OK, finally found the issue.

Despite that intellisense wants me to populate "new InterruptPort(Cpu.Pin" it appears the Cpu.Pin types do not work the same as the Pins type.

So this works;

button = new InterruptPort(Pins.GPIO_PIN_D1, false, Port.ResistorMode.Disabled, Port.InterruptMode.InterruptEdgeLow);

but this does not;

button = new InterruptPort(Cpu.Pin.GPIO_Pin1, false, Port.ResistorMode.Disabled, Port.InterruptMode.InterruptEdgeLow);

OK, I found the issue with the exception.

This does not work;

new InterruptPort(Cpu.Pin.GPIO_Pin0, false, Port.ResistorMode.PullUp, Port.InterruptMode.InterruptEdgeLevelHigh);

But this does;

new InterruptPort(Cpu.Pin.GPIO_Pin0, false, Port.ResistorMode.PullUp, Port.InterruptMode.InterruptEdgeHigh);

Notice the different Port.InterruptMode. Not sure what the issue with the InterruptEdgeLevelHigh is.

But what I cannot understand is why now the Interrrupt seems to create ok but it still will not trigger. Despite the fact that if I manually read the button I can see the state change.

I have the exact same issue with the NetDuino3 Ethernet. Did we get anywhere with this?

Sorry Nevyn, replacing my code with exactly what you suggested still gives the same issue. Even tried a number of little tweaks and changes to your code and still the same result. 

It seems like so many of the libraries and methods for ND3 have changed so much that it is really hard to get back to a working project. And there are very few examples for all these new libraries.

Hi All,

Having a strange issue again with the ND3.

This code worked fine on my ND+ but will not work on my ND3

        public static InterruptPort button = new InterruptPort(Pins.GPIO_PIN_D0, false, Port.ResistorMode.PullDown, Port.InterruptMode.InterruptEdgeLevelHigh);


        public static void Main()
        {
            try
            {
                button.OnInterrupt += new NativeEventHandler(button_OnInterrupt);
            }
            catch (Exception EX)
            {
                Debug.Print(EX.Message.ToString());
            }
..........

public static void button_OnInterrupt(uint data1, uint data2, DateTime time)
        {
..........

When I debug it throws an argument exception for "button.OnInterrupt += new NativeEventHandler(button_OnInterrupt);" every single time. Have tried hundreds of little changes and tweaks and I could swear it actually worked a few times but cannot figure out what I am doing wrong.

They do.

Hey all,

Wondering if anyone has any ideas about this. I have two different projects, both created for the Netduino3 Ethernet.

One is a simple blinking light for testing hardware and I can deploy and run it fine.

The other is the actual application I am developing and it worked the first couple times after I created it. (copied source code from an ND+ project). But now for some reason everytime I try to deploy I get the following message.

"Error 1 An error has occurred: please check your hardware. "
