I'm working on a program that will be sending a text file to a machine over serial communication. So far the program looks great however I have not been able to find how to program the application to start and stop bits, and even or odd encoding. Is this possible to be done using the serial library? Again this is still a work in progress.

Please advise, - M

My code so far:

//import processing.serial.*;
import controlP5.*;
import java.io.*;

//Serial myPort;
ControlP5 cp5;
int waitTime = 500;
boolean connectionStatus = false;
String fileName = "textfile.txt";
char endChar = '\n';
boolean stopTrigger = false;
Textarea consoletext;
//Println console;

void setup()
{
  noStroke();
  size(800, 520);
  cp5 = new ControlP5(this);
  cp5.enableShortcuts();

  cp5.addTextlabel("title")
    .setText("Monarch Interface Application")
    .setPosition(10, 10)
    .setFont(createFont("Arial", 22))
    .setColor(color(255, 255, 250, 255))
    ;
  cp5.addButton("stopButton")
    .setSize(90, 50)
    .setFont(createFont("arial", 22))
    .setCaptionLabel("STOP")
    .setPosition(20, 70)
    ;
  cp5.addButton("sendButton")
    .setFont(createFont("arial", 22))
    .setSize(90, 50)
    .setCaptionLabel("SEND")
    .setPosition(20, 140)
    ;

  cp5.addTextfield("waitTimeInput")
    .setId(6)
    .setPosition(20, 420)
    .setSize(200, 35)
    .setFont(createFont("arial", 20))
    .setAutoClear(false)
    .setCaptionLabel("Wait per Line")
    .setText(Integer.toString(waitTime))
    ;
  cp5.addTextfield("fileNameInput")
    .setId(6)
    .setPosition(20, 340)
    .setSize(200, 35)
    .setFont(createFont("arial", 20))
    .setAutoClear(false)
    .setCaptionLabel("Filename")
    .setText(fileName)
    ;
  cp5.addTextlabel("statusLabel")
    .setText("Status:")
    .setPosition(20, 220)
    .setFont(createFont("Arial", 20))
    .setColor(color(255, 255, 250, 255))
    ;
  cp5.addTextlabel("statusLabelb")
    .setText("DISCONNECTED")
    .setPosition(55, 255)
    .setFont(createFont("Arial", 20))
    .setColor(color(255, 255, 250, 255))
    ;
  cp5.addTextlabel("ctext")
    .setText("Console | Serial Injection")
    .setPosition(365, 3)
    .setColor(color(200, 0, 0, 255))
    .setFont(createFont("Arial", 18))
    ;
  consoletext = cp5.addTextarea("txt")
    .setPosition(370, 30)
    .setSize(420, 480)
    .setFont(createFont("", 12))
    .setLineHeight(14)
    .setColor(color(255, 255, 255, 255))
    .setColorBackground(color(100, 100))
    .setColorForeground(color(255, 100))

    ;

  //console = cp5.addConsole(consoletext);
  println("SYSTEM: GUI Loaded");
}

void draw()
{
  background(0);
  fill(255);
}

public void sendButton() {
  stopTrigger = false;
  sendCode();
}
public void stopButton() {
  stopTrigger = true;
}


void sendCode() {
  try {
    FileInputStream fstream = new FileInputStream(sketchPath(fileName));

    DataInputStream in = new DataInputStream(fstream);
    BufferedReader br = new BufferedReader(new InputStreamReader(in));

    String strLine;
    while (((strLine = br.readLine()) != null) && (stopTrigger != true)){
      //myPort.write(strLine +endChar);
      println("Sent: " +strLine);
      //delay(waitTime);
      Thread.sleep(waitTime);
    }
    in.close();
  }
  catch(Exception e) {
    println("SYSTEM ERROR:");
    println(e.getMessage());
    System.err.println("Error: " +e.getMessage());
  }
}

void controlEvent(ControlEvent event) {
  if (event.isAssignableFrom(Textfield.class)) {
    if ("waitTimeInput".equals(event.getName())) {
      waitTime = Integer.parseInt(event.getStringValue());
      println("*   Wait Time Updated: " +waitTime);
    }
    if ("fileNameInput".equals(event.getName())) {
      fileName = event.getStringValue();
      if (fileName.endsWith(".txt")) {
        println("*   Filename Updated: " +fileName);
      } else {
        fileName = fileName += ".txt";
        println("*   Filename Updated: " +fileName);
      }
    }
  }
} //End of controlEvent

The method ellipse() is undefined for the type TestClass

I first thought like I need to import processing.core.PApplet; but that doesn't seem to work for me :/

regards, TPRammus

EDIT: Thanks to the answers, I edited my code. Now I fist pass "this" to a static (PApplet) variable "PA" in my class. And I can use "PA" like this: PA.ellipse(1, 2, 3, 4);

Have constructed a bit of code that creates say 5 text fields along with corresponding submit buttons.

Have managed this with For Loops. Is there a more elegant way to do this?

I feel my code can be improved as it would be very cumbersome to keep copy-pasting and changing the relative numbers especially for the submit() function. The overall code would take up too much space.

Can the submit function reside within a for loop as well?

Would love to hear some ideas so that I can take it forward. Thanks!

Here is the code I'm using:

import controlP5.*;

ControlP5 cp5;

// Should we do an array for this initialization?
// I don't want to type out say 30 textValues. What is the more elegant way to represent this?
// Arrays.fill()??

String textValue_1 = "";
String textValue_2 = "";
String textValue_3 = "";
String textValue_4 = "";
String textValue_5 = "";

void setup() {
  size(800, 1000);
  cp5 = new ControlP5(this);

  for (int i = 1; i < 6; ++i) {
    cp5.addTextfield("textValue" + "_" + i)
      .setPosition(20, 80*i)
        .setSize(200, 40)
          .setFont(createFont("arial", 20))
            .setCaptionLabel("Enter Text for field " + i)
              .setAutoClear(false)
                ;

    cp5.addButton("submit"+ "_" + i)
      .setPosition(240, 80*i)
        .setSize(80, 40)
          .setCaptionLabel("submit")
            .getCaptionLabel().align(ControlP5.CENTER, ControlP5.CENTER)
              ;
  }
} 

void draw() {
  background(0);
}

// The function for submit... can this be done in a for loop?
// I may want a large number of text fields
// and it can get tedious typing it all out every time I change the number


public void submit_1() {
  cp5.get(Textfield.class, "textValue_1").submit();
}

public void submit_2() {
  cp5.get(Textfield.class, "textValue_2").submit();
}

public void submit_3() {
  cp5.get(Textfield.class, "textValue_3").submit();
}

public void submit_4() {
  cp5.get(Textfield.class, "textValue_4").submit();
}

public void submit_5() {
  cp5.get(Textfield.class, "textValue_5").submit();
}


void controlEvent(ControlEvent theEvent) {
  if (theEvent.isAssignableFrom(Textfield.class)) {
    println("controlEvent: accessing a string from controller '"
      +theEvent.getName()+"': "
      +theEvent.getStringValue()
      );
  }
}

void setup() {
  // if a class is an instance of creating class
   Child_1 c = new Child_1() ;

   for(int i = 0 ; i < child_class(this, "Mother").length ; i++) {
    if(c instanceof child_class(this, "Mother")[i] ) println(i, "yes") ;
   }
}

Class [] child_class(PApplet parent, String super_class_name) {
  Class[] c = parent.getClass().getDeclaredClasses();
  c = new Class[c.length -1] ;
  return c ;
}

class Mother {
  Mother() {}
}

class Child_1 extends Mother {
  Child_1 () {}
}

class Child_2 extends Mother {
  Child_2 () {}
}

Has anyone encountered or fixed this before?

Thanks

I've seen there is a Textfield lock() method but I don't know how to use it.

import controlP5.*;

ControlP5 cp5;



color ccolor=color(250, random(100), random(100));

void setup() {
  size(700,400);
  
  PFont font = createFont("arial",20);
  
  cp5 = new ControlP5(this);
  
  cp5.addTextfield("Subject number")
     .setPosition(20,170)
     .setSize(200,40)
     .setFont(createFont("arial",20))
     .setAutoClear(true)
     .setColorLabel(ccolor);
     ;
       
  cp5.addBang("OK")
     .setPosition(240,170)
     .setSize(40,40)
     .getCaptionLabel().align(ControlP5.CENTER, ControlP5.CENTER)
     ;      
     
  textFont(font);
}

void draw() {
  background(0);
  fill(255);
  
}



void controlEvent(ControlEvent theEvent) {
  if(theEvent.isAssignableFrom(Textfield.class)) {
    println("controlEvent: accessing a string from controller '"
            +theEvent.getName()+"': "
            +theEvent.getStringValue()
            );
  }
}

I have been looking through PS source code but I have not found an obvious way of doing this.

Any hints or ideas gratefully received.

Thanks
