  @Gordon Thanks
  i'll try tomorrow
  I'm able to clean the output, but i was looking for a way to have a clean output (easer to explain the code to beginners)

  I had a switchto switch on/off setConsole on USB or on an other Serial
  I use print non console.log

  i've tried this

  let laser;
  
  function lis(){
    let somme=0;
    var dist = laser.performSingleMeasurement().distanc­e;
    print(dist);
    //console.log(dist);
    //console.log("distance: ",dist," lissée:",somme/table.length);
    analogWrite(LED1, (1000-dist)/1000, { soft:true, freq:200 });
  }
  
  function onInit() {
    //Serial1.setup(115200);
    I2C2.setup({sda:B3,scl:B10});
    laser = require("VL53L1X").connect(I2C2);
    print("init");
    digitalWrite(B4,1); // set XSDN -> turn the sensor on
    setInterval(lis, 150);
    pinMode(A6, 'input_pulldown');
    setWatch( function (e) {
      console.log(e.state);
      if (e.state) {
        Serial1.setConsole();
      } else {
        USB.setConsole(true);
      }
    }, A6, { repeat:true, edge:"both", debounce: 100 });  
  }
  

  if i move the console to another Serial...
  nothing come in Processing
  otherwise my output is always crippy

  1587 is my number

  :v

  Any idea

  USB object is an instance of Serial
  https://www.espruino.com/Reference#l__gl­obal_USB

  There is no exemple! to initiate the USB

  have you one?

  should i use this?

  E.on('init', function() {
    USB.setConsole();
  });
  

  Or USB.setConsole(true); ?

  regards

  I know this certainly a stupid question.

  i'm prototyping something for my students
  i use a V53L1X connected to my pico.
  i would like to transfer the datas to Processing.
  i connect the Pico on the usb plug.

  should i use
  console.log or print
  to transmit my data?

  should i initialize a serial port?
  Serial1.setup(115200);

  some time the console send error from the program (i2c init);
  i'm really confuse, it should be simple, but it's not.
  sometime nothing arrive to Processing.

  i've got an other problem, the string received start with an invisible char and [J

  How should i do to have a clean string with distance value?

  Could i use midi thru usb to send datas?
  i should split my value [0-4000] in 2 set of 7bits (midi value)

  thanks for your help

  let laser;
  
  function lis(){
    let somme=0;
    var dist = laser.performSingleMeasurement().distanc­e;
    //print(dist);
    console.log(dist);
    //console.log("distance: ",dist," lissée:",somme/table.length);
    analogWrite(LED1, (300-dist)/300, { soft:true, freq:200 });
  }
  
  function onInit() {
    Serial1.setup(115200);
    I2C2.setup({sda:B3,scl:B10});
    laser = require("VL53L1X").connect(I2C2);
    console.log("init");
    digitalWrite(B4,1); // set XSDN -> turn the sensor on
    setInterval(lis, 80);
  }
  

  and the processing sketch

  import processing.serial.*;
  
  Serial myPort;  // Create object from Serial class
  int val;      // Data received from the serial port
  
  void setup() 
  {
    size(200, 200);
    // le port de l'espruino sur mon mac est en 3
    String portName = Serial.list()[3];
    myPort = new Serial(this, portName, 115200);
  }
  
  void draw(){
    while (myPort.available() > 0) {
      String inBuffer = myPort.readStringUntil('\r');
      if (inBuffer != null) {
        String[] q = splitTokens(inBuffer, "[J");
        if (q.length > 1) {
          val = int(float(q[1]));
          println(val);
        }
      }
    }
  }

  Thanks @Robin,
  I started with the same example, but i missed the ‘toString()’ to convert my counter in String in my attempt.

  It works now...

  thanks again.

  Hello,

  I'm looking for to store a var in a permanent way (power off) and load at start (power on)
  i saw that @Gordon implement a way to store data since 2v05, but the example code is for log datas (implementative way) and it seems a beat complex just for store a counter var.

  have you a simple example to implement a counter (with a long type) storage over power-down?

  I've tried

  var memoire = require("Storage");
  [...]
  let NumPoemeEncours = memoire.read("num"); // numero encours
    if (NumPoemeEncours == null || NumPoemeEncours == undefined  || NumPoemeEncours == "") {
        NumPoemeEncours = 1;
        console.log("numero du poeme inconnu", memoire.read("num"));
        memoire.write("num",NumPoemeEncours);
        console.log("numero du poeme connu", memoire.read("num"));
    }
  console.log("NumPoemeEncours:",NumPoemeE­ncours);
  

  but it does not works!

  what i'm doing wrong?

  thanks for your time.

  Do you need this at the same time? Because it would potentially be really bad news to attach power to the USB power input and then plug it into your PC as well.

  Not at the same time of course, but the possibility to scratch the paint and uncover the mini usb pads and sold 2 wires seem to be a bit dangerous if i need to plug the usb in my computer to update code.

  there is a samsung travel charger with slim wire in black or white, and is cute and strong enough to power a simple led matrix.
