I don't understand why split() is always setting the last data value read in to be zero. Can anyone advise?
EDIT: I do see the last value if I split to strings, instead of converting with int(). So the last string in the line contains a newline, and int() sees a non-numeric value and sets it to zero?

Here is the relevant section of my code:

1. import processing.serial.*;  // serial library
   
   Serial myPort;       // The serial port
   String inBuffer = null;  // one line of data from serial port
   
   void draw() {
   int[] dat; // array of numbers read in on one line from serial port
   
     if (inBuffer != null) {  // wait for new data on the serial port
   
       print("SERIAL:" + inBuffer);  // show the line of serial input
       dat = int(split(inBuffer, ','));  // parse comma-separated number string into numbers
       println("DAT_IN:" + dat[0] + "," + dat[1] + "," + dat[2] + "," + dat[3] + "," + dat[4]);
       println(); 
       // [... plus other stuff ...]
     }
   }
   
   void serialEvent(Serial p) {
     inBuffer = p.readString();  // store serial port buffer in global var inBuffer
   }
   

and here is a sample of the output I get. Note how the last number in the line, 125 or 123, always becomes 0.

1. SERIAL:0,0,1,629,125
   DAT_IN:0,0,1,629,0
   
   SERIAL:0,1,5,629,123
   DAT_IN:0,1,5,629,0
