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 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:

# Display LVGL Demos

This example shows LVGL internal demos with RGB LCD.

### Configurations

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

* `BSP_LCD_SUB_BOARD`: Choose a LCD sub-board according to hardware
* `BSP_DISPLAY_LVGL_BUF_CAPS`: Choose the memory type of LVGL buffer. Internal memory is more fast.
* `BSP_DISPLAY_LVGL_BUF_HEIGHT`: Set the height of LVGL buffer, and its width is equal to LCD's width.
* `BSP_DISPLAY_LVGL_AVOID_TEAR`: Avoid tearing effect by using double buffers. Need to enable `BSP_LCD_RGB_DOUBLE_BUFFER` and `BSP_LCD_RGB_REFRESH_TASK_ENABLE` first.

### Hardware Required

ESP32-S3-LCD-EV-BOARD with 800x480 or 480x480 LCD sub-board.
