Little Step-U

An Arduino Library for the Little Step-U Stepper Motor Controllers

Example

 #include <LittleStepU.h>
 #include <NewSoftSerial.h>
 
 #define SPEED 400
 
 //create a new LittleUStep class
 //rxPin = 2, txPin = 3, busyPin = 4
 LittleStepU uStep(2, 3, 4);
 LittleStepU uStep2(5, 6, 7); 
 
 void setup() 
 {
   
   delay(100);
   uStep.SetSpeed(SPEED);
   uStep2.SetSpeed(SPEED);
   uStep.GoToRelativePosition(8000);
   uStep2.GoToRelativePosition(7000);
   uStep.SetSpeed(SPEED);
   uStep2.SetSpeed(SPEED);
   uStep.SetHomePosition();
   uStep2.SetHomePosition();
   uStep.SetOffStatePower(false);
   uStep2.SetOffStatePower(false);
   delay(200);
 }

 void loop() 
 { 
   //move ustep as desired
   uStep.GoToRelativePosition(-8000);
   uStep2.GoToRelativePosition(+5000);
  
   uStep.SetSpeed(200);
   uStep2.SetSpeed(250);
   uStep.SetSpeed(250);
  
   //halt if desired
   stop(); 
 }

 //indefinitely stops execution until reset button is pressed
 void stop() 
 {
   while(1) { }  
 }
