💻 Installation

For detailed installation instructions, including dependencies and compilation steps, see INSTALLATION.md.

Quick Start

# Clone the repository
git clone https://github.com/AreteDriver/G13_Linux.git
cd G13_Linux

# Build the kernel module
make

# Install the module
sudo make install

# Load the module
sudo modprobe g13

---

📖 Usage

Basic Operation

Once the driver is loaded, the G13 device will be automatically detected and initialized:

# Check if device is detected
lsusb | grep "046d:c21c"

# Verify module is loaded
lsmod | grep g13

# Check kernel messages
dmesg | grep g13

Setting Up Macros

Configure macros using the character device interface:

# Set macro for G1 key (example: press Ctrl+C)
echo "macro G1 KEY_LEFTCTRL KEY_C" > /dev/g13-0

# Set macro for G2 key (example: type text)
echo "macro G2 type 'Hello World'" > /dev/g13-0

# List current macros
cat /proc/g13/macros

LED Control

Control the RGB LED backlight:

# Set LED to red (RGB: 255, 0, 0)
echo "led 255 0 0" > /dev/g13-0

# Set LED to blue
echo "led 0 0 255" > /dev/g13-0

# Turn off LED
echo "led 0 0 0" > /dev/g13-0

LCD Display Management

Control the 160x43 pixel monochrome LCD:

# Display text on LCD
echo "lcd_text 'G13 Active'" > /dev/g13-0

# Load bitmap image to LCD
./scripts/load_lcd_image image.pbm /dev/g13-0

# Clear LCD
echo "lcd_clear" > /dev/g13-0

---

⚙️ Configuration

Profile-Based Configuration

Create profile scripts for different applications:

# Load gaming profile
./examples/g13_gaming.sh

# Load productivity profile
./examples/g13_productivity.sh

# Load static configuration
./examples/g13_static.sh

Automatic Profile Switching

Configure automatic profile switching based on active window:

# Using udev rules
sudo cp udev/99-g13.rules /etc/udev/rules.d/
sudo udevadm control --reload-rules

# Using window manager hooks
./scripts/setup_autoswitch.sh

---

📚 Examples

Example 1: Static Configuration Profile

#!/bin/bash
# examples/g13_static.sh - Basic static configuration

# Set LED to green
echo "led 0 255 0" > /dev/g13-0

# Configure common macros
echo "macro G1 KEY_LEFTCTRL KEY_C" > /dev/g13-0  # Copy
echo "macro G2 KEY_LEFTCTRL KEY_V" > /dev/g13-0  # Paste
echo "macro G3 KEY_LEFTCTRL KEY_Z" > /dev/g13-0  # Undo

# Display status on LCD
echo "lcd_text 'G13 Ready'" > /dev/g13-0

Example 2: Gaming Profile

#!/bin/bash
# Configure WASD on analog stick
echo "stick_mode wasd" > /dev/g13-0

# Set red LED for gaming
echo "led 255 0 0" > /dev/g13-0

# Bind weapon keys
echo "macro G1 KEY_1" > /dev/g13-0  # Weapon 1
echo "macro G2 KEY_2" > /dev/g13-0  # Weapon 2
echo "macro G3 KEY_R" > /dev/g13-0  # Reload

Example 3: Multimedia Control

#!/bin/bash
# Media control setup
echo "macro G1 KEY_PLAYPAUSE" > /dev/g13-0  # Play/Pause
echo "macro G2 KEY_NEXTSONG" > /dev/g13-0   # Next Track
echo "macro G3 KEY_PREVIOUSSONG" > /dev/g13-0  # Previous Track
echo "macro G4 KEY_VOLUMEUP" > /dev/g13-0   # Volume Up
echo "macro G5 KEY_VOLUMEDOWN" > /dev/g13-0 # Volume Down
