Accel Stepper Library Help

hello,

i working on rfid enabled door unlocker using arduino uno pololu drv8825 stepper driver, , rc522 rfid module. im struggling getting stepper motors turn.  the code long post entirely here im going post chunks of important parts question here:

important note:  i have following code working on arduino:

code: [select]

// constantspeed.pde
// -*- mode: c++ -*-
//
// shows how run accelstepper in simplest,
// fixed speed mode no accelerations

#include <accelstepper.h>

accelstepper stepper(1, 4, 3);


int slp = 8;


void setup()
{  
  digitalwrite(slp, high);
  //attachinterrupt(buttonint, unlock, rising);
  
   stepper.setmaxspeed(100000);
  
   stepper.setacceleration(100*4);
   stepper.moveto(50*8);
}

void loop()
{  fun();
  
  

}

void fun()
{stepper.run();
}
  

now not working code:

first include accelstepper library

and tell library pins hooked up:

accelstepper stepper1(1, 4, 3);

then under void setup();

i set max speed, acceleration, , distance

code: [select]

stepper1.setmaxspeed(10000);
  stepper1.setacceleration(100*4);
  stepper1.moveto(50*8);

then on main loop.  this check eeprom see if card stored.  

code: [select]

if ( findid(readcard) ) {        // if not, see if card in eeprom
        serial.println("welcome, shall pass");
        opendoor();                // open door lock
      }
      else { // if not, show id not valid
        serial.println("you shall not pass");
        
      
        delay(10);

warning:  i beginner coder code no means close perfect.  i trying best work optimize it.  

now functions defined open door:   arduino runs wakedriver() function sets slp (sleep pin) high.  the stepper motor under holding torque.  unfortunately dosent anthing else h

code: [select]

void wakedriver()
{
  
   digitalwrite(slp, high);    //power driver sleep
    delay(10);                 // pause while driver wakes up
  
}

void opendoor()
{
  wakedriver();                //run wake driver  i have driver waking , @ holding torque
  stepper1.run();              //make stepper run based on done in setup
  if (stepper1.distancetogo()==0)      //if motors have moved designated amount
  {door();}                            //run door else have steppers continue running.  not sure if needed.
  else
    stepper1.run();
    
}

void door()
{
  if (digitalread(doorswitch)==high);        //check see if switch pushed
      lockdoor();                             // if lock door
}

void lockdoor()
{
  
   stepper1.moveto(-50*8);                    //move steppers in opposite direction lock door.
   digitalwrite(slp, low);                    //put driver in sleep mode power down stepper.
}
    


any , appreciated

tyler

first, need post code can see overall picture. can add attachment. problems in parts don't look.

the thread stepper motor basics may helpful. simple stepper code not need library.
