Some code to allow for interacting with Topre Realforce RGB keyboards. The software provided by the manufacturer only supports Windows.

This isn't intended to be a full replacement for the Realforce software - just some basic classes that can be used as building blocks.

1. Ruby 2.3+. Earlier versions of Ruby may work, but are not supported.
2. libusb 1.0.0 or greater. The old version 0.1 is not supported.

Add this line to your application's Gemfile:

gem 'rf_rgb'

And then execute:

$ bundle

Or install it yourself with:

$ gem install rf_rgb

require 'rf_rgb'

keyboard = nil
begin
 # .new without an arg will automatically find and initialize the first Realforce RGB keyboard it finds.
 # Keyboard cannot be used at this point, as it's owned by this program until .release_to_os is called.
  keyboard = RfRgb::Keyboard.new
  
  keyboard.effect_rainbow_wave
  # keyboard.effect_shooting_star("ff00ff", RfRgb::Protocol::INTERVAL_6)
  # keyboard.effect_pressed_key("aaeeff")
  # keyboard.disable_effect
  keyboard.brightness = RfRgb::Protocol::BRIGHTNESS_LOW
  keyboard.actuation_height = RfRgb::Protocol::HEIGHT_22
  keyboard.swap_caps_ctrl
  keyboard.save
ensure
  keyboard&.release_to_os
end

OR

require 'rf_rgb'

RfRgb::Keyboard.run_and_release do |keyboard|
  keyboard.effect_rainbow_wave
  keyboard.brightness = RfRgb::Protocol::BRIGHTNESS_LOW
  keyboard.actuation_height = RfRgb::Protocol::HEIGHT_22
  keyboard.swap_caps_ctrl
  keyboard.save
end

Additional examples can be found in the examples directory.

See lib/rf_rgb/keyboard.rb for effects and arguments, and lib/rf_rgb/protocol.rb for any needed constants.

On Ubuntu Linux at least, some udev configuration was necessary to be able to run as a non-root user, and prevent usbhid from taking the device over. If you're in that boat, try this:

1. create /etc/udev/rules.d/99-topre.rules with the following content:

   SUBSYSTEM=="usb", ATTRS{idVendor}=="0853", ATTRS{idProduct}=="013a", MODE="0666", GROUP="plugdev"
   ATTRS{idVendor}=="0853", ATTRS{idProduct}=="013a", RUN="/bin/sh -c 'echo -n $kernel >/sys/bus/usb/drivers/usbhid/unbind'"
   

2. Add your user to the plugdev group: sudo usermod -a -G plugdev $USER
3. (Probably) log out and back in, so the new group is applied to your user
4. Unplug and re-plug the keyboard into a USB slot.

Some effects have a User 1-3 setting in the Windows UI. It's not clear what these are actually for, and are mostly ignored in this module for now.

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.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
