l298n驱动步进电机程序

下面是使用L298N驱动步进电机的示例代码，其中使用Arduino控制器：

// Define pin connections for L298N motor driver
const int stepsPerRevolution = 200; // Change this to fit the number of steps per revolution for your stepper motor
const int motorPin1 = 8;
const int motorPin2 = 9;
const int motorPin3 = 10;
const int motorPin4 = 11;

void setup()
{
  // Declare the motor pins as outputs
  pinMode(motorPin1, OUTPUT);
  pinMode(motorPin2, OUTPUT);
  pinMode(motorPin3, OUTPUT);
  pinMode(motorPin4, OUTPUT);
}

void loop()
{
  // Set the motor speed (RPMs)
  int motorSpeed = 60;
  // Set the direction of rotation
  int dir = 1;

  // Calculate the delay time for each step based on the motor speed
  int delayTime = 60 * 1000 / stepsPerRevolution / motorSpeed;

  // Turn the motor in the specified direction
  if (dir == 1) {
    for (int i = 0; i < stepsPerRevolution; i++) {
      digitalWrite(motorPin1, HIGH);
      digitalWrite(motorPin2, LOW);
      digitalWrite(motorPin3, LOW);
      digitalWrite(motorPin4, LOW);
      delay(delayTime);
      digitalWrite(motorPin1, LOW);
      digitalWrite(motorPin2, HIGH);
      digitalWrite(motorPin3, LOW);
      digitalWrite(motorPin4, LOW);
      delay(delayTime);
      digitalWrite(motorPin1, LOW);
      digitalWrite(motorPin2, LOW);
      digitalWrite(motorPin3, HIGH);
      digitalWrite(motorPin4, LOW);
      delay(delayTime);
      digitalWrite(motorPin1, LOW);
      digitalWrite(motorPin2, LOW);
      digitalWrite(motorPin3, LOW);
      digitalWrite(motorPin4, HIGH);
      delay(delayTime);
    }
  } else {
    for (int i = 0; i < stepsPerRevolution; i++) {
      digitalWrite(motorPin1, LOW);
      digitalWrite(motorPin2, LOW);
      digitalWrite(motorPin3, LOW);
      digitalWrite(motorPin4, HIGH);
      delay(delayTime);
      digitalWrite(motorPin1, LOW);
      digitalWrite(motorPin2, LOW);
      digitalWrite(motorPin3, HIGH);
      digitalWrite(motorPin4, LOW);
      delay(delayTime);
      digitalWrite(motorPin1, LOW);
      digitalWrite(motorPin2, HIGH);
      digitalWrite(motorPin3, LOW);
      digitalWrite(motorPin4, LOW);
      delay(delayTime);
      digitalWrite(motorPin1, HIGH);
      digitalWrite(motorPin2, LOW);
      digitalWrite(motorPin3, LOW);
      digitalWrite(motorPin4, LOW);
      delay(delayTime);
    }
  }
}

需要注意的是，这只是一个基本的示例代码，需要根据具体的步进电机型号和L298N模块接线情况进行修改。
