Disclaimer

This project is neither endorsed by, nor supported by, nor known to CoolerMaster. As usual with these sorts of projects, there is no warranty or liability should your device catch fire or eat your pet. Should that happen though, do feel free to file a bug report.

Device Support

cmmk_ctrl supports all the devices that are supported by libcmmk.

A current limitation is the missing last row of configurable LEDs on the MK750, the rest of the device should work as expected though.

Features

• Control over the predefined effects with the exception of Multilayer mode (supported in the library, but still lacks a somewhat intuitive UI)
• Manual mode
• Saving the profile configuration back to the device

Installation

If you're using Arch Linux, you can find cmmk_ctrl in the AUR. Depending on your AUR helper (e.g. yay), you can install it with:

yay -S cmmk_ctrl-git

Build Instructions

The build system is a bit messy because of the libcmmk depedency, cmmk_ctrl uses a standard makefile which compiles the dependency and then the main application. The PREFIX variable convention is respected.

Example:

# Use absolute paths so cmmk_ctrl can locate the image assets no matter where it's run
make PREFIX="$PWD/dist"
make PREFIX="$PWD/dist" install
