基于Arduino Uno的简易可视化操作界面设计

news2024/9/25 19:14:33

        Arduino UNO是基于ATmega328P的Arduino开发板。它有14个数字输入/输出引脚（其中6个可用于PWM输出）、6个模拟输入引脚，一个16 MHz的晶体振荡器，一个USB接口，一个DC接口，一个ICSP接口，一个复位按钮。Arduino一词意味着该款开发板可以使用Arduino官方和第三方库文件，简化开发流程，可以让我们在不了解单片机底层原理下对其进行充分开发，因此Arduino获得了众多初级开发者的喜爱。

一、总体设计

        本次项目采用模块化编程的设计方式，因为在实际设计中，我们利用状态者模式隔离不同模式下的功能操作，如下：

        程序整体设计思路来自于状态者模式，对于初学者并不友好，使用C++语言设计，参考代码如下：

#include "State.h"

//状态1，继承重写doThing
void StateCase1::doThing(CurState *s){
  //静态变量作为开关，防止重复创建对象
  static int count = 0;
  //进行开关判断，创建过就不再创建
  if(count == 0){
    s->getOled()->setLogo(new ServoP(s->getOled()));
    count = 1;                  
  }
  //按下1按键，滑动到2状态
  if(m_command == 1){
    delete s->getCase(); //回收状态管理者的此时指针
    s->setCase(new StateCase2); //new 一个新的状态，设置进去这里为2
    count = 0; //开关打开，方便下次跳转到这时创建对象
  }
  //按下1按键，滑动到3状态
  else if(m_command == 2){
    delete s->getCase(); //回收状态管理者的此时BaseCase指针
    s->setCase(new StateCase3); //new 一个新的状态，设置进去这里为3
    count = 0; //开关打开，方便下次跳转到这时创建对象
  }
  //5键为确定，跳转到状态5
  else if(m_command == 5){
    delete s->getCase(); //回收状态管理者的此时BaseCase指针
    s->setCase(new StateCase4); //new 一个新的状态，设置进去这里为3
    count = 0; //开关打开，方便下次跳转到这时创建对象 
  }
}

void StateCase2::doThing(CurState *s){
  //静态变量作为开关，放置重复创建对象
  static int count = 0;
  //进行开关判断，创建过就不再创建
  if(count == 0){
    s->getOled()->setLogo(new MusicP(s->getOled()));
    count = 1;
  }
  //按下1按键，滑动到1状态
  else if(m_command == 2){
    delete s->getCase(); //回收状态管理者的此时BaseCase指针
    s->setCase(new StateCase1); //new 一个新的状态，设置进去这里为1
    count = 0; //开关打开，方便下次跳转到这时创建对象 
  }  
  else if(m_command == 5){
    delete s->getCase(); //回收状态管理者的此时BaseCase指针
    s->setCase(new StateCase5); //new 一个新的状态，设置进去这里为5
    count = 0; //开关打开，方便下次跳转到这时创建对象 
  }
}

//以下状态剩余类推
void StateCase3::doThing(CurState *s){
  static int count = 0;
  if(count == 0){
    s->getOled()->setLogo(new ClockP(s->getOled()));
    count = 1;
  }
  if(m_command == 1){
    delete s->getCase();
    s->setCase(new StateCase1);
    count = 0;
  }
  else if(m_command == 5){
    delete s->getCase();
    s->setCase(new StateCase7);
    count = 0;
  }
}

void StateCase4::doThing(CurState *s){
  static int count = 0;
  static int angle=0;
  if(count == 0){
    s->getOled()->setLogo(new Servo_fun(s->getOled()));
    count = 1;
  }
  s->getOled()->printW(48, 32, 2, angle);
  if(m_command == 3){
    delete s->getCase();
    s->setCase(new StateCase1);
    angle = 0;
    s->getServo()->write(0);
    count = 0;
  }
  else if(m_command == 1){

    }

  }  
}

  void showLogo(void);
private:
  MyOled *m_oled;
};

//舵机图标
class Servo_fun: public LogoPicture{
public:
  Servo_fun(MyOled *oled);
  ~Servo_fun(void);
  void showLogo(void);
private:
  MyOled *m_oled;
};

//音乐播放界面
class Playlist: public LogoPicture{
public:
  Playlist(MyOled *oled);
  ~Playlist(void);
  void showLogo(void);
private:
  MyOled *m_oled;
};

//演奏中
class Playing: public LogoPicture{
public:
  Playing(MyOled *oled);
  ~Playing(void);
  void showLogo(void);
private:
  MyOled *m_oled;
};

//时钟计时界面
class ClockCount: public LogoPicture{
public:
  ClockCount(MyOled *oled);
  ~ClockCount(void);
  void showLogo(void);
private:
  MyOled *m_oled;
};

二、功能演示

        程序运行，我们可以看到图形化界面如下，可按上下进行功能切换：

      点击进入音乐界面，按上下按键可以调节舵机旋转角度，并且舵机跟着转动，如图：

        点击英语界面，选择第一个音乐，蜂鸣器鸣叫模拟音乐

        点击进入时钟界面，此时可以进行计时操作，如下：

三、设计总结

        本次设计使用Arduino IDE开发Arduino UNO，利用oled模块显示可视化界面，对应操作不同器件了，本次设计利用状态者模式进行设计，为程序的可扩展性提供了很大便利。
