+### How to avoid I2C re-initialization when using ESP32_Display_Panel in Arduino IDE (e.g., when using Wire library)?
+
+If you need to use ESP32_Display_Panel's I2C bus functionality, such as `I2C IO_Expander` or `I2C Touch` drivers, while your project is already using the `Wire` library, errors may occur due to I2C bus re-initialization. To avoid this, initialize `Wire` before creating the `Board` object, then follow these steps to configure ESP32_Display_Panel to skip I2C initialization:
+
+1. By modifying the *esp_panel_board_custom_conf.h* configuration file (only applicable for [custom boards](#loading-of-custom-boards)):
+
+- For `I2C Touch` driver:
+
+    ```c
+    ...
+    #define ESP_PANEL_BOARD_LCD_BUS_SKIP_INIT_HOST    (1)     // 0/1
+    ...
+    ```
+
+- For `I2C IO_Expander` driver:
+
+    ```c
+    ...
+    #define ESP_PANEL_BOARD_EXPANDER_SKIP_INIT_HOST     (1)     // 0/1
+    ...
+    ```
+
+2. By using code (applicable for both [supported boards](#loading-of-supported-boards) and [custom boards](#loading-of-custom-boards)):
+
+    ```c
+    ...
+    esp_panel::board::Board *board = new esp_panel::board::Board();
+    board->init();
+    ...
+    /**
+     * Should be called after `board->init()` and before `board->begin()`
+     */
+    // For I2C Touch
+    static_cast<esp_panel::drivers::BusI2C *>(board->getTouch()->getBus())->configI2C_HostSkipInit();
+    // For I2C IO_Expander
+    board->getIO_Expander()->skipInitHost();
+    ...
+    board->begin();

+# Other FAQs
+
+## Can't find drivers for the same model of LCD/Touch device?
+
+For **LCD**, devices with the same interface type (SPI, QSPI, etc.) have similar or even identical driving methods. For example, ILI9341 and GC9A01 have almost identical driver code when using the SPI interface. Therefore, you can try using drivers for other devices with the same interface type.
+
+For **Touch**, drivers for some devices in the same series are compatible, such as CST816S, CST816D, and CST820 having compatible driver code. Therefore, you can check the technical manuals of devices in the same series to determine if there is compatibility (devices with the same I2C address are usually compatible).
+
+If the above methods cannot solve your problem, you can create a [Github Issue](https://github.com/esp-arduino-libs/ESP32_Display_Panel/issues) to request adding a driver.

+
+## 找不到相同型号的 LCD/Touch 设备驱动？
+
+对于 **LCD**，具有相同接口类型（SPI、QSPI 等）的设备的驱动方式是类似的，甚至是相同的,例如 ILI9341 和 GC9A01 在使用 SPI 接口时，驱动代码几乎相同。因此,您可以尝试使用其他相同接口类型的设备驱动。
+
+对于 **Touch**，部分相同系列设备的驱动是兼容的，如 CST816S 和 CST816D 以及 CST820 的驱动代码是兼容的。因此，您可以查阅相同系列设备的技术手册判断是否存在兼容性（如具有相同的 I2C 地址的设备通常是兼容的）。
+
+如果上述方法无法解决问题，您可以创建 [Github Issue](https://github.com/esp-arduino-libs/ESP32_Display_Panel/issues) 请求添加驱动。
