* Pressing the boot button can switch the display resolution.
* For better performance, please use ESP-IDF release/v5.0 or above versions.
* Currently only images with a resolution smaller than the screen resolution are displayed
* When the image width is equal to the screen width, the refresh rate is at its highest.
## Hardware
* An ESP32-S3-BOX-3 development board with 320*240 LCD.
* A [USB camera](https://docs.espressif.com/projects/espressif-esp-iot-solution/zh_CN/latest/usb/usb_stream.html#id1) (Can be connected to USB port or Expansion Connector).
* A USB Type-C cable for Power supply and programming (Please connect to UART port instead of USB port)
* A USB Type-C cable for power supply and programming.
* A USB camera (Can be connected to USB-A port or expansion connector).
Note:
* While flashing, ensure that you connect the USB Type-C cable to the ESP32-S3-BOX-3. Once flashing is complete, connect the USB camera to the ESP32-S3-BOX-DOCK USB-A port, and switch the USB Type-C cable to the ESP32-S3-BOX-DOCK for regular usage. This ensures proper power supply to the USB camera.
* Error message with `A fatal error occurred: Could not open /dev/ttyACM0, the port doesn't exist`: Please first make sure development board connected, then make board into "Download Boot" mode to upload by following steps:
1. keep pressing "BOOT(SW2)" button
2. short press "RST(SW1)" button
3. release "BOOT(SW2)".
4. upload program and reset
>**Note: The USB camera used in this demo has some limitations.The USB camera must be compatible with `USB1.1` full-speed mode and support `MJPEG` output, for more details, please see the [USB Stream User Guide.](https://docs.espressif.com/projects/espressif-esp-iot-solution/en/latest/usb/usb_stream.html)**
## Known Issues
* Error message with `A fatal error occurred: Could not open /dev/ttyACM0, the port doesn't exist`. Please first make sure development board connection, then make board into "Download Boot" mode to upload by following steps:
1. Keep pressing "BOOT" button.
2. Short press "RST" button.
3. Release "BOOT".
4. Upload program and reset.
* Please use the USB-C port on the main unit to flash firmware. Once flashing is complete, connect the USB camera to the `ESP32-S3-BOX-DOCK` USB-A port, and switch your USB cable to the USB-C port of the `ESP32-S3-BOX-DOCK`. **Please note don't connect the USB camera while flashing the MCU.**
* The USB-C port on the `ESP32-S3-BOX-DOCK`only support `5 V` power input, which ensures proper power supply to the USB camera. **Please do not use it to flashing firmware**.
* For log debugging, please access the serial connection by a standard `USB-To-TTL` device through the 12-pin female header of the `ESP32-S3-BOX-DOCK` with `U0TXD` and `U0RXD`.
The result after the demo is correctly programmed and connected is as follows：
