Hi All,

I am trying to handle the button pressure.

I want to log the time when i press the button on Netduino plus but C# reports the following output message after i launch the app.


#### Exception System.OutOfMemoryException - CLR_E_OUT_OF_MEMORY (1) ####
#### Message:
#### System.Delegate::Combine [IP: 0000] ####
#### Microsoft.SPOT.Hardware.NativeEventDispatcher::add_OnInterrupt [IP: 0014] ####
#### NetduinoPlusApplication1.Program::Main [IP: 004a] ####
Uncaught exception

the code of my application is the following:

using System;
using System.Net;
using System.IO;
using System.Net.Sockets;
using System.Threading;
using Microsoft.SPOT;
using Microsoft.SPOT.Hardware;
using SecretLabs.NETMF.Hardware;
using SecretLabs.NETMF.Hardware.NetduinoPlus;

namespace NetduinoPlusApplication1
{
    public class Program
    {
     
        public static void Main()
        {
            DirectoryInfo usd = new DirectoryInfo(@"\SD\");
            InterruptPort button = new InterruptPort(Pins.GPIO_PIN_D8, true, Port.ResistorMode.PullUp, Port.InterruptMode.InterruptEdgeLevelLow);

            if (usd.Exists)
            { 
                usd.Create();
                usd.CreateSubdirectory(@"\SD\Prova\");
                FileStream fstr = new FileStream(@"\SD\Prova\prova.dat", FileMode.Create);
                fstr.Flush();
                fstr.Close();
               while (true)
               {
                   button.OnInterrupt += new NativeEventHandler(button_OnInterrupt);
                   button.ClearInterrupt();
              } //close while
            }//close if
        } //close Main

        static void button_OnInterrupt(uint port, uint state, DateTime time)
        {
            OutputPort led = new OutputPort(Pins.ONBOARD_LED, false);
            int ltime = 50000; 
            StreamWriter fstr1 = new StreamWriter(@"\SD\Prova\prova.dat", true); 
            if (state == 0) {
                fstr1.WriteLine(System.DateTime.Now.ToString());
                fstr1.Flush();
                fstr1.Close();
                led.Write(true);
                Thread.Sleep(ltime);
                led.Write(false);
                //Thread.Sleep(ltime);
            };
        }

    }
}

Could someone explain me something about the exception not handled and what generate the exception?

Thank you!

Rgds, Daniele.

Everything you need to know was right there in the first error:

#### System.Delegate::Combine [IP: 0000] ####
#### Microsoft.SPOT.Hardware.NativeEventDispatcher::add_OnInterrupt [IP: 0014] ####
#### NetduinoPlusApplication1.Program::Main [IP: 004a] ####

This is saying in your application NetduinoPlusApplication1 has an object Program with a function Main which has some instruction that is, under the hood, calling NativeEventDispatcher object's add_OnInterrupt method. That is in turn calling Delegate object's Combine method. From experience, I know when you do <event> += <handler> this uses Combine to join your new handler into the pool of handlers that want to be called when this event is fired.

That gives us all the information we need to find the problem. Looking at your code, there's only one place you're doing a handler assignment to an event:

while (true)
{
    button.OnInterrupt += new NativeEventHandler(button_OnInterrupt);
    button.ClearInterrupt();
}

We see this is being done in an infinite loop. Basically you're attaching a copy of your event handler again and again and again until the Netduino runs out of memory space.

You can read up on Event Based Programming but in short to fix your issue, just move your event wire-up above the while loop (which I assume you have just to keep the main thread alive; in which case you should consider adding a sleep call to put the main thread to sleep when it's not needed.)

Hope this helps!

Hi Erik, First of all i want to say thank you for your help. Then i have a question: How can i do a infinite-loop using Thread.sleep method? It request a finite-time has parameter. thank you very much. Best Regards, Daniele.

It depends on your need. If you want to wake up from time to time before going back to sleep:

public static void Main()
{
    //Do your event wireup and any other thread work

    //Then, last thing:
    while(true)
    {
        //Do any periodic work you need executed on the main thread for some reason
        Thread.Sleep(10000); // 10 seconds or whatever
    }
}

If you don't ever need the main thread to wake up to do something then you don't need a loop at all and you can put the thread to sleep forever. Your event threads will continue to process; this is just the main thread which you need to keep active so the whole program doesn't terminate.

public static void Main()
{
    //Do your event wireup and any other thread work

    //Then, last thing:
    Thread.Sleep(Timeout.Infinite);
}
