I tried your method, but still get the same error, disabling port.

What am I doing wrong?

Thanks

The full message I am getting is: Error, disabling serialEvent() for /dev/cu.usbmodem2574541 null

The sketch will get the data one time than it hangs on this message.

Here is my code; I am getting the data from an arduino teensy 3.5 Please help.

Nothing changes. Still zeros and one picture. But previous println(distance) showed the numbers at least.. Could there be wrong datatypes for something?

import processing.serial.*;  
PImage photo1, photo2, photo3;
Serial myPort;  
String data="" ;
int distance;


void setup() {
  size(900, 900); // size of processing window
  photo1 = loadImage("photo1.jpg");
  photo2 = loadImage("photo2.jpg");
  photo3 = loadImage("photo3.jpg");

  myPort = new Serial(this, "/dev/cu.usbmodemfd111", 9600);
  myPort.bufferUntil('\n');
}

void draw() {
  background(0);
  println(distance);
  if (distance <= 20) {
    image(photo1, 0, 0); //display first photography
  } else if (distance > 20 && distance < 40) {
    image(photo2, 0, 0); //display 2nd photography
  } else if (distance >= 40) {
    image(photo3, 0, 0); //display 3rdphotography
  }
}

void serialEvent(Serial myPort) {

  data=myPort.readStringUntil('\n');
  distance=int(data);
}

In consol the range of the sensor is from 5 up to 60 (where is the ceiling). After updating the code the picture still is the same one. And even if the data shows more than 20, it plays photo1.

import processing.serial.*;  
PImage photo1, photo2, photo3;
Serial myPort;  
String data="" ;
PFont  myFont;  
int distance;


void setup() {
  size(900, 900); // size of processing window

  photo1 = loadImage("photo1.jpg");
  photo2 = loadImage("photo2.jpg");
  photo3 = loadImage("photo3.jpg");
  //background(0);// setting background color to black

  myPort = new Serial(this, "/dev/cu.usbmodemfd121", 9600);
  myPort.bufferUntil('\n');
}

void draw() {
  println(data);
  distance=int(data);
  if (distance <= 20) {
    image(photo1, 0, 0); //display first photography
  } else if (distance > 20 && distance < 40) {
    image(photo2, 0, 0); //display 2nd photography
  } else if (distance >= 50) {
    image(photo3, 0, 0); //display 3rdphotography
  }
}

void serialEvent(Serial myPort) {

  data=myPort.readStringUntil('\n');
}

So now I have in processing this code:

import processing.serial.*;  
PImage photo1, photo2, photo3;
Serial myPort;  
String data="" ;
PFont  myFont;  
int distance;


void setup(){
  size(1366,900); // size of processing window

  photo1 = loadImage("photo1.jpg");
  photo2 = loadImage("photo2.jpg");
  photo3 = loadImage("photo3.jpg");
  //background(0);// setting background color to black

  myPort = new Serial(this, "/dev/cu.usbmodemfd121", 9600);
  myPort.bufferUntil('\n');
}

void draw(){
  if(distance>50){
  image(photo1, 0, 0); //display first photograpgy
  }
  else if (40<distance && distance<60) {
  image(photo2, 0, 0);
  }
  else if (distance<40) {
  image(photo3, 0, 0);
}

}

void serialEvent(Serial myPort){

  data=myPort.readStringUntil('\n');

}

It plays only photo3. How can i refer distance to income values? I guess that the income is written in last lines data=myPort.readStringUntil('\n'); ?!

Hi, I am just starting to explore posibilities to make something work in processing via arduino (sensors). On school exhibition I want to make a picture display that shows one image at the time on the wall (with a projector), depending how close or far person is located from distance sensor. This is a sketch of what I am thinking about: To see if it really works, I explored some tutorials that explains how to connect Arduino input with Processing. Currently, I have these codes in both programs: for Arduino:

const int anPin1 = 0;
long distance1;

void setup() {
  Serial.begin(9600);  // sets the serial port to 9600
}

void read_sensors(){
  /*
  Scale factor is (Vcc/512) per inch. A 5V supply yields ~9.8mV/in
  Arduino analog pin goes from 0 to 1024, so the value has to be divided by 2 to get the actual inches
  */
  distance1 = analogRead(anPin1)/2;
}

void print_all(){
  /*
  Serial.print("S1");
  Serial.print("inches");
  */
  Serial.print(" ");
  Serial.print(distance1);
  Serial.println();
}

void loop() {
  read_sensors();
  print_all();
  delay(50); 
}

And for Processing:

import processing.serial.*;  
Serial myPort;  
String data="" ;
PFont  myFont;  
int distance;

void setup(){
  size(1366,900); // size of processing window
  //background(0);// setting background color to black

  myPort = new Serial(this, "/dev/cu.usbmodemfd111", 9600);
  myPort.bufferUntil('\n');
}

void draw(){

  background(0);
  textAlign(CENTER);
  fill(255);
  text(data,820,400);
  textSize(100);
  fill(#4B5DCE);
  text("              Distance :        cm",450,400);
  noFill();
  stroke(#4B5DCE);

}

void serialEvent(Serial myPort){

  data=myPort.readStringUntil('\n');

}

And this distance reading works perfect!

Unfortunately didn’t found any specific example for what i am looking for. So the question is, how can I get, for example, 3 pictures working this way:

if(distance>60){
image(photo1, 0, 0); //display first photograpgy
}
else if (40<distance<60) {
image(photo2, 0, 0);
}
else if (distance<40) {
image(photo3, 0, 0);
}

Do I have to write something like that in draw ()? And how can I get income distance value as number from which depends displayed image? And should I upload any specific library for this? Do i have to write something also again in Arduino code?

Would be great if someone could suggest any examples or codes for this.

Hoping for advise, komats!!

I have my code working well enough, but not I'm having troubles... implementing it. I can manually start my .exe by double-clicking it, but I can't open it through the command prompt or Windows Task Scheduler. Other applications (Notepad, Word, Processing) open through these channels, just not my Processing code exported as an executable file. Any idea if this problem stems from my code or anything Processing related? Here's the code if it helps:

import processing.serial.*;
import ddf.minim.*;

Minim minim;
AudioPlayer stand;
AudioPlayer sit;
AudioPlayer move;

int lf = 10; 
String myString = null;
Serial myPort;   
int sensorValue = 0;

void setup() {

  printArray(Serial.list());

  myPort = new Serial(this, Serial.list()[0], 9600);
  myPort.clear();

  myString = myPort.readStringUntil(lf);
  myString = null;

  minim = new Minim(this);

  stand = minim.loadFile("stand.mp3"); 
  sit = minim.loadFile("sit.mp3");
  move = minim.loadFile("move.mp3");
}

void draw() {

  while (myPort.available() > 0) {

    myString = myPort.readStringUntil(lf);

    if (myString != null) {
      myString = myString.trim();   

      if(myString.length() > 0) {
        println(myString);              
        }

      if(myString.equals("sit")){
            move.pause();
            stand.pause();
            sit.rewind();
            sit.play();

            if(sit.isPlaying() == true)  {
              println("Sound");
            }

        }        
      if(myString.equals("stand")){
            sit.pause();
            move.pause();
            stand.rewind();
            stand.play();

            if(stand.isPlaying() == true)  {
              println("Sound");
            }

        }        
      if(myString.equals("move")){
            stand.pause();
            sit.pause();
            move.rewind();
            move.play();

            if(move.isPlaying() == true)  {
              println("Sound");
            }

        }
      }
    }
  }

I have been working on this game and I tried to make a multiplayer function with a server and a client but I can't seem to get it working with many problems such as a chance that the server will send out a null pointer exception when a client disconnects. I have been able to get the players to show on the other user's screen but it would lag such as when you move, you would move 10 seconds later on the other screen. I can post a GitHub of all the code below but ill write in the important bits below:

GitHub:

https://github.com/rockyhawk64/Trimate.git

CLIENT:

Client Sending Info:

positions(); send = name[0].replaceAll("=", "-") + "=" + x + "=" + y + "=" + bulX + "=" + bulY + "=" + dirr + "=" + gun[0] + '\n'; client.write(send);

Placing Other People On The Screen:

void positions(){ if(masf != null){ for(int i = 0; i <= split(masf,'$').length-1; i++) { String coll[] = split(masf, '$'); String col[] = split(coll[i], '=');if(col[0].equals(client.ip())){ //if the IP is itself }else{ if(col[6].equals("down")){ image(Edown, x+width/2+camX-float(col[2]), y+height/2+camY-float(col[3])); } if(col[6].equals("up")){ image(Eup, x+width/2+camX-float(col[2]), y+height/2+camY-float(col[3])); } if(col[6].equals("left")){ image(Eleft, x+width/2+camX-float(col[2]), y+height/2+camY-float(col[3])); } if(col[6].equals("right")){ image(Eright, x+width/2+camX-float(col[2]), y+height/2+camY-float(col[3])); } } } } }

Recieve Server Message:

void clientEvent(Client client) { masf = client.readStringUntil('\n'); }

SERVER:

import processing.net.*; Server server; String iM = ""; int port = 5204; String players = ""; String positions[] = {}; String col[]; void setup(){ size(800, 400,P2D); server = new Server(this, port); } void draw(){ background(0); Client client = server.available(); if (client != null) { iM = client.readStringUntil('\n'); if(positions.length == 0){ String join[] = {client.ip() + "=" + iM}; positions = join; } String found = null; String ip = client.ip(); if(positions.length != 0){ for(int i = 0; i <= positions.length-1; i++) { if(positions != null){ if(ip.equals(split(positions[i], "=")[0])){ found = str(i); break; } } } } if(found != null){ positions[int(found)] = client.ip() + "=" + iM; }else{ append(positions, client.ip() + "=" + iM); } server.write(join(positions, '$')); } if(positions != null){ col = new String[0]; for(int i = 0; i <= positions.length-1; i++) { if(split(positions[i], "=")[0].equals(split(players, "$"))){ //not used }else{ for(int ii = 0; col.length == positions.length; ii++) { if(ii != i){ append(col, positions[ii]); } } } } positions = col; } } void serverEvent(Server server, Client client) { players = players + "$" + client.ip(); println(client.ip() + " Joined The Game"); } void disconnectEvent(Client someClient) { col = new String[0]; for(int i = 0; i <= split(players, '$').length-1; i++) { if(split(players, '$')[i].equals(someClient.ip())){ for(int ii = 0; col.length == split(players, '$').length; ii++) { if(ii != i){ append(col, split(players, '$')[ii]); } } } } players = join(col, '$'); }

Hi, programmers. I'm still stuck in this code. It seems the "if" statement can't evaluate the readings. So, the video won't stop. I don't know what I'm missing...

Here's the Processing code to play/stop only one video:

import processing.serial.*;
import processing.video.*; 

Serial myPort;
String val;    

Movie video1, video2, video3;

void setup() {
  //fullScreen(SPAN);
  size(640,480);
  video1 = new Movie(this,"estas ahi.mp4");
  //video2 = new Movie(this,"estas lejos.mp4");
  //video3 = new Movie(this,"me gustaria estar aqui.mp4");
  video1.loop();
  //video2.loop();
  //video3.loop();
  String portName = Serial.list()[0];
  myPort = new  Serial(this, portName, 9600);
  myPort.bufferUntil('\n');
}

void serialEvent (Serial myPort) {
  if (myPort.available() > 0) {
    val=myPort.readStringUntil('\n');
  }
  if (val.equals("SI")) {
    video1.stop();
    //video2.stop();
    //video3.stop();
  } else {
    video1.loop();
    //video2.loop();
    //video3.loop();
  }
}

void draw() {
  background(0);
  //image(video1,0,0);
  //image(video2,0,0);
  //image(video3,0,0);
  image(video1,320,120,640,480);
  //image(video2,1600,200,640,480);
  //image(video3,2880,120,640,480);
  println(val);
} 

void movieEvent(Movie video) {
  video.read();
}

Please if you could check and point out what's wrong and so I can continue with the rest. It's my last week before I present this project! :-SS [-O<

What line gives you null?

Anyhow, the problem is sort of both. If you make your life easier, you change both codes. On the arduino side, you send a new line character after sending data. On the Processing side, you read the input data from your serial and you split your data based on the new line char. Then you process each of your tokens in the case you get multiple tokens which you can always check by inquiring for the length of the array in the split function (split/splitTokens ===> Reference)

By the way, notice in your setup: myPort.bufferUntil('\n'); but you are not sending this character in your arduino code. Furthermore, in serialEvent() you should be working with https://processing.org/reference/libraries/serial/Serial_readStringUntil_.html For the time being:

void serialEvent(final Serial s) {
  val = s.readStringUntil('\n');

  if (val==null)
    return;

  String in=split(val, '\n');

  if (in.length!=0) {
    if (in[0].equals("SI")) {  //Processing only first token in case of multiples
      video1.stop();
      video2.loop();
      video3.loop();
    } else {
      video1.loop();
      video2.stop();
      video3.stop();
    }
  }
}

Hi there. I'm trying to play three different videos in three different monitors for an art project. I'm using three LED TVs which I set them in 1280x720 pixels each. The code (and the project) includes an ultrasonic sensor that allows to play or stop the videos, but the main issue is that I can't use the fullScreen(P2D, SPAN); function(?). It gaves me the "Framebuffer objects are not supported by this hardware (or driver)..." error. What can I do?!. I searched for info but I didn't find anything. So...If you remember any thread or info or a past project with this issue, please comment

Thank you thank you thank you!!

Here's the code:

//import processing.serial.Serial;
import processing.video.*;

//Serial myPort;
//String val;   
Movie video1, video2, video3;

void settings() {
  fullScreen(P2D,SPAN);
}

I've used this code for multiple projects at this point without many issues but am now running into an unexpected problem which I am unsure how to solve. I have little to no experience with Processing but was getting some help from people a few months back ago when I started to use this code.

The project is a large LED panel installation on 40 panels, the code will run through processing on a raspberry pi so I am using this pi compatible version someone helped me find. I have one video which almost successfully runs on these 40 panels with a bit of lag (which isn't the worst for the project) but it is not the video I intend to use! In comparing it to the video which I do want to use I am not sure what the difference is. I made the first video which works a few months ago so I can't remember if I did anything different but both videos are made in final cut (mov) and then converted to mp4 online. In final cut I made the dimensions of both videos 640 x 360 and both were H264. The first video moves a bit slower and looks more lo-res but I believe those to be qualities from the original source before I imported and edited in FinalCut.

I believe the problem to be related to the amount/size of data being processed. I should mention that both videos will work according to processing and be recognized by the panels but the issue is that the video I want to use does not play consistently. One teensy may send part of the video to the LEDs mostly correct while another teensy's LEDs start to pick up after 10 seconds and then flickers a spectrum of random colors. None of the teensys seem to be synced up with this second video (though all teensys are mounted on the OctoBoards and connected to each other to sync.)

I'm wondering if anyone has any advice for what to do to the video to make it play correctly.

I have tried using HandBrake to also change some qualities of the video but have no clue what I'm doing really and all of my test have yielded no results.

I also noticed that the flickering happens more when theres a bigger change in color supposed to be happening

I suppose the problem could relate to how many rows I have, not sure, but the other video does seem to be working mostly properly. I am inserting some photos that show the project, some of the panels still need some work so thats why one is pink (wrong RGB ordered lights) and the all white ones just have no data input yet.

Anyone have any ideas?

I hope I entered this code correctly...

The code segments below come from Exploring Arduino Chapter 6. The Aruino code is Listing 6-6, and the processing code is listing 6-7. I run Listing 6-7. in the Processing IDE. But the IDE keeps reporting "Error opening serial port COM3: Port not found". I think its wants me to put the serial library into the same directory with the code directory. But I dont know how to find the serial library, to copy it to there. Please help, I am brand new to Processing.

Here is my Arduino code

    }
    
    void loop() 
    {  // put your main code here, to run repeatedly:
    
      val=map(analogRead(POTpin),0,1023,0,255);  //Read and MAP the A/D value to the color range

Hello strangers, I tried to programm a ball running on my screen in the direction of my Joystick (connected to the Arduino). I wrote the full programm but now I got an error that says: "ArrayIndexOutOfBoundsException: 1". The confusing about this error is, that like every 5 tries to start the programm are a success and I can play my little game as long as I want without any issues. I have no idea what could be wrong so maybe someone of you can help me.

The error has to be in line 28 of my Processing Code.

Arduino Code:

const int xPin = 0;
const int yPin = 1;

int xVal;
int yVal;

String data;

void setup() {
  Serial.begin(9600);
  pinMode(xPin,INPUT);
  pinMode(yPin,INPUT);
}

void loop() {
  xVal = analogRead(xPin);
  yVal = analogRead(yPin);
  data = dataNormalize(xVal,yVal);
  Serial.println(data);
  delay(50);
}

String dataNormalize(int x,int y) {
  String xString = String(x);
  String yString = String(y);

  String data = xString+","+yString;
  return data;
}

Processing Code:

import processing.serial.*;

Serial mySerial;

String myString;
int nl = 10;
float xVal;
float yVal;

int x=500;
int y=50;

Hi, I'm a processing pivot. I have a problem I have a value taken from Arduino, and I visualize it in a graph, but I would also like to be able to visualize it through a numerical table. How can I do? thank you!

import processing.serial.*;
import grafica.*;
Serial myPort;    // The serial port: 
float val;//i datiricevutidalla porta seriale
int xPos=0;
//Stringa di input dalla porta seriale:
int lf = 10;      // ASCII linefeed 
 GPlot plot1, plot2;





void setup() {
  size(440, 520);
 // Create the first plot  Crea il primo grafico
  plot1 = new GPlot(this);
  plot1.setPos(0, 0);
  plot1.setMar(0, 100, 0,100);
  plot1.setDim(300, 300);
  plot1.setAxesOffset(4);
  plot1.setTicksLength(4);

  // Create the second plot with the same dimensions 
  //Crea il secondo grafico con le stesse dimensioni
  plot2 = new GPlot(this);

  // Prepare the points Prepara i punti
  int val =0;
  GPointsArray points = new GPointsArray(val);

  for (int i = 15; i < 13; i++) {
    points.add(i, 20 + 10*noise(i*0.1));
    if(xPos==13){

    }
  }  

  // Set the points, the title and the axis labels 
  // Imposta i punti, il titolo e le etichette degli assi
  plot1.setPoints(points);
  plot1.setTitleText("Temperature");
  plot1.getYAxis().setAxisLabelText("MASSA ARIA (?)");
  plot1.getXAxis().setAxisLabelText("APERTURA VALVOLA (mm)");


  plot1.activatePanning();
    myPort = new Serial(this, "com3", 9600);
  myPort.bufferUntil(lf);

}




void draw() {
  background(255);
  println(val);
  fill(0);
  text("val  "+val,200,450);
 //Disegna la prima trama 
  plot1.beginDraw();
  plot1.drawBox();
  plot1.drawXAxis();
  plot1.drawYAxis();
  plot1.drawTitle();
 //plot1.drawPoints();//pallinorosso sul valore
  plot1.drawGridLines(GPlot.BOTH);
  plot1.drawLines();
  plot1.endDraw();
  }




  void serialEvent (Serial myPort) {
      //  // get the ASCII string:
  //  // ottiene la stringa ASCII: 
   String inString = myPort.readStringUntil('\n');

    if (inString != null) {
  //    // trim off any whitespace:

      inString = trim(inString);

     val = float(inString);
    println(val);
   }
  }

void mousePressed(){
   GPoint lastPoint = plot2.getPointsRef().getLastPoint();

  if (lastPoint == null) {

       plot1.addPoint(xPos, +val, "(" + str(xPos) + " , " + str(val) + ")");

  } 
  else if (!lastPoint.isValid() || sq(lastPoint.getX() - xPos) + sq(lastPoint.getY() + val) > 2500) {

  }

  if( mouseButton == LEFT ) xPos+=1; 

  fill(0);
   text ("val"+val,200,480);
}

I have a simple push button connected to pin 2 on my arduino. I can read this value and print it to the serial monitor without any trouble:

``` int pushButton = 2;

void setup() {
  Serial.begin(9600);
  pinMode(pushButton, INPUT);
}

void loop() {
  int buttonState = digitalRead(pushButton);
  Serial.println(buttonState);
  delay(1);        // delay in between reads for stability
}

```

This prints a value of 0 when the button is not pressed, and 1 if it is.

In processing I want to check if the value is zero or one, and perform some conditional logic. But I can't get the equality right:

``` Serial myPort; String resultString;

void setup(){
  size(640,480);
  printArray(Serial.list());
  String portName = Serial.list()[2];
  myPort = new Serial(this,portName,9600);
  myPort.bufferUntil(10);
}

void draw(){
  //
}

void serialEvent(Serial myPort){
  String inputString = myPort.readStringUntil(10); //until newline or ("\n");
  inputString = trim(inputString);
  println(inputString);
  if (inputString == "1"){ //this doesn't work, even though println will render ("1") plus the newline if button is pushed.
    println("on");
  } else {
    println("off");
  }
}

```

How do I set up this conditional to do one thing if the button is pushed, and another if it is not?

I've tried converting the string to an int using

inputInt = Integer.parseInt(inputString);

and then performing the check, but it didn't work.

Hello, everyone. I am using an Arduino MEGA 2560 and ArduCAM OV2640 to take a JPEG picture and display it on my PC through a Processing sketch. The current Arduino and Processing sketches let me take single shots only. I am wondering how I can make it so the camera will take pictures continuously and display it on the PC, similar to a video stream. Here are the sketches, courtesy of Vernel. (https://github.com/Vernel/ArduCAM_OV562

long picNum = 0;



void setup() {

  size(640, 480);



  // List all the available serial ports

  // if using Processing 2.1 or later, use Serial.printArray()

  printArray(Serial.list());





  // Change the 0 to the appropriate number of the serial port

  // that your microcontroller is attached to.

  myPort = new Serial(this, Serial.list()[0], 250000);



  // read bytes into a buffer until you get a linefeed (ASCII 10):

  myPort.bufferUntil('\n');



  // draw with smooth edges:

  smooth();



  img = createImage(320, 240, RGB);

  img.loadPixels();

  //frameRate(600);

  myPort.write(0x10);
}
