Morse Code Encoder/Decoder

A 64-bit Linux assembly program written in NASM that converts text to Morse code and Morse code to text. This program supports uppercase letters (A-Z), numbers (0-9), common punctuation (.,?!), and spaces between words.

Features

• Text to Morse Conversion: Converts plain text (letters, numbers, punctuation) to Morse code, using '/' to represent spaces between words.
• Morse to Text Conversion: Decodes Morse code back to plain text, handling word spaces marked by '/'.
• Interactive Menu: Simple command-line interface with options to encode, decode, or exit.
• Input Validation: Handles invalid inputs gracefully with error messages.
• Efficient Design: Optimized for 64-bit Linux using NASM assembly for low-level performance.

Requirements

• Operating System: 64-bit Linux distribution
• Assembler: NASM (Netwide Assembler)
• Linker: GNU ld (part of binutils)
• Build Tools: make (optional, if using the provided Makefile)

Installation

1. Clone the repository:

   git clone https://github.com/<your-username>/morse-translator.git
   cd morse-translator

2. Assemble and link the program:

   nasm -f elf64 morse_translator.asm -o morse_translator.o
   ld morse_translator.o -o morse_translator

Usage

1. Run the program:

   ./morse_translator

2. Follow the menu prompts:

   • 1. Text to Morse: Enter text (e.g., "SOS HELP") to get Morse code output (e.g., "... --- ... / .... . .-.. .--.").
   • 2. Morse to Text: Enter Morse code with spaces between letters and '/' for word spaces (e.g., "... --- ... / .... . .-.. .--.") to get text output (e.g., "SOS HELP").
   • 3. Exit: Terminates the program.

Example Interaction

Morse Code Encoder/Decoder

1. Text to Morse
2. Morse to Text
3. Exit
Enter choice: 1

Enter input: HELLO WORLD

Output: .... . .-.. .-.. --- / .-- --- .-. .-.. -..

1. Text to Morse
2. Morse to Text
3. Exit
Enter choice: 2

Enter input: .... . .-.. .-.. --- / .-- --- .-. .-.. -..

Output: HELLO WORLD

Notes

• Input Limitations:
  • Input text is limited to 255 characters.
  • Only uppercase letters, numbers, and specific punctuation (.,?!) are supported. Lowercase letters are automatically converted to uppercase.
  • Unrecognized characters are ignored during text-to-Morse conversion.
• Morse Code Format:
  • Letters are separated by spaces (e.g., ".- .-." for "AR").
  • Words are separated by '/' (e.g., ".- / -.." for "A D").
  • Invalid Morse codes are skipped during decoding.

Building from Source

Ensure NASM and GNU ld are installed. On a Debian-based system, you can install them with:

sudo apt update
sudo apt install nasm binutils

Then build using the commands above or the Makefile.
