Hi, I want to use this guppy-pro : http://www.alliedvisiontec.com/us/products/cameras/firewire/guppy-pro/f-201bc.html#applications

for a real simple patch... but i can't open it on PD on MAC OSX.

Someone have an idea??

thanks

Hi, I'm working again on a stepper motor with a Half-brdige driver to control it with Arduino.

Now, I need to transcode in the PD language this sequence :

1 - 0 1
2 - 1 1
3 - 1 0
4 - 0 0

This is the basic sequence for a stepper motor, did someome know how can i transcode it ??

best and thanks

Hi, I've a project to control a step motor trough pduino, I've tried with the Arduino stepper library and the system work, but i don't know how can i translate to a PD patch....

There is same example around Or someone have an idea to how control a 4wire step motor trough PD

Thanks...

Hi, I'm preparing a project with a dancer, and we would like to experiment with ANIMATA and play with live animation...
For the moment I've found eyesweb, that it's not so complicate for tracking mouvement and draw the skeleton of the dancer and then trough OSC and a little PD patch send the info to animata...
But the problem is that I'm on a MAC and eyesweb is for PC... so everything is complicated..

My question is.. someone has develpped something similar to eyesweb... I know that with PD we can do this... but i don't know how to start... and i need some help... If someone is interesting we can create a really interesting patch for the PD users...

Thanks to all that can help...

Hi,

I'm trying to connect a 110v motor to arduino and pilot with pure data...

I've made a connection with a relais 5v-125v 1A and a transistor 2N2222.

When i start after 20 second everything stop and the USB connection dosen't work...

When i try with a small motor 9vDC... everything work...

So that, I've to change the transistor Or do other modification?

This is the Link of the RELAIS SCHEMATIC :

Just a detail...
I can open the camera with I-CHAT ... so the Mac can recognize the camera... now how can i set the driver to open it on PD ??

KinoLab

thanks a lot....

I'll trying this next week... and I'll post news soon....

Thanks, I hope to be able to write this cycle.... is really important, because in this project i need to use video trough PD too... so i really need to use PD and not the Arduino language...

anyway, thanks and best

Enrico

yes, I'm using the firmata for PDUINO...

good... yes he is a friend of mine...

No, i don't know how to work in other way that the standard firmata and the pduino...

sorry, but i think that it's possible to found a way to organize the same cycle on PD...
but I'm new in pd so....

Hi, thanks for your answer, but I think that this solution is to complicate for my knowledge in PD and ARDUINO...

I try to explain you in details the project : I'va a 16mm projector and a 16mm bolex, each one is moved with a stepper motor, so i can be really precise on a 360º movement.
So the idea is to have a patch that allow me to chose 1 movement on the camera then 1 on the projector, or 2 cam and 3 projector etc... and also change the speed of the 360º...

In this link I've poste a n Exemple of patch that I'm trying to use, when you open the patch you have to double click on : "pd sending digital outs" and you have a new window.

In this windows the idea is to recreate the loop that I've send you in the post above.
The TWO specification that i need and that you see on the rugged specification are that with their drive you have :

2 - pins that you have to use with PWM
2 - pins to use with the direction

So i don't know, i remember that with a single H-Bridge and this patch i was able to drive a motor, know the idea is to use the rugged driver....

I hope to be more clear...

Thanks...

Hi, this is the driver that i connect to arduino : http://ruggedcircuits.com/html/rugged_motor_driver.html

in arduino I've a patch that read the PWM of two pin and i need to write a sequence like this with the digitals output :

void StepperHighSpeed::stepMotor(int thisStep)
{
if (this->pin_count == 2) {
switch (thisStep) {
case 0: /* 01 */
digitalWrite(motor_pin_1, LOW);
digitalWrite(motor_pin_2, HIGH);
break;
case 1: /* 11 */
digitalWrite(motor_pin_1, HIGH);
digitalWrite(motor_pin_2, HIGH);
break;
case 2: /* 10 */
digitalWrite(motor_pin_1, HIGH);
digitalWrite(motor_pin_2, LOW);
break;
case 3: /* 00 */
digitalWrite(motor_pin_1, LOW);
digitalWrite(motor_pin_2, LOW);
break;
}

did someone can help me ?

Thanks

Hi, thanks for your answer, but i need to pilot two stepper motor from PD trough Arduino, i'm writing an application that need to be possible to make change live and in real time...

best

En

It works, but i can't use the sames speed of the stepper library of Arduino....
Someone have an idea ?

Yes, I'm using a SN754410NE Driver and I've think in this possibility with pduino.... I'll try later, and I'll say you if works.

Thanks

Hi sonsofsol... thanks for your links...
I'll look them... but i think that everything is for PC and I've only a Mac...

Best to you
