ESP USB Bridge

The ESP USB Bridge is an ESP-IDF project utilizing an ESP32-S2 (or optionally, an ESP32-S3) chip to create a bridge between a computer (PC) and a target microcontroller (MCU). It can serve as a replacement for USB-to-UART chips (e.g. CP210x). Official reference can be found here.

Configuration

You can configure debugging tool using debug_tool option in “platformio.ini” (Project Configuration File):

[env:myenv]
platform = ...
board = ...
debug_tool = esp-usb-bridge

If you would like to use this tool for firmware uploading, please change upload protocol:

[env:myenv]
platform = ...
board = ...
debug_tool = esp-usb-bridge
upload_protocol = esp-usb-bridge

More options:

• Debugging options

• Upload options
