How to decrease the delay between functions. Useing arduino to controll stepper motors.

Hi,

We are working on project, were we need to controll two steppers motors, useing arduino with a adafruit v2 motorshield.

We have two problems:

1. Ii it possible to get the two motors running at the same time? Using only 1 arduino bord with both motors connectet to the motorshield.

2. When we run our functions, there is quit a big delay between them. Is it possible to reduce the delay?

We are using the matlab packede for arduino. We run each motor with a function like:

-----------------------------------------------------------------

function motor2(x)

a = arduino('com3', 'uno', 'Libraries', 'Adafruit\MotorShieldV2');

shield = addon(a, 'Adafruit\MotorShieldV2');

sm = stepper(shield, 1, 200); sm.RPM = 30; move(sm, x);

end

----------------------------------------------------------------------------------

To run the motors we just use a simpel script like:

---------------------------------------------------------------------------

for idx=0:2

motor1(100) motor2(100) motor2(-100) motor1(-100) end

clear idx

-----------------------------------------------------------------------

Hope that some are able to help :-)
