[esp_lcd](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/peripherals/lcd.html) provides several panel drivers out-of box, e.g. ST7789, SSD1306, NT35510. However, there're a lot of other panels on the market, it's beyond `esp_lcd` component's responsibility to include them all.
`esp_lcd` allows user to add their own panel drivers in the project scope (i.e. panel driver can live outside of esp-idf), so that the upper layer code like LVGL porting code can be reused without any modifications, as long as user-implemented panel driver follows the interface defined in the `esp_lcd` component.
This example shows how to use GC9A01 or ILI9341 display driver from Component manager in esp-idf project. These components are using API provided by `esp_lcd` component. This example will draw a fancy dash board with the LVGL library. For more information about porting the LVGL library, you can also refer to [another lvgl porting example](../i80_controller/README.md).
## Touch controller STMPE610
In this example you can enable touch controller STMPE610 connected via SPI. The SPI connection is shared with LCD screen.
The GPIO number used by this example can be changed in [lvgl_example_main.c](main/spi_lcd_touch_example_main.c).
Especially, please pay attention to the level used to turn on the LCD backlight, some LCD module needs a low level to turn it on, while others take a high level. You can change the backlight level macro `EXAMPLE_LCD_BK_LIGHT_ON_LEVEL` in [lvgl_example_main.c](main/spi_lcd_touch_example_main.c).
Run `idf.py -p PORT build flash monitor` to build, flash and monitor the project. A fancy animation will show up on the LCD as expected.
The first time you run `idf.py` for the example will cost extra time as the build system needs to address the component dependencies and downloads the missing components from registry into `managed_components` folder.
(To exit the serial monitor, type ``Ctrl-]``.)
See the [Getting Started Guide](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/index.html) for full steps to configure and use ESP-IDF to build projects.
