Noob InterruptPort Question

InterruptPort Button

Hi Paul,

Two things...
1. Did you mean to use InterruptEdgeLevelHigh (interrupt repeats infinitely when signal is high) in your InterruptPort constructor? Or InterruptEdgeHigh (low-to-high signal transition)? The latter is supported by the core STM32 BSP; the former may not be.
2. If changing that doesn't fix the issue for you, try moving the object creation to Main(). In NETMF, some of the class-level variables may be instantiated in an order which is a bit different from the desktop .NET Framework.

Does that get you up and running?

private static InterruptPort button = new InterruptPort(Pins.ONBOARD_SW1, true, Port.ResistorMode.Disabled, Port.InterruptMode.InterruptEdgeLevelHigh);

private static void Main(){        
   // Attach button listener 
   button.OnInterrupt +=new NativeEventHandler((uint port,uint state, DateTime time) =>{ Debug.Print("Hola")});
}
Simply subscribing to the event throws an ArgumentException:
StackTrace "Microsoft.SPOT.Hardware.InterruptPort::EnableInterrupt\r\nMicrosoft.SPOT.Hardware.NativeEventDispatcher::add_OnInterrupt\r\nNetduinoApplication1.Program::Main\r\n" string
 
I started my netduino on 4.2.2 but I just upgraded to 4.3.1 with the same results.  Any ideas?
 
Paul

#1 did the trick, thanks Chris.  Looking forward to doing some cool stuff here!
