Serial data from Arduino to Processing does not update

Hello,

This is what your code (with some added code) is doing:

String [] sensors0;
int [] sensors1;

void setup() 
  {
  String s = ",0,0,1,0,2,0,3,0,4,0,5,0,6,0,7,0,8,0,9,0,10,0,11,0";
  //https://www.arduino.cc/reference/en/language/functions/communication/serial/println/  
  String ard = s + "\r\n";
  print(ard);
  
  //myString = myPort.readStringUntil('\n');
  String myString = ard;

  if (myString != null) 
    {
    myString = trim(myString);
    println(myString);
    sensors0 = (split(myString, ','));
    printArray(sensors0);
    sensors1 = int(split(myString, ','));
    printArray(sensors1);
    }
    
  println(int(""));
  }
Console output: 
,0,0,1,0,2,0,3,0,4,0,5,0,6,0,7,0,8,0,9,0,10,0,11,0
,0,0,1,0,2,0,3,0,4,0,5,0,6,0,7,0,8,0,9,0,10,0,11,0
