Question

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。我能做什么？我是编码的新手，所以轻松一点。我了解有一种叫做函数的函数，它可以接收值。但是，我需要它使用多个控制销：每个电动机两个控制销-“步进”（每次使电动机进一步移动一步）和“ dir”（每个电动机的旋转方向）。我也了解该功能：

BasicStepperDriver stepper(MOTOR_STEPS, DIR, STEP);

一次不能接受4个值（DIR1，DIR2，STEP1和STEP2）。我想使用上面的代码（稍作更改），以便一次使用4个不同的I / O引脚控制2个电动机（第一个电动机驱动器2个（我的arduino连接到电动机驱动器，我有2个驱动器，并且想用另一个驱动另一个电机）“ step”和“ dir”引脚，而2个是第二个电机驱动器的“ step”和“ dir”引脚）。

感谢

我做了以下工作，而且有效！

用单个电机控制Arduino（Uno）库控制两个步进电机
