display:

    model: CUSTOM
    height: 320

    # lambda: |-
    #   // Draw a circle in the middle of the display
    #   it.filled_circle(it.get_width() / 2, it.get_height() / 2, 20);

lvgl:
  displays:
    - my_display
  pages:
    - id: main_page
      widgets:
        - label:
            align: CENTER
            text: 'Hello World!'

This will display a white screen with black hello world in the center.
If you uncomment the lamda code, comment out the lvgl code. Cannot use both at the same time, compiler complains.
