This repo contains code to convert a physical Morse key into a USB keyboard, via a Teensy 3.2. This means you can plug the Morse key into any laptop or computer and use it in exactly the same way as a conventional keyboard, except you type in Morse and the characters appear on screen in English.
The keyboard currently supports lowercase letters of the alphabet from a-z and numbers 0-9.
Unrecognised characters are printed out as a dash, or "-".
Timings between characters and words are currently hardcoded in ms. This isn't hugely accurate since different operators will key at different speeds, but the hardcoded timings can easily be tweaked.
You'll need a Teensy 3.2 and a physical Morse key. I've configured my Teensy so one output from the Morse key is connected to Pin 7, and the other is connected to a ground pin.
