ESP32-S3-LCD-EV-Board is a development board for evaluating and verifying ESP32-S3 screen interactive applications. It has the functions of touch screen interaction and voice interaction. The development board has the following characteristics:

* Onboard ESP32-S3-WROOM-1 module, with built-in 16 MB Flash + 8/16 MB PSRAM
* Onboard audio codec + audio amplifier
* Onboard dual microphone pickup
* USB type-C interface download and debugging
* It can be used with different screen sub boards, and supports `RGB`, `8080`, `SPI`, `I2C` interface screens, as below:

Here are some useful configurations in menuconfig that can be customed by user:

* `BSP_LCD_RGB_BUFFER_NUMS`: Configure the number of frame buffers. The anti-tearing function can be activated only when set to a value greater than one.
* `BSP_LCD_RGB_REFRESH_MODE`: Choose the refresh mode for the RGB LCD.
    * `BSP_LCD_RGB_REFRESH_AUTO`: Use the most common method to refresh the LCD.
    * `BSP_LCD_RGB_BOUNCE_BUFFER_MODE`: Enabling bounce buffer mode can lead to a higher PCLK frequency at the expense of increased CPU consumption. **This mode is particularly useful when dealing with [screen drift](https://docs.espressif.com/projects/esp-faq/en/latest/software-framework/peripherals/lcd.html#why-do-i-get-drift-overall-drift-of-the-display-when-esp32-s3-is-driving-an-rgb-lcd-screen), especially in scenarios involving Wi-Fi usage or writing to Flash memory.** This feature should be used in conjunction with `ESP32S3_DATA_CACHE_LINE_64B` configuration. For more detailed information, refer to the [documentation](https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/api-reference/peripherals/lcd.html#bounce-buffer-with-single-psram-frame-buffer).
* `BSP_DISPLAY_LVGL_BUF_CAPS`: Select the memory type for the LVGL buffer. Internal memory offers better performance.
* `BSP_DISPLAY_LVGL_BUF_HEIGHT`: Set the height of the LVGL buffer, with its width aligning with the LCD's width. The default value is 100, decreasing it can lower memory consumption.
* `BSP_DISPLAY_LVGL_AVOID_TEAR`: Avoid tearing effect by using multiple buffers. This requires setting `BSP_LCD_RGB_BUFFER_NUMS` to a value greater than 1.
    * `BSP_DISPLAY_LVGL_MODE`:
        * `BSP_DISPLAY_LVGL_FULL_REFRESH`: Use LVGL full-refresh mode. Set `BSP_LCD_RGB_BUFFER_NUMS` to `3` will get higher FPS`.
        * `BSP_DISPLAY_LVGL_DIRECT_MODE`: Use LVGL's direct mode.

Based on the above configurations, there are three different anti-tearing modes can be used:

* RGB double-buffer + LVGL full-refresh mode:
    * Set `BSP_LCD_RGB_BUFFER_NUMS` to `2`
    * Enable `BSP_DISPLAY_LVGL_AVOID_TEAR` and `BSP_DISPLAY_LVGL_FULL_REFRESH`
* RGB double-buffer + LVGL direct-mode:
    * Set `BSP_LCD_RGB_BUFFER_NUMS` to `2`
    * Enable `BSP_DISPLAY_LVGL_AVOID_TEAR` and `BSP_DISPLAY_LVGL_DIRECT_MODE`
* RGB triple-buffer + LVGL full-refresh mode:
    * Set `BSP_LCD_RGB_BUFFER_NUMS` to `3`
    * Enable `BSP_DISPLAY_LVGL_AVOID_TEAR` and `BSP_DISPLAY_LVGL_FULL_REFRESH`
