Trying to wrangle serial data from an Arduino

Processing Electronics (Arduino, etc.)

Hello,

It is often helpful to write short snippets of test code for better understanding.
Then integrate these in to a larger project.
I do this often.

For example:

// Processing Array Study
// GLV
// 2021-10-10

String [] testData = new String [2];

int [][] test = new int[4][10];

void setup() 
  {
  testData [0] = "233 230 254 296 357 436 486 513 519 528"; // A single String of data
  testData [1] = "000 111 222 333 444 555 666 777 888 999"; // A single String of data
  printArray(testData);
  println();
  
  String[] strData = splitTokens(testData[0], " ");
  printArray(strData);
  println();
  
  String[] strData2 = split(testData[1], " ");
  printArray(strData2);
  println();
  
  int[] intData = int(split(testData[0], " "));
  printArray(intData);
  println();
  
  int[] intData2 = int(splitTokens(testData[1], " "));
  printArray(intData2);
  println();  
  
  test[0] = intData;
  printArray(test[0]);
  println();
  
  test[1] = intData2;
  printArray(test[1]);
  println();
  
  for(int i = 0; i<2; i++)
    { 
    for(int j = 0; j<10; j++)
      {
      print(test[i][j], " ");  
      }
    println();  
    }
  println();   
    
    
  for(int i = 0; i<4; i++)
    { 
    for(int j = 0; j<10; j++)
      {
      test[i][j] = j + i*4;   
      }
    }
  println();     

  for(int i = 0; i<4; i++)
    { 
    for(int j = 0; j<10; j++)
      {
      print(test[i][j], " ");  
      }
    println();  
    }   
    
for(int i = 0; i<4; i++)
    { 
    for(int j = 0; j<10; j++)
      {
      print("["+i+"]"+"["+j+"]", test[i][j], "" );  
      }
    println();  
    }       
  }
