three sliders to control three servomotors with ControlP5

lkmao2001

Hi,

I am trying to use 3 different servos with 3 sliders using ControlP5.
The sketch should know which slider (servo) it is and which direction (open or closed) since I need to send that information to Arduino.
So far, processing just displays the values within saying which slider (servo) has moved. Would it be possible to assign a character for each slider? Then, Arduino would check the first character to see which servo it is moving and which direction, e.g., V1--V servo going clockwise, or A-1--A servo going counter-clockwise.

If someone could give me a hint, that would be greatly appreciated.

Thanks.

I don't get what you are asking. but I interpret it as you want to send the data to arduino.. you use .write to send data..

import processing.serial.*;   // Import processing serial library
import controlP5.*;           // Import controlP5 library
Serial serial;                // Create serial object
ControlP5 cp5;                // Create ControlP5 object
int delay=0;

void setup() 
{
  size(720,480);              // Size of window
  smooth();                   // Anti-aliased edges
  cp5 = new ControlP5(this);  // Create new cp5 object
  PFont font = createFont("ArialMT",20);

  // Open whatever port is the one you're using.
  String portName = Serial.list()[0];
  serial = new Serial(this, portName, 9600);

  cp5.addSlider("V")
     .setLabel("V Valve")
     .setPosition(100,100)
     .setWidth(200)
     .setHeight(20)
     .setRange(-1,1)
     .setValue(0)
     .setNumberOfTickMarks(3)
     .setSliderMode(Slider.FLEXIBLE)
     ;

   cp5.addSlider("A")
      .setLabel("A Valve")
     .setPosition(100,200)
     .setWidth(200)
     .setHeight(20)
     .setRange(-1,1)
     .setValue(0)
     .setNumberOfTickMarks(3)
     .setSliderMode(Slider.FLEXIBLE)
     ;

   cp5.addSlider("D")
     .setLabel("D Valve")
     .setPosition(100,300)
     .setWidth(200)
     .setHeight(20)
     .setRange(-1,1)
     .setValue(0)
     .setNumberOfTickMarks(3)
     .setSliderMode(Slider.FLEXIBLE)
     ;

  // Set texts for controlling servomotors   
  cp5.addTextfield("Closed")
     .setPosition(100,350)
     .setSize(100,1)
     .setFont(font)
     .setFocus(true)
     .setColor(color(255,0,0))
     .setAutoClear(false)
     ;

     .setPosition(192,350)

     ; 
}

void draw()
{
  background(0);                // Set background color to black
}

void controlEvent(ControlEvent c)
{

//delay timer because for some reason it runs controleEvent 4 times. when u press somthing..
  if(millis() > delay){ 
    delay=millis()+100;
    println(c.getValue());       // Display value of sliders and toggle
    println(c.getController().getName());  // Display name of slider.
//sends to arduino. the string that is sent is somthing like "A1.0" if i used A and set it to 1..
    serial.write(c.getController().getName()+c.getValue()+"\r");
}

and for the arduino it would be somthing like. but i dont have an arduino so cant rly test anything, but i dont see why it would not work.

String strCompare1 = "A0.0";
String strCompare2 = "A-1.0";
String strCompare3 = "A1.0";
String strCompare4 = "V0.0";
char inByte;
String strInput = "";

void setup(){
 Serial.begin(9600);
}


void loop(){



 while (Serial.available() > 0)
 {
  // get incoming byte:
  inByte = Serial.read();
  if (inByte == '\r'){
   //compare input message
   if(strInput.equals(strCompare1)){
    //If A 0 do stuff
   }
   if(strInput.equals(strCompare2)){
    //If A -1 do stuff
   }
   if(strInput.equals(strCompare3)){
    //If A 1 do stuff
   }
   if(strInput.equals(strCompare4)){
    //If V 0 do stuff
   }


   //reset strInput
   strInput = "";
  }
  else
  {
  strInput += inByte;
  }
 } 


}
