Re: [PD-dev] compiling to DSP processor?
hey Hans + Miller, thanks for pointing me towards Sukandar's work. so to be clear: you think i'd be able to take the Pd source code and just push it through the DSP's compiler and something vaguely usable would come out? (I have never done anything with a DSP chip before and the examples on TI's website are fairly heavy on the assembler, they mostly look like microprocessor bit-bangy code..) cheers damian On 02.04.2012, at 19:37, Hans-Christoph Steiner wrote: Yeah, I imagine with no kernel doing timeslicing, Pd would literally have all of the CPU time, and the audio output to the hardware happen more often than every 64 samples. .hc On Apr 2, 2012, at 11:31 AM, Miller Puckette wrote: It should be possible but Pd needs stuff like open(), read(), and write() for files, so it's necessary to make a small library to either carry out or somehow fake those operations. The great advantage of running Pd on a DSP is that you can probably get audio latencies down much further than on a PC-like CPU. cheers Miller On Mon, Apr 02, 2012 at 10:58:49AM -0400, Hans-Christoph Steiner wrote: Hey Damian, The gluiph was just that, it ran Pd directly on a DSP: http://www.nime.org/proceedings/2003/nime2003_180.pdf Depending on your skills, it could be easier to run a über-stripped OS like I did on the Palm Pilots, which ran Pd tho they had 32megs of RAM.

At this point I'm able to use the PdBase class for control-flow patches, but I can't get audio working. For some reason, it doesn't register audio units as the chosen audio API, and it spits out the unknown audio API specified error message. I think it's something to do with either my Xcode project's build settings or some issue with the defines. Is there a way to fix this?

Hans-Christoph Steiner wrote: Yay! Its my hope that we can build upon efforts like pd-devel and desiredata. Standing on the shoulders of giants kind of thing. I would like to contribute to a community fork that aims to be Pd compatible, but really focuses on decentralizing as much as possible, by structuring things around a very small core and everything else as libraries. I don't think we need a leader, I think we need to organize the code as a mirror of the community, which is quite decentralized. lovely. i think this could work very well, especially if we are able to keep what we are doing in sync with Miller's continuing work on the Pd core, making sure we merge in his changes as they come about, so that the community fork does not end up out of sync with vanilla. patches built with Pd-community should function correctly when opened with Pd-vanilla, for instance. the more i think about this approach, the more it makes sense... -- damian stewart | skype: damiansnz | [EMAIL PROTECTED] frey | live art with machines | http://www.frey.co.nz ___ Pd-dev mailing list Pd-dev@iem.at http://lists.puredata.info/listinfo/pd-dev

[PD-dev] ui development / desiredata?
hey, is desiredata still alive? i posted a couple of messages about trying to get an OSX version from SVN compiling a month or two ago and never got any replies.. otherwise, what's the status on UI development? if i was to just dive headfirst and try and fix some of the things that have been bugging me over the last week, is that at all useful or helpful? or is there someone i should talk to first? i haven't been involved in development of any open source projects before, and i guess i'm just not sure what the procedure normally is. in particular (i'm running Miller's 0.40-2 on OSX 10.4): - i'd like to bring in the multiple-level undo code from dd, or implement something similar - there seem to be some OSX-specific issues around sub-windows switching between PD windows - apple-` doesn't switch between PD sub-windows like it should. this could also be a Tcl/Tk issue. - there are consistent problems with populating the Window menu - the scrollbar down arrow is 95% hidden on the main Pd window, so scrolling messages down involves clicking a two-pixel-high strip, which is really hard - i'd like to put a scrollbar on the path preferences, so more than 10 lines can fit - mouse cursor alignment over the outlet 'plugs' on objects is bloody frustrating for new users (i've spent the week watching one) and it's just an offset issue i think - preserving newlines in comments! i don't know how possible this is (how tied comments are to Pd's core messaging system) but i'd love to be able to have multi-paragraph documentation with one comment object - occasionally when switching into a sub-window the mouse x offset is completely munted, so Tcl/Tk thinks the mouse is way over from where it should be - other things i can't think of right now i suppose what i'm really asking is - if i went ahead and spent a week fixing all the UI things that really bugged me, assuming my code wasn't really stupid or ugly or bad, what's the chances my changes would make it out into the world, and so be useful for people who aren't me? -- damian stewart | +351 967 797 263 | [EMAIL PROTECTED] frey | live art with machines | http://www.frey.co.nz ___ PD-dev mailing list PD-dev@iem.at http://lists.puredata.info/listinfo/pd-dev
