我正在使用 Processing 和 controlp5 为带有一些传感器的 Arduino 构建一个接口。我想要有很多传感器，所以我试图以模块化方式构建接口，这样我就可以实例化与传感器一样多的控制面板，并在我的硬件发送遥测数据包时立即更新所有面板。

我已经做了一些工作并绘制小部件，但似乎我的回调函数没有被触发 - 例如，当按下下面代码中的按钮之一时，相应的串行打印输出不会发生。此外，println(channelOne.currentGain);无论增益滑块在做什么，主草图中的总是打印 0。

我没有做太多Java，所以我确信我在这里遗漏了一些关于如何声明类及其变量的基本内容，任何关于如何正确设置它的指针将不胜感激！

这是我的主要程序：

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);
}

这是 SensorChannel 的类定义：

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)
    ;

  }

  void triggered(boolean theFlag)
  {
    println("Trigger status: " + theFlag);
  }

  void manualOverride(boolean theFlag)
  {
    println("Manual Override status: " + theFlag);
  }

  void calibrateBaseline(boolean theFlag)
  {
    println("Calibrate Baseline status: " + theFlag);
  }

  void calibrateGain(boolean theFlag)
  {
    println("Calibrate Gain status: " + theFlag);
  }

  void calibrateTrigger(boolean theFlag)
  {
    println("Calibrate Trigger status: " + theFlag);
  }

  void selfControl(boolean theFlag)
  {
    println("Self Control status: " + theFlag);
  }

可以改进的地方很少：

  • 无需打电话delay()。draw()每秒被调用大约 60 次，但您可以使用frameRate()轻松（并且干净地）控制（例如framerate(50);）
  • 您正在 SensorChannel 中实例化 cp5。也许您可以在主草图中创建单个 ControlP5 实例并传递对 SensorChannel 的引用（将实例重新用于多个未来通道）

有多种方法可以挖掘价值。您应该查看示例 > 贡献库 > ControlP5 > 使用

一种应该直截了当的方法是使用 Controller 的plugTo()方法。您传递一个对象来插入控制器，只要该对象具有与控制器同名的属性，它就会设置它的值：

import controlP5.*;

SensorChannel channelOne;
ControlP5 cp5;

void setup()
{
  size(800, 450);
  smooth();
  cp5 = new ControlP5(this);
  channelOne = new SensorChannel(this,cp5, 30, 30);
}

void draw()
{
  background(0);

  text("currentGain:"+channelOne.currentGain,10,15);
}

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, ControlP5 cp5,int x, int y)
  {

    app = papp;
    this.cp5 = cp5;

    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)
    .plugTo(this)
    ;
    //Gain setting (1 byte)
    cp5.addSlider("currentGain")
    .setLabel("Gain")
    .setPosition(x+0,y+263)
    .setSize(306,20)
    .setRange(0,255)
    .plugTo(this);
    ;

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

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

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

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

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

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

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

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

  }

}

这是一个建议。随意探索有关控制器事件和值的其他 ControlP5 示例。
