Hi,

 

is it possible to wait for a signal for example on Pin 9 for a high or low signal and start an interreupt or event on this signal?

Hi Kalio,

 

An InterruptPort can be configured to call an eventhandler in response to an EdgeLow, EdgeHigh, EdgeBoth, EdgeLevelHigh, or EdgeLevelLow transition(s) on a pin.

 

You may need to add "debounce" logic to your code.

public class Program
{
   static OutputPort interuptled = new OutputPort(Pins.ONBOARD_LED, false);

   public static void Main()
   {
      InterruptPort button = new InterruptPort(Pins.ONBOARD_SW1, false, 
                                 Port.ResistorMode.Disabled, Port.InterruptMode.InterruptEdgeHigh);

         button.OnInterrupt += new NativeEventHandler(button_OnInterrupt);

         Thread.Sleep(Timeout.Infinite);  
      }



      static void button_OnInterrupt(uint data1, uint data2, DateTime time)
      {
         interuptled.Write(!interuptled.Read());
      }
   }
}

Ok, thanks that helps me alot, but is there a way to activate the interrupt or similar just when i need it? For example if i got 3 Modes, and i am in Mode 2, and it start execute when i got my interrupt on Pin.Any..., but if i am in Mode 3, then the interrupt should be blocked and only available for Mode 2?

 

Thanks in advance

Hi Zoro,

 

If you just want to activate/deactivate the interrupt in specific state(s) then have a look at 

 

         button.DisableInterrupt();

 

 

         button.EnableInterrupt();

 

 

You could call these from your state machine logic

How about something like:

 

public class Program

{

    public enum Modes

    {

         ModeUnknown,

         Mode1,

         Mode2,

         Mode3

    }

 

 

       static OutputPort interuptled = new OutputPort(Pins.ONBOARD_LED, false);

 

       static Modes currentMode = Modes.ModeUnknown;

 

       public static void Main()

       {

 

            InterruptPort button = new InterruptPort(Pins.ONBOARD_SW1, false, 

                                     Port.ResistorMode.Disabled, Port.InterruptMode.InterruptEdgeHigh);

 

            button.OnInterrupt += new NativeEventHandler(button_OnInterrupt);

 

            currentMode = Modes.Mode2;

 

            Thread.Sleep(Timeout.Infinite);  

        }

 

 

 

        static void button_OnInterrupt(uint data1, uint data2, DateTime time)

        {

            switch (currentMode)

            {

                case Modes.Mode1:

                    interuptled.Write(!interuptled.Read());

                    break;

 

                case Modes.Mode2:

                    // DO MODE 2 WORK...

                    break;

                

                case Modes.Mode3:

                    // DO MODE 3 WORK...

                    break;

                

                default:

                    // UNKNOWN MODE?  RAISE ERROR?

                    break;

            }

        }

    }
