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:

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_REFRESH_MANUALLY`: Refresh the LCD within a dedicated task. This can help manage PSRAM bandwidth.
    * `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, especially in scenarios involving Wi-Fi usage or writing to Flash memory. For more detailed information, refer to the documentation [here](https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/api-reference/peripherals/lcd.html#bounce-buffer-with-single-psram-frame-buffer).** This feature should be used in conjunction with `ESP32S3_DATA_CACHE_LINE_64B` configuration.
* `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 when enable `BSP_DISPLAY_LVGL_ROTATION_NONE`.
        * `BSP_DISPLAY_LVGL_DIRECT_MODE`: Use LVGL's direct mode.
    * `BSP_DISPLAY_LVGL_ROTATION`: Rotate the screen clockwise. This requires setting `BSP_LCD_RGB_BUFFER_NUMS` to `3`. **The rotation is software-based and will substantially reduce FPS if enabled.**
        * `BSP_DISPLAY_LVGL_ROTATION_NONE`: No rotation.
        * `BSP_DISPLAY_LVGL_ROTATION_90`: 90-degree rotation.
        * `BSP_DISPLAY_LVGL_ROTATION_180`: 180-degree rotation.
        * `BSP_DISPLAY_LVGL_ROTATION_270`: 270-degree rotation.

                                        # Display LVGL Demos

This example shows LVGL internal demos with RGB LCD.

### Configurations

To improve display performance (FPS), please set the following configurations:

* System:
    * `ESP_DEFAULT_CPU_FREQ_MHZ_240`
    * `FREERTOS_HZ` = 1000
    * `COMPILER_OPTIMIZATION_PERF`
* Flash:
    * `ESPTOOLPY_FLASHMODE_QIO`
    * `ESPTOOLPY_FLASHFREQ_120M`
* PSRAM:
    * `SPIRAM_MODE_OCT`
    * `SPIRAM_SPEED_120M` (See [here](https://github.com/espressif/esp-dev-kits/tree/master/esp32-s3-lcd-ev-board#psram-120m-ddr) to enbale this feature of ESP-IDF)
    * `SPIRAM_FETCH_INSTRUCTIONS`
    * `SPIRAM_RODATA`
* Cache:
    * `ESP32S3_DATA_CACHE_LINE_64B` (It can be enabled only when using bounce buffer or PSRAM with Octal 120M. Otherwise it will cause screen drift.)
* LVGL
    * `LV_MEM_CUSTOM`
    * `LV_MEMCPY_MEMSET_STD`
    * `LV_ATTRIBUTE_FAST_MEM_USE_IRAM`
