Chris Morgan c1781bc4cb Add support for led_classdev_mc via sysfs 
Update the LinuxLEDController to support multicolor LEDs defined by
the Linux kernel. For multicolor LEDs Linux exposes a single
brightness which allows a range of 0 (off) to 255 (max) and a multi_intensity
value that accepts multiple channels of colors. This current implementation
assumes that there are 3 multi_intensity channels between 0 and 255.

https://docs.kernel.org/leds/leds-class-multicolor.html

Note that for now in Linux the brightness value doesn't so much affect
the brightness of the LED as it does apply a coefficient to the individual
channel intensities. For now hard code the brightness to 255 and simply
adjust the intensities to alter the color.

This change should keep the existing sysfs code path as-is and only attempt
to use this new method when a led_rgb_path is present in the config file.

For reference, my OpenRGB.json has the following lines:
`    "LinuxLEDDevices" : {
        "devices": [
            {
                "name": "Fan LED 1",
                "rgb_path": "/sys/class/leds/rgb:programming-0/"
            }
        ]
    }`

Pipeline Status

One of the biggest complaints about RGB is the software ecosystem surrounding it. Every manufacturer has their own app, their own brand, their own style. If you want to mix and match devices, you end up with a ton of conflicting, functionally identical apps competing for your background resources. On top of that, these apps are proprietary and Windows-only. Some even require online accounts. What if there was a way to control all of your RGB devices from a single app, on Windows, Linux, and MacOS, without any nonsense? That is what OpenRGB sets out to achieve. One app to rule them all.

WARNING!

This project interacts directly with hardware using reverse engineered protocols. While we do our best to make sure we're sending the right data, there is always some risk in sending data to hardware when we don't understand exactly how that hardware works. There have been issues in the past with certain hardware getting damaged/bricked and we have either disabled or fixed the offending code. That said, with OpenRGB always changing and the landscape of RGB devices being of widely varying quality, we can't guarantee it won't happen again. By installing and using OpenRGB you accept this risk.

How-Tos and FAQs

Support OpenRGB

  • OpenRGB is a project I created to solve a problem I had with the RGB ecosystem. My goal isn't to make money off of this project. That said, people have requested to donate, and donations allow me to buy more RGB stuff to reverse engineer.
  • Donate via PayPal
  • Become a Patron (I'm not doing any Patreon-exclusive content, it's purely for donation)
  • Donate via Bitcoin: 1N83YPu7btXYadPS1neB9zX7X1QTdpyZQ

History of OpenRGB

  • OpenRGB is a continuation of OpenAuraSDK, which itself was created out of reverse engineering work done on the Keyboard Visualizer project. For a complete history of the RGB projects that led to OpenRGB's creation, see the History page.

Contributing

  • Want to contribute support for a new device? Check out the RGBController API page for documentation of how OpenRGB implements device control.
  • Want to create a new OpenRGB SDK client implementation? Check out the OpenRGB SDK Documentation page for documentation of how the OpenRGB SDK network protocol functions.
  • Please read the Contributing Guidelines before starting work on your new changes.
