# ESP LCD NV3023
Modified from [here]().
Implementation of the NV3023 LCD controller with esp_lcd component.
| LCD controller | Communication interface | Component name | Link to datasheet |
| :------------: | :---------------------: | :------------: | :---------------: |
| NV3023 | SPI | esp_lcd_nv3023 | [Specification](https://admin.osptek.com/uploads/NV_3023_A_Datasheet_20191218_73d75e6d84.pdf) |
### Supported Display
- ​ 0.85' TFT 128 x128
-
## Add to project
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).
```
