LMK (Lyn Mechanical Keyboard) WORK IN PROGRESS

LMK is a "smart" mechanical keyboard built using a raspberry pi zero.

This project is a work in progress. Currently I have a working prototype keyboard that sends keystrokes, runs arbitrary code, moves the mouse using a joystick, and generally does keyboard stuff.

Software

LMKLib is a software suite that sets up a RPI Zero as a "smart" keyboard. It is made up of 3 major parts:

• Usb Gadget
  • Configures the libcomposite linux module. Turns the rpi into a usb HID, ethernet adapter, and MIDI controller.
• Hid-Interface
  • Abstracts the hid devices created by the linux kernel so that multiple programs my interface with them at once.
• Key-Server
  • Translates the GPIO into a keyboard layout that can be customized and controlled through RPC

The software suite functionality:

• json defined keyboard layouts
• runtime tweaking of keyboard settings through variables
• a module system that supports python and rust
  • GPIO drivers
  • Key functionality expansion
  • custom HID outputs
• arbitrary code execution
• ethernet adapter emulation
  • direct ssh between the host and keyboard
• MIDI
  • acts as a usb midi controller
• RPC
• basic graphical interface

The repo of LMKLib can be found here

There are also 2 scripting languages designed to program keyboard macros:

• Ducky
  • a lazy Ducky Script interpreter
• Bork
  • a terse keyboard scripting language
