Pins.ONBOARD_BTN is wired to the wrong pin

[bryancostanich]

The following code should light the onboard LED when the button is pressed because we're creating an InputPort that listens to the ONBOARD_BTN pin, however, it actually resets the board:

using System;
using Microsoft.SPOT;
using Microsoft.SPOT.Hardware;
using SecretLabs.NETMF.Hardware.Netduino;

namespace OnboardButtonAndLed
{
	public class Program
	{
		// An output port allows you to write (send a signal) to a pin
		static OutputPort _led = new OutputPort(Pins.ONBOARD_LED, false);
		// An input port reads the signal from a pin
		static InputPort _button = new InputPort(Pins.ONBOARD_BTN, false, Port.ResistorMode.Disabled);

		static bool _buttonPressed = false;

		public static void Main()
		{
			// turn the LED off initially
			_led.Write(false);

			// run forever
			while (true)
			{
				// set the onboard LED output to be the input of the button
				_led.Write(_button.Read());
			}

		}
	}
}

however, if I create the onboard button this way, it works:

static InputPort _button = new InputPort((Cpu.Pin)0x15, false, Port.ResistorMode.Disabled);

Evidently, this was fixed in an earlier firmware version, but regressed: http://forums.netduino.com/index.php?/topic/11844-newbie-onboard-button-in-a-program/

Fixed in 4.3.2.4Pre2
