I was having issues with this code:

using System;using GoBus;using Microsoft.SPOT;using Microsoft.SPOT.Hardware;using NetduinoGo;using System.Threading;using SecretLabs.NETMF.Hardware.NetduinoGo;namespace MFConsoleApplication1{    public class Program    {        //notice the static ShieldBase        static ShieldBase shieldBase = new ShieldBase(GoSockets.Socket5);        public static void Main()        {            var ledPort = new OutputPort(shieldBase.Pins.GPIO_PIN_D4, false);            while (true)            {                ledPort.Write(!ledPort.Read());                System.Threading.Thread.Sleep(250);            }        }    }}

It throws this:

An unhandled exception of type 'System.Exception' occurred in GoBusSerialTransport.dll

but this code works fine:

using System;using GoBus;using Microsoft.SPOT;using Microsoft.SPOT.Hardware;using NetduinoGo;using System.Threading;using SecretLabs.NETMF.Hardware.NetduinoGo;namespace MFConsoleApplication1{    public class Program    {        public static void Main()        {            ShieldBase shieldBase = new ShieldBase(GoSockets.Socket5);            var ledPort = new Microsoft.SPOT.Hardware.OutputPort(shieldBase.Pins.GPIO_PIN_D4, false);            while (true)            {                ledPort.Write(!ledPort.Read());                System.Threading.Thread.Sleep(250);            }        }    }}

Why can't I have a static instance of a go!bus module? 

 

A similar exception happened when I tried to use the button (making it static vs not static) except the exception occurred in a different dll (whichever one contains the button)

Now Im having another issue. here is my new code:

using System;using GoBus;using Microsoft.SPOT;using Microsoft.SPOT.Hardware;using NetduinoGo;using System.Threading;using SecretLabs.NETMF.Hardware.NetduinoGo;namespace MFConsoleApplication1{	public class Program	{		public static void Main()		{			var shieldBase = new ShieldBase(GoSockets.Socket5);			var pot = new Potentiometer(GoSockets.Socket1);			var blue = new OutputPort(shieldBase.Pins.GPIO_PIN_A3, false);			var green = new OutputPort(shieldBase.Pins.GPIO_PIN_A4, false);			var red = new OutputPort(shieldBase.Pins.GPIO_PIN_A5, false);			int c = 0;			while (true)			{				blue.Write(false);				green.Write(false);				red.Write(false);				if (c == 0) red.Write(true);				else if (c == 1) green.Write(true);				else if (c == 2)				{					blue.Write(true);					c = 0;				}				c++;				Thread.Sleep((int)(1000 * pot.GetValue()));			}		}	}}

Now I receive this error when I create the potentiometer:

A first chance exception of type 'System.ArgumentException' occurred in NetduinoGo.Potentiometer.dll

What is going on here!

[adam8797]

Well, I figured out why the potentiometer didn't work, there is somthing wrong the port 1 the board. Moved to port two and no issue.

 

Any ideas, or do you think its faulty?

I've never used the Go! but it sounds as if the port is broken. This can happen if you draw to much current in trying to drive too big a load. It has happened to me a couple of times and so I simply avoid using the corresponding ports anymore. Does the port work when used as an input?

[eplaksienko]

Try GO ports 1 and 4, it works either 1-4 or 5-8 right now, Chris can correct me If I am wrong

[adam8797]

Well, about the bad ports, I just tried this code

...public static void Main(){    var b = new Button(GoSockets.Socket2);    var l = new RgbLed(GoSockets.Socket1);    l.SetColor(255, 0, 0);    l.SetBrightness(1);    b.ButtonPressed += (sender, pressed) => l.SetColor(0, 255, 0);    while (true)    {        Debug.Print("done");    }}

And the button works, so there goes the idea that port one is bad (although when the go! boots up, the led on 1 and 2 only flash, they don't stay solid like the rest)

 

 

but my previous code still won't work. Im at a loss here.

while (true){    Debug.Print("done");}

 

wow that looks mean

 

add s leep 1 at least

Yeah, I just wanted to make sure it didn't freeze!
