Netduino Project 2: Morsey

As discussed in my last post, I've created a small test app called Morsey to practice my LED lighting skills on the Netduino.

The functionality is simple: the application takes a constant English string and turns it into a string of dashes and dots, signaled by the LED. The signaling is started/stopped by clicking the on board button.

The code:
There are 3 code files:

1. The main program file, that runs the main thread and the Morse thread, as well as the button event.
   

   static void button_OnInterrupt(uint data1, uint data2, DateTime time)
   {
    bool isButtonDown = (data2 != 0);
    if (isButtonDown)
    {
     displayMessage = !displayMessage;
    }
    
    if (displayMessage)
    {
     if(morseThread.ThreadState == ThreadState.Unstarted)
      morseThread.Start();
     else
      morseThread.Resume();
    }
    else 
    {
     morseThread.Suspend();
     led.Off(); 
    }
   }
   

2. The MorseCharacters class. I copied the 2 Morse arrays from Scott Hanselman's great Netduino post (sorry Scott, just lazy and it's faster to C&P than to type all those dashes and dots :)).
3. The LED class - the same one I used in the TrafficLight project, with the addition of a single function:
   

   public void WriteMorse(String message) 
   {
    MorseCharacters converter = new MorseCharacters();
    String morseMessage = converter.ConvertMessageToMorse(message);
    if (morseMessage != String.Empty)
    {
     foreach (char c in morseMessage)
     {
      switch (c)
      {
       case '.':
        Dot();
        break;
       case '-':
        Dash();
        break;
       case ' ':
        //delay for twice the character gap between words
        Thread.Sleep(delay * 2); 
        break;
       default:    //handle errors here
        break;
      }
     }
    }
   }
