我正在使用以下免费软件代码成功驱动步进电机：

#include <Arduino.h>
#include "BasicStepperDriver.h"

// Motor steps per revolution. Most steppers are 200 steps or 1.8 degrees/step
#define MOTOR_STEPS 200
#define RPM 120

// Since microstepping is set externally, make sure this matches the selected mode
// If it doesn't, the motor will move at a different RPM than chosen
// 1=full step, 2=half step etc.
#define MICROSTEPS 1

// All the wires needed for full functionality
#define DIR 4
#define STEP 3
//Uncomment line to use enable/disable functionality
//#define SLEEP 13

// 2-wire basic config, microstepping is hardwired on the driver
BasicStepperDriver stepper(MOTOR_STEPS, DIR, STEP);

//Uncomment line to use enable/disable functionality
//BasicStepperDriver stepper(MOTOR_STEPS, DIR, STEP, SLEEP);

void setup() {
    stepper.begin(RPM, MICROSTEPS);
    // if using enable/disable on ENABLE pin (active LOW) instead of SLEEP uncomment next line
    // stepper.setEnableActiveState(LOW);
}

void loop() {

    // energize coils - the motor will hold position
    // stepper.enable();

    /*
     * Moving motor one full revolution using the degree notation
     */
    stepper.rotate(360);

    /*
     * Moving motor to original position using steps
     */
    stepper.move(-MOTOR_STEPS*MICROSTEPS);

    // pause and allow the motor to be moved by hand
    // stepper.disable();

    delay(5000);
}

但是，我想使用相同的 Arduino-Uno 一次驱动两个电机并稍微更改代码。我能做些什么？我对编码非常陌生，所以轻松一点。我知道有一种叫做函数的东西，它接收值。但是，我需要它使用多个控制引脚：每个电机两个 - “step”（每次将电机移动一步）和“dir”（每个电机的旋转方向）。我也明白这个功能：

BasicStepperDriver stepper(MOTOR_STEPS, DIR, STEP);

一次不能接受 4 个值（DIR1、DIR2、STEP1 和 STEP2）。我希望可以使用上面的代码（稍作改动），以便使用 4 个不同的 I/O 引脚（2 个用于第一个电机驱动器（我的 arduino 连接到一个电机驱动器）一次控制 2 个电机我有 2 个并想用另一个来驱动另一个电机）“step”和“dir”引脚，2 个用于第二个电机驱动器的“step”和“dir”引脚）。

谢谢
