Crate morse_codec

Rust library for live decoding and encoding of morse code messages. Supports multiple embedded devices and operating systems by being no_std.

You can create messages by sending individual high and low signals in milliseconds to decoder, from the keyboard, mouse clicks, or a button connected to some embedded device.

Use the encoder to turn your messages or characters into morse code strings or create a sequence of signals from the encoder to drive an external component such as an LED, step motor or speaker.

Features

• Decoder
• Encoder

UTF-8 is not supported at the moment, but can be implemented behind a feature flag in the future.

The lib is no_std outside testing to make sure it will work on embedded devices as well as operating systems.

Modules

• decoder
  Live decoder for morse code that converts morse code to ASCII characters. Supports real-time decoding of incoming signals and decoding prepared morse signals.
• encoder
  Morse code encoder to turn text into morse code text or signals.
• message
  Message struct to hold decoded message or message to be encoded.

Enums

• MorseSignal
  Building block of morse characters.

Constants

• CHARACTER_SET_LENGTH
  Maximum number of characters in a mapping set of morse code to letters.
• DECODING_ERROR_BYTE
  If a decoding error happens, we put this character as a placeholder.
• DEFAULT_CHARACTER_SET
  Default international morse code characters. It includes English language letters, numbers and punctuation marks.
• FILLER_BYTE
  We use this character to fill message arrays so when we encounter this char it actually means there’s no character there.
• FILLER_CHAR
  Char version of the FILLER_BYTE coz why not? It’s mainly used while generating bytes from &str slices. A char which is utf-8 by default in Rust, can be more than one byte, turning chars into bytes if they’re ascii makes the code stable.
• MORSE_CODE_SET
  Internal representation of morse characters. It’s an array of length CHARACTER_SET_LENGTH.
• MORSE_DEFAULT_CHAR
  This corresponds to empty character ’ ’ which is the default character

Type Aliases

• CharacterSet
  Client code can use this type to construct a different character mapping to morse code and construct the decoder or encoder with this custom character set.
