Morse Code Audio Decoder
Trent Rolf
This embedded system is an audio Morse Code decoder meaning it "listens" to the audio
beeps, identifies dots, dashes, and spaces and uses that information do decide what
the message sender is trying to say. The input to the system is a microphone followed
by an amplifier which boosts the microphone signal to line level. The amplified signal
is fed into the ADC on the HCS12 microcontroller. The software running on the HCS12
decodes Morse Code signals received from the microphone and displays them on
the LCD display.
Here is the amazing video demonstration:
And the equally amazing system diagram:
