如何修复我为 Arduino 制作的步进电机库？

Question

我有一个 Arduino Mega，我正在使用 L298N，我的目标是制作一个成功的 Arduino 库，以使用步进电机制作音乐。我知道以前已经采用过这种方法，但我正在尝试自己做。我不能使用 Moppy 库，坦率地说，其他人的代码非常复杂。那么，我的问题是什么？我的问题是当我使用我制作的库（作为测试）时出现此错误：

      ^~~~~~~~~~

还有这个：

exit status 1
Error compiling for board Arduino Mega or Mega 2560.

我希望库能够运行顺利，因为我正在关注其他一些步进电机库，但我遇到了这些错误。我试过多次修改代码，但我遇到了类似的问题，所以我不确定如何解决我自己的问题。我什至尝试过复制和粘贴一些代码来使库正常工作。没有什么。我正在使用其他人制作的 Arduino 步进器、Accelstepper 和双极步进器库，但没有结果。 https://create.arduino.cc/projecthub/ambhatt/bipolar-stepper-motor-library-b9d5e0

这是 .h 文件：

// determine direction based on whether steps_to_mode is + or -:
  if (frequency > 0) { direction = 1; }
  if (frequency < 0) { direction = 0; }

    digitalWrite(SMPin1, HIGH);
    digitalWrite(SMPin2, LOW);
    digitalWrite(SMPin3, HIGH);
    digitalWrite(SMPin4, LOW);

    delay(1);

    delay(duration);

}

这是keywords.txt:

stepperTest KEYWORD1
runStepper  KEYWORD2

这是 .ino 示例：

#include <stepperTestLibrary.h>

stepperTest myStepper(22, 23, 24, 25);


void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

myStepper.runStepper(440, 500);

}

接线如下：

这是步进器数据表的 link：

阅读一些关于类 in C++ 的内容将是一个好的开始。也许变量名是如何工作的。以及阴影变量如何工作。 SMPin2、_SMPin2 和第三个变体是 intSMPin2 之间有很大区别（其他变体也搞砸了）

无论如何，如果你想在构造函数中使用与成员相同的参数名称，你必须使用构造函数初始化列表。

#ifndef stepperTestLibrary_h
#define stepperTestLibrary_h

#include "Arduino.h"

class stepperTest {
public:
  stepperTest(uint8_t SMPin1, uint8_t SMPin2, uint8_t SMPin3, uint8_t SMPin4);

  void runStepper(int frequency, int duration);

private: 
  // just give some space to it:
  uint8_t SMPin1;
  uint8_t SMPin2;
  uint8_t SMPin3;
  uint8_t SMPin4;

  int8_t direction;

  /// or you'll mess it up like this:
  ///  int SMPin1, --->>>>>  intSMPin2, intSMPin3, intSMPin4  <<<<<---;
};

#endif

主要部分：

#include "Arduino.h"
#include "stepperTestLibrary.h"

stepperTest::stepperTest(uint8_t SMPin1, uint8_t SMPin2, uint8_t SMPin3, uint8_t SMPin4)
// constructor's initializer list:
: SMPin1{ SMPin1 }
, SMPin2{ SMPin2 }
, SMPin3{ SMPin3 }
, SMPin4{ SMPin4 }
, direction{ 0 }
{
    pinMode(SMPin1, OUTPUT);
    pinMode(SMPin2, OUTPUT);
    pinMode(SMPin3, OUTPUT);
    pinMode(SMPin4, OUTPUT);
}

void stepperTest::runStepper(int frequency, int duration) {

    // // Never used anywhere:  
    // int rpmCalculation = abs(1000.0 / frequency); 
    // // determine direction based on whether steps_to_mode is + or -:
    // if (frequency > 0) { direction = 1; }
    // if (frequency < 0) { direction = 0; }

    digitalWrite(SMPin1, HIGH);
    digitalWrite(SMPin2, LOW);
    digitalWrite(SMPin3, HIGH);
    digitalWrite(SMPin4, LOW);

    delay(1);

    digitalWrite(SMPin1, LOW);
    digitalWrite(SMPin2, HIGH);
    digitalWrite(SMPin3, HIGH);
    digitalWrite(SMPin4, LOW);

    delay(1);

    digitalWrite(SMPin1, LOW);
    digitalWrite(SMPin2, HIGH);
    digitalWrite(SMPin3, LOW);
    digitalWrite(SMPin4, HIGH);

    delay(1);

    digitalWrite(SMPin1, HIGH);
    digitalWrite(SMPin2, LOW);
    digitalWrite(SMPin3, LOW);
    digitalWrite(SMPin4, HIGH);

    delay(duration); // what? why???
}
