> Hi, > this is very strange. which version of arduino language are you using? > I can't think of another problem than that... which OS? i'm using all the latest stuff, i'm pretty sure of that. i'm on gentoo linux and i have tried a round about method and bypassed the java program and compiled and uploaded myself using avrdude. this has worked. frankly i think i prefer compiling it myself rather than the java app, it seems a bit less clunky. however, it would be good to understand why it is not compiling with the java app. i think that it may not be seeing where pins_arduino.c is but i really don't know what i'm talking about. the only thing now is getting the arduino to commuicate witht the patch. i have started testing but kinda fumbling round in the dark trying to work some stuff out. i have the patch loaded and all signs are good, it is registering /dev/ttyUSB0 and reporting to me the firmware as 1.0 so i'm happy with that. i started with jamming a led into the GND and Digital 13 pins and switching one of the digital toggles on the patch. however nothing yet. i thought that might light up my life but, no. i also tried putting a potentiometer with the outer pins in 5v and GND and the middle pin into analog 2 but nope to that either. i wonder if its my electronic or skills or my fumbling skills that are at a loss here. any suggestions welcome. cheers On 3/20/07, marius schebella <marius.schebella(a)gmail.com> wrote: > Hi, > this is very strange. which version of arduino language are you using? > I can't think of another problem than that... which OS? > marius. > > we are wrote: > > so now i have my new arduino i'm getting stuck into it. > > i have made all sorts of christmas lights and the necessary tutorials > > and i'm now starting the pd exploration. > > i have everything running except when i try and compile the > > Pd_firmware.pde for pduino within the java arduino program i get an > > error that does not allow me to compile the software. > > > > > > In function `void checkDigitalInputs()': > > error: `port_to_input' was not declared in this scope > > > > and it highlights lines... 259- 272 > > > > void checkDigitalInputs(void) { > > if(digitalInputsEnabled) { > > previousDigitalInputs = digitalInputs; > > digitalInputs = _SFR_IO8(port_to_input[PB]) << 8; // get pins 8-13 > > digitalInputs += _SFR_IO8(port_to_input[PD]); // get pins 0-7 > > digitalInputs = digitalInputs &~ digitalPinStatus; // ignore pins set OUTPUT > > if(digitalInputs != previousDigitalInputs) { > > // TODO: implement more ports as channels for more than 16 digital pins > > Serial.print(DIGITAL_MESSAGE,BYTE); > > Serial.print(digitalInputs % 128, BYTE); // Tx pins 0-6 > > Serial.print(digitalInputs >> 7, BYTE); // Tx pins 7-13 > > } > > } > > } > > > > > > i don't know any c but from what i can estimate, there is no > > > > int port_to_input > > > > is this file refering to another file, or where have i gone wrong? > > > > thanks > > > > On 3/10/07, we are <gateswideopen(a)gmail.com> wrote: > >> ---------- Forwarded message ---------- > >> From: we are <gateswideopen(a)gmail.com> > >> Date: Mar 10, 2007 1:43 PM > >> Subject: Re: [PD] [PD-announce] Pduino 0.3 release > >> To: Hans-Christoph Steiner <hans(a)eds.org> > >> > >> > >> thanks hans > >> > >> can't wait to try it, but i have to as my duino is in transit damnit! > >> great to see people using this thing as i'm about to join the club. > >> ta > >> > >> > >> On 3/9/07, Hans-Christoph Steiner <hans(a)eds.org> wrote: > >>> Sure, thanks for testing it.

create object dynamically
by nanodust 19 Mar '07

19 Mar '07

Husk, This was a problem I needed to solve with one of my students last fall. This is perhaps not the only, or most elegant method, but it demonstrates at least one method of dynamic/runtime object creation within PD. http://puredata.info/Members/nanodust/.personal Hope it helps !

Binary - integer conversion
by David Powers 19 Mar '07

19 Mar '07

Hello, Is it possible to somehow convert back and forth between integer and binary in PD? My idea, is to represent simple drum machine style rhythms as binary numbers. [101010001011]. Ok, so if this were a float, it would be trivial to do a common task and shift the rhythm left or right. I think, that other rhythmic variations would also be quite fast to implement using this system, you can do binary math instead of list operations which should be much faster, I assume. ~David

a small utility: dispatcher.pd
by Frank Barknecht 19 Mar '07

19 Mar '07

Hi, attached is a small, simple, but very useful helper abstraction: [dispatcher] makes building those long [route method1 method2 method3] chains behind abstraction inlets a bit easier and also works around the problem of adding methods later on without breaking existing connections.

Re: [PD] seeking Pd programmer
by the center of the bomb 19 Mar '07

19 Mar '07

I started the project in 2005 when I met an incredible architectural acoustic in a concrete cylinder sized of 15 meter high to 10 meter large. I started to sing inside with an incredible reverberation of low sounds. The entrance of this cylinder (used to keep wine) was too small for audience to come inside, so I imagined to keep in real time the sound and the images (video) outside the cylinder, far away through Internet, in an appropriate cube-public-place with 6 video screens and 3D sound projection. I found a team of 9 people to release this opera project, but it was located near Toulouse (south of France) and in this part there is no grants for contemporary art creation. Today TEST-AIMANT is in waiting to be released. The virtual clones orchestra, in my music works, stays as an obsession: there is several exemple of, done and music in project: like in 2002 "Jeux & Interdits" (Forbidden Games) where" I cloned my 9-tone electric guitar in 4 independent clones. listen at http://centrebombe.org/mp3-free.html in 2003 "ti.Me Has No Age" where I cloned my archisonic lamp (http://centrebombe.org/lamps.html)in an orchestra of 161 clones you can listen at http://centrebombe.org/mp3-free.html My next project is also about virtual orchestra of clones "Unisolable & Unduplicable, the recipe of Freedom" http://centrebombe.org/2007.residency.proposal(the Lamplayer.vs.the.Machines).pdf The schematic of VOX CLONA (in attachment) gives you a precise purpose of what I would like to generate: one live voice (mine) generating an independant choir of 13 voices with its independent contrepoint projected in 3D sound space. I should perhaps translated in English what I wrote in French?

GEM / pix objects : limiting colours
by Sciss 18 Mar '07

18 Mar '07

hi, how can i limit the RGB channels of a film that goes through [pix_film] -> [pix_buf] -> [pix_gain] -> [pix_offset]. right now i get colour wrapping from gain + offset but i want to limit the colours. say i scale down the red channel and i add an offset to the green channel, i don't want to green channel to wrap from >= 1 to 0, but to limit all values above 1.0 to 1.0. thanks, -sciss-

lowering gem camera capture CPU overhead
by Ivica Ico Bukvic 18 Mar '07

18 Mar '07

Hi all, I've been trying to shave off precious cycles off the FW camera input capture. The problem is that vanilla capture of a FW camera feed (NTSC) already introduces 50+% of CPU overhead on an AMD64 3000+. I have experimented with lowered gem frame value, but anything below 20 seems to jagged. So, here are the questions: What is the cause of such a high capture overhead? Is there a way to minimize such overhead beyond just optimizing code for sse and other similar methods, plus the aforesaid frame option for the gem object? Many thanks! Best wishes, Ico
