How to enable pins

[brent]

Hello,

I'm attempting to drive three stepper motors using an arduino mega and
quadstepper from sparkfun. I need to enable them in order for them to
move. How do I set my enable pins? The following is my code:

#include <AccelStepper.h>

// Define some steppers and the pins the will use
AccelStepper stepper1(1, 2, 23);
AccelStepper stepper2(1, 4, 27);
AccelStepper stepper3(1, 5, 29);

void setup()
{
stepper1.setMaxSpeed(11000.0);
stepper1.setAcceleration(10000.0);
stepper1.moveTo(6000);
stepper1.enableOutputs();

stepper2.setMaxSpeed(11000.0);
stepper2.setAcceleration(10000.0);
stepper2.moveTo(6000);
stepper2.enableOutputs();

stepper3.setMaxSpeed(11000.0);
stepper3.setAcceleration(10000.0);
stepper3.moveTo(6000);
stepper3.enableOutputs();
}

void loop()
{
// Change direction at the limits
if (stepper1.distanceToGo() == 0)
stepper1.moveTo(-stepper1.currentPosition());
if (stepper2.distanceToGo() == 0)
stepper2.moveTo(-stepper2.currentPosition());
if (stepper3.distanceToGo() == 0)
stepper3.moveTo(-stepper3.currentPosition());
stepper1.run();
stepper2.run();
stepper3.run();
}


Thank you,
Brent

Hello,

enableOutputs() sets the configured pins to output mode, so for example for
your stepper1 the call to stepper1.enableOutputs() sets pins 2 and 23 to
output mode and then uses them for pulsing the stepper.

Cheers.

Mike,

I believe the quadstepper requires the use of enable pins (that need
to be defined) in order to work. I've tried running the code that I
posted above with no results.. are you saying that it should work?

I should have asked: how do I incorporate setEnablePin for each motor
into the code i posted above?

Hello,

AccelStepper does not manage enable pins for steppers,. You should set them
yourself.

Cheers.

Hi again,

Sorry, I gave the wrong answer.

If you configure an enable pin eg:
stepper.setEnablePin(7)

then pin 7 will be set/cleared when you call enableOutputs()/disableOutputs()

Cheers.
