# LVGL porting example (based on i80 interfaced LCD controller)

LVGL is an open-source graphics library for creating modern GUIs. It has plenty of built-in graphical elements with low memory footprint, which is friendly for embedded GUI applications.

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.

This example supports touch screen connected via I2C. You can enable it by running `idf.py menuconfig` and navigating to `Example Configuration -> Enable LCD touch`. When touch is enabled, there will be a new button in the GUI that can restart the animation.

## Image Resource
|
||||
|
||||
This example supports two ways of reading images
|
||||
|
||||
* from the [SPIFFS file system](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/storage/spiffs.html). This is the suggested way we use in the example. It may take a little bit longer to load the image because of the bottleneck of the SPI flash read speed, but it will save the binary size.
|
||||
* from the embedded binary (i.e., pre-decode the image into an array and pack it together with the application firmware). By this way, you can get faster image loading speed at the cost of bloating your application binary. What's worse, if you enabled the [XIP from PSRAM](https://github.com/espressif/esp-idf/tree/master/examples/system/xip_from_psram) feature, it will increase the PSRAM usage as well.

@ -110,4 +120,4 @@ These touch controllers are supported:
|
||||
|
||||
This is because of the limited PSRAM bandwidth, compared to the internal SRAM. You can either decrease the PCLK clock `EXAMPLE_LCD_PIXEL_CLOCK_HZ` in [i80_controller_example_main.c](main/i80_controller_example_main.c) or increase the PSRAM working frequency `SPIRAM_SPEED` from the KConfig (e.g. **ESP32S3-Specific** -> **Set RAM clock speed**) or decrease the FPS in LVGL configuration. For illustration, this example has set the refresh period to 100ms in the default sdkconfig file.
