- Basic Example:
This example demonstrates the process of subscribing to and publishing audio streams using Micro-ROS within the ADF framework.
The pipeline is as follows:
[codec_chip] ---> i2s_stream_reader ---> [Micro-ROS publisher]
|
v
[PC ROS2]
^
|
[Micro-ROS subscribtion] ---> i2s_stream_writer ---> [codec_chip]
This example runs on the boards that are marked with a green checkbox in the table. Please remember to select the board in menuconfig as discussed in Section Configuration below.
This example only supports IDF release/v5.2. By default, it runs on ADF's built-in branch $ADF_PATH/esp-idf.
This example requires ROS2 installed on your PC. It is recommended to install the Humble version.
If you are using Micro-ROS for the first time, please follow the setup instructions provided at micro-ROS ESP-IDF component.
The default board for this example is ESP32-S3-Korvo-2. If you need to run this example on other development boards, select the board in menuconfig, such as ESP32-Lyrat V4.3.
menuconfig > Audio HAL > ESP32-Lyrat V4.3
The dependencies for Micro-ROS are located in the components directory. If the local files do not contain the necessary library, please install it using the following command:
git submodule update --init --recursiveThis example requires a Wi-Fi connection for Micro-ROS communication. Configure the Wi-Fi information menuconfig > micro-ROS Settings:
menuconfig > micro-ROS Settings > WiFi Configuration > WiFi SSID
menuconfig > micro-ROS Settings > WiFi Configuration > WiFi Password
To configure the Micro-ROS agent information (IP address and port number), fill in the micro-ROS Agent IP and micro-ROS Agent Port:
menuconfig > micro-ROS Settings > (PC ROS2 IP) micro-ROS Agent IP
menuconfig > micro-ROS Settings > (PC ROS2 Port) micro-ROS Agent Port
It is recommended to enable PSRAM for stable operation:
menuconfig > Component config > ESP PSRAM > Support for external, SPI-connected RAM
If your development board uses an 8-line SPI RAM, configure the following:
menuconfig > Component config > ESP PSRAM > Support for external, SPI-connected RAM > SPI RAM config > Mode (QUAD/OCT) of SPI RAM chip in use (Octal Mode PSRAM)
It is also recommended to set the FreeRTOS clock frequency to 1000 Hz:
menuconfig > Component config > FreeRTOS > Kernel > (1000) configTICK_RATE_HZ
Build the project and flash it to the board, then run monitor tool to view serial output (replace PORT with your board's serial port name):
idf.py -p PORT flash monitor
To exit the serial monitor, type Ctrl-].
See ESP-IDF Programming Guide for full steps to configure and build an ESP-IDF project.
- The example requires the
Micro-ROSagent to be running and connected to the same Wi-Fi network as the development board. On the PC, you can start theMicro-ROSagent using the following Docker command:
# UDPv4 micro-ROS Agent
sudo docker run -it --rm --net=host microros/micro-ros-agent:humble udp4 --port [PC ROS2 Port] -v6
- The example provides a Python3.x script Audio_com_sub.py, which subscribes to ROS2 topics and plays AMR audio in real-time. Before running the script, please install the required libraries:
pyaudio,subprocess, andstruct. To install the libraries, use the following command:
pip install pyaudio subprocess struct
- When running the script, ensure to modify the ROS2 topic name according to your setup. This is crucial for subscribing to the correct topic for receiving audio data.
python3 Audio_com_sub.py
-
This example requires at least two boards to establish audio communication. Both boards will publish audio data to a ROS2 topic and subscribe to audio data from the topic for playback. Ensure both boards are correctly configured and connected to the same Wi-Fi network for communication. Set up Board 1 and Board 2 separately.
-
Board 1:
- Publishes audio data to the ROS2 topic:
Esp32_audio_data_1 - Subscribes to the ROS2 topic:
Esp32_audio_data_2
- Publishes audio data to the ROS2 topic:
-
Board 2:
- Publishes audio data to the ROS2 topic:
Esp32_audio_data_2 - Subscribes to the ROS2 topic:
Esp32_audio_data_1
- Publishes audio data to the ROS2 topic:
-

Once the example starts running, it will print the following:
