I've got this code in arduino I'm trying to load into chipkit, one of the libraries doesn't seem to be supported though, could anyone help me figure out an alternative?

the <SM.h> library is the one failing for me.

#include <AccelStepper.h>
#include <SM.h>
const int buttonPin = 14; 

int buttonState = 0; 


SM Controller(Parked);
AccelStepper stepper1(AccelStepper::FULL2WIRE, 2, 3);

void setup()
{ 
  pinMode(buttonPin, INPUT);
  stepper1.setMaxSpeed(10000.0);
  stepper1.setAcceleration(14000.0);
  stepper1.moveTo(64000);
}

void loop(){
  buttonState = digitalRead(buttonPin);
  EXEC(Controller);
  stepper1.run();
}//loop()

State Parked(){//wait for sensor to be activated
    
   
  if(analogRead(A2)>600){
    stepper1.setCurrentPosition(0);
  stepper1.stop(); }
  if (buttonState == LOW) 
  { 
    Controller.Set(SlowH, SlowB);
  }
  else if (analogRead(A2)<600){
    stepper1.moveTo(-70000);}
}//Parked()

State SlowH(){// start moving forward at slow speed
  stepper1.moveTo(27000);
  stepper1.setSpeed(2000);
}//SlowH()

State SlowB(){//check remainng distance while moving
  if(stepper1.distanceToGo() == 0) Controller.Set(FastH, FastB);
}//SlowB()

State FastH(){
  stepper1.moveTo(64000);
  stepper1.setSpeed(4000);
}//FastH()

State FastB(){
 if(stepper1.distanceToGo() == 0) Controller.Set(ReverseC); 
}//FastB

State ReverseH(){
  stepper1.moveTo(0);

}//ReverseH()

State ReverseB(){
  
  if(stepper1.distanceToGo() == 0)
   Controller.Set(ReverseC);
}//ReverseB()


State ReverseC(){
  

if (analogRead(A2)>600)
{
      stepper1.setCurrentPosition(0);
      Controller.Set(SlowH, SlowB);
}
else
{ stepper1.moveTo(-70000);
  stepper1.setSpeed(-8000);
}
}

The specific error I'm recieving is : undefined reference to `timer0_millis'

What is the SM.h lib supposed to do or a link a description?

It looks like it may be some form of State Machine library.

Why not code it manually? After all, a state machine is really just a variable and a switch() construct. Check out [url]http://hacking.majenko.co.uk/finite-state-machine[/url]
