Board Static Config Example

Overview

This example demonstrates how to statically load the display screen settings of development boards through esp_panel_board_supported_conf.h and esp_panel_board_custom_conf.h configuration files, and verify the configuration by displaying color bars and monitoring touch coordinates.

How to Use

Step 1. Install SDK and dependencies

Step 2. Configure the libraries

  • [Mandatory] ESP32_Display_Panel:

    • This example already has the esp_panel_board_supported_conf.h and esp_panel_board_custom_conf.h configuration files in the project directory. But no board configuration enabled by default, before compiling, please edit the configuration file according to your target board:

      • If using a supported board, edit the esp_panel_board_supported_conf.h file and set ESP_PANEL_BOARD_DEFAULT_USE_SUPPORTED to 1. Then uncomment the target board definition in the file
      • If using a custom board, edit the esp_panel_board_custom_conf.h file and set ESP_PANEL_BOARD_DEFAULT_USE_CUSTOM to 1. Then change other configurations as needed in the file

    • This example already has the esp_panel_drivers_conf.h configuration file in the project directory. Edit this file as needed.

    • see Board Configuration Guide for more information

  • [Optional] esp-lib-utils :

Step 3. Configure the example

Step 4. Configure Arduino IDE

  • Navigate to the Tools menu
  • Select the target board in the Board menu
  • Change the PSRAM option to OPI PSRAM if using ESP32S3R8 + RGB LCD, or Enabled if using ESP32P4 + MIPI-DSI LCD
  • Change the USB CDC On Boot option to Enabled if using USB port, or Disabled if using UART port. If this configuration differs from previous flashing, first enable Erase All Flash Before Sketch Upload, then it can be disabled after flashing.
  • Change other configurations as needed
  • see Configuring Arduino IDE for more information

Step 5. Compile and upload the project

  • Connect the board to your computer
  • Select the correct serial port
  • Click the upload button

Step 6. Check the serial output

  • Open the serial monitor and select the correct baud rate (like 115200)
  • Check the output logs

Serial Output

The following are the logs output when using the Espressif:ESP32_S3_LCD_EV_BOARD_2_V1_5 development board. The logs content may vary with different development boards or different configurations, and it is provided for reference only.
