   When I attempt to compile my project I get the following lines in the output and for probably these unknown reasons to me, SerialUSB.println("foo"); as the first line in setup never executes. Are there any traces that go deeper so I can see what is going on?

   Is there a reason that SerialUSB.println("foo"); doesn't work in setup? I tried it on the BareMinimum sketch.

   It's because the setup() routine does not wait for the serialusb to get connected before it finishes.

   Try this
   

   void setup()
   {
    pinMode(13, OUTPUT);
   
    int timeOut=30;       // Wait for serialUSB, but give up waiting after this many iterations
    while ( !SerialUSB.isConnected() && --timeOut >0 )
    {
        delay(25);
        togglePin(13);
    }
   
     SerialUSB.println("Hi");
   
   }
   
   void loop()
   {
       SerialUSB.println("Hello World!");
   
       delay(200);    
   
       toggleLED();
   }

   I should be able to call SerialUSB.begin() and have it wait. It is hard to believe that isn't something many people want to do while debugging their code.

   Thanks for the help, I appreciate it.

   I couldn't get your code to work no matter how high I made the timeOut. I went as high as 200 and the SerialUSB port was not setup yet. At least that's what I thought at first. After playing for a while I figured that if I open the Monitor window before the loop was done I would see the result. So, your code probably works but only for the window of time where the Monitor is opened before setup gets to print the statements.

   Pressing reset halts the program, I would think that it would restart the process not halt it.

   raymadigan, can you share with me the Maple version of OneWire library? I can't find it in the Internet, and I'm too lazy to port it from Arduino to Maple myself :)

   feurig - Are you having problems posting? Your post is empty when I view the thread.
   A similar thing happened a few weeks ago. Do you think you caused the empty post, or might it be the web browser you are using?
