Re: [PD] servo control
he pablo if you wanna use the parallax servo controller i'll have a python script at hand. & also how to hack a servo for turning more than 360° & still havin a reference/'0'point. & i've also a schematic for an h-bridge (l298n max.46V;4A)somewhere. lemme know if this may help best olsen On 10/7/07, p d <[EMAIL PROTECTED]> wrote: > Hello all, > I'm trying to control motors from pd.

Is it a servo/stepper/dc motor? Bipolar steppers or reversible dc motors need to be controlled by an H-bridge circuit. Servos can be hacked to rotate continuously but usually only have a 180 degree range of motion. If you have an H-bridge circuit you could use the Arduino with pd to control it. The servo controller just needs a serial port. Here's some info about steppers: http://www.piclist.com/techref/piclist/jal/DrivingBipolarStepperMotors.htm Martin ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
[PD] servo control
Hello all, I'm trying to control motors from pd. A few post in the pd-list deals with that problems, but from user-experience, i would like to know which one is the easiest one . The Parrallax Servo Controller seams to be a cheap solution, like Martin Peach explained but how is it working? Is it possible to control a bipolar motor (I need them to drive a toothed rack backward and forward)? Any help is apreciated. Thank you. pablo _ Ne gardez plus qu'une seule adresse mail !

Re: [PD] servo control with pduino
It would be very nice to control servos with Pduino, but because of timer/interrupt issues, it's not really possible to include servo control in the standard firmware. Please prove me wrong! :D Otherwise, I am currently in the process of turning the Firmata protocol into an Arduino library. The idea there is to have specific firmwares that you can use with the [arduino] object. For example, a special firmware that just controls servos, or gets data from ultrasound range finders. .hc On Jun 27, 2007, at 10:48 AM, olsen wrote: > Hi > so far for servo movements i'm using the Parallax Servo Controller > PSC(USB) & a python script for sending the ascii paragraph to > controll it. > since the release of pduino 0.3 anyone played around with servos on > pduino - would be a nice improvement to pduino controlling servos?! > let me know if i could bear somewhere a hand on this > greets > olsen > > > > > > > > > > > > -- > Planet Pluto bleibt! > > > ___ > PD-list@iem.at mailing list > UNSUBSCRIBE and account-management -> http://lists.puredata.info/ > listinfo/pd-list All information should be free. - the hacker ethic ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
[PD] servo control with pduino
Hi so far for servo movements i'm using the Parallax Servo Controller PSC(USB) & a python script for sending the ascii paragraph to controll it. since the release of pduino 0.3 anyone played around with servos on pduino - would be a nice improvement to pduino controlling servos?! let me know if i could bear somewhere a hand on this greets olsen -- Planet Pluto bleibt! ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
