We are about to switch to a new forum software. Until then we have removed the registration on this forum.
I have a program which simply reads the input from an Arduino on COM4. It simply sends some decimal numbers, and my program draws something.
Is there someway that I can "emulate" the Arduino, that means
import processing.serial.*; float bla = random(255); String toWrite = ""+bla; Serial myPort; println(Serial.list()); // Open the port you are using at the rate you want: myPort = new Serial(this, Serial.list(), 9600); myPort.write(toWrite);
running this code, without ArrayIndexOutOfBounds 0 on line 10, without an Arduino connected to the PC.
