Overview of this book

BeagleBone is a microboard PC that runs Linux. It can connect to the Internet and can run OSes such as Android and Ubuntu. BeagleBone is used for a variety of different purposes and projects, from simple projects such as building a thermostat to more advanced ones such as home security systems. Packed with real-world examples, this book will provide you with examples of how to connect several sensors and an actuator to the BeagleBone Black. You’ll learn how to give access to them, in order to realize simple-to-complex monitoring and controlling systems that will help you take control of the house. You will also find software examples of implementing web interfaces using the classical PHP/HTML pair with JavaScript, using complex APIs to interact with a Google Docs account, WhatsApp, or Facebook. This guide is an invaluable tutorial if you are planning to use a BeagleBone Black in a home automation project.

Setting up the hardware

This time, the hardware setting is not very tricky since we just need two I2C chips to get the basic environment data for our weather station, while all the complexity is in the software settings, since we need at least a 3.13 kernel to manage the sensors and a complete software toolchain to talk with the Google Docs system!

Maybe this is not the case with you, but my BeagleBone Black runs a kernel version 3.8 where some drivers are missing. That's why I decided to install a new distribution based on kernel release 3.13 on an external microSD so that I do not have to modify the default on-board eMMC settings.

In any case, just to set up the hardware, I can use the current running kernel where I can enable the I2C bus named I2C1 with the following command:

root@beaglebone:~# echo BB-I2C1 > /sys/devices/bone_capemgr.9/slots

If everything works well, you should see the following kernel activities on your board:

part_number 'BB-I2C1', version 'N/A'
slot #7: generic override...
