Re: [PD] patch wanted: loop station
NOt quite what you're after but Katja's SliceJockey is my favourite looping code for Pd http://www.katjaas.nl/slicejockey/slicejockey.html Certainly worth checking how she's done it. Yeah sooperlooper, I used to make use of that before Pd. It's good stuff.

I am still looking the archive / search engine to find a loop station in pd, but so far I found only basic implementation (no sync, no quantize, no cross-fade). I don't know the loop station. Can you elaborate a bit how quantize and sync work on? I think I understand how quantization works with MIDI, but with audio?

Secondly, the big thing for me is that this is really all about social-relations - how do I wish to be treated and how will I treat others. I could bang on and on but that's the big one. This is worth checking out http://texts.bleu255.com/preface-flossart/ as is the rest of the book which should be freely floating about online. (can't put my finger on it straight away but there was/is an online version which included all the books sources which was a nice touch) Bit of shameless self-promotion here too: http://eprints.hud.ac.uk/15006/ Regards, Julian On 10 February 2014 12:12, Simon Wise simonzw...@gmail.com wrote: On 10/02/14 20:27, Lorenzo Sutton wrote: Hi Pall, On 10/02/2014 04:45, Pall Thayer wrote: This was a faculty grant at a US arts-focused college. I would say that 95% of students, 80% of faculty use Apple products. That really doesn't matter though. As you asked for feedback.. I think it does. I'm not proposing the usual (sterile) apple vs. xyz flame, but I've noticed this mac for music thing in academia and conservatoires over here (Italy). One thing that surprised me is the attachment to this ecosystem in the electoacoustic music landscape, where one would expect people to experiment as much as possible with unknown and unfamiliar tools in all directions. What is also interesting is to understand if the use of Apple products and software (e.g. MAX/MSP) is truly justified by creative/artistic needs or if it's just a matter of habit/convenience (this question in a neutral way, i.e. nothing against convenience). 15 years ago editing video was very much better on a mac than any other comparably priced system, this certainly helped encourage many AV people to learn the mac way. While they still used powerPC chips there were a lot of advantages to OSX over linux for working with video in pd. A few good audio apps have been available on mac for a lot longer than that, and macs have been pretty consistently easy to set up for common audio workflows ... providing you stick with mac friendly hardware purchases and adapt your practice those workflows. Much earlier Apple had got a lot of designers on board in a similar way with desktop publishing. Learning to use an OS is a lot of invested time, changing OSes means a new investment of time. Apple understands this and has often made it quite cheap for educational institutions to get macs to teach on and has kept transitions between versions reasonably easy for the user, so a lot of students and artists with a bit of cash to throw at good equipment learn OSX, then go on to use it rather than learn another and when it comes time to pick a platform to teach on or recommend to others ... Habit and already invested time, plus decent equipment and effective tools available without changing OS are a quite persuasive combination. Now on a hand-held level apple hardware is again significantly better than other stuff for some media and audio uses. But you miss out on quite a lot too, and educational institutions should try to broaden their students' experience rather than just go with what is easiest. Simon I'm not sure how (much) this fits in the topic you're going to address, but I think it's an interesting angle to take into account. And I'll be happy to share my personal experiences further if you think it's interesting (as I guess my email was already rather long) Ciao, Lorenzo. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/ listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] Software Defined Radio in Pd
Hey all, I've come across something I'd like to share with everyone. Video demo http://newblankets.org/video/Software%20Defined%20Radio%20in%20Pd.webm (bit fuzzy but you'll get the drift) The patches are here: github: https://github.com/tkzic/pdsdr This from the github page: 'What is this? Here's a video of the basicSDR3.pd patch running with a soft66LC2 SDR: http://youtu.be/6sH6-DTU14E Patches are running PdExtended 0.43-4 on MacOS. Although you will probably find you can get it run in Pd vanilla with tweaks. The project is based on tutorial patches for the Max/MSP SDR project at: http://zerokidz.com/radio - They are documented at that site. Externals: The source code is kind of a disaster. Please don't ask how to compile. We just figured out how to get this running in Pd a few days ago.' Huge props to Tom Z for doing this. I spoke to Tom briefly last week and he said that he has no time due to work commitments to deal with this again for another month or so, so I think it would be better if we left him alone for a bit. There's a ton of stuff online to explain the concept further so for those interested I'd recommend some digging about. The creative potential for applications of this concept are vast (I'm still getting my head around it to be honest). He thought that it would be relatively trivial to turn the receiver into a transmitter which'd be pretty awesome. Even just making creative use of the endless variety of soundsources constantly transmitted unbeknownst to us is plenty for me to be getting on with. But yeah, what an ear-opener.

[PD] Free Impulse Response Software Update and Code Available
(A message [below] from my sponsor [well, supervisor]) Dear all I think this might be of interest to some of you. The PD port is stalled, but now that the code is public, let's make it happen ;-) pa == (and here's some info about the project) The HISSTools Impulse Response Toolkit, a set of Max objects to capture and manipulate impulse responses, is now available in version 1.1 at http://eprints.hud.ac.uk/14897/ Apart from a new object and few bug fixes, the major news is the support of both 32 bit and 64 bit versions of Max, on both platforms (MacOS and Windows). The externals are still SSE optimised and all other goodies. We are also releasing as promised all the source code under modified BSD license, available now at: https://github.com/HISSTools/HISSTools_Impulse_Response_Toolbox There is also a second video tutorial available, this time on electronic acoustic room correction https://vimeo.com/79202287 http://www.youtube.com/watch?v=QXOJWv3mvrc Finally, there was a presentation at IRCAM of the musical methodologies that were investigated so far within the project. These conclusions are available in a new paper available here: http://eprints.hud.ac.uk/18549/ We hope you will find good use of these resources. Alex and P.A. I was passed this info just before the new year but thought it would get lost amidst the general festivities and may also appear to be a bit, well, last year when we've all got our heads around getting back into stuff. (some background info) About a year or so ago Katja and I put out a call to the list and forum to see if there was any interested parties willing to help port these from Max to Pd. There wasn't, and that's fine of course. In the meantime Alex (Harker) P.A. have done a fairly sterling effort in separating the source code out into general dsp stuff and the Max specific, aiding greatly in any port attempt. My memory is that we had planned to at least port *something* from the library hoping that that may pique some interest in our community when people got some idea of the many creative possibilities opened up by having these objects available in Pd - but we haven't as of yet. To give some idea of the task as I see it: it took the four of us that ported one object ([ipoke~]) from Max to Pd almost 4 months of occasional work so to do this on a similar timescale - a decade! In fact this is a quote from Katja when I wrote to her after receiving the above email: HISSTools has all the elements a live performer can use to improve sound quality. As such it is a kind of 'standard work' that would ideally be available for every real time DSP framework. I am to an extent familiar with all topics covered (fft, fast convolution, filter inversion, minimum phase conversion). I know how to read and write C and had already expressed my interest to be involved in a Pd port. But because of the complexity I recoiled, and do not want to make commitments. It is way too much for a hobby programmer who incidentally writes a Pd external in free time. The port should probably be initiated by a professional, or an advanced DSP student, in the context of an institution like a university. Before even starting on the various classes the job would probably start with designing a cross-platform build system for the stuff. It makes no sense to use Xcode or Visual Studio for a Pd project. HISSTools has quite a few dependencies and should probably be done with an autotools build system (configure script, libtool, etc). It's a big job - no question. And if someone, who (for me) is one of the heaviest Pd coders I know, baulks at the sheer size of the task then I'm in no real position to be doing much more than cheering from the sidelines. Certainly I'm way too far down the post-grad line to be thinking of taking something like this on as a PhD type project but perhaps there's someone who may be interested? I will certainly do all I can to try and instigate some institutional support from Huddersfield (I think there's some recent post-grad fee-waiver opportunities for example) and I'm sure Prof P.A. (who can actually do something about it) would be keen. Or perhaps there is a possibility of a joint institutional project or something - I don't know really. Anyway - it's out there, it's probably doable, and there's nothing yet in Pd that does this kind of stuff in one nicely coded bundle. Perhaps we can at least discuss it amongst ourselves?

Hey, thanks! Here's another one: https://jwilkes.nfshost.com/self-discovery.webm Here the pony is spitting floats at her own source code. She can glitch herself and trigger automated behavior like firing in an endless loop. I just went ahead and disabled zero-logical-time recursive loops for the canvas forwardmess method responsible for sending the float the pony spits to an object. Forwarding a message like that is already obscure. I figure if someone really needs to use recursion on top of something like that it's probably time to start looking for a solution outside of a visual dataflow environment. -Jonathan Cheers, Chris. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/ listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] audio output AND input with the Rpi?
Hi Chris, I think Theron's covered most of it. The Behringer 222 is on the list of working devices compiled here: http://puredata.info/docs/raspberry-pi so hopefully that one should be doable, and my memory is that Andy Farnell has been running Turtle Beach cards during some of his workshops - stuck in my mind 'cos I had a Turtle Beach, old school chuckle to myself. If you do get them running (or not for that matter) it'd be great if you added your experience to the wiki page. For some more audio rpi tips and tweaks I heartily recommend this page: http://wiki.linuxaudio.org/wiki/raspberrypi and there's some more (related) good stuff here http://www.raspberrypi.org/phpBB3/viewtopic.php?p=286064#p286064 Plus of course there's a whole heap of stuff in the pd-list archives (search raspberry or rpi).

Also, there is a chance the issue might lie with Pd. I just don't know. I'm looking for a usb bus-powered audio interface for the Rpi that can take a stereo input and provide stereo output *at the same time.* * * I have tried a couple different images and a couple different audio interfaces, to no avail. Perhaps there's something can be done with one of these setups to get it working? First, the Pd-LA custom Raspian (v1) image and Pd 43.2: ..with Behringer UCA202 (at 44100khz): Alsamixer picks the device up but the input section shows nothing. Pd (gui) audio preferences allows selection of the interface for both input and output. Output only is lovely and clean but as soon as the device is selected for audio input the audio quality drops horrendously (vaguely recognisable from the original signal).. ..although what gives me hope is I CAN software monitor the input (poorly) in 'Test Audio and MIDI' with this arrangement. ..with Behringer UCA202 (at 48000khz): Output only in Pd is poor (beating and popping sound - possibly sounds like a samp rate conversion issue). When device is selected as Pd input software monitoring is possible and oddly, though the result is still poor, there is effectively no drop in quality from having the device selected only for output and the monitored signal sounds drastically better than at 44100khz. ..with Turtle Beach Amigo II* (at 44100): Alsamixer shows both input and output and allows to change gain of both. If plugged in from boot and only the output is selected in Pd it works but with a lot of jitter. Selecting the device for input too causes a further drop in audio quality although again I can software monitor the input in 'Test Audio and MIDI' If plugged in after boot the OS crashes. The Satellite CCRMA (operating via ssh) and Pd-extended: ..with Behringer UCA202 (at 44100 and 48000): Alsamixer picks the device up but again the input section shows nothing. If I have the device plugged in from boot then I get the same behaviour with it as I do in Pd vanilla on the Pd-LA Raspian image, ie. software input monitoring but at an extremely poor quality. If I don't plug the device in from boot I see it in Pd audio prefs but get this: ALSA input error (snd_pcm_open): No such file or directory ALSA output error (snd_pcm_open): No such file or directory from the Pd terminal and this ALSA lib pcm_hw.c:1401:(_snd_pcm_hw_open) Invalid value for card ALSA lib pcm_hw.c:1401:(_snd_pcm_hw_open) Invalid value for card oops: ALSA cards not reported in order? from the ssh terminal. ..with Turtle Beach Amigo II* (at 44100khz): Alsamixer shows both input and output and allows to change gain of both. If plugged in from boot and then only output selected in Pd I get clean audio out. If I try to select the Turtle Beach as audio inout in Pd then Pd stalls indefinitely when I try to 'Test Audio and MIDI' or make anything in

[PD] build pd with jack in raspbian on rpi?
Hi all, I'm attempting to build pd with jack in raspbian on rpi. I've got most recent pd from git. I'm following instructions from INSTALL.txt as I have a memory of IOhannes mentioning that's working again - and also it's the only way I know of adding the '--enable-jack' flag. Or so I thought: ./autogen.sh seems fine but ./configure --enable-jack Doesn't build pd with jack support. (outputs below) Any ideas anyone? Regards, Julian P.S.

Re: [PD] [PD-announce] Pure Data Patch Repository
Hey Patrick, Wonderful patch - much fun. No buffering here (Northern England with a fairly slow connection 8mg dl 512 ul) Debian/Iceweasel GUI seemed to lockup/stop_making_changes a couple of times but the freeze button seems to loosen it up again. I wasn't sure if what I'm hearing/seeing was just on my machine (local) so opened a couple of tabs with it and lo there's one master patch (this wasn't clear from your description).

Re: [PD] Preferences weirdness in Pd 43.1 ( 2?) in RPi
Hey Pierre, [import] isn't a vanilla object so may not be installed on the pi? I think it's in the repo's though. When you start as root it has it's own version of.pdsettings so the preferences will be different. To have matching settings between root and regular user just copy one of the .pdsettings to the other's home folder. Obviously not an ideal solution (ie dirty hack) but as long as your libs are in the search path [zexy/limiter~], for example, should always work.

I have to add their folders to the Path list. Note that the [import] object doesn't work either for these libraries. - when launching Pd as root, the preferences I set as a normal use don't load. This is a bit strange to me, and I have no idea how to tell Pd to use the same .pdsettings file in both situations.

Re: [PD] Raspberry Pi USB2 audio fixed (apparently)
Hey Pierre, I've installed Pd from the pre-compiled version of Millers site, and most recently built it from source which took a bit more doing but Miller very kindly walked me through the tricky bits (thread in archives installing Pd from source on rpi should bring it right up).

Hey Pierre, Not sure if the 2 are related but presuming they are... I've just been testing an ESI UDJ6 soundcard and the image I backed up before updating the firmware would only run the card with the usb and ethernet slowdown options. Post rpi-update got 6 channels of audio without either slowdown required though I think it does run better (less system resources) with both options enabled. My trusty ol' Griffin just 'works' with both installs so didn't notice any difference but I haven't yet checked whether usb slowdown is still required for duplex with that soundcard as of yet. This is on a rev1 256meg board btw.

Re: [PD] pyOSC receives but wont send/connect to Pd
Hi Matijoncek,
Thanks for your suggestion. Unfortunately it doesn't work.
Adding 'localhost to the .py file made no difference.
Also, the Pd receive patch has [udpreceive] which only takes the port
address as an argument.
Must admit that I'm now distracted by this post '[PD] Pd -- Python, IPC,
FUDI, pdreceive, et cetera !' which works here but is quite a lot more
involved. More steep learning curves.

The ground for the sensors is wired directly into the RPi. I'm not sure if this has happened after running the code for the sensors but I'm now unable to access the i2c busses: cat /dev/i2c* cat: /dev/i2c-0: Input/output error cat: /dev/i2c-1: Input/output error I note from the code that we're now using gpio17 instead of the i2c busses which would account for that error I guess? Few more coding issues but feel like we could do with some confirmation that the hardware's correct before moving on?

The clock line is switched using a 4051 analog multiplexer. The control line is GPIO_17 of the Pi connected to A of the 4051 (B, C and Inhibit are at 0V). 10k resistors to 3.3V are on each sensor's clock line at X0 and X1 of the 4051 (I2C clock connects to X). Because the code accesses the GPIO file system it needs to be run as root. I have two different sensors so the code reads two different packet lengths. Just a proof of concept, there could be up to 8 identical sensors on the same bus with this setup.

I have it in a breadboard right now, to make it more permanent I would solder a socket to a prototyping board then (after verifying the connections) plug the chip into the socket. Soldering to the pins makes it difficult to replace the IC, and risks damaging it with the heat if you're not good at soldering quickly and to the point.

Re: [PD] Sensors GPIO Raspberry Pi Pd
Hi Martin / all, Possibly overly-nerdy question here: I'm buying the various bits and pieces we require for the multiplexer and I'm noticing quite a difference in pricing options for the pull-up resistors. There's this one: http://uk.farnell.com/welwyn/rc55-10k-0-1/resistor-10k-250mw-0-1/dp/9499938 which is 86p each. Or there's something like this: http://uk.farnell.com/multicomp/mcf-0-25w-10k/resistor-10k-250mw-5/dp/9339060 which is 2p each. The former's spec sheet talks about its very low noise ratio and thinking on from reading the sensors spec sheet it's also pushed there to use low-noise components. Do you think it actually makes any difference? I have to buy a minimum 50 of the cheap ones so buying a couple of the dearer ones doesn't actually make much of a difference. It got me thinking as you mentioned that your getting virtually no PEC errors from the sensors whereas as we are getting them very regularly. I had been thinking it was the soldering of those pernickety sensors but could it also be the cheap 4k resistors currently on our board?

[PD] PCD8544 (Nokia 3110 and 5110 84×48 LCD) on Raspberry Pi
Hi all, Bit of an initial punt here: Before I dive into experimenting with the above lcd display does anyone have any experience with these and had it working with Pd? I've bought a rather nice readymade board for use with the RPi http://www.raspberrypi.org/phpBB3/viewtopic.php?f=59t=38204 and have the test python script working but currently that's about it. Spent several hours reading around the subject and weirdly python makes my brain hurt but C I'm very curious about and interested in (probably my latent thinking that 'proper' Pd'ers can handle a bit of C) but to engage directly with it in Pd somehow would be bloody marvellous. Although I've bought it for the Pi there seems to be lots of people hooking them up to an arduino so that made me think that maybe someone's already been here/done that. As per usual; any and all pointers gratefully accepted. Best wishes to all, Julian ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] Sensors GPIO Raspberry Pi Pd
I'm trying to think how this could be generalized into a useful Pd external but it seems very specific to a particular setup. I do think a more general [i2c] object would be super-useful. Particularly if it could directly open up and access the i2c line. Not sure how he does it but wiringPi has some kind of test routine that figures out what rev board it's on, which is pretty nifty too. If there's a method to incorporate the i2cdetect functions as well then it would be a one-stop-shop - so to speak. Maybe an additional object to [gpio], plus the 2 omron's as externals / or combined into one and that's definitely the start of a new bad-ass lib:) OAN - Really impressed with the C program: the drain on system resources is very minimal. I'm still getting PEC errors on a regular basis though I still think we may have a dodgy connection somewhere down the line - sometimes when i2cdetect the sensor isn't registering and need to give it a little wiggle (not ideal). Also presuming that as the clock is running at 10 cycles that the readings being passed to Pd are set here: char netbuf[256]; in the C code? (could be talking out of my rear-end here I know) And I'm also presuming they can be edited in those multiples (128, 512 etc)? I haven't started experimenting yet but the plan is to run the installation headless. Is there anything I'll need to change in the code to allow the C program to run from boot: Like at the moment the readings are being spat out in the xterm (stdout) via 'printf' I think, which is also replicated via the [netreceive] patch, so I'm guessing I can start to trim stuff down. Thinking aloud here - what I think would be really useful would be a method to have everything start at boot and then a method to route vital test info from both Pd and the C program to one shell so I could ethernet/wireless in via my lappy to check that all is well with the piece. My leaky memory thinks that there's also a fairly recent workaround for the Pi (for M.E.Grimm I think) with routing pretty much this kind of stuff. Anyways, thoughts starting to wander, back to it:) J On 23 April 2013 14:45, Martin Peach martin.pe...@sympatico.ca wrote: Yes that would work too, if you can handle the soldering ;( I suppose you could modify the c code to run two sensors and send the data to two different port numbers, or use two different selectors for the message.

It only needs to be as large as the message, I made it too long to be sure it wouldn't cause trouble. The length doesn't need to be a multiple of anything. I haven't started experimenting yet but the plan is to run the installation headless. Is there anything I'll need to change in the code to allow the C program to run from boot: Like at the moment the readings are being spat out in the xterm (stdout) via 'printf' I think, which is also replicated via the [netreceive] patch, so I'm guessing I can start to trim stuff down. You can comment out any lines with 'printf' in them by prefixing a double slash //. I have been running it headless via ssh as: nohup ./d6treader 0 /dev/null This sends all the text output to nowhere and also keeps the program running after I close the connection. (I had it running for a day without redirecting output and it nearly filled up the sd card.)

And also are you attaching the MC14051 to any type of board/adaptor or just soldering straight on to the pins? I have it in a breadboard right now, to make it more permanent I would solder a socket to a prototyping board then (after verifying the connections) plug the chip into the socket. Soldering to the pins makes it difficult to replace the IC, and risks damaging it with the heat if you're not good at soldering quickly and to the point. A CD4051 would also work, it's basically the same circuit. Martin ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Hey Martin / all, Omron tech support finally got back to me re the address issue, this is what they had to say: D6T sensor can not change the address. When you connect multiple sensors we recommend that you use the IC switching. Please refer to the below document. http://media.digikey.com/pdf/Data%20Sheets/Omron%20PDFs/D6T44L_8L_Appl_Note.pdf I've been through the spec sheet several times and don't see anything (admittedly not sure exactly what I'm looking for though) that relates to IC switching. We've still got 2 of these doing nothing currently if they could be brought into action: http://adafruit.com/products/757 Or people on the RPi forum seem to have got the 2nd i2c pins going but that seems to be for rev.2 boards only (I think - have posted a question on the thread to ask). Also asked tech support about the PEC errors but no response to that one. I've noticed that the PEC doesn't trigger errors all the time so am wondering if it's possible to filter the errors out of the data somehow in the C file? Still delighted though - the sensors great!

Re: [PD] Sensors GPIO Raspberry Pi Pd
and there's a document there that has something about using multiple sensors on one bus: http://www.mouser.com/catalog/specsheets/D6T-01_ThermalIRSensor-Whitepaper.pdf That's a much better doc. Seems to me the easiest way to multiplex them would be to put a CD4051 on the clock line and use up to 3 GPIO pins to select which of up to 8 sensors receives the clock. The only tricky bit would be making sure the clock is at the right level when the switching tales place, you might need ~10k pullups to 3.3V on the sensor clock pins. (did you spot my previous post with this and if so would that work?) Yes that's what happens already. I was getting errors at first because the crc calculation was being done over both the write and read packets. I found that calculating only the read packet gives the correct value almost always. If the PEC is wrong, the code simply asks for another packet. At the moment I'm getting almost no errors Maybe there's something I'm missing here then: The average temp that comes out of [unpack 1] is way higher than the rest of the readings. At the moment [unpack 1] says '212' yet a quick averaging of the other 16 readings is around '180'? Yes, it even works as an icecube detector! :D ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Don't think this is possible with the rev1 board - I do have a rev2 so might have to jump ship, though my super minimal image has some networking issues - I can't get it to ssh and register on home network with fixed ip on rev2 (must be sortable). Another way would be to have the Pd patch request a reading from a specific sensor. Can we do that if they have the same address? I'm trying to think how this could be generalized into a useful Pd external but it seems very specific to a particular setup. Yep - it is very specific, bloody good tho'.

It’s not working! We spent the day soldering cables and connecting stuff up as per the Omron ‘App Note 01’ spec sheet. Started off super-conservative using the I2C level converter (case 3 page 4) http://www.adafruit.com/products/757#Blog/Flickr We tried resistors on both sides (being super paranoid!) and then we took the low (Pi) side ones off. We then moved on to case 2 page 3 of this same document… At each stage we checked with “I2Cdetect –Y 1” and nothing was visible. The grid shows no attached devices every time we run it. We re-booted at every stage following the various online tutorials/methods of setting up I2C GPIO on the Pi (checked double checked). As you can see we’re using a pi protoplate: https://www.adafruit.com/products/801 In the photo I’ve attached the cables are coded as follows: Orange GND Yellow5v BlueSCL Green SDA The white is also 5v for the pull up resistors. The resistor values are 4.7k btw. We have tested the cable that terminates at the sensor and all that is OK. I put a multimeter on the GND and SDA solder points on the sensor itself and got 3.7v… I put a multimeter on the GND and SCL solder points on the sensor itself and got 0.0v… Don’t know if this means anything or could be useful to know! Stuck and frustrated now but hey, 3 weeks ago I knew absolutely bugger all about any of this and now I do (sort of). I'm thinking we could do with the most basic i2c sensor we can find as we have nothing to compare. Tonight I'm going to d/l a fresh raspbian and start from scratch to check that end. Feel like if we can't get past the 'i2c-tools' tests we're screwed - never mind getting it in and out of Pd. Any thoughts/pointers/options from anyone will be really appreciated? Cheers
[PD] [gpio] i2c bi-directionality
Hey all, It seems, and please correct me if I'm wrong on this, that it's currently impossible to use[gpio] and i2c as [gpio] can only set the gpio pins to 'in' or 'out' (high/low). You can check this using wiringpi's 'gpio readall' command which gives the current mode of each pin. Via [gpio] we can currently set the gpio pin 0 (SDA) to either 'out' (low) or 'in' (high) but not to ALT0 (high) which is what we need for i2c as the i2c line is bi-directional. My understanding is that [gpio] is based on wiringpi so is it possible/trivial to add i2c support into [gpio] with the magic ALT mode? I wrote to the author of wiringpi to ask what the ALT0 mode meant (I actually thought it was ALTO) and got this response: Each pin has a number of modes it can be in – Input or output are generic digital modes – then there are ALTernative modes – up to 6 alternative modes for each pin – ALT0 through ALT5. For I2C mode the internal plumbing connects the pins to the I2C drivers – this is ALT0 mode for that particular pin.

Re: [PD] gpio on the raspberry pi from within pd ?
Morning Jaime, Nice digging - well done. As I don't read C I admit to being somewhat at sea with the possibilities of the object so really good to hear someone else is rooting around in this. I did manage to get access to the GPIO pins making use of the messages that Charles mentioned: sudo bash echo 1 /sys/class/gpio/export echo out /sys/class/gpio/gpio1/direction chown pi /sys/class/gpio/gpio1/value But really good to just do it from within Pd - how'd you get round the sudo-thing? Not sure what it is you're doing project-wise with the GPIO pins but I've spent a couple of weeks digging through the somewhat endless bits and pieces of documentation on the web so perhaps I could be of assistance with some pointers on that front? Most of the info/code is Python-based and there's plenty of it (I'm also a complete noob re Python as well!) Miller and Charles were certainly on the right track with WiringPi as I would say it's easily the most referenced library. . My own interest is with getting a fairly recent i2c thermal imaging sensor going (see other thread) and Martin Peach is giving us some invaluable help with that but it would be my ideal scenario to be able to control, manage and filter the sensors data from within Pd (once we get the thing going!). My understanding from reading Miller's initial message re [gpio] is that it's based on WiringPi so I can't help wondering if there's also a method to include the i2c library that's a subset of WiringPi as well? Would be super-useful. Obviously early days yet but I'm sure we can get there eventually.

It works fine, but there there is no documentation, however, the .c file is not very complicated. The test-gpio.pd file is not very good as documentation, so I am attaching a draft help file. The argument of [gpio] is the pin number. The first thing to do is [enable 1( and not [open 1(, which is equivalent to the: sudo echo 17 /sys/class/gpio/export command. Then [open 1(, then [output 1/0( to choose direction and then write (float) to or read (bang) from the pin...

Re: [PD] Sensors GPIO Raspberry Pi Pd
Hey Martin / list, This is all marvellous news. Going a bit slower at our end, not helped by Easter holidays, trips to the seaside (bit chilly) and the plethora of children that require our undivided attention. ebay parts arrived today and don't fit which is annoying to say the least. Spent several hours tracking down the correct housings and pins and then finding somewhere in the U.K. that would sell me less than a hundred housings or a thousand pins. Ended up with 5 and a 100 respectively. Also got a voltage transformer that works with i2c as the rpi is 3.5v and sensors 5v. Am planning on blogging all the info when done but if anyone wants any specifics before then please say. I'm slowly making some headway with getting my head around the gpio pins and setting those up to use with Miller's [gpio]. I can now access the i2c pins via [gpio] and send them 1 or 0 setting the pins hi and lo which is a start. Also found where to set the baud rate from within the RPi which will be useful. Although the sensor mentions 1000k as baud rate I'm thinking that 9600 would be better for overhead reasons. Perhaps we should get it working as is before starting to change too many settings? Still absolutely no idea how to setup sending and receiving 16b messages plus how to add in the delay but we *will* get there in the end. You write the value 0x4C (76) to address 7 and then request 32 (35) bytes, which are 16 little-endian integers. Any ideas how we would go about formulating messages for this from within Pd? Should we be looking at [comport] at all? I've found this to be the most informative info for the d6t so far: http://media.digikey.com/pdf/Data%20Sheets/Omron%20PDFs/D6T44L_8L_Appl_Note.pdf With my limited understanding it seems to be saying it's big-endian (msb first, p.4) ? We have 2 sensors so we need to figure out how to set the 7bit addresses. Also that the data bit width is 8 - so I'm confused as to what the 35 bytes are and where they come from? Obviously things should become clearer when we actually have the sensors connected and we can then see what they spit out (if anything) but it can't hurt to try and head off some of the more obvious questions I have now. Like, will the data from the sensor appear at the outlet of [gpio]? The same author of *WiringPi* also has the i2c-library - would it be possible to fold this into [gpio]? Questions questions...

Yes I meant [comport] with the xbee rather than [hid] sorry, getting my physical input objects confused. Will check out the links you provided as part of my getting up to speed. So, managed to get the sensors out of the cardboard box. They are tiny. Like little sci-fi robot eyes. 1st problem is that we don't have any of these: 'JST (Japan Solderless Terminals) - PHR-4 - Housing, 4way, 2mm http://uk.farnell.com/jst-**japan-solderless-terminals/** phr-4/housing-4way-2mm/dp/**3616204http://uk.farnell.com/jst-japan-solderless-terminals/phr-4/housing-4way-2mm/dp/3616204 Which is a vital £0.04.6 of equipment as the sensors pins are way too tiny to be poking bits of wire into. These attach to the bottom of the board and then 2mm cabling attaches to them and out to the Pi. Got some off ebay as farnell has a £20 minimum spend that's a bit over getting 10 of those suckers. So going to have to wait a few more days as I can't find any in my vicinity at all. Bollocks. Yes I got mine at Digikey. You need the terminals as well as the housings. I crimped the terminals to some 28 gauge wire and also put a bit of solder but not too much to plug them up. Today I managed to get data using an Arduino and the Wire library, with 4.7k pullup resistors on the clock and data lines. The packets are only 32 bytes, not 35 as the app note says. Not sure what's up with that. I changed the default buffer size in Arduino's wire library from 32 and now I get 35 bytes as advertised. The crc calculation is not giving me the right answer but that doesn't seem to matter. I get 16 pixels of temperature, it's detecting warm as well as cold objects, quite a nifty sensor!

Re: [PD] Sensors GPIO Raspberry Pi Pd
Thanks Martin, really useful stuff. I've got i2cdetect on the RPi which is how I knew that [gpio] was setting hi lo. And good to hear you'll be wrestling with this on the Pi as well. In some ways this is good news as we've setup everything from the 'instructables' page already and now just need to get the bloody thing going (have to to sort the housings out). Another possible issue is that from my reading it seems that the RPi doesn't do 'clock-stretching', though I have found a link where they slow the i2c bus down. http://www.hobbytronics.co.uk/raspberry-pi-i2c-clock-stretching Another one here too: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=44t=34734p=294297hilit=i2c+gpio+direction#p294297 That's interesting as they talk about setting up more GPIO pins for i2c to run 2 sensors. Not being able to change the sensors address is a real pain though, as one of the things that I keep reading about i2c is it's ability to run up to 128 sensors on the same line - kinda defeats the object! Must be a way round it. You can use the 5V from the GPIO header on the pi. From the schematic pin 2 is 5V. Ground is on pin 6. Pin 3 is the i2c data and pin 5 is the clock. Pullup resistors are already installed on those lines. Yes, found a good diagram for the GPIO schematic. http://elinux.org/RPi_Low-level_peripherals#GPIO_hardware_hacking My understanding was that what we can't do is send data from the sensor at 5v back into the RPi at 3.5v and it's there that we need to drop the voltage back to 3.5. Noticeably though the 'instructables' link says they just did it anyway and was fine (with a disclaimer attached on to it). We got some 4.7k resistors as you recommended - do we only need these before the sensors? The pdf from digikey has a diagram with a voltage transformer that we've been presuming is what we need to do?? Presumably if we put more resistors next to the Pi then we wont have enough voltage to lift the pin high (many ???). There's also lots of code (C?) on that pdf, anything you've made use of? This is the little add-on board http://adafruit.com/products/757 I did read it's doable with mos-fet but seemed like another layer where we can screw-up so have taken the simple option. Still don't get how we tie in the clock and the messages but I'm sure it'll become clearer when we actually get to the point where we can start it up.

Re: [PD] gpio on the raspberry pi from within pd ?
Hi Charles / list, Can I ask you/anyone a question re: permissions for accessing the gpio pins please? Currently I can't get past: echo gpio17 /sys/class/gpio/export which gives me permission denied with everything I've tried. Are you using WiringPi to allow access to the gpio and if not how? I'd like to stick with Miller's [gpio] object http://crca.ucsd.edu/~msp/syllabi/206.13w/index.htm (found in the earlier split thread - apologies for the noise) and keep as much within Pd as possible.

I use it to drive a light system from a track of a audio file containing only square waves at a given frequency (say, cues embedded inside an audio file). I basically snapshot~ and see if it's over or below 0, and turn the gpio on/off on change. I started using pd on the pi three hours ago and have it playing audio and banging the gpio in no time.
