-====== Hooking up Pixy to a Beaglebone Black ======
-====== 1. Introduction ======
-The following procedure outlines steps to build the 'hello_pixy' example on a BeagleBone Black using the Debian Linux Distribution (Debian Image 2014-05-14). The 'hello_pixy' example is a simple program that demonstrates how to read blocks and send commands to the Pixy over USB like the PixyMon application.
-You will need:
-  * BBB with Debian Linux Distribution installed to the eMMC
-  * USB Hub with at least three ports
-  * Pixy updated to the latest firmware (1.0.2)
-  * libpixyusb version is 0.2
-The Debian Linux distribution for the BeagleBone Black is available from the BeagleBoard website here: http://beagleboard.org/latest-images/\\
-A procedure for flashing the BeagleBone Black can be found here: https://learn.adafruit.com/beaglebone-black-installing-operating-systems/flashing-the-beaglebone-black
-====== 2. Procedure ======
-===== 2.1. BeagleBone Black Hardware Setup =====
-==== 2.1.1. Using a USB hub, connect your keyboard, mouse, and Pixy to the BeagleBone Black. Using an Ethernet cable, connect your BeagleBone Black to the internet. Connect a video display to the BeagleBone Black using an HDMI cable. Power up the BeagleBone Black using either a USB cable or the 5V barrel connector. ====

-In the terminal window type:
-''%%git clone https://github.com/charmedlabs/pixy.git%%''
-===== 2.4. Build and install libpixyusb =====
-==== 2.4.1. Build the library ====
-In the terminal window type:
-''%%cd pixy/scripts%%''\\
-''%%./build_libpixyusb.sh%%''
-==== 2.4.2. Install the library ====
-In the terminal window type:
-''%%sudo ./install_libpixyusb.sh%%''
-===== 2.5. Running the 'hello_pixy' example =====

-In the terminal window type:
-''%%cd ../build/hello_pixy%%''\\
-''%%sudo ./hello_pixy%%''
-The output should look like something below:
-''%%Hello Pixy:%%''\\
-''%% Example Version: 0.3%%''\\
-''%% Pixy Firmware Version: 1.0.2%%''\\
-''%%Detecting blocks...%%''\\
-''%%[sig: 1 w: 11 h: 17 x:149 y: 46]%%''\\
-''%%[sig: 1 w:  9 h: 21 x:148 y: 46]%%''\\
