The Projectify Ruby library provides convenient access to common functionality of NEC-made projectors for applications written in the Ruby language. It uses the ASCII character interface across the local area network.
Although NEC projectors often have a web interface available to perform similar functions, this library allows the same command to be broadcast to multiple projectors, thereby allowing all specified projectors to stay in sync.
See the docs folder of this repository for API information. Specifically, the common_ascii_e-r1.pdf provides the best reference.
- Ruby 2.0+.
Add the following to your Gemfile:
gem 'projectify', git: "git://github.com/setonparish/projectify"require 'projectify'
# configure projectors addresses
Projectify.configure do |config|
config.projector_addresses = ["127.0.0.50", "127.0.0.99"]
end
# send command to multiple projectors
broadcaster = Projectify::Broadcaster.new
broadcaster.call(:power_off) # { "127.0.0.50" => ">ok", "127.0.0.99" => ">ok" }
broadcaster.call(:power_on)
broadcaster.call(:power_status)
broadcaster.call(:shutter_open)
broadcaster.call(:shutter_close)
# check status on multiple projectors
broadcaster = Projectify::Broadcaster.new
broadcaster.all?(:powered_on?)
broadcaster.any?(:powered_off?)
broadcaster.all?(:power_transitioning?) # warming or cooling, but not yet in final state
broadcaster.all?(:shutter_open?)
broadcaster.any?(:shutter_close?)After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
