CheekyPi

EventMachine friendly library for working with the DreamCheeky Webmail Notifier.

Installation

Add this line to your application's Gemfile:

gem 'cheeky-pi'

And then execute:

$ bundle

Or install it yourself as:

$ gem install cheeky-pi

Usage

require 'cheeky-pi'
require 'eventmachine'

light = CheekyPi.new.light

EventMachine.run {
  pi.light.color([0, 255, 0])
}

Multiple lights:

pi = CheekyPi.new
light1 = pi.lights[0]
light2 = pi.lights[1]
...
light1.failure
light2.success

Simple animation

CheekyPi.new.light.transition! [255, 0, 255]

Throb animation

#Perpetual throb animation, with a 10 second cycle period
CheekyPi.new.light.throb! [0, 255, 0], [0, 0, 255], 10

Fun with promises

light = CheekyPi.new.light
light.transition!(255, 0, 255).then {
  puts 'animation complete'
  light.throb! 10, [255, 0, 255], [255, 255, 255]
}

Build lights

case some_build_status
  when :build
    light.building
  when :failed
    light.failure
  when :successful
    light.success
  else
    light.off
end

Why?

My raspberry pi could not interact with the webmail notifier via libusb, so this gem depends instead on /sys/devices/*/red|green|blue courtesy of the usbled driver.

Additionally, I wanted (non-blocking) animation for use with a build monitoring tool.
