G13 Layout

G13 Layout Skill

Interactive tool for positioning G13 button overlays on the device image.

Usage

/g13-layout                    # Open position editor
/g13-layout --export           # Export to g13_layout.py
/g13-layout --verify           # Verify current positions

Process

1. Launch the calibration tool

   cd /home/arete/projects/G13_Linux
   python3 tools/g13_calibrate.py
   

2. Click on button corners

   • Click top-left of each button
   • Tool records coordinates
   • Preview shows button overlay

3. Export positions

   • Generates g13_layout.py code
   • Copy to resources/g13_layout.py

Button Order

Click buttons in this order for organized output:

1. M1, M2, M3, MR (M-key row)
2. G1-G7 (Row 1)
3. G8-G14 (Row 2)
4. G15-G19 (Row 3)
5. G20-G22 (Row 4)
6. LEFT, DOWN, STICK (thumb area)

Verification

After updating positions, verify with:

python3 -m src.g13_linux.gui.main

Check that all buttons align with physical button locations in the image.
