Some notes, wordList is the input in the main class using processing 3. The method I am trying to use is comparing the reversed version of the string with itself to see if they are the same. Hope you can help, thanks!

Boolean isPalindrome(String wordList) { String a; a=""; for(int i=0; i<wordList.length();i++) { a = a + wordList.charAt(wordList.length()-1-i); } if(a == wordList) { println(); print("Its a palindrome"); fill(0); textSize(14); text("Its a palindrome",80,170); return true; } else { println(); print("Its not a palindrome"); fill(0); textSize(14); text("Its not a palindrome",80,170); return false; }

When I store something in the hashmap, use hashmap.get() to get the float object, I can't seem to write to the original object. In this example I try to get and modify the original float1 variable without success. It seems to modify a new float stored in the hashmap in test2, test1 does nothing.

Float float1 = 1.1;
HashMap<String, Float> hm = new HashMap<String, Float>();

void setup() {
  hm.put("float1", float1);

  Float f1 = hm.get("float1");
  f1 = 5.5;

  println("test1");
  println("float1: " + float1);
  println("hashMap float1: " + hm.get("float1"));
  println("both should  should be " + f1);
  println();

  println("test2");
  hm.put("float1", f1);
  println("float1: " + float1);
  println("hashMap float1: " + hm.get("float1"));
  println("both should  should be " + f1);
  println();
}

Here's the output

test1
float1: 1.1
hashMap float1: 1.1
both should  should be 5.5

test2
float1: 1.1
hashMap float1: 5.5
both should  should be 5.5

I'm trying to learn the JSON and it's intricacies.

I'm using the JSONget example as a starter.. I want to do conditionnals, but it never returns true.

Even using the debugger, it all seem ok and the same, t and a will give type java.lang.String = "Wilbert"

what am I missing here? I'm confused..

Thanks for the help

``` int pushButton = 2;

void setup() {

  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.

Isn't the format of dataPath String? Although I wrote the following code, but A wasn't called. Why isn't the println("A") called?

String data_path = dataPath("test"); if(data_path == dataPath("test")) { println("A"); } else { println("B"); }

Why won't it switch to the tableOfContents screen when you type in "username" and "password".

I need to stop a video when the PIR is "On" (Detects motion) and to play that video if the PIR is "Off".

Checking the Processing and Arduino websites, examples and references I couldn't figured out what I'm doing wrong. Please let me know if something is missing or left. Thanks in advance for any help!

This is the Arduino Code (copied from Arduino and Processing communication tutorials found on the web):

/*
   PIR sensor tester
*/

int ledPin = 13;                // choose the pin for the LED
int inputPin = 2;               // choose the input pin (for PIR sensor)
int pirState = LOW;             // we start, assuming no motion detected
int val = 0;                    // variable for reading the pin status

void setup() {
  pinMode(ledPin, OUTPUT);      // declare LED as output
  pinMode(inputPin, INPUT);     // declare sensor as input

  Serial.begin(9600);
}

void loop() {
  val = digitalRead(inputPin);  // read input value
  if (val == HIGH) {            // check if the input is HIGH
    digitalWrite(ledPin, HIGH);  // turn LED ON
    if (pirState == LOW) {
      // we have just turned on
      Serial.println("Motion detected!");
      // We only want to print on the output change, not state
      pirState = HIGH;
    }
  } else {
    digitalWrite(ledPin, LOW); // turn LED OFF
    if (pirState == HIGH) {
      // we have just turned of
      Serial.println("Motion ended!");
      // We only want to print on the output change, not state
      pirState = LOW;
    }
  }
}

And here is the Processing code:

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

Serial myPort;
String val;    

Movie video;

void setup() {
  size(640,480);
  video = new Movie(this,"sujeto1.mp4");
  video.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=="Motion detected!") {
    video.stop();
  } else {
    video.loop();
  }
  println(val);

}
void draw() {
  background(0);
  image(video,0,0);

} 

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

So I've been working on setting up a Client/Server system, and I'm trying to get them to send Strings to each other. However, I was running into a very strange issue: whenever I set some variable equal to readString(), the program seems unable to recognize it as a string. After toying around with it for a while, I wrote a minimalist code to demonstrate the source of my confusion...

First, the Server code:

import processing.net.*;

Server server;

void setup() {
  size(600,400);
  server = new Server(this, 5204);
}

void draw(){
  Client client = server.available();
  if (client != null) {
    String msg = client.readString();
    println(msg);
    println(msg == "k");
  }
}

Next, the Client code:

import processing.net.*;

Client client;

void setup() {
  size(400, 200);
  client = new Client(this, "127.0.0.1", 5204); //I replaced 127.0.0.1 with my IP address in the actual code
}

void draw() {
}

void mouseClicked(){
  client.write("k");
}

I would have expected it to return "k", then "true", but it returns "k", then "false". Is readString() not actually a string or something? What's going on?

Any and all help would be appreciated.

I have a little problem with my programme.

I would like to control if the text in the textfield is good or not but it doesn't work.

I can get the text in the textfield but when I want to check if it's good it doesn't work.

Some one has a solution for me please?

The code is here :

String Reponse = "oui";

import controlP5.*;

ControlP5 cp5;

void setup() {
  size(700,400);

  PFont font = createFont("arial",20);

  cp5 = new ControlP5(this);

  cp5.addTextfield("input")
     .setPosition(20,100)
     .setSize(200,40)
     .setFont(font)
     .setFocus(false)
     .setColor(color(255,0,0))
     ;
      cp5.addBang("clear")
     .setPosition(240,170)
     .setSize(80,40)
     .getCaptionLabel().align(ControlP5.CENTER, ControlP5.CENTER)
     ;    

    textFont(font);
}

void draw() {
  background(0);
  fill(255);
  text("Ecrivez votre réponse ici",20,90);
  text(cp5.get(Textfield.class,"input").getText(), 360,130);
  if(cp5.get(Textfield.class,"input").getText() == Reponse){
    text("Vrai",20,20);
  }
}

public void clear() {
  cp5.get(Textfield.class,"input").clear();
}

I get an error on line 20 "cannot convert from int to String"

i have a string 12345.xxx

println(string.substring(string.length() - 3); // prints xxx to console

next line is:

if (string.substring(string.length() - 3) != "xxx")  {
  println(string + "yyy");
}

this is what prints to console:

12345.xxxyyy

It seems the if does not recognize the comparison!

I can't figure out why

Print out to Console:

`Panel:1 Panel???? true Panel = 1

Panel:2

Why the second time 'elements[0].equals("Panel")' is false?

void show(String side){ if(side == "right"){ rect(rPx, rPy, paddleWidth, paddleHeight); rPy += yspeed; } if(side == "left"){ rect(lPx, lPy, paddleWidth, paddleHeight); lPy += yspeed; } }

Depending on the parameter the rectangels should be on the left or right side. It's working just fine, I just don't feel like it's nice code...

import processing.net.*; 
Client myClient; 
String inString;
byte interesting = 10;

void setup() { 
  size (300, 100);
  myClient = new Client(this, "127.0.0.1", 12345); 
} 

void draw() { 
  
  if (myClient.available() > 0) { 
    background(0); 
    inString = myClient.readStringUntil(interesting); 
    println(inString); 
    if (inString.equals("hello") == true) { // -this not working...
      exit();
    } 
  } else {
    background(0,25,59);
  }
}

and server:

import processing.net.*;

Server s; 
Client c;
String input;
int data[];

void setup() { 
  size(450, 255);
  background(204);
  s = new Server(this, 12345);
} 

void draw() { 
  if (mousePressed == true) {
    s.write("hello\n");
  }
}

So with processing i'm reading a text file into a string. I only want to send data to the serial port if there is new data in the text file. So in the setup part i created a string[] lines that loads into a string the content of the text file.

In the main loop i create a string[] linesTemp that loads the content of the same file. Then i make a if to compare the two strings. If the two strings are equal i print "same". The issue is that the two strings have the same values but i don't know why it doesn't go into the if statement and print "same" in the console. Thanks !

Here is my code :

import processing.serial.*;
import java.io.*;
Serial myPort;

String[] lines; 

int b =0;
int c =0;

void setup() {
  //Make sure the COM port is correct
  myPort = new Serial(this, "COM5", 9600);
  myPort.bufferUntil('\n');
  lines = loadStrings("matrice.txt");
}

int counter=0;

void draw() {


  String[] linesTemp = loadStrings("matrice.txt");


  for (int a=0; a<(lines.length); a++)
  {
    println("ligne : ", b++, lines[a]);
    println("ligneTemp : ", c++, linesTemp[a]);

    if (linesTemp[a] == lines[a])
    {
      println("same");
    } else if (linesTemp[a] != lines[a]) {

      lines[a] = linesTemp[a];
      myPort.write(""+linesTemp[a]);
    }
  }
  delay(1000);
}

I've got 2 csv files on my hand ; the first listing restaurants, with 3 columns(coordinate x, coordinate y, restaurant name) and another listing deliveries (coordinate x, delivery coordinate y , name of the restaurante the delivery was done by).

I need to : 1) Display the number of deliveries made for each restaurant. 2) The average distance of the deliveries for each restaurant (distance being calculated by this formula = sqrt(sq(x1-x2)+sq(y1-y2) at least I figured something out :p)

For the first, I made a class which looks like this :

Then I'm trying to go trought the deliveries table and change the arraylist of objects so that when the string happens to be the same in a row and the arraylist object the object counts gets to +1. But it doesn't seem to work. Any tips appreciated for the step 2, also.

Hello world
abc
123

And get this:

["Hello World", "abc", "123"]

How can I do this?

It goes something like this (I will just paste the relevant code):

    void setup(){
      size(300, 300);
      background(255, 0,0);
    }

    void draw(){

    String curr = "0";
      curr = str(key); //parenthesis (pause!)

      if(curr == "p"){
        background(0);
      }
      if(curr == "q"){
        background(255);
      }

      println(curr + " is the current key");
    }

println shows me that the key is working in conversion, but for some reason I can't seem to get the function working. I've trawled the forums but haven't come across this - I would be very grateful if anyone can point me to an answer in another forum post, or let me know if you can spot what I'm doing wrong!

Thanks!

My problem is when it receive "node1" from sender through xbee, the condition is aborted.. BUT, when i manually write in serial, the condition is worked.. i think the data sent by sender is not actually "node1"..even when i Serial.print(), it shows ""node1" physically.

this is receiver node:

whatever, Here is my Question.

//Printing it, I see it's the same

The console says:

I just installed LUBUNTU 16-04 with a running arduino IDE. No problem.

Now I would like to install processing3. I have it running.

But my adxl345 read out in pitch-roll give the above mentioned error.

Already looked on the internet for possible solutions s.a. i must be mention of the group etc.

Al I treid nothing works.

Situation arduino for linux and processing3

linux prog is LUBUNTU 16-04 and linux32 4.4.0.22

Who has the solution. Help is very much apriciated.

Kind regards,

ilioSS

btw arduino uses ttyUSB0 serial port
