Dependencies:   StepperMotorUni mbed

Dependents:   StepperMotorUni_Hello

Sample code for stepper motor operation with StepperMotorUni library

4 output pin generates signal for stepper motor driver.

/media/uploads/okano/unipolar-steppermotor-sample.png

This library can operate in parallel for multiple stepper motors.

The mbed generates pulses on 4 output pins for external driver stage.
The StepperMotorUni library can generate 3 types of pulses.

1 phase drive (wave drive) 

#include "mbed.h"
#include "StepperMotorUni.h"
 
StepperMotorUni motor( p26, p25, p24, p23 );
 
int main()
{
    motor.set_operation_phase_mode( StepperMotorUni::ONE_PHASE );
    ...
    ...

2 phase drive 

#include "mbed.h"
#include "StepperMotorUni.h"
 
StepperMotorUni motor( p26, p25, p24, p23 );
 
int main()
{
    motor.set_operation_phase_mode( StepperMotorUni::TWO_PHASE );
    ...
    ...

1-2 phase (half step) drive 

#include "mbed.h"
#include "StepperMotorUni.h"
 
StepperMotorUni motor( p26, p25, p24, p23 );
 
int main()
{
    motor.set_operation_phase_mode( StepperMotorUni::HALFSTEP );
    ...
    ...
