Soon I would be hearing messages by spies in exotic locations, possibly in an attic, wearing trench coats and fedoras tapping out their secret messages to their HQ, or more likely not. I had an idea that it may be possible using an interrupt routine and using it to look at the time between triggered interrupts. Attempting to design one was an opportunity to learn about detecting data patterns, try out some case build ideas I had as well as learn a bit more about Morse Code. It covers radio history, codes, electronics and programming.
I didn’t know how it was achieved but the puzzle of the design continued to percolate away in the back of my mind.Ī Morse code decoder has a lot of elements that interest me. I didn’t see the schematic or the code but I was very impressed that it was possible with relatively few components. Some time ago I saw a YouTube video about a Morse Code decoder that was based on a micro controller. I admire those that are able to send and interpret Morse code messages at high speed. I find the history of Morse code fascinating. Decoding recreated Morse code from the Titanic
