[PD] Sensors GPIO Raspberry Pi Pd
Hi all, We've been after some sensors for motion detection on the RPi and Martin Peach spotted these (thanks again Martin!) http://uk.farnell.com/omron-electronic-components/d6t-44l-06/sensor-thermal-mems-4x4/dp/2218000 They're fairly new and I've not been able to find anything about anyone making use of them on the RPi as of yet (though after posting a question on the RPi forum I did note that Farnells stock went from 48 the 4 in three days, so maybe something soon eh?:). I've got absolutely no idea what I'm doing with this so could do with some 'hand-holding'. What I would much prefer would be to keep everything within Pd if possible... 1st off, and possibly dumb question - do we need [hid]? - My previous experience with xbee sensors did, so this is why I'm asking. There are a few mentions of using python to get the data received on the Pi and then OSC'ing that into Pd but Miller mentioned on another thread gpio on the raspberry pi from within pd ? about writing an external to keep it within Pd. Any news/progress/tips on that front? In the same thread Charles Goyard seems to have it working with [textfile], which seems far too simple (I'd very much like that if that was the case) The sensor transmits the data as i2c but I haven't found anything in the archives particularly about anyone translating i2c directly in Pd yet? We're going to fire the sensors up and see what happens in an hour or so and then come back to it tonight for a proper session so any and all pointers gratefully accepted. I'll be back to let you know our 1st results soon. Cheers, Julian ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] [ANN] New External: tglgrid, a togglable grid of cells
Posting here too since I got a lot of silence on pd-dev. From the README: A tglgrid is a grid of cells that can each be toggled on and off. It can be instantiated with different dimensions depending on your project's needs. You can bang the left input to output a list of the active cells in the currently active column and send a column number to the right input to select the active column. Cells can also be toggled and/or turned on/off by sending messages: tgl col row, on col row, or off col row. Right now this has only been tested on linux. I would appreciate any reports about success and/or failure of running this in other environments. The github page is here: https://github.com/nicklan/tglgrid You can find screenshots there if you're interested. As this is my first external, I'm sure I've made some horrible coding/design mistakes and appreciate any feedback in that regard. Cheers! -Nick ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] [ANN] New External: tglgrid, a togglable grid of cells
Hi, sound great, thanks for sharing ! Here are some features request that come to mind: - add the possibility to work by row and not by column. It can be another object, such as rtglgrid, or a creation argument (tglgrid 10 10 byrow). - add a say col row message that returns a single cell state. - before someone else asks: dynamic resize of the matrix :) Happy hacking :) -- Charles Nick Lanham wrote: Posting here too since I got a lot of silence on pd-dev.

I just got one of these and I'm going to try it with an arduino since the i2c there is easier to use. The arduino can talk to Pd using [comport].

[PD] Reading multiplexed data from an Arduino
I'm trying to use two multiplexers, one with 16 potentiometers and the other with 16 buttons, to read the data in Pd. The potentiometers work fine, but I get nothing from the buttons. Wiring look correct (I've tried it with a single button and it works), so I've no idea what goes wrong. I've attached the Arduino sketch and the Pd patch if anyone's willing to give it a look.

Re: [PD] [ANN] New External: tglgrid, a togglable grid of cells
This is really nice. I like the red highlighting when you hover over a square. Very clean and useful. I'd give a +1 to adding a [get row x( method, as well as [get row col( for a single cell.

Re: [PD] [ANN] New External: tglgrid, a togglable grid of cells
Looks quite nice! One thing that might make your Tcl-side development easier is to put all the Tcl code into a tglgrid.tcl file and load that in the setup() function. The template Makefile will automatically handle that file for you. You can see an example of that in hcs/cursor.c: http://pure-data.svn.sourceforge.net/viewvc/pure-data/trunk/externals/hcs/cursor.c?view=markup http://pure-data.svn.sourceforge.net/viewvc/pure-data/trunk/externals/hcs/cursor.tcl?view=markup Then you can also better manage redraws within the Tk event loop using the [after idle [after 0]] hack: http://wiki.tcl.tk/9926 .hc On 03/27/2013 05:34 AM, Nick Lanham wrote: Posting here too since I got a lot of silence on pd-dev.

Re: [PD] Sensors GPIO Raspberry Pi Pd
Hey Martin, Good to hear you've got one of these too. 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/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. We did put our pi prototype/breadboard together though: http://www.coolcomponents.co.uk/catalog/raspberry-proto-plate-p-1104.html which will be useful for experimenting. Off to gen up on i2c, python and other such things I currently know nothing about. Back soon with further info.

Re: [PD] the next PdCon in...
Golan Levin and Dan Wilcox are the people at CMU that would be the organizers. From what I've heard, they are interested in doing something, but probably a smaller version, and tied to the VIA art festival, so the dates would only be Oct 1-5: http://www.via-pgh.com/ So we should decide whether that sounds workable, or whether we should just focus all efforts on getting a full pdcon next year. .hc On 03/26/2013 10:33 AM, Epic Jefferson wrote: No answer?!

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. You write the value 0x4C (76) to address 7 and then request 32 bytes, which are 16 little-endian integers. The numbers are in tenths of a degree Celsius. I needed a 1 or 2ms delay between sending the command and requesting the data or the sensor would stop responding after 3 packets.
