I2C Device Summary
| Device | Model / Function | I2C Address | I2C Pins | Notes |
|---|---|---|---|---|
| Audio Codec | ES8311 | 7-bit I2C address 0x18 | GPIO7 / GPIO8 | Onboard audio capture and playback |
| Touch | Screen touch controller | 0x5D / 0x14 | GPIO7 / GPIO8 | BSP uses the esp_lcd_touch_gt911 driver, trying both addresses in sequence; RST / INT not connected |
| LCD Backlight | Backlight controller | 0x45 | GPIO7 / GPIO8 | Brightness register is 0x96 |
| Camera SCCB | External camera module | Depends on module | GPIO7 / GPIO8 | Shares bus with onboard I2C devices |
Precautions
- GPIO7 / GPIO8 are the onboard shared I2C bus. When connecting external I2C devices, confirm that the addresses do not conflict.
- GPIO45 is used for TF card power control, GPIO53 for the audio amplifier, and GPIO54 for ESP32-C5 communication reset; it is not recommended to use these as general‑purpose GPIO while the corresponding peripherals are active.
- The LCD reset, touch reset, and interrupt signals are not connected to ESP32-P4 GPIOs. The BSP does not use a dedicated GPIO for reset, and touch reads via polling.

Development Methods
Arduino-ESP32 provides development interfaces through the Arduino API. ESP-IDF provides a development toolchain including a compiler, debugger, and flashing tools, and supports finer-grained system configuration and control.
warning
This model already provides board definitions and peripheral examples based on Arduino-ESP32 3.3.11, and the adaptation scope is subject to the Working with Arduino. Complex examples and different panel combinations still need to be verified individually; when you need to use this model's BSP and the Brookesia comprehensive application, ESP-IDF development is recommended.
- ESP-IDF, short for Espressif IoT Development Framework, is Espressif's development framework for the ESP series of chips. It is developed using the C language, including a compiler, debugger, and flashing tool, etc., and can be developed via the command lines or through an integrated development environment (such as Visual Studio Code with the Espressif IDF plugin). The plugin offers features such as code navigation, project management, and debugging, etc. We recommend using VS Code for development. For detailed configuration steps, refer to the Working with ESP-IDF (VS Code), which also provides relevant example programs for reference.
