[wavic]

In the examples of the dot3k the instance of the main class is passed as an argument to the Menu:

my_invader = SpaceInvader() # creating an instance

menu = Menu({
        'Space Invader': my_invader,
        'Clock': Clock(),
        'Status': {
            'IP': IPAddress(),
            'CPU': GraphCPU(),
            'Temp': GraphTemp()
        },
        'Settings': {
            'Volume': Volume(),
            'Display': {
                'Contrast': Contrast(lcd),
                'Backlight': Backlight(backlight)
            }
        }
    },
    lcd,
    my_invader, # here it is passed as an argument.
