下午好，我正在使用stm32蓝丸usb接口，开发环境“iar”。问题是，当我通过应用程序连接时，箭头后面的数字“3”并没有变为数字“50”，而是相反的显示在下面！见图1.2。我是按照协议工作的。
你如何做到这一点？我正在使用controlp5库和cp5.addnumberbox。


“iar”中的数据。

int Bullet = 50;  // variable for result
sprintf((char *)str, "(,%d,-Ђ",Bullet);  // sending a command with data to stm32.

在displaydata选项卡的代码中，行“case 40”是符号（该命令也可以使用虚拟com端口通过终端发送）。命令：（，50，！图3。

我得把整个小项目布置好让你看看。
通信接口1：

import processing.serial.*; 
import controlP5.*;
ControlP5 cp5;
DropdownList serialPortsList;

Serial serialPort;
final int BAUD_RATE = 9600;

char parity = 'N';
int dataBits = 8;
float stopBits = 1.0;

public void setup() {
  background(50);
  size(700, 420, P3D);
  surface.setTitle("TEST");
  surface.setResizable(false);
  setupUI();
  smooth();
  frameRate(30);
  writeOutgioing[lengthmas-1]=1; 
  String[] portNames = Serial.list();
  //serialPort.clear(); // Why does not it work?
  for (int i = 0; i < portNames.length; i++) serialPortsList.addItem(portNames[i], i);
}
public void toplug (int theValue) 
{ // Start button on click sends a commad 1.
  println("Button click events: "+theValue);
  strata =!strata;
  if (!strata) {
    connection.setLabel("Пуск");
    serialPort.dispose();
    Vin.setText("Voltage K.V - ");
    inputPULI.setLabel("Bullet");
  } else {
    connection.setLabel("СТОП");
    serialports((int)serialPortsList.getValue());
    writeOutgioing[0]=1;
    writeOut();
  }
}
public void serialports(int theValue) {
  try {
    serialPort = new Serial(this, Serial.list()[theValue], BAUD_RATE, parity, dataBits, stopBits);
    serialPort.bufferUntil('\n');

    println("COM connected: "+ Serial.list()[theValue] );
    /*Send.unlock();
     connection.unlock();*/    // locking buttons in applications if not connected via rs-232.
  }
  catch(Exception e) {
    System.err.println("Error opening serial port" + Serial.list()[theValue]);
    e.printStackTrace();
  }
}
/*void controlEvent(ControlEvent event){
 println(event.getController().getName(),"changed value to",event.getValue(),"inputPULI = ",PUL,"inputNapryzenieKV = ",NapryzenieKV,"CheckBoxuvum= ",
 UV/UM,"P4 = ",std2,);
 }*/

显示数据：

void Displaydata() {

  switch(x)
  {
  case 20:
    // What to write?
    // label(testRead[1]+" Мин."); // ImageButton
    // min=testRead[1];
    break;
  case 30:
    // What to write?
    // P4.setText("std2"+ testRead[1]); // CheckBox
    break;
  case 40:
    inputPULI.setLabel("Bullet: " + testRead[1] );
    break;
  case 70:
    inputNapryzenieKV.setLabel("Voltage: " + testRead[1] );
    break;
  case 60:
    Vin.setText("Voltage K.V: " + testRead[1] + " " + testRead[2]);
    break;
  case 50:
    // What to write?
    //CheckBoxuvum.setText("UV/UM - " +testRead[1] ); // RadioButton
    break;
  default:
    println("DisplayData(): no case selected.");
    break; // technically not necessary, but I like my switches tidy
  }
}

协议：

int lengthmas = 7;
int RC = 0x21; // -128 separating byte в java
int[] writeOutgioing = new int[lengthmas];
String incomingData= null;
String outgoingData=null;
String[] testRead = new String[lengthmas];
int x;

void readInc() {
  while ( serialPort.available() > 0) 
  {
    incomingData = serialPort.readStringUntil(RC);
    testRead = split (incomingData, ',' );
    if (testRead != null)
    {
      x = (int) testRead[0].charAt(0);
      Displaydata();
    }
  }
}

void  writeOut() {
  outgoingData=str(writeOutgioing[0])+str(writeOutgioing[1])+str(writeOutgioing[2])+str(writeOutgioing[3])+str(writeOutgioing[4])+str(writeOutgioing[5])+str(writeOutgioing[6]); // sending data as a string.
  serialPort.write(outgoingData);
}

发送数据：

public void toapply()
{
}

回路：

void draw() 
{

  background(50);
  button.draw();

  if (strata) 
  {
    readInc();
  }
}

代码：

inputPULI = cp5.addNumberbox("PUL")
    .setLabel("Bullet")
    .setPosition(220, 220)
    .setSize(80, 30)
    .setColorValue(0xffffff00)
    .setFont(p)
    .setScrollSensitivity(1.1)
    .setDirection(Controller.HORIZONTAL)
    .setRange(1, 199)
    .setValue(3);
  Label labelinputPULI = inputPULI.getCaptionLabel();
  labelinputPULI.setFont(font);
  labelinputPULI.setColor(color(#00ffff));
  labelinputPULI.toUpperCase(false);
  labelinputPULI.setText("Bullet");
  labelinputPULI.align(ControlP5.LEFT_OUTSIDE, CENTER);
  labelinputPULI.getStyle().setPaddingLeft(-25);
