Morse code bootup tune generator

[OZ5TN]

Evening folks,

I wanted to put my callsign in morse as a bootup tune in my new DM-1701, so I asked ChatGPT to write a script to help me out. It failed miserably, so I got really annoyed with it and decided to teach it a lesson by showing it how it's done

Here's the resulting script. If you don't have Python installed, you can run it online on this link and just change the morse_code string to whatever you want: Online Python.

Code: Select all

def morse_code_to_boot_tune(morse_code, pitch=38, speed=1):
    symbols = {
        '.': (1, 1),
        '-': (3, 1),
        ' ': (0, 3),
        '/': (0, 7)
    }
    tune = []
    gap = 0
    for symbol in morse_code:
        if symbol not in symbols:
            continue
        if gap:
            tune.append((0, gap))
        tone_length, gap = symbols[symbol]
        if (tone_length):
            tune.append((pitch, tone_length))
            

    return ','.join([f'{tone},{duration*speed}' for (tone,duration )in tune])

# Morse code for "CQ DMR"
# We use space to denote a gap between letters and slash for gaps between words.
morse_code = "-.-. --.-/-.. -- .-."
pitch = 38
speed = 2
tune_str = morse_code_to_boot_tune(morse_code, pitch, speed)
print(tune_str)

Output:
