 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
