Then display driver and input driver needs to be registered.
Then event loop, display driver and input driver needs to be registered.
Refer to [Porting the library](https://docs.lvgl.io/8.0/porting/index.html) for more information.
Here is an example of registering SDL drivers on Micropython unix port:
```python
import SDL
SDL.init()
# Create an event loop and Register SDL display/mouse/keyboard drivers.
from lv_utils import event_loop
# Register SDL display driver.
WIDTH = 480
HEIGHT = 320
draw_buf = lv.disp_draw_buf_t()
buf1_1 = bytearray(480*10)
draw_buf.init(buf1_1, None, len(buf1_1)//4)
disp_drv = lv.disp_drv_t()
disp_drv.init()
disp_drv.draw_buf = draw_buf
disp_drv.flush_cb = SDL.monitor_flush
disp_drv.hor_res = 480
disp_drv.ver_res = 320
disp_drv.register()
# Regsiter SDL mouse driver
indev_drv = lv.indev_drv_t()
indev_drv.init()
indev_drv.type = lv.INDEV_TYPE.POINTER
indev_drv.read_cb = SDL.mouse_read
indev_drv.register()
event_loop = event_loop()
disp_drv = lv.sdl_window_create(WIDTH, HEIGHT)
mouse = lv.sdl_mouse_create()
keyboard = lv.sdl_keyboard_create()
keyboard.set_group(self.group)
```
Here is an alternative example, for registering ILI9341 drivers on Micropython ESP32 port:
