and use one of the many Python GPIO libraries, Adafruit_BBIO. This library will allow the typical user with basic programming knowledge be able to develop a program that will create full interaction between the BeagleBone Black microcontroller and any circuit of their choosing that requires a toggling or high and low input. Introduction Microcontrollers can be and are used for many different applications today. One of the many sought after uses of the BeagleBone Black is to interface a circuit Which contains various multiplexers and selection chips with an easy to use computer-based graphical user interface. In order for all of this to happen, a main concern is to have the proper libraries installed and accessible so that a user can SSH into the board and make the appropriate changes to the program and change the outcome of the different user inputs. Overview Step one is going to go through the initial startup instructions of connecting the BeagleBone Black for the first time and installing the appropriate drivers to the host PC. Step two will explain how to use the board’s web interface to open an SSH connection through the GateOne SSH client. Step three gives the commands for logging in to the BeagleBone the first time. The actual installation instructions for Adafruit_BBIO are listed in step four, and a testing procedure is given in step five. Step One: Connecting the BeagleBone Black The BeagleBone Black ships with an Angstrom distribution operating system preinstalled that will work for the purposes of this guide. After plugging the board via USB in for the first time, go to beagleboard.org/GettingStarted to download and install the necessary drivers needed to
