Re: Data analysis with PD and VASP
by Thomas Grill 03 Mar '04

Hi Armindo, > Do you think i can achieve my goal with VASP? Can you give some tips/hints of what to check or some useful links, other libs, externals, etc.? > Your help would be extremely welcome because i am on a deadline to get this done and i'm really "freaking" out as i'm kinda stucked... The answer is yes, but naturally, as with every larger package, VASP needs some warmup time to become familiar with it. > - the min and max value in an array vasp.min?, vasp.max? > - whithin this 2 minute window, i need to know if the slope of the values is increasing or decreasing vasp.dif -> vasp.sum? (you need the cvs version for that) > - getting some kind of information about the possible frequency of the graph vasp.rfft -> vasp.gate, vasp.max? etc. best greetings, Thomas

data analysis with PD
by type_non 03 Mar '04

03 Mar '04

I have a project where i need to analyse the HR, GSR and Muscular signals, and from that, trigger some PD patches. I need to analyse this data inside PD. I'm thinking of gathering the data into 3 arrays, one for each signal, and with a 2 minute interval, i will analyse the data. Problem is the analysis of the arrays... I found an object in IEMLIB that gives me the average of the values in an array. That is helpful, but i need some more info, like: - the min and max value in an array - whithin this 2 minute window, i need to know if the slope of the values is increasing or decreasing - getting some kind of information about the possible frequency of the graph Is this possible? Or do you know of some useful externals that can give me what i want or help me to get the info i need? Thanks in advance. --------------------------------- Yahoo!

'Reading' a patch or subpatch
by Padraig Kitterick 03 Mar '04

03 Mar '04

Hi all, I am reading in configuration data from a device, translating that into a network of PD objects and sending messages to a sub-patch (using pd-msg) to effectively 'draw' the configuration for the user in the sub-patch. As it is clear that you can send messages to a PD patch/sub-patch to draw and manipulate objects this part is not a problem. However, if / when the user changes anything in that sub-patch I want to be able to receive a list of what is in the sub-patch and how they are connected so that I can send the updated configuration to the device. This I have no clue how to do! So... is there a way to receive the contents/connections in a sub-patch in the form of pd messages, e.g. 'obj x y ....', 'msg x y ....', 'connect 0 1 0 2', etc. Thanks in advance, Padraig Kitterick

delwrite~, FIR~, external data rate?
by matthew jones 03 Mar '04

03 Mar '04

Firstly, sorry for the heap of questions!! hope somebody can help, big complex patch/external plans ahead..... (1) If I write an external, is there someway to avoid excessive calculations from interrupting the audio? so if the external is an audio signal external, is it possible to do some of the calculations at 'data' rate so it will just keep calculating until it is finished without causing nasty glitches in the audio output? (2) Is there some way of grabbing the circular buffered data stored in a delwrite~ for use with calculations?? a delwrite~ called the same as an array on screen seem to have nothing to do with each other. (3) Any idea how to implement cross-correlation? FIR~ is suited for short filters is it not? I need to be convolving long signals (maybe with artificially decreased sample rate - how to do this on-the-fly too??!) thanks in advance for ANY help at all!

Re: [PD] pidip osx

Hi Sevy & List! thanks for the advice, i ran a "make" in pdp_pidip_osx directory and strangely got a linker error: ld: can't locate file for: -lmp3lame So i went to install libmp3lame via fink. after that i did another "make", with the error being: ld: can't locate file for: -lImlib2 but there is no Imlib2 in Fink, although, i got all necessary libs fink-installed of course! I am happy for any hints!

pdsend and pipe question
by Bill Sack 03 Mar '04

03 Mar '04

hi, so i've made a little app that reads info from my serial device (a pontech sv203) and reports it to the terminal window via printf printf("%d;\n", numbl); it works great - sends numbers marching down the term: 89; 90; 92; <etc.> i want to send this data to pd ... started my app into a pipe to pdsend: ./my_app /dev/ttyS0 | pdsend 3000 a matching [netreceive 3000] in pd reports successful connection, but nothing comes through the right outlet. not sure what's wrong here ... when i do this: pdsend 3000 bla bla bla; the line appears as it should through pdreceive. what am i doing wrong? thanks for any hints, bill -- _________ Bill Sack wsack(a)acsu.buffalo.edu ----------------------

radio button send not working
by MilesOkazaki＠aol.com 02 Mar '04

02 Mar '04

Pd list, Is there a reason why I can never get the radio button "send-symbol" to work? they will receive, but in order to send something I have to attach a number box and send from that instead. thanks, M.Okazaki

plugin~ and jack with pd -rt

hi, i'm running pd -rt -jack with the plugin~ external: turning on audio in this patch (in attachment) can (not always) load my cpu to 100 percent and then gives lots of watchdog: signaling pd... i don't think that the problem is related to this new ladspa plugin (caps) cause others, like VyNil, do the same thing. i've this informaton in my terminal: subgraph starting at pure_data_0 timed out (subgraph_wait_fd=11, status = 0, state = Triggered) **** alsa_pcm: xrun of at least 1.538 msecs cannot read event response from client [pure_data_0] (Connection reset by peer) is the plugin~ external fully compatible with pd-0.37.1 and jack? patrick #N canvas 460 247 356 207 10; #X floatatom 28 71 0 0 0 0 - - -; #X obj 272 166 dac~; #X msg -19 96 print; #X obj 28 131 plugin~ Click /usr/lib/ladspa/caps.so; #X msg 28 96 control bpm \$1; #X floatatom 141 71 0 0 1 0 - - -; #X msg 141 96 control volume \$1; #X obj 141 20 loadbang; #X msg 141 42 1; #X text 27 52 BPM; #X text 172 72 VOLUME; #X connect 0 0 4 0; #X connect 2 0 3 0; #X connect 3 1 1 0; #X connect 3 1 1 1; #X connect 4 0 3 0; #X connect 5 0 6 0; #X connect 6 0 3 0; #X connect 7 0 8 0; #X connect 8 0 5 0;

Re: [PD] pidip osx

Hi Sevy! Dear List! Thanks for the help! I already got pdp from zwizwa.fartit.com running on osx 10.2.8. so i wondered if pidip is a seperate library, would i have to load a pidip.pd_darwin at startup? As i can see now, when i take the "combined" pdp_pidip_osx package from yves' site, there is one pdp.pd_darwin file wich includes both libs. ok. So i went on to give it a try and got an error: pd can't open library: /usr/X11R6/lib/libXv.1.dylib (No such file or directory, errno = 2) This must be about the video output of the X-server, but since i don't use osx 10.3 i'm still using apple's additional X11, and it might not support the same stuff as Sara's and Rob Canning's X11 from osx 10.3. But, i have an libXv.a file in my /usr/X11/lib. Sorry to keep the list buisy with osx/pdp issues, but it's alltogether really exciting stuff! :-) Peter~ Quoting Yves Degoyon <ydegoyon(a)free.fr>: > hi, > > yep, pidip is a separate library, additional to pdp..... > > >> http://zwizwa.fartit.com/pd/pdp > >> http://ydegoyon.free.fr/pidip.html > > but, in the mac osx package, both are delivered together, > so i have problems figuring out your problems > if you followed sara's or rob's instructions, > you should have both o nada, no? > > cheers, > sevy > > plessas(a)sbox.tugraz.at wrote: > > >Dear List, > > > >i got pdp running on my osx 10.2.8 box, but i don't yet understand how to > load > >or use pidip objects. from a recent posting to this list i read from > somebody's > >console that the loading of pidip is printed as a sepaate line at pd > startup, > >so it has to be a library, right? do i have to compile pidip? i got the nice > >pdp_pidip_osx package and i am just able to use the pdp objects. > >perhaps this is a simple question, but i never tought of pidip being a > separate > >library, other that pdp. if someone can help me with my confusion, i'd be > glad > >to hear all your suggestions! > > > >Have a nice time! > > > >Peter~ > > > > > >_______________________________________________ > >PD-list mailing list > >PD-list(a)iem.at > >http://iem.at/cgi-bin/mailman/listinfo/pd-list > > > > > > >
