Utilities

The Utilities git repository is a set of helper apps for Ninja Blocks. The scripts are kept in /utilities/bin/

arduino_update

This script updates your Arduino by:

• Downloading the latest stable Arduino hex code.
• Calling setgpio to enable the pin on the Beagle that is attached to the ATMEGA reset pin on the Arduino.
• Calling setserial to enable the UART serial port for programming the Arduino.
• Calling avrdude and uploading the hex code to the board.

color

A tiny script that sets the color of the RGB Led on the Arduino.

• options are: red, orange, blue, green, and off.

document_config

This script prints out the configuration of the Beagle Bone including:

• The Ubuntu Config.
• A list of installed debian packages.
• A list of installed ruby gems.

fswebcam

Fswebcam is a light weight webcam snapshot grabber that's open source.

• Requires libgd2-xpm & libgd2-xpm-dev
• Available here: http://www.firestorm.cx/fswebcam/
• Command used by picture: fswebcam -q --no-banner --save /tmp/output.jpeg 2>&1

ninja_update

Ninja Update is intended to be run after a git pull. It runs all scripts in /utilities/update_scripts/*

picture

Picture takes an picture using fswebcam and outputs a base64 string. The idea is that it can be called from node.

reset_arduino

Call this script to reset your Arduino.

• reset_arduino must be run as root.

serialnumber

Returns the Beaglebone's Serial Number.

• Serialnumber (must be run as root).

setgpio

• This sets pin 7 on the Beaglebone to GPIO, allowing us to later reset the Arduino.

setserial

• This sets the MUX for the UART pins on the Beagle so we can speak serial to the Arduino.

wifi_status

• Returns 'up' if the Wi-Fi network is up.
• Returns 'down' if the Wi-Fi network is down.
