This month's issue of MagPi magazine: https://magpi.raspberrypi.org/issues/92
(PDF free to download) has a project to connect a Morse code keyer to a Raspberry Pi and then Python code to process the input. They use it to feed Twitter so you can tweet in Morse code, but of course you can modify the code to do anything.
