A command-line utility for controlling lighting modes and key mappings on NuPhy 75 keyboard from Linux.

• Set keyboard animation modes (with adjustable brightness and speed)
• Set individual key mappings
• Communicates directly with the keyboard via USB HID

./nuphy_linux --set-mode <mode_index> <brightness> <speed>
./nuphy_linux --set-key <key_name> <key_value>

The indexing is from left to right top to bottom

• --set-mode <mode_index> <brightness> <speed>
  Sets the lighting animation mode.

  • <mode_index>: Integer index of the animation mode (see below)
  • <brightness>: 0-4 (0=lowest, 4=highest)
  • <speed>: 0-4 (0=slowest, 4=fastest)

• --set-key <key_index> <key_value>
  Sets the value for a specific key.

  • <key_index>: Name of the key to set
  • <key_value>: Value to assign to that key

./nuphy_linux --set-mode 3 2 4
./nuphy_linux --set-key 2 F1

Each mode supports brightness and speed settings from 0 (lowest) to 4 (highest).
