ESP32_USB_STREAM is an Arduino library designed to support USB UVC + UAC host driver for ESP32-S2/ESP32-S3. It supports read/write/control multimedia streaming from usb device. For example, at most one UVC + one Microphone + one Speaker streaming can be supported at the same time.
ESP32_USB_STREAM encapsulates the component from the Espressif Components Registry. It is developed based on arduino-esp32 and can be easily downloaded and integrated into the Arduino IDE.
- Only support for ESP32-S2 and ESP32-S3 SoCs.
- Support video stream through UVC Stream interface.
- Support microphone stream and speaker stream through the UAC Stream interface
- Support volume, mute and other features control through the UAC Control interface
- Support stream separately suspend and resume
| Driver | Version |
|---|---|
| usb_stream | 1.4.0 |
For information on how to use the library in the Arduino IDE, please refer to the documentation for Arduino IDE v1.x.x or Arduino IDE v2.x.x.
| Name | Version |
|---|---|
| arduino-esp32 | >= v2.0.14 |
