- `hor_res` horizontal resolution of the display in pixels.
- `ver_res` vertical resolution of the display in pixels.
- `flush_cb` a callback function to copy a buffer's content to a specific area of the display.
`lv_disp_flush_ready(&disp_drv)` needs to be called when flushing is ready.
- `lv_disp_flush_ready(&disp_drv)` needs to be called when flushing is ready.
LVGL might render the screen in multiple chunks and therefore call `flush_cb` multiple times. To see if the current one is the last chunk of rendering use `lv_disp_flush_is_last(&disp_drv)`.
