Hi Arnaud,

I tested your new ardublock for Stepper.
It's a good job.
But i've a problem. I can't change the rpm for the same motor.

Look this program and if you can test.

Hi Arnaud,

I find a solution. But could you create a block for that ?
It will be super.

Look, we can change rpm like this.

Hi,

Here we are ! I found an alternative solution for my problem with Eclipse.

There is 4 methods to drive steppers with adafruit MotorShield:

• stepper_motor.step(nb_de_pas, FORWARD, SINGLE);
• stepper_motor.step(nb_de_pas, FORWARD, DOUBLE);
• stepper_motor.step(nb_de_pas, FORWARD, INTERLEAVE);
• stepper_motor.step(nb_de_pas, FORWARD, MICROSTEP);

I use the DOUBLE method

• SINGLE - One coil is energized at a time.
• DOUBLE - Two coils are energized at a time for more torque.
• INTERLEAVE - Alternate between single and double to create a half-step in between.  This can result in smoother operation, but because of the extra half-step, the speed is reduced by half too.
• MICROSTEP - Adjacent coils are ramped up and down to create a number of 'micro-steps' between each full step.  This results in finer resolution and smoother rotation, but with a loss in torque.

Is there any chance to make it works with new Adafruit Motor Shield v.2.3? Thanks in advance

[christop...@hotmail.com]

Hi,
No the shield v2 doesn't work with ardublock. The librarie change, so it's impossible.
Maybe someone can create new block for v2 and add to block v1. But not delete the old block.

I find this : https://github.com/taweili/ardublock/pull/137/commits
So it's possible

Thanks
Kris
