初探Arduino，（步进电机MP28GA+ULN2003）Setpper扩展库的使用

zzc2

刚起步，新手一枚，有错请指正啊。

Arduino uno 今天刚到，迫不及待的插上原来51用的步进电机试一下。。
不过。。貌似直接调用Setpper库无效...
无奈看头文件...
[mw_shl_code=c,true]   switch (thisStep) {
      case 0:    // 1010
      digitalWrite(motor_pin_1, HIGH);
      digitalWrite(motor_pin_2, LOW);
      digitalWrite(motor_pin_3, HIGH);
      digitalWrite(motor_pin_4, LOW);
      break;
      case 1:    // 0110
      digitalWrite(motor_pin_1, LOW);
      digitalWrite(motor_pin_2, HIGH);
      digitalWrite(motor_pin_3, HIGH);
      digitalWrite(motor_pin_4, LOW);
      break;
      case 2:    //0101
      digitalWrite(motor_pin_1, LOW);
      digitalWrite(motor_pin_2, HIGH);
      digitalWrite(motor_pin_3, LOW);
      digitalWrite(motor_pin_4, HIGH);
      break;
      case 3:    //1001
      digitalWrite(motor_pin_1, HIGH);
      digitalWrite(motor_pin_2, LOW);
      digitalWrite(motor_pin_3, LOW);
      digitalWrite(motor_pin_4, HIGH);
      break;[/mw_shl_code]

改为

[mw_shl_code=c,true]case 0:
     digitalWrite(motor_pin_1, HIGH);  
     digitalWrite(motor_pin_2, LOW);
     digitalWrite(motor_pin_3, LOW);
     digitalWrite(motor_pin_4, HIGH);
        break;
case 1:
     digitalWrite(motor_pin_1, HIGH);  
     digitalWrite(motor_pin_2, LOW);
     digitalWrite(motor_pin_3, LOW);
     digitalWrite(motor_pin_4, LOW);
        break;  
        case 2:
     digitalWrite(motor_pin_1, HIGH);  
     digitalWrite(motor_pin_2, HIGH);
     digitalWrite(motor_pin_3, LOW);
     digitalWrite(motor_pin_4, LOW);
        break;  
case 3:
     digitalWrite(motor_pin_1, LOW);  
     digitalWrite(motor_pin_2, HIGH);
     digitalWrite(motor_pin_3, LOW);
     digitalWrite(motor_pin_4, LOW);
        break;
case 4:
     digitalWrite(motor_pin_1, LOW);  
     digitalWrite(motor_pin_2, HIGH);
     digitalWrite(motor_pin_3, HIGH);
     digitalWrite(motor_pin_4, LOW);
        break;  
case 5:
     digitalWrite(motor_pin_1, LOW);  
     digitalWrite(motor_pin_2, LOW);
     digitalWrite(motor_pin_3, HIGH);
     digitalWrite(motor_pin_4, LOW);
        break;   
case 6:
     digitalWrite(motor_pin_1, LOW);  
     digitalWrite(motor_pin_2, LOW);
     digitalWrite(motor_pin_3, HIGH);
     digitalWrite(motor_pin_4, HIGH);
        break;  
case 7:
     digitalWrite(motor_pin_1, LOW);  
     digitalWrite(motor_pin_2, LOW);
     digitalWrite(motor_pin_3, LOW);
     digitalWrite(motor_pin_4, HIGH);
        break;  
default:
     digitalWrite(motor_pin_1, LOW);  
     digitalWrite(motor_pin_2, LOW);
     digitalWrite(motor_pin_3, LOW);
     digitalWrite(motor_pin_4, LOW);
   break; [/mw_shl_code]
[mw_shl_code=c,true]stepMotor(this->step_number % 7);[/mw_shl_code]

之后就正常了

测试代码
[mw_shl_code=c,true]#include <Stepper.h>
#define STEPS 300
Stepper s(STEPS,8,9,10,11);
//////////////////////////////////////////////////////////////////////////////
void setup() {
s.setSpeed(100);
}

//////////////////////////////////////////////////////////////////////////////
void loop(){
  s.step(50);
}[/mw_shl_code]
