Having this code
using System;
using System.Threading;
using Microsoft.SPOT;
using SecretLabs.NETMF.Hardware.NetduinoGo;
namespace GoConsole
{
public class Program
{
public static void Main()
{
NetduinoGo.Button btn = new NetduinoGo.Button(GoSockets.Socket1);
btn.ButtonPressed += new NetduinoGo.Button.ButtonEventHandler(btn_ButtonPressed);
btn.ButtonReleased += new NetduinoGo.Button.ButtonEventHandler(btn_ButtonReleased);
Thread.Sleep(Timeout.Infinite);
}
static void btn_ButtonReleased(object sender, bool buttonState)
{
Debug.Print(DateTime.Now.ToString("ss.fff") + " btn_ButtonReleased state: " + buttonState);
}
static void btn_ButtonPressed(object sender, bool buttonState)
{
Debug.Print(DateTime.Now.ToString("ss.fff") + " btn_ButtonPressed state: " + buttonState);
}
}
}
If I press the button and hold it down for a short time I get this output:
33.411 btn_ButtonPressed state: True 35.495 btn_ButtonReleased state: False
Just what I expected.
If I press it and immediately release it, the output often look like this:
41.911 btn_ButtonReleased state: False 41.912 btn_ButtonPressed state: True 42.001 btn_ButtonReleased state: False
or this
13.002 btn_ButtonReleased state: False 13.003 btn_ButtonReleased state: False 13.004 btn_ButtonPressed state: True 13.116 btn_ButtonReleased state: False
Occasionally this pattern also happens if I press and hold the button down.
47.208 btn_ButtonReleased state: False 47.209 btn_ButtonPressed state: True 52.804 btn_ButtonReleased state: False
My point is, sometimes I get one or two release events before the press event even though I haven't released it, is that digital bounce and as is and should I just handle it in code then?
Thank you
Kristoffer
