Puredata external for websocket communication.
by Rafael Vega 05 Jun '13

05 Jun '13

Hi. I started working on a pd external that allows communication with a web browser using websockets. My use case is developing a GUI in html/javascript and sending messages to pd-extended using the websockets javascript API, no proxy or other scripts needed, just my external. You can take a look at it here<https://github.com/dancing-skeleton/dancing-skeleton/tree/master/pd/externa…>. There's an example patch and html file that explains how to use it. Feedback is welcome :) Where is the "central" place for this sort of thing? I'll move this to it's own repository and post it there in the next few days. Cheers. -- Rafael Vega email.rafa(a)gmail.com

Re: [PD] Forwarding serial data through an Arduino (with firmata) to a serial display
by Dan Wilcox 05 Jun '13

As you're on Linux, the port number assignment is probably tagged to the specific usb bus port and ca change. You can have them assigned to the same serial port # each time if you create a little udev rule for both the arduino and the serial port adapter and specify what you want them to be or create a symlink to say /dev/ttyArduino & /dev/ttyLCD ...

Forwarding serial data through an Arduino (with firmata) to a serial display
by Ingo 05 Jun '13

05 Jun '13

Hi everybody! I am dealing with the problem that I have changed to a new mainboard which doesn't have a serial port anymore. I'm on Ubuntu Natty. I used to send LCD display data to my remote on the normal serial port using [comport]. The display itself has a serial interface. The remote uses a separate cable and [comport] for USB going to the arduino. Is it possible to transfer the serial data for the display through the arduino using the arduinos serial out to feed the display (with a baud rate of 19200) ? I still need to use firmata for all other arduino stuff. So it should be like an addon to firmata. Or is this already possible with the current firmata? If anybody has done this before I'd appreciate any help! Ingo

[PD-announce] issiconvert
by Funs Seelen 05 Jun '13

05 Jun '13

Hi all, Just a short announce of the release of `issiconvert', a pd library which does some simple conversions between integers and symbols: [int2shex] convert (int) float to symbol of a hexadecimal value with `0x' prefix [int2sdec] convert (int) float to symbol of a decimal value with `0i' prefix [int2soct] convert (int) float to symbol of an octal value with `0o' prefix [int2sbin] convert (int) float to symbol of a binary value with `0b' prefix [sany2int] convert a symbol of any of the four types (with prefix) to (float) int [symbol2clist] output a list of floats for the corresponding character values of a symbol [strlen] calculate number of characters in a symbol [symbol2symbol] output the input if symbol $ git clone git://git.code.sf.net/p/pd-issiconvert/code issiconvert https://sourceforge.net/projects/pd-issiconvert/files/latest/download?sourc… Comments are welcome at the project page, my personal mail address or pd-list.

linux best for pd? / "best linux" for Pd? / On a Mac?
by Alexandre Torres Porres 04 Jun '13

04 Jun '13

Hi there, correct me if I'm wrong, but it seems Pd runs smoother in Linux than in any other OS, is that right? Perhaps some of you have run benchmarks for it with the same machine and diferente Operational Systems. I was curious to try myself. Now, is there a "best linux" for Pd? Maybe one that allows you to tweak in a little more to have insanely low latencies? Yeah, the whole point and interest is to try and reach an absurdly optimized latency and CPU load. Now that I got myself a Raspberry Pi (my first linux) I wanna enjoy the opportunity/motivation to broaden my linux usage to my regular laptops. I use macs by the way. Don't know if that is an issue. Like being next to an impossible task to install a nice hardcore ("the best one") linux distribution in it. I've seen that recently Linux has been able to work (poorly at least) with Thunderbolt. I have an RME Multiface that seems to works well on linux. Since newer macbooks lost the PCI slot, all that I'm missing is that my thunderbolt to PCI slot adapter works in Linux. That'd be cool, to run it on my macbook air, on linux... but I digress. Thanks Cheers

Hi all, Just pushed a new version with Peter Brinkmann's latest latency tweaks. Seems pretty solid and subjectively much faster. Also bundled are a bunch of tweaks and fixes from Antoine Rousseau. http://droidparty.net/ Have fun! Cheers, Chris. -- http://mccormick.cx/

Re: [PD] linux best for pd? / "best linux" for Pd? / On a Mac?
by Alexandre Torres Porres 04 Jun '13

hi there, as I said, had no pen drive to test shumamis as they pointed, then I burned several discs (not only shumamis distro) and none would boot. but as it turns out, my SD card on a USB adaptor works as a pen drive, so I tried burning it as required and IT WORKED... It booted, and went into a Live CD action right from the SD-USB to my Macbook air. I am actually writing this email from Shumamis. Thanks!!! trackpad seems to respond weird, keyboard not configured right, but other than that, it fucking works! Got excited... will try to sort the booting system correctly as you pointed. That sounded a bit complicated, but for the best. Seems I will finally try out Live Electronics Performance from Pd in Linux, haha Cheers 2013/5/30 Esteban Viveros <emviveros(a)gmail.com> > Maybe I can be wrong, but to work with pd in realtime performances you > will need a kernel patched with rt features.
