I need to connect and disconnect the serial port while my draw() loop is running.

I can connect once (in setup()) using:

Serial(close);

How can I re-connect again in draw()?

 

 

The option for using an external editor has now been removed from the Preferences dialog.

I modified the line: editor.external =true in preferences.txt and restarted Processing, but it was still possible to edit in Processing. Is this a known bug, or am I doing something wrong?

In the following example, why does the character array 'abcd' print in a different location to the string "efgh"?

 

size (100,100);
textFont(createFont("Arial", 20));
char[] c = {'a', 'b', 'c', 'd'};
String d = "efgh";
text(c, 0, 4, 40, 40);
text(d, 0, 4, 40, 40);
