Installation

Currently, it is not possible to install without building from source.

Building from source

$ make

Loading the module

# make load

Unloading the module

# make unload

or

# rmmod opendragon

Usage

To change mouse configuration, you can send data manually or through the GUI or CLI application.

Sending data manually:

# echo -n "[mode] [red] [green] [blue] [brightness] [speed]" > /sys/bus/hid/devices/XXXX:YYYY:ZZZZ.XXXX/light_mode
# echo -n "[profile number]" > /sys/bus/hid/devices/XXXX:YYYY:ZZZZ.XXXX/profile

Where:

• mode is a number from 0 to 7 (Breathing, Rainbow, Full lighted, Wave, Go without trace, Reactive, Flash, Off)
• red is a number from 0 to 255, red channel
• green is a number from 0 to 255, green channel
• blue is a number from 0 to 255, blue channel
• brightness is a number from 0 to 2
• speed is a number from 0 to 8
• YYYY is vendor id
• ZZZZ is product id
• XXXX is interface number

Example:

# echo -n "2" > /sys/bus/hid/devices/0003:04D9:FC38.0003/light_mode
# echo -n "3 255 255 255 2 0" > /sys/bus/hid/devices/0003:04D9:FC38.0003/light_mode

This will switch to profile 3 (starting from zero) and change light mode to wave with brightness of 2 and speed of 0

Issues

• Functions are to big, break them into smaller functions
• UDEV rule doesn't work and I need help because I am not experienced with it

Contributing

Do you have a mouse that is not listed in supported mice? If so, file an issue to github page.
If you know how UDEV rules work please make a pull request.
