📻 PiWave

PiWave is a Python module designed to manage and control your Raspberry Pi radio using the pi_fm_rds utility. It allows you to easily convert audio files to WAV format and broadcast them at a specified frequency with RDS (Radio Data System) support.

Features

• Converts audio files to WAV format.
• Broadcasts WAV files using the pi_fm_rds utility.
• Configurable broadcast frequency, PS (Program Service), RT (Radio Text), and PI (Program Identifier).
• Supports looping of playback.
• Detailed logging for debug mode.

Hardware Installation

To use PiWave for broadcasting, you need to set up the hardware correctly. This involves connecting an antenna or cable to the Raspberry Pi's GPIO pin.

1. Connect the Cable or Antenna:

   • Attach a cable or an antenna to GPIO 4 (Pin 7) on the Raspberry Pi.
   • Ensure the connection is secure to avoid any broadcasting issues.

2. GPIO Pinout:

   • GPIO 4 (Pin 7) is used for the broadcasting signal.
   • Ensure that the cable or antenna is properly connected to this pin for optimal performance.

Manual Installation

To install PiWave manually, follow these steps:

1. Clone the repository and install:

   pip install git+https://github.com/douxxu/piwave.git --break-system-packages

2. Dependencies:

   PiWave requires the ffmpeg and ffprobe utilities for file conversion and duration extraction. Install them using:

   sudo apt-get install ffmpeg

3. PiFmRds:

   PiWave uses PiFmRds to work. Make sure you have installed it before running PiWave

Usage

Basic Usage

1. Importing the module:

   from piwave import PiWave

2. Creating an instance:

   piwave = PiWave(frequency=90.0, ps="MyRadio", rt="Playing great music", pi="ABCD", loop=True, debug=True)

3. Sending files for playback:

   files = ["path/to/your/audiofile.mp3"]
   piwave.send(files)

4. Restarting playback:

   piwave.restart()

5. Stopping playback:

   piwave.stop()

Configuration

• frequency: The broadcast frequency in MHz (default: 90.0).
• ps: Program Service name (up to 8 characters, default: "PiWave").
• rt: Radio Text (up to 64 characters, default: "PiWave: The best python module for managing your pi radio").
• pi: Program Identifier (up to 4 characters, default: "FFFF").
• loop: Whether to loop playback of files (default: False).
• debug: Enable detailed debug logging (default: False).

Error Handling

• Raspberry Pi Check: The program verifies if it is running on a Raspberry Pi. It exits with an error message if not.
• Root User Check: The program requires root privileges to run. It exits with an error message if not run as root.
• Executable Check: The program automatically finds the pi_fm_rds executable or prompts the user to manually provide its path if it cannot be found.
