how to show multiple data from arduino

Fiansyah

how to read the value from arduino and then i want to displaying that on processing window. This is my arduino code:

      #include <TimerOne.h>            
      #include <PZEM004T.h>
      #include <LiquidCrystal.h>


      int dutycycle = 0;     // Initailize duty cylce variable as integer data type
      int incomingByte = 0;
      PZEM004T pzem(2,3);  // (RX,TX) connect to TX,RX of PZEM
      IPAddress ip(192,168,1,1);
      LiquidCrystal lcd(12, 11, 4, 5, 6, 7);


       void setup()               // Setup function
      {
        Serial.begin(9600);
        pinMode (9, OUTPUT);             // set pin 9 as an output pin for pwm
        pinMode (10, OUTPUT);            // set pin 10 as an output pin for pwm
        Timer1.initialize(20000);             // Initailize timer1 time period as 20 milli second (50 Hz frequency)
        TCCR1A = (TCCR1A & 0x0F) | 0xB0 ;             // set pin 10 inverted of pin 9
        pzem.setAddress(ip);
        lcd.begin(16, 2); // lcd rows and columns
       }


      void loop()              // loop function starts
      { 
      if (Serial.available() > 0)
      {
      incomingByte = Serial.read ();  
      dutycycle = map(incomingByte, 0, 255, 0, 1023);
      Timer1.pwm(9, dutycycle, 20000);            // Timer1.pwm function takes argument as (pin no. , dutycycle , time period)
      Timer1.pwm(10, 1023-dutycycle, 20000);


      float v = pzem.voltage(ip);
      if (v < 0.0) v = 0.0;

      Serial.print(v);Serial.print("V; ");
      lcd.clear();
      lcd.setCursor(0,0);
      lcd.print("V= ");
      lcd.setCursor(2,0);
      lcd.print(v);


      float i = pzem.current(ip);
      if (i < 0.0) i = 0.0;

      Serial.print(i);Serial.print("A; ");
      lcd.clear();
      lcd.setCursor(9,0);
      lcd.print("A= ");
      lcd.setCursor(11,0);
      lcd.print(i);


      float p = pzem.power(ip);
      if (p < 0.0) p = 0.0;

      Serial.print(p);Serial.print("W; ");
      lcd.clear();
      lcd.setCursor(9,1);
      lcd.print("W= ");
      lcd.setCursor(11,1);
      lcd.print(p);


      float e = pzem.energy(ip);

      Serial.print("PF= ");Serial.print((p)/(v*i));
      lcd.setCursor(0,1);
      lcd.print("PF=");
      lcd.setCursor(3,1);
      lcd.print((p)/(v*i));

      Serial.println(v);
      Serial.println(i);
      Serial.println(p);
      Serial.println((p)/(v*i));

     delay(100);  
     }
     }               // loop function ends

i want to send the value of "v","i","p" and "pf" and show it in processing window, this is my processing code :

      import controlP5.*;
      import processing.serial.*;

      ControlP5 cP5;

      Serial arduino;
      String val= "0";

      void setup() 
      {
      size(800, 550);
      println(Serial.list());
      String portName = Serial.list()[0];
      arduino = new Serial(this, portName, 9600);

      cP5 = new ControlP5(this);
      cP5.addSlider("ATUR DUTY CYCLE", 0, 255, 0, 210, 155, 350, 50);
      }

      void draw() 
      {
      background(#614DED);
      textSize(20);
      fill(#F5ED00);
      text("PENGENDALIAN INVERTER FULL BRIDGE SATU FASA", 140, 30);
      textSize(20);
      text("SECARA WIRELESS BERBASIS ARDUINO", 200,60);
      text("ARUS", 210, 300);
      text("TEGANGAN", 460, 300);
      text("DAYA", 210, 400);
      text("FAKTOR DAYA", 460, 400);

      if (arduino.available() >0){
      delay(100);
      val=arduino.readString();}  

      textSize(18);
      fill(#FAFF08);
      text(val, 210 ,330 );

      textSize(18);
      fill(#FAFF08);
      text(val, 460, 330);

      textSize(18);
      fill(#FAFF08);
      text(val, 210, 430);

      textSize(18);
      fill(#FAFF08);
      text(val, 460, 430);

      }

       void controlEvent(ControlEvent theEvent) {
       if(theEvent.isController()) {

       int val = int(theEvent.getController().getValue());
       arduino.write(val);
       } 
       }

Thank you very much

There is a new forum- see processing main page

kfrajer

You can see a demo at the end of this post:

https://forum.processing.org/two/discussion/comment/88886#Comment_88886

The ino and processing code are in two separate posts. You should be able to identify them if you follow the chat there. any other questions, in the new forum. Don't forget to cross-link your new post with this one.
