Hi Guys,

Its worth mentioning that since the switch was initially meant to be a "Restart" switch, its default state is "on". In other words, the thing will read "true" unless you push it. This is why he netduino guy had to invert the bool for it to act like you would expect.

I was scratching my head for a bit there too.

Hi, smjjasdaf. The ONBOARD_SW1 is physically tied high (3.3V), and is driven to ground (0V) when you press it. It might be simpler for users if we just flipped the logic via firmware, to make it read TRUE when pressed. That wouldn't be hard to do. Thoughts?
