AutoMorse

Automatic Morse Code Encoder for Raspberry Pi Pico

中文文档在这里
AutoMorse is an automatic Morse code encoding library designed for the Raspberry Pi Pico.
It can convert the input text message into Morse code and output it through GPIO (you can connect GPIO to other components such as relays to operate the wireless station).
This library is intended for radio amateurs and users who need automated Morse code sending functionality, and can also be used for teaching and demonstration.

Features

• Supports GPIO control: You can select any GPIO pin as a signal sender and indicator light.
• Adjustable sending speed: You can set the sending speed (in words per minute) according to your needs.
• Standard Morse Code Mapping: Built-in standard Morse code dictionary, supporting letters, numbers and common symbols.
• Error Handling: For invalid characters, an error is signaled.

How to Use?

Step 1: Download and Place the Library

Download the library file AutoMorse.py and put it into the lib folder under the Raspberry Pi Pico file directory.

Step 2: Import the Library

Call the library file in your main script:

from AutoMorse import AutoMorse

Step 3: Initialize the AutoMorse Object

Define the parameters for the Morse code transmission:

morse = AutoMorse(buzzer_pin, led_pin, wpm)

Here, buzzer_pin and led_pin are the GPIO pins for the buzzer and LED respectively, and wpm is the sending speed in words per minute.

Step 4: Convert and Send Morse Code

Convert the message you want to send into a list and process it using the library:

phrase = list(content) 
morse.Morse(phrase)

Here, content is the text message to be converted. The Morse method will handle the conversion and transmission.

Error Handling and Notes

• Ensure all characters in your message are valid Morse code characters. For invalid characters, the library will signal an error.
• If you encounter issues with GPIO control, double-check your pin connections and configurations.
