Control P5 inside a class?

405nm

Hello,

I'm building an interface using controlp5 for an Arduino with some sensors attached to it. I want to have many sensors, so I am trying to build the interface in a modular fashion so that I can just instantiate as many control panels as I have sensors, and update all the panels at once when my hardware sends a telemetry packet.

I have made something that kind of works and draws the widgets, but it appears that my callback functions are not being triggered - for example, when one of the buttons in the code below is pressed, the corresponding serial printout does not happen. Also, the println(channelOne.currentGain); in the main sketch always prints 0, no matter what the gain slider is doing.

I don't do much Java, so I am sure that I am missing something basic here about how the class and its variables are declared, any pointers on how to set this up correctly would be much appreciated!

Here is my main program:

import processing.core.PApplet;

SensorChannel channelOne;

void setup()
{
  size(800, 450);
  smooth();

  channelOne = new SensorChannel(this, 30, 30);
}

void draw()
{
  background(0);

  println(channelOne.currentGain);
  delay(20);
}

And here is the class definition for a SensorChannel:

import processing.core.PApplet;
import controlP5.*;

class SensorChannel {
  PApplet app;
  ControlP5 cp5;

  //Moving line graph
  Chart chart;

  //CheckBox buttons;
  boolean triggered;
  boolean manualOverride;
  boolean calibrateBaseline;
  boolean calibrateGain;
  boolean calibrateTrigger;
  boolean selfControl;

  //Sliders
  int currentGain;
  int currentBalance;
  int currentReading;
  int currentTrigger;

  SensorChannel(PApplet papp, int x, int y)
  {

    app = papp;
    cp5 = new ControlP5(papp);

    println("hello!");

    //Line graph
    chart = cp5.addChart("sensorChart")
    .setPosition(x+0, y+0)
    .setSize(306, 220)
    .setRange(0, 1024)
    .setView(Chart.LINE) // use Chart.LINE, Chart.PIE, Chart.AREA, Chart.BAR_CENTERED
    .setStrokeWeight(1.5)
    .setColorCaptionLabel(color(40))
    ;

    chart.addDataSet("sensorReading");
    chart.setData("sensorReading", new float[100]);
    chart.setColors("sensorReading", color(240));

    chart.addDataSet("sensorReading");
    chart.setData("sensorReading", new float[100]);
    chart.setColors("sensorReading", color(140));

    //Reading (10bits)
    //Trigger point (10bits)

    //Balancing digipot setting (1 byte)
    cp5.addSlider("currentBalance")
    .setLabel("Balance Pot")
    .setPosition(x+0,y+284)
    .setSize(306,20)
    .setRange(0,255)
    ;
    //Gain setting (1 byte)
    cp5.addSlider("currentGain")
    .setLabel("Gain")
    .setPosition(x+0,y+263)
    .setSize(306,20)
    .setRange(0,255)
    ;

    //Current Sensor Reading (1 byte)
    cp5.addSlider("currentReading")
    .setLabel("Sensor Reading")
    .setPosition(x+0,y+221)
    .setSize(306,20)
    .setRange(0,255)
    ;

    //Trigger Point (1 byte)
    cp5.addSlider("currentTrigger")
    .setLabel("Trigger Point")
    .setPosition(x+0,y+242)
    .setSize(306,20)
    .setRange(0,255)
    ;

    //Misc. Settings Toggles
    cp5.addToggle("triggered")
    .setLabel("Trigger")
    .setPosition(x+0,y+305)
    .setSize(50,20)
    ;

    cp5.addToggle("manualOverride")
    .setLabel("Override")
    .setPosition(x+51,y+305)
    .setSize(50,20)
    ;

    cp5.addToggle("calibrateBaseline")
    .setLabel("C. Baseline")
    .setPosition(x+102,y+305)
    .setSize(50,20)
    ;

    cp5.addToggle("calibrateGain")
    .setLabel("C. Gain")
    .setPosition(x+153,y+305)
    .setSize(50,20)
    ;

    cp5.addToggle("calibrateTrigger")
    .setLabel("C. Trig")
    .setPosition(x+204,y+305)
    .setSize(50,20)
    ;

    cp5.addToggle("selfControl")
    .setLabel("S. Control")
    .setPosition(x+255,y+305)
    .setSize(50,20)
    ;
