# BSP: ESP32-S3-LCD-EV-BOARD [](https://components.espressif.com/components/espressif/esp32_s3_lcd_ev_board) * [User Guide](https://docs.espressif.com/projects/espressif-esp-dev-kits/en/latest/esp32s3/esp32-s3-lcd-ev-board/user_guide.html)  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: | Board Name | Screen Size (inch) | Resolution | LCD Driver IC (Interface) | Touch Driver IC | Schematic | Support | | -------------------------- | ------------------ | ---------- | ------------------------- | --------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------ | ------- | | ESP32-S3-LCD_Ev_Board_SUB1 | 0.9 | 128 x 64 | SSD1315 (I2C) | * | [link](https://github.com/espressif/esp-dev-kits/blob/master/docs/_static/esp32-s3-lcd-ev-board/schematics/SCH_ESP32-S3-LCD_Ev_Board_SUB1_V1.0_20220617.pdf) | Not yet | | | 2.4 | 320 x 240 | ST7789V (SPI) | XTP2046 | | Not yet | | ESP32-S3-LCD_Ev_Board_SUB2 | 3.5 | 480 x 320 | ST7796S (8080) | GT911 | [link](https://github.com/espressif/esp-dev-kits/blob/master/docs/_static/esp32-s3-lcd-ev-board/schematics/SCH_ESP32-S3-LCD_Ev_Board_SUB2_V1.0_20220615.pdf) | Not yet | | | 3.95 | 480 x 480 | GC9503CV (RGB) | FT5x06 | | Yes | | ESP32-S3-LCD_Ev_Board_SUB3 | 4.3 | 800 x 480 | Unkonw (RGB) | GT1151 | [link](https://github.com/espressif/esp-dev-kits/blob/master/docs/_static/esp32-s3-lcd-ev-board/schematics/SCH_ESP32-S3-LCD_Ev_Board_SUB2_V1.0_20220615.pdf) | Yes | 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_LCD_RGB_BUFFER_NUMS`: Set number of frame buffers. Only when it is set to multiple can the anti-tearing function be turned on. * `BSP_LCD_RGB_REFRESH_MODE`: Select the refresh mode for RGB LCD. * `BSP_LCD_RGB_REFRESH_AUTO`: Refresh the LCD in the most common way. * `BSP_LCD_RGB_REFRESH_MANUALLY`:Refresh the LCD in a specific task. It can reduce the bandwidth of PSRAM usage. * `BSP_LCD_RGB_BOUNCE_BUFFER_MODE`: Enable bounce buffer mode can achieve higher PCLK frequency at the cost of higher CPU consumption. **And it's helpful when the screen drifts (Especially using Wi-Fi or OTA)**. It should be used with `ESP32S3_DATA_CACHE_LINE_64B`. * `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 multiple buffers. Need to set `BSP_LCD_RGB_BUFFER_NUMS` more than 1. * `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 direct mode.

# ChangeLog ## v1.0.3 - 2023-02-13 ### Features * Configurations: * Support to set number of frame buffers for RGB * Support to use bounce-buffer for RGB * Support to change the minimum delay time of LVGL task * Support to change the stack size of LVGL task * Support to enable anti-tearing function simply by using multiple buffers * RGB Anti-tearing: * Optimize direct mode * Use triple-buffer in full-refresh mode
