Kevin Pearson e5193b5985 Implement device IO as a shared library 
Provide make targets and build configuration to create a shared object
for other systems/applications to use to control keyboard LEDs without
 the need for instantiating the g810-led process.

Provide make targets for installing library and development files into
environments, such as the current system or package builders.

Currently preserves precious behavior of building g810-led binary as
statically linked. Provides an alternative build target of "bin-linked"
which will create a dynamically linked variant.

Raw Blame History

Installation :

Build dependencies :

  • git
  • g++
  • make

Dependencies :

  • hidapi or libusb

hidapi vs libusb :

hidapi is a newer implementation but needs more testing.
hidapi is more responsive than libusb (~20ms vs ~150ms).
hidapi seem not work on CentOS, writing on hidraw is not allowed.
hidapi is recommended but if you encounter problem on your system, switch to libusb.

Installation by repos :

ArchLinux (aur) :
yaourt -S g810-led-git # with yaourt
pacaur -S g810-led-git # with pacaur

Installation of dependencies :

ArchLinux :
sudo pacman -S git gcc make hidapi # for hidapi
sudo pacman -S git gcc make libusb # for libusb
Debian :
sudo apt-get install git g++ make libhidapi-dev # for hidapi
sudo apt-get install git g++ make libusb-1.0-0-dev # for libusb
Fedora :
sudo dnf install git make gcc-c++ hidapi-devel # for hidapi
sudo dnf install git make gcc-c++ libusbx-devel # for libusb

Installation :

git clone https://github.com/MatMoul/g810-led.git
cd g810-led
make # for hidapi
make LIB=libusb # for libusb
sudo make install
make install-lib to install the libg810-led library.
make install-dev to install the libg810-led library and headers for development.

Building the library :

The library is built by default when running the make (default target "all").

To specifically build the library as a standalone component:
make lib

Update :

Same as install, but your profile and reboot files are preserved.

Uninstall :

sudo make uninstall

Boot profiles :

If your system use systemd, g810-led has 2 systemd units (g810-led and g810-led-reboot).
These 2 units set the keyboard profile on boot and reboot.
Profiles are stored in /etc/g810-led :

  • /etc/g810-led/profile
  • /etc/g810-led/reboot

Samples can be found in /etc/g810-led/samples.
