我如何修复我为Arduino制作的步进电机库?

Question

我有一个Arduino Mega，我使用的是L298N，我的目标是制作一个成功的Arduino库，用步进电机制作音乐。我知道这种方法以前已经有过了，但我正试图自己去做。我不会使用Moppy库，而且坦率地说，其他人的代码相当复杂。那么，我的问题是什么?我的问题是，当我使用我所做的库(作为测试)时，我得到这个错误:

和这个

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

我希望库能够顺利运行，因为我正在遵循其他一些步进电机库，但我得到了这些错误。我试过几次修改代码，但我得到了类似的问题，所以我不确定如何解决我自己的问题。我甚至尝试过复制和粘贴一些代码来使库工作。什么都没有。我正在使用Arduino步进器，Accelstepper和其他人制作的双极步进器库，没有结果。https://create.arduino.cc/projecthub/ambhatt/bipolar-stepper-motor-library-b9d5e0

}

这是keyword .txt:

stepperTest KEYWORD1
runStepper  KEYWORD2

这是。ino的例子:

#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);
}

线路如下:

阅读c++中的类将是一个很好的开始。也许还有变量名的工作原理。以及隐藏变量是如何工作的。SMPin2， _SMPin2和第三个变体intSMPin2之间有很大的区别(其他的也搞砸了)

无论如何，如果你想在构造函数中使用与成员相同的形参名，你必须使用构造函数的初始化列表。

#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

和主体部分:

#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???
}
