# ESP LCD ST7796
[![Component Registry](https://components.espressif.com/components/espressif/esp_lcd_st7796/badge.svg)](https://components.espressif.com/components/espressif/esp_lcd_st7796)
Implementation of the ST7796 LCD controller with esp_lcd component.
| LCD controller | Communication interface | Component name | Link to datasheet |
| :------------: | :---------------------: | :------------: | :---------------: |
| ST7796 | SPI/I80/MIPI-DSI | esp_lcd_st7796 | [Specification](https://www.displayfuture.com/Display/datasheet/controller/ST7796s.pdf) |
## 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-dependency`, e.g.
```bash
compote manifest add-dependency espressif/esp_lcd_st7796==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).
