You can do that! Nice to see you putting a lot of thought into this.

You will have to frame the data string you are sending correctly and terminate with a ‘/n’ (in my example.

Example of received string only:

// Trim and split an data string Rx from Arduino.
// v1.0.0
// GLV 2020-MM-DD
                  
void setup()
  {
  background(0);
  size(400, 500);
  // Data packet received from Arduino: 
  //                 t1,  d1, t2,  d2, ... t=time, d=data 
  String inString = "1000,250,1100,300,1200,375,1300,380,1400,375,1500,300,1600,250,1700,200\n"; // '\n' is a linefeed character 
  print(inString);
  
  inString = inString.trim(); //Works!
  inString = trim(inString); //Works!
  print(inString);
  println("end"); //confirms that '/n' was removed!
  
  println();
  String[] list = split(inString, ',');
  printArray(list);
  
  int [] data = int( split(inString, ',') );
  printArray(data);
  
  stroke(255, 255, 0);
  strokeWeight(5);
  
  for(int i = 0; i< data.length; i+=2)
    {
    point((data[i]-1000)/5, data[i+1]);   
    }
  }

Next step I leave with you. :slight_smile:
