Yes, that is the idea basically. I have some flashlights with a complicated single-pushbutton interface (https://anduril.click/). Rather than trying to remember all the crazy click combinations to activate different flashlight functions, I'm thinking of reprogramming the firmware to recognize commands in Morse code. I guess that is easier than off-the-air CW decoding, but on the other hand the CPU in the flashlight isn't very powerful. So I wondered if anyone here had wisdom about what I might be getting into. I will look at the Github repos. Thanks!
