Displayotron-3000 - toggle backlight on/off with joystick

Support
1

Hi,

I’m wondering if there is a way to check the backlight status on a Displayotron 3000 (e.g., if the backlight is currently on, or off), so that when I push the joystick button the backlight is either toggled on or off.

I tried to do the following, but it doesn’t work.

@nav.on(nav.BUTTON)
def handle_button(pin):
    if backlight.off():
         backlight.rgb(50, 255, 50)
    else:
        backlight.off()

The only way I managed to accomplish this is if I introduce a variable called “status” and change to either True or False. It works, but it doesn’t seem to be an elegant solution.

@nav.on(nav.BUTTON)
def handle_button(pin):
    global status
    if status:
        backlight.off()
        status=False
    else:
        backlight.rgb(50, 255, 50)
        status=True
