Question

我为下面的问题找了一个月的答案，但是我找不到它，所以这里有我的问题：我为Arduino编写了一个库，以下是我的代码，编译器总是显示

error: 'iniziaScheda1' was not declared in this scope

和其他功能相同的错误，我该怎么办？

CNC.h

#ifndef CNC
#define CNC

#include <Arduino.h>

        int  clockPin2;
        int  dataPin2;
        byte scheda[7]; 
        int count;

#include <CNC.h>


void setup() {
 iniziaScheda1(1,2,3);// put your setup code here, to run once:
velocita=20;
}

void loop() {
  motoreZ(50);
  delay(1000);
  motoreZ(-50);
  delay(1000);// put your main code here, to run repeatedly:

}

Answer 1

您的函数是类成员，因此您应该创建类实例，然后在其上调用成员，即：。

CNCa tmp;
tmp.iniziaScheda1(1,2,3);

要保留类成员变量的值，您的类实例应具有全局范围。

错误：＆＃39; iniziaScheda1＆＃39;在这方面没有申明
