You can just do
Object.keys(global)I think. The pins themselves aren't listed, but you could trygetPinMode(0)/1/2/...all the way up until you get an exception (since getPinMode won't change pin state)But again, if you just try what you did above with all pins you could damage your board (and will definitely break USB), as you have no idea what they're connected to when you set them to something.
