Start up issue

[dskogman]

I have an extended graphics sketch that does not initialize properly when initially plugged into a USB or a new sketch uploaded. It just displays the default screen. If I then start the terminal window the 4Duino resets and starts properly. It is a simple sketch with a gauge on it. Any ideas?

Hi,

You might have uncommented this line:

 while (!Serial) ;

Which will wait for serial connection, just comment this line to disable it.

I hope this helps,

That appears to be the issue. Thx
