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

Another BTW - after seeing your website, I gotta tell you I've recently attended a presentation by Pip Chodorov, another die-hard 16mm film fan

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

OK, get some examples of pduino - it's absolutely the easiest way - you have to upload standard firmata onto Arduino only once, and then, everything you do is from Pd. Much easier than writing your own firmware and communicating through serial port.

It seems the example you posted is meant to be used with firmata. From the readme --

To use it, first download and install Arduino 0018 or newer from
http://arduino.cc. When you run the Arduino program, then you'll be able to
choose firmware from Arduino application, in the menu:

File -> Open -> Examples -> Library-Firmata

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

Fascinating project. What aspects of the equipment are you controlling?

Firmata is a good place to start, but I've noticed some lag, I haven't used it in years though.

I would argue that if you are not writing your own firmware, Arduino is overkill for this application. If what you need is Pd to sequence the movement of two steppers, than there are a host of existing options which do not require an Arduino. Googling "USB Stepper Controller" gives you several options, some even targeted at novice/hobbyist uses.

If you do decide to use Arduino, the experience of figuring out the language enough to do what you need will certainly benifit you in the future. ESPECIALLY if digital control of analog equipment is the kind of thing you are in to!

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

It's not difficult to sequence those messages, it is what you do with them that may pose some issues. Here's a patch, sequences are usually best done with tables or lists, but this will give you the idea.

thanks a lot....

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