Controlling stepper motors via serial monitor - AccelStepper library

Projects Programming
5

Thanks again for the help, in its current state, each time I send an 'a' or a 'b', it moves the respective stepper motor by one step. Although, as you can probably tell from the code, I am trying to get them to do full rotations not just single steps.

I am guessing the issue is due to the stepper1.run() and stepper2.run() being inside an IF statement, so only incrementing by a single step each time. I am unsure of how to rectify this though, how can I take them out of the IF and still keep the check in place?

#include <AccelStepper.h>

AccelStepper stepper1(AccelStepper::FULL4WIRE, 5, 6, 7, 8);
AccelStepper stepper2(AccelStepper::FULL4WIRE, 9, 10, 11, 12);

void setup()
{  
    Serial.begin(9600);
    
    stepper1.setMaxSpeed(200.0);
    stepper1.setAcceleration(100.0);
    stepper1.moveTo(360);
    
    stepper2.setMaxSpeed(200.0);
    stepper2.setAcceleration(100.0);
    stepper2.moveTo(360);
}
   
    char inBuffer = "";

void loop()
{
    if(Serial.available()>0)
    {
      inBuffer = Serial.read();
    }
    
    //byte incomingByte = Serial.read();
       
    if (inBuffer == 'a')
    {
      Serial.println("test point 1");
      if (stepper1.distanceToGo() == 0)
      stepper1.moveTo(-stepper1.currentPosition());
      stepper1.run();
    }
    
    else if (inBuffer == 'b')
    {
       Serial.println("test point 2");      
       if (stepper2.distanceToGo() == 0)
       stepper2.moveTo(-stepper2.currentPosition());
       stepper2.run();
    }
    
    inBuffer = "";
}
