Using two different readStringUntil "characters"

Processing Electronics (Arduino, etc.)

Alright so nothing is working yet. I’m currently trying it on a simpler scale – using potentiometer and drawing lines. It’s similar anyway, so I thought I’d figure this thing out using potentiometer

I just have a question: Does the value for the array index reset to 0? From as far as I know (which is probably wrong :thinking:), the splitTokens() parses a string and puts it into array as

 val [strIndex0]

where this is the first value from the serial.

Now, as the serial is being read, given that it has 2 values, does the index reset after \n?

On another note…I’m working on this and this is what I have

import processing.serial.*;

Serial port;
float[] coords = new float [2];

float x, y;
float px, py;

void setup(){
  background(1);
  port = new Serial (this, "COM12", 115200);
}

void serialEvent(final Serial port){
  coords = float(splitTokens(port.readStringUntil('\n')));
}

void draw(){
  if(port.available() > 0){
    index = 0;
    serialEvent(port);
    x = coords[0];
    y = coords[1];
    line(px, py, x, y);
    px = x;
    py = y;
  }
}

The Arduino:




void setup() {
  Serial.begin(115200);
}

void loop() {
  int x = analogRead(A1);
  int y = analogRead(A0);

  int x1 = map(x, 1023, 0, -10, 10);
  int y1 = map(y, 0, 1023, -10, 10);

  Serial.print(x1); Serial.write('\t');
  Serial.print(y1); Serial.write('\t');
  Serial.println('\n');

}

Is the arduino side correct? I wont want to be referring to tsv and newline and then it turns out I’m wrong :disappointed:
