# ESP LCD JD9365

[![Component Registry](https://components.espressif.com/components/espressif/esp_lcd_jd9365/badge.svg)](https://components.espressif.com/components/espressif/esp_lcd_jd9365)

Implementation of the JD9365 LCD controller with esp_lcd component.

| LCD controller | Communication interface | Component name |                                   Link to datasheet                                   |

**Note**: MIPI-DSI interface only supports ESP-IDF v5.3 and above versions.

## 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 "espressif/esp_lcd_jd9365"
```

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).

## Example use

```c
/**
 * Uncomment these line if use custom initialization commands.
 * The array should be declared as static const and positioned outside the function.
 */
// static const jd9365_lcd_init_cmd_t lcd_init_cmds[] = {
//  {cmd, { data }, data_size, delay_ms}
// {0xE0, (uint8_t []){0x00}, 1, 0},
// {0xE1, (uint8_t []){0x93}, 1, 0},
// {0xE2, (uint8_t []){0x65}, 1, 0},
// {0xE3, (uint8_t []){0xF8}, 1, 0},
//     ...
