# ESP LCD QSPI_AMOLED

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

Implementation of the QSPI_AMOLED LCD controller with [esp_lcd](https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/api-reference/peripherals/lcd.html) component.

## 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_qspi_amoled"
```

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).

## Notes

* When utilizing `esp_panel_lcd_draw_bitmap()` to refresh the screen, ensure that `x_start`, `y_start`, `x_end` and `y_end` are divisible by `2`. This is a requirement of SH8610. For LVGL, register the following function into `rounder_cb` of `lv_disp_drv_t` to round the coordinates.

```c
void lvgl_port_rounder_callback(struct _lv_disp_drv_t * disp_drv, lv_area_t * area)
{
    uint16_t x1 = area->x1;
    uint16_t x2 = area->x2;
    uint16_t y1 = area->y1;
    uint16_t y2 = area->y2;

// round the start of area down to the nearest even number
    area->x1 = (x1 >> 1) << 1;
    area->y1 = (y1 >> 1) << 1;

// round the end of area up to the nearest odd number
    area->x2 = ((x2 >> 1) << 1) + 1;
    area->y2 = ((y2 >> 1) << 1) + 1;
}
```
