BSP: Display USB HID Example
Overview
| This example demonstrates usage of the USB HID (keyboard, mouse or GamePad) with Board Support Package. |
|
How to use the example
Hardware Required
- Board ESP32-S3-USB-OTG
- connect 5V USB power supply to the left “USB DEV” connector
- connect USB keyboard/mouse to the right “USB Host” connector
Build and Flash
To build and flash the example for a specific {board} and {port}, use the following command:
idf.py -D SDKCONFIG_DEFAULTS=sdkconfig.bsp.{board} -p {port} flash monitor
Make sure the correct board name is set in the main/idf_component.yml file under the dependencies section.
