Re: [PD] control openDMXusb interface from pd-extended
by Vincent Rioux 26 Feb '09

26 Feb '09

hola roberto, my experience is that you should use wtf2osc and osc objects from Martin Peach that you will find in pd-extended. i had good results with a dmxusb-pro but i don't know how the 'open' hardware version responds... please let us know if it worked for you... good luck ps: i wish i could find some time to package some scripts+patch for this pb soon...

Array that scrolls from right to left
by Sebastien Lelong 26 Feb '09

26 Feb '09

Hi guys, I've recently discovered Pure Data as versatile platform I could use to build a robotic GUI. The idea is to collect data from a robot, send it to an OSC (open source control) server, get the data in pd~ and deal with it. One important aspect would be to plot data, in real-time, so the graph scrolls from right to left, and data is appended to the end of array (right) (well, I hope what I write is understandable...). So far so good, I've been able to build all the OSC part, and even plot things in a array in pd~, but I can only find a way to plot data from left to right, and when array's end is reached, clear it and start from beginning again. In other words, I can't make it scroll... Is there a common, usual way to do this ? Should I use "struct", "pointer" and other kind of advanced stuffs ? Is there any externals I could use or base on to build this ? Thanks in advance for your help, Cheers, Seb -- Sébastien Lelong http://sirbot.org

Workarounds for number truncation >6 digits?
by Florian Hollerweger 26 Feb '09

26 Feb '09

Hi, I'm picking up a thread here from November last year: As IOhannes has pointed out at http://lists.puredata.info/pipermail/pd-list/2008-11/065883.html the Pd editor truncates long numbers to 6 digits (which of course has nothing to do with Pd's floating point resolution). IOhannes has also noted that behind the GUI, the "correct" numbers (i.e. the ones that were initially typed) are still being used, leading to interesting situations like two [route 1e+06] boxes with different behavior. However, when the patch is closed and re-opened, the _truncated_ (i.e. "incorrect") numbers are applied. While this complies with Pd's "the picture is the patch" philosophy, it obviously can lead to problematic situations. A workaround was suggested by Nick Mariette: http://lists.puredata.info/pipermail/pd-list/2008-11/065890.html I was wondering whether anybody else would share their strategies with regards to this problem? I am guessing that another workaround would be to totally bypass the editor and run Pd without the GUI? (Which doesn't seem to make the development process very convenient, though.) Any other ideas? Thanks, flo.H

Pd-extended 0.41.4 Windows build

I got a Windows machine to build the latest Pd-extended, hopefully soon, there will also be nightly builds for Windows again. Give this one a test and see how it works: http://bxmc.poly.edu/pdlab/Pd-0.41.4-extended-20090225.exe .hc ---------------------------------------------------------------------------- Man has survived hitherto because he was too ignorant to know how to realize his wishes.

Hey, Thanks for the note, I am cc'ing the pd-list since this is of general usefulness. I don't know of a way off hand to prove that this is actually me, and not a phishing attempt. If the installer asks you for any bank info, don't give it ;). Some virus checkers used to label the Pd-extended installers as infected with virii too, tho they were wrong. .hc On Feb 25, 2009, at 3:56 AM, Lukasz Jastrzebski wrote: > Hi! > > Google marked your (quoted below) message as dangerous (phishing; > seder could be other sender than it seems to be) (in Polish: > "Ostrzeżenie: Nadawcą tej wiadomości może być w rzeczywistości > inna > osoba niż ta, która została podana.

startup problems
by Conor Higgins 25 Feb '09

25 Feb '09

Hi guys, I am working on an art project at the moment and I am using PD to design the system that we will be exhibiting, now for some reason the artist can't seem to get PD to actually run properly on his own laptop, a macbook 13". We have tried everything with regards the startup paths, reinstalling, deleting the plist files, even reinstalling the operating system just last week, yet we are still getting the same problems with the software. Pretty much every other library can be loaded manually, i.e adding it to the startup path, except for those that involve video manipulation or graphics manipulation e.g. Gem, PDP, PiDiP etc. If you look at the startup window image below you will see that the errors having something to do with x11. We tried installing x11 to combat this error, but for some reason it will not allow us to do this either giving an error message stating that a newer version of the software already exists, which it doesn't... we have scanned the system looking for it and it isnt there. Has anybody here got an idea as to why this is happening? Thank you, Conor Higgins

Pd-extended on Ubuntu Intrepid 64bit success
by danomatika 25 Feb '09

25 Feb '09

Howdy all, I got PD-extended to build a 64bit deb for Ubuntu 8.10 Intrepid following the guide on puredata.org: http://puredata.info/docs/developer/64BitLinux I added a few notes to the guide and I will see what happens when I setup my full environment. For pdp: I had to add a 3rd argument to the open function on line 141 in /externals/pdp/modules/generic/pdp_rawout.c, apparently creating new files now requires a permission for said file. I used 0666. --- Dan Wilcox danomatika.com robotcowboy.com

A non-leaky stopwatch
by Phil Stone 25 Feb '09

25 Feb '09

Hello, Attached is a stopwatch, derived from [maketime], that doesn't pollute the symbol table (i.e., indefinitely leak memory), thanks to Frank B.'s idea for keeping the symbols re-usable. It has one-second grain, so it does not keep track of partial seconds between stops and restarts-with-no-reset. However, it is quite accurate after resets and when first started. I learned that metro sends an immediate bang when started -- something I had never paid attention to before. So [ps-stopwatch] always skips the first bang out of [metro] (after reset) so that it isn't one second ahead. It counts up to 99 hours, 59 minutes, and 59 seconds, then wraps back to zero. It would be easy to make this a finer-grain stopwatch, down to the inherent resolution of [metro]. However, for my purposes (timing of live performance) one-second grain is quite adequate, and not too CPU-hungry. Thanks again to Frank for this elegant solution.
