Controls the RGB lighting on some keyboards. Tested on Linux and FreeBSD, should work on other operating systems.

You can help to expand this list by providing information whether this software works correctly or not.
Known issues that require your help (please open an issue or pull request if you want to contribute):
- Remapping keys on the Ajazz AK33 and ISO boards is broken (all keys are shifted around)
- Setting the color of the ISO international key (Int_Key) in custom pattern mode is supported but not tested.
- Setting the USB report/poll rate on the Ajazz AK33 is untested
- Custom led patterns don't work correctly on the Redragon K550 Yama and K556 Devarajas
- Clone this repository or download a release
git clone https://github.com/dokutan/rgb_keyboard
cd ./rgb_keyboard
- Make sure you have libusb installed (on some distros (e.g. Ubuntu) you might need a dev package)
- compile and copy everything to the right place with (not required: replace the 4 with the number of cpu cores you have)
make -j4
sudo make install
- restart for the udev rule to take effect (without this you probably won't be able to use this softwate without root)
- install pkgconf
- compile with
make CC=clang++ -j4
- copy
rgb_keyboardto some directory in your $PATH, or execute it directly with
./rgb_keyboard
- Current limitations on FreeBSD:
- You need root privileges to use the program
- After the program has finished, the keyboard won't work and needs to be unplugged and plugged back in.

rgb_keyboard --list-keys arg

For the gui see the appropriate section below
Three individual profiles (1-3) are stored on the keyboard. Examples:
rgb_keyboard --active 2
to change to the second profile.
rgb_keyboard --profile 3 ⟨further options⟩
to apply settings to profile 3. Without this option profile 1 is used.
rgb_keyboard --brightness 5 --speed 2 --color 00ff00 --leds rain
to set a specific pattern.
rgb_keyboard --custom-pattern example.conf
to set a custom pattern from a file.
rgb_keyboard --keymap example.keymap
to set a custom keymap from a file.
Take a look at example.conf and example.keymap.
Similar to the config file, instead of a tab an equal sign and instead of a newline a semicolon is being used. Comments are not allowed. The string must end with a semicolon.
rgb_keyboard --custom-keys "key_name=color;key_name=color;"
In case you have multiple keyboards attached or you suspect a keyboard with a different vendor id or product id might be compatible, the keyboard can also be opened by specifying the bus number and device id. These can be found by running lsusb.
rgb_keyboard --bus ⟨bus id⟩ --device ⟨device number⟩ ...
On some systems libusb might no be able to properly detach the kernel driver, and the program will fail to open the keyboard. The --kernel-driver option skips this step and is intended for better compatibility.
Don't open usb interface 0 on the keyboard. This allows input to happen while settings are applied, and is primarily intended for scripting purposes. Because compatibility is untested, this needs to be specifically enabled with this option.
This is the replacement for the --ajazzak33 or -A option. This option expects true or false as an argument and toggles the control transfer mode to send data. Normally this shouldn't be required as the program attempts to use the right mode automatically.
A separate frontend written in Tcl/Tk exists, however not all features are implemented. Running the gui:
chmod +x rgb_keyboard-gui.tcl
./rgb_keyboard-gui.tcl
The gui is not copied to /usr/bin by default, you can do so manually.
