g11-macro-keys

Library that models the USB/HID interface for the Logitech G11 Keyboard's macro keys.

This was primarily written for use within g11-macro-daemon, but you may check out the examples to see how you could build your own weird stuff on top of this library.

Key Layout

The macro keys interface covers:

  • 18 'G' keys
  • 3 'M' keys - each has its own LED
  • 1 'MR' key - has its own LED
  • 1 Backlight key
  (M1) (M2) (M3)  (MR)   ...   (💡)
