Using two different readStringUntil "characters"

Processing Electronics (Arduino, etc.)

Well, I don’t have any Arduino hardware and neither even seen 1 in front of me yet! :woozy_face:

So I can only do blind coding in the dark for you. :dark_sunglasses:

Theoretically, an Arduino C code like this 1: :thinking:

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

void loop() {
  const int x = map(analogRead(A1), 0, 1023, -10, 10);
  const int y = map(analogRead(A0), 0, 1023, -10, 10);

  Serial.print(x);    // "-5"
  Serial.write('\t'); // '\t'
  Serial.println(y);  // "10" + "\r\n"

  delay(2);
}

Should expect to send an output similar to this 1 on each of its loop(), right: :grey_question:

String tsv = "-5" + '\t' + "10" + "\r\n";
println(tsv); // -5      10

int[] vals = int(splitTokens(tsv));
println(vals); // [0] -5  [1] 10

exit();

So AFAIK, a Processing Java code like this 1 should hopefully work for your case: :pleading_face:

import processing.serial.Serial;

static final int VALS = 2;
int[] vals = new int[VALS];

void setup() {
  size(800, 600);
  noLoop();

  stroke(-1);
  clear();

  final String[] ports = Serial.list();
  printArray(ports);

  new Serial(this, "COM12", 115200).bufferUntil(ENTER);
}

void draw() {
  println(vals);
}

void serialEvent(final Serial s) {
  vals = int(splitTokens(s.readString()));
  redraw = true;
}
