Arduino - C++对象构造函数错误

Arduino - C++ Object Constructor Error

本文关键字:构造函数 错误 对象 C++ Arduino      更新时间:2023-10-16

我正在尝试调试我的一些arduino代码,并不断收到与对象构造函数相关的错误。我相信我已经正确定义了所有内容并提供正确的输入,但我仍然无法获得要编译的代码。

我粘贴了下面的错误和代码。请注意,我已经删除了"数据控制"类中的一些源代码。另请注意,CDOS_Info是我创建的结构。

感谢您的任何帮助!

错误:

数据控制标头:

#ifndef DataControl_h
#define DataControl_h
#include "CDOS_Definitions.h"
class DataControl
{
    public:
        DataControl(CDOS_Info *inputtedInfo);

};
#endif

数据控制源代码:

#include "Arduino.h"
#include "DataControl.h"
#include "CDOS_Definitions.h"
#include "SensorSerialInterface.h"

DataControl::DataControl(CDOS_Info *inputtedInfo)
{   
    info = inputtedInfo;    
}

如果不调用对象的构造函数,则无法创建对象。因为StateController也是一个DataControl,你不能在不调用DataControl的构造函数(以及StateController(的情况下创建一个。但是该构造函数接受一个参数,因此编译器无法为您添加调用。

调用基类构造函数的

方法是修改派生类的构造函数,如下所示:

StateController::StateController(CDOS_Info *inputtedInfo)
    : DataControl(inputtedInfo) // calls DataControl's constructor
{
   // info = inputtedInfo; // Don't need this, because DataControl's constructor does it.
   userInput = InputInterface();
   dataControl = DataControl(info);
   lightController = LEDController();
}

注意奇怪的语法 - 这不是一个正常的函数调用。是的,它确实超出了大括号。
