Run `idf.py menuconfig` to open a terminal UI where you can tune specific configuration for this example in the `Example Configuration` menu.
* `i80 LCD controller model`: Choose the LCD model to use by the example. If you choose `NT35510`, there will be another relevant configuration `NT35510 Data Width`, to choose the data line width for your NT35510 LCD module.
* `Allocate color data from PSRAM`: Select this option if you want to allocate the LVGL draw buffers from PSRAM.
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.
