Arduino头文件“没有匹配的调用功能”

Question

I've been working on an Arduino project. Until recently I had everything in located in the one .ino file. I have decided to restructure my code and move my classes to their own files.

My problem is when I copy my Sensor class to a .h file, and include it, my program is unable to compile, and I get the following error.

If I copy it back to the .ino file, then everything works perfectly again.

My Sensor class

class Sensor {
public:
    Sensor(byte sensorType, byte sensorID) : _sensorType(sensorType), _sensorID(sensorID) {}

    virtual ~Sensor() {}

    virtual unsigned int getReading() = 0;

    byte sensorID() { return _sensorID; }
    byte sensorType() { return _sensorType; }

private:
    byte _sensorType;
    byte _sensorID;
};

Thank you

在您的外部代码文件中#include <Arduino.h> 。
