Building Pd App on OSX
by Jonathan Wilkes 27 Jul '13

27 Jul '13

Miller et al, Once I get Pd built on OSX, I can make install so that "pd" from the terminal will launch it. But how do I make it into an App? Any hints? INSTALL.txt doesn't have anything. I'd like to get it building so that a) I can make use of all the goodies someone put into AppMain.tcl and b) post a working copy so people can try out the new Preferences dialog. Separate question: even for running "pd" from the terminal, why doesn't the AppMain.tcl stuff get used? For example, I still want to use the OSX "Preferences" panel, and set all the Apple specific stuff like "About Pd" in the App menu, regardless of how pd was started. (Though it's not a huge deal, as the vast majority would just be running the app.) Thanks, Jonathan

Raspberry Pi Behringer UCA222 boot problems
by John Canning 26 Jul '13

26 Jul '13

Hi Folks, I have been trying for quite a while to get my Raspberry Pi to work in full duplex with Pd. I have installed the OS on the PdPi site and updated it. I am using a Behringer UCA222 for audio. When I change the USB speed down to 1 (dwc_otg.speed=1) in /boot/cmdline.txt my Pi won't boot with the soundcard plugged in. If I unplug the soundcard the Pi will boot but as soon as I plug it in the Pi crashes. Has anyone got any suggestions about why this is happening? Thanks, John

CPU usage of [mtx_*~]
by Alexandros Drymonitis 26 Jul '13

26 Jul '13

If you want to increase the gain of a single connection, using [mtx_*~], is this more CPU friendly: [0\ | [element 1 1 $1( | | [osc~] | | [mtx_*~] than this: [element 1 1 1( | | [osc~] | | | [*~] | | [mtx_*~] I mean, does [mtx_*~] calculates the gain for a given connection only, with [element(, or does it calculate the whole matrix? Hope what I'm asking is clear?

where can I find [udpsend] and [udpreceive]?
by Alexandros Drymonitis 26 Jul '13

I've just compiled the osc library in Pd vanilla (wasn't it called mrpeach?) but [udpsend] and [udpreceive] are not included? Where can I find them? Can't seem to find them in Pd's website..

pix_openni blocks pd gui
by Antoine Villeret 26 Jul '13

26 Jul '13

hi, i'm working on pix_openni code and trying to figure out why pd is blocking 4 or 5 seconds when quitting after using [pix_openni] the gui stays alive and the command line shows "watchdog: signaling pd..." 4 or 5 times then the gui disappear how can I figure out what is blocking pd ? thanks a -- do it yourself http://antoine.villeret.free.fr

[PD-announce] new version: Extended View Toolkit v0.4 Rotterdam
by Peter Venus 25 Jul '13

25 Jul '13

Hello All! We proudly announce the new version of ExtendedViewToolkit - the PureData/GEM abstraction library for panoramic image/video creation and projection mapping. It has been a long, but productive time since our last release. Tons of new features and fixes wait for being discovered by you. This new version was mainly done during a residency at moddr_/WORM in Rotterdam. Amongst other changes, you are looking on a completely re-designed storage-solution, that enables you to create scene-based video-mapping setups - with the possibility to add transitions between your scenes. Within each scene, you can automate basically every parameter in every module of the toolkit individually. We made a small technical teaser, to show what's possible with the scenes: http://vimeo.com/51567993 In addition to our multi-camera panoramic content solution, we integrated a module for creating 360-degree panoramic content made with spherical, one camera based, lens- or mirror-systems. Also, a new video player with instant and saveable controls for in/out-points, fade-times and loop, waits for being used within your performance. On the projection-side we added a module with 5x5 cornerpoints to allow more detailed settings when projecting on uneven surfaces with just one projection module. Furthermore we implemented a function to adjust the perspective distortion into the projection modules. We sticked to our fear of externals and made the whole toolkit out of plain PD and GEM without any other external libraries. For the usage of the remote-control features we recommend the usage of mrpeach´s OSC library. We tested the toolkit on different machines, and did not have any issues on Linux, OSX 10.6.8, 10.7.1 and also on Windows 7. If you discover any problems, please get in touch with us. Thanks to all the people who constantly support the development of the toolkit, especially Cyrille Henry, IOhannes, Seppo, Walter&Birgit of moddr and Patrick Pagano. Download it here: https://github.com/extendedview/extended_view_toolkit If you use it, we strongly encourage you to send us links, videos, images, etc. of your projects. We are amazingly interested to see what you create! Cheers, Peter & Marian http://extendedview.mur.at _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

Re: [PD] gpio on the raspberry pi from within pd ?

Hi Dan, I am Cc'ing the list, which is really your best resource.

Re: [PD] gpio on the raspberry pi from within pd ?
by Dan Nigrin 24 Jul '13

24 Jul '13

Thanks Thomas – damn, I thought all pins were 5v – I saw that there was a power pin at that level, and assumed the others were too. So when you say "PWM is easily configured" - do you mean that it is some setting that I adjust on the Pi itself, and then getting a variable voltage is as simple as sending a value between 1 and 1023 from Pd to the Pi? Or do I have to do some programming within Pd to do the actual PWM? If this is the case – that's exactly what I need help with, not sure how to do that. Thanks!!

Hi ! PWM on RPi is easyli configured, with a value from 1 to 1023. Be careful only some GPIO are PWM : https://www.modmypi.com/blog/raspberry-pi-gpio-en-franais The voltage output will be 3V3 @100%, I have to check this, but pretty sure.
