## Add to project

Packages from this repository are uploaded to [Espressif's component service](https://components.espressif.com/).
You can add them to your project via `idf.py add-dependancy`, e.g.

```
idf.py add-dependency esp_lcd_ili9341==1.0.0
```

Alternatively, you can create `idf_component.yml`. More is in [Espressif's documentation](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/tools/idf-component-manager.html).

**NOTE:** if your display is not initilized properly, try using config **ALTERNATIVE_DRIVER**
