transferring an array to processing?

Projects Programming
1

hi guys,
i have made a robot that does adaptive mapping on a 15x15 grid,
but i want the robot to be able to transfer the map to the computer,

i have no idea about the most economical way/ any way.

here is the part in the arduino

 int Map[15][15];

void setup() 
{ 
  Serial.begin(9600);
}

void sendMap() 
{
for (int H=0; H<15;H++)
    {
      for (int W=0; W<15;W++)
      {
        delay(5);
        Serial.println(Map[H][W]);
      }
    }
}

processing

import processing.serial.*;     // import serial library
Serial myPort;                  // declare a serial port
int[][] distances = new int[15][15];
float maxDistance;
int x, y;  
void setup() {
  // setup the background size, colour and font.
  size(15*30+30, 15*30+30);
  background (0); // 0 = black
  // setup the serial port and buffer
  myPort = new Serial(this, "COM10", 9600);//i am using com port 10
  myPort.bufferUntil('\n');
}
/* draw the screen */
void draw() {
  for(int i=0; i<15; i++) 
  {
    for(int j=0; j<15; j++) 
    {
      switch (distances[j][i])
      {
      case 1: // if the value in the array is a 1 then change the background colour
        {
          noStroke();
          fill(0, 0, 254);
          rect(j*30+10,i*30+10,20,20);
          fill(200, 200, 200);
          text(Integer.toString(distances[j][i]), j*30+10, i*30+10, 40, 40);
        }
        break;
      default:
        {
          noStroke();
          fill(100, 100, 100);
          rect(j*30+10,i*30+10,20,20);
          fill(200, 200, 200);
          text(Integer.toString(distances[j][i]), j*30+10, i*30+10, 40, 40);
        } 
        break;
      }
    }
  }
}


/* get values from serial port */
void serialEvent (Serial myPort) {
  String xString = myPort.readStringUntil('\n');  // read the serial port until a new line
  if (xString != null) {  // if theres data in between the new lines
    xString = trim(xString); // get rid of any whitespace just in case
   
    distances[x][y] = Integer.parseInt(xString); // set the values to variables
    x++;

    if (x==15)
    {
      x=0;	
      y++;
      if (y==15)
        y=0;
    }
  }
}

Glad you found time to share your insight.

which insight would that be XD

i am still getting it to work every time, and i have been down the coast for easter,
and i am going to add a Bluetooth and make a vid when i have it working properly

Do you have a reading comprehension issue?

i have no idea about the most economical way/ any way.

What did you do to solve your problem? What should other people who have a similar issue, and who find your thread, do? Solve it themselves, too?

ok,
it is up,
i wanted to know if he wanted the adaptive mapping code or the transfer code
