My understanding, and I'd be happy to be proved wrong, is that they are either 'on' or 'off', motion or no-motion. And this case what we'd really like is to be able to detect motion but also depth (3d) so we can measure whether something is moving towards and away from the chimes with a proportional representation of force. Then ideally lateral movement too so, say, someone waves their arm from side to side that that could also be measured. Tricky challenging on such a lightweight machine, particularly with no GEM, but I guess that's also part of the fun:) Many thanks for your suggestion though.

Re: [PD] bi-directional OSC over TCP from liblo
If you look inside [unpackOSCstream] you'll see that it uses [slipdec]. So the other end must be using [slipenc] or they won't match up.

Re: [PD] Retrieving data directly into PD from HC-SR04 sensors connected to Arduino
It would be easier if you sent only the integer value:

Serial.write(microsec, sizeof(long));
delay(400);
}
And in Pd collect groups of four characters from [comport] and reassemble them

Easiest is to send only a single byte per sensor. But you'll also need a way to
determine which is the first character in the packet.

Re: [PD] no pd?? WTF ????
I think Pd uses %g which probably means %.6g by default, but it looks more like %.5g. You're right, the precision is only lost when the patcher is written out somewhere. In the attached patcher clicking on [1( calculates pi, which gets printed to a number box and the screen in 5 digit precision as 3.14159, but the subsequent [sin] object gives a value much closer to zero than when you click on [3.14159(, so the numbber box is hiding some extra precision. Martin But whatever the theoretical precision of a float, I think the thing that makes Pd floats less precise than Max floats lies in the use of the %g format specifier to print them out, which can result in a lower precision than the float is capable of. The %g specifier is able to print at full precision, if you instruct it to, but pd only uses something like %.6g, whereas you'd need %.8g to conserve all the binary precision (%.7g is slightly not enough, %.8g is too much, but there's not a %.7½g). To conserve the decimal precision, however, you flip it around : in a 32-bit float, you can only load a %.7g without loss, and a %.8g won't fit. But this only applies if the data really has %.8g precision to start with, which is not the case with %.8g numbers that came from float32, which really have only 7.2247 decimals of precision, which fits exactly in float32. This makes it possible to use maximum precision float calculations inside of objects but not between them. Between two objects communicating by float messages from outlet to inlet, things happen only in binary, and you already know that. This means that you can have 24-bit float32 precision between objects. The drop to 19.93 bits of precision (%.6g) occurs only when converting to decimal ascii text and back.

The disaster would be if Pd tried to guess what the user intends based on some general idea of what Pd is 'for'. For instance I've been working on an xbee external where I need to specify numbers like 0x0a060123 for the remote address. I do that by interpreting the symbol as a 64-bit integer internally but I would not expect any other external to do this unless it needs to. Otherwise the user would have to manually convert the number (which is conventionally given in hexadecimal form) into a bunch of decimal numbers small enough to be represented as float and then the external would combine them internally.

Re: [PD] netsend/netreceive + GUI bug
hmm, i don't know where you get this idea from, but to me, the code of Pd's networking infrastructure looks, as if a) all incoming traffic was polled for in the main thread b) all output of this traffic (to the Pd-patch) was propery protected by sys_lock() I am honestly not that familiar with this low-level aspect of pd. What I am however aware of is that the poll function responsible for receiving message (meaning when it arrives at the socket) inside netreceive immediately dispatches it to pd and its polling is linked not to pd's main loop but to the moment when the socket has received a packet which appears to be a part of any basic network socket example code available online and as far as I can see, I did not notice any relationship between its polling intervals and Pd's main loop. If you are indeed talking about vanilla netsend and netreceive, the poll function is called during pd's main loop, not when something arrives at the socket. In x_net.c : sys_addpollfn(sockfd, (t_fdpollfn)socketreceiver_read, y); socketreceiver_read is in s_inter.c: void socketreceiver_read(t_socketreceiver *x, int fd) sys_addpollfunction schedules the function to be called each pass through Pd's main loop.

I'm following the text here: http://puredata.info/docs/developer/BuildingPdExtended So I do this: cd pure-data/packages/linux_make make install ...and the build ends in pd/src: dbtopow~.c:5:20: error: e_sqrt.h: No such file or directory. It's true there is no e_sqrt.h in trunk/pd/src. Which repository should I be using here?

So we´ve to compare PD with Max and then will decide for the better one... I prefer PD, so i need some Arguments for PD... Why PD and non Max? My Arguments are: * In PD you can easily write own Objects in PD (With C/C++ -- Is that in Max as possible like in PD ??? Yes, see: http://cycling74.com/products/sdk/ Apart from that, Pd is free and also runs on linux.

Re: [PD] hardware implementation of [*~]
You're looking for a balanced modulator. The MC1496 is one. The original ring modulator used a ring of 4 diodes between two transformers. Running two pulse waves into an AND gate will give a binary version. Martin Hello all, So I'm getting my feet wet in digital circuitry this quarter at my university and I've got numerous projects I want to waste my time on, one of them being a simple ring mod effect in the same vein as the ring mod found here: http://en.flossmanuals.net/PureData/AmplitudeModulation My question is what would be the hardware equivalent of the [*~] object. I guess it don't have to be digital... even an analog equivalent would help me understand it better. Hope this question makes sense, I don't have a good grasp on the terminology in this field one bit.

Re: [PD] [PD-dev] odd key object behavior under Linux
It probably happens when you get two keydowns in the space of one Pd event loop. The second is output at the same time. The same thing happens with [metro] banging serial data into [comport] or [midiout]. The metro rate is quantized to the event loop rate, so individual bangs are irregularly spaced but the mean time over many bangs is perfect. The only way to get perfect timing is to use signals, messages are always handled after the sound has been computed. So if you don't like it you could slow down your keyboard repeat rate to slower than Pd, or use a microphone to detect the keypresses ;) Martin Ico wrote: It all started when I noticed that my threaded version of coll object tended to freeze Pd at apparently random points.

Re: [PD] [PD-dev] odd key object behavior under Linux
Yes, the OS also has its own event loop, which might be more responsible for that kind of timing, as it isn't running at a fixed rate and keyboard is probably a lower priority than mouse or network events. Martin Ico wrote: Many thanks for the explanation! What seems weird, however, is how divergent time delta between repeats is. On Windows it is always around 30ms (at least on my hardware) whereas on Linux it goes between 0, including 1.4ms and up to 50+. Even when accounting for jitter between two events I cannot imagine that they oscillate that much (unless my flavor of kernel/hardware treats keypress timing like a dirt :-).

Re: [PD] exact meaning of netsend outlet
wondering what the exact meaning of the outlet of [netreceive] in TCP mode is: Does it indicate whether Pd through the OS was able to open a port The right outlet indicates that the port is open and the other end is listening. or does it indicate if a TCP packet arrived at the destination? And: Am I correct assuming that netsend only outputs a message when it got a (send ...) message into its inlet? So there is no way to indicate whether the receiving machine is online unless I keep sending heartbeat/ping messages? If the other end drops the connection, then the right outlet will output zero, but it might not happen right away. Especially with wireless it's better to have some kind of heartbeat ping-pong going at a higher level than the OS.

Re: [PD] OSCSerial for windows
Hi Ricardo, Well I didn't have chance to try it with [comport], but I suspect you need to make the output of [comport] into lists using the slip packet delimiter 192 and [list append] and [list prepend] as in the [list] examples. It should not crash Pd though, that's bad... Martin Hi Martin, I used [list preped] and [list append] as you said and now it works, thanks. Yes, but I think it should work with individual input bytes, I noticed that it's not checking the buffer for overflow in that case, so I will fix that today. I was getting crashes by feeding [slipdec] with random bytes. However, I am still getting crashes with the stream from comport (if I program the microcontroller to send messages every ~200ms, it works fine), I read a recent mail about unpackOSC, then I tested using just slipdec (still crashes) Crashes occur if I send messages too fast, just putting a [metro 50] to a valid message in slipenc-help.pd or sending microcontroller messages every 10 - 50 ms, freezes pd, and eventually make it crash. Maybe it's a [print] object overloading? Trying to print thousands of numbers usually hangs Pd. I don't know what should be the minimun time that slipdec needs to process a packet, I use the same settings that I use in Linux with serialIO, OpenSoundControl and OSCruote [1], in Linux it works pretty well even with shortes times. It should be able to hold on to a partial message indefinitely, but at the moment if the message list isn't a complete SLIP packet it might not work properly.

Re: [PD] question about netclient and netserver
reduzierer wrote: From what I know, there is an internal buffer of ~4kB for the sending sockets in both netclient and netserver (I can't recall whether this buffer is built into the externals or is part of the network subsystem of the OS). If that limit is hit, the Pd process is blocked until that buffer is emptied again (which leads obviously to audio drop-outs). IMHO, this is a design flaw, which all sending net-externals suffer from. There is no way to check the state of this buffer, which would be required in order to avoid a buffer overrun. It would be sufficient to get notified only, when the buffer is completely emptied, so that you could design your patch in a way that it would only send the next message when the previous one is through. IMHO it's not a design flaw, but part of TCP's design philosophy that tries to send packets until they are received. In the original concept, bombs would be dropping all over the countryside, destroying cables and data centres willy-nilly, while messages could still get through to the missile silos and AA gunners. UDP was designed to send and forget. If you are broadcasting in TCP you are actually sending separate messages to each recipient, with the OS providing overhead for each one until it has been acknowledged by the recipient. Obviously it's easy to do a DOS attack this way even on your own machine simply by sending faster than the receiver can process the packets. Broadcasting in UDP sends a single packet to a single address that the router sends to every machine on the subnet. The OS discards the buffer as soon as it is sent, so you can't overload the stack, although you can always peg the CPU trying.

Re: [PD] arduino problem with analog sensors
The microcontroller in the Arduino has a single sampling capacitor that can be connected to any one of the analog pins. It will charge up to the voltage on the pin if enough charged particles are available on the pin (or a path less than about 10kohm exists to a source of current). The cap is not discharged by the analog-to-digital conversion process or between samples except through leakage. If no charge is available on the pin the capacitor will continue to slowly drain its charge from the previous sample. It's normal and harmless unless you are in a high-voltage environment like a thunderstorm or a nylon carpet, where much more than 5V could accumulate on an open pin. Then it's best to ground unused inputs.

Many arduino users would be very happy. Is this on linux? It should be non-blocking on Windows. I suppose it crashes only when you try to send something, not if you just pull the cable out. I would have thought that if hardware handshaking was off, the port will send anyway. I seem to remember sending into an oscilloscope probe with no cable present. Select is problematic, as we have seen with recent [tcpserver], checking if each byte can be sent before it goes out slows the whole thing down a lot. i am still in the process of understanding things, that you have to deal with, so forgive any obvious question from my side, but why is it necessary to call select() for each single byte? wouldn't it be sufficient to call it 'from time to time' (whatever that means)? I guess if you pull the cable out at the exact moment that [tcpserver] is sending a message, every once in a while it might hang because select said it was clear to send, but right after that the connection broke... just out of curiosity: if there is a solution, that works well for [tcpserver], couldn't it be applied also to [comport]? Maybe. But I think you should be able to use [comport] with no hardware handshaking enabled and send data even if no cable is attached. Sometimes the absence of one of the two input handshake signals prevents the serial hardware from sending. Also if an error occurred in the reception of serial data it may not be handled properly in [comport].

It's not pd's problem if there exist more than one file with the same name. Surely that's up to the creators of the files to sort out. The alternative of using paths for each and every object is a massive kludge that's going to fall on your head and crush you sooner or later, at least I can already feel it pushing me into the mud :( [possibly/the/worst/idea/ever/invented/once] Martin ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] object or class in pdpedia
Class is what pd calls objects internally.
For example here is the setup routine for the unpackOSC object:
void unpackOSC_setup(void)
{
unpackOSC_class = class_new(gensym(unpackOSC),
(t_newmethod)unpackOSC_new, (t_method)unpackOSC_free,
sizeof(t_unpackOSC), 0, 0);
class_addlist(unpackOSC_class, (t_method)unpackOSC_list);
}
I think of the ideal thing as a 'class' and its instances in a patch as
'objects'. The object receives 'messages' that the class handles using
'methods'.

I think the current usage of the term object in Pd has two meanings:
an instance of a class, and the class itself. I think we should
distinguish between these two in the pd wiki, and the word class is
quite well established for that.
Yes, that means some education for some users, but that's a big part of
the pdpedia mission.
That's my take, Marius will now disagree. :D

Is this a potential memory leak, or is there a cap to how much memory it will hold? A float always uses 4 bytes. When the number gets too big, mod won't work properly because the number it's working on won't be accurate. It won't ever use any more memory.

Maybe someone can dumb it down for me? You can only work with atoms in pd's message system, and each atom usually contains a bang, a float or a symbol. You could convert the pointer to a float but it probably won't work because the pointer is a large integer that won't be accurately represented as a float. You could convert the pointer to a symbol using something like: char symstr[10]; t_symbol sym; sprintf(symstr, %p, frame); sym = gensym(symstr); ...then send sym through the outlet and convert it back to a pointer at the receiving end by extracting the string from the s_name field of the symbol and passing it to atol().

So if you add e.g. /usr/local/lib/pd/extra/iemmatrix, it will search for this path, but local to the canvas path - so if I started Pd from /home/me it will search in /home/me//usr/local/lib/pd/extra/iemmatrix ! Is this a feature or a bug of Pd ? I would say it's a bug: I would expect that if the first character of the path is a slash, it's an absolute address, otherwise it's relative to the canvas path. So /usr/local is absolute but usr/local is relative to the canvas path. In Windows there's also the problem of specifying drives as in C:/pd, so it's necessary to look for a letter followed by a colon followed by a slash in the first three characters of the path. And then there's double slashes for networked drives... Martin ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

It's just named rlshift~ instead. Else it should work fine (unless you
have additional -path -helppath required, which may happen on some setups)
no, convolution is a bunch of sample-wise shifts and [*~] and [+~]
together (as many as there are values in the convolution kernel).
Yes, but conceptually convolution is converting time domain sounds into
frequency domain, storing the values in a sample block, and multiplying
the two blocks together (and normalizing of course).
Convolution can be defined in two completely equivalent ways: one as
polynomial product in the time domain (using a z-series representation)
and one as the complex multiplication of two frequency spectra using an
infinite blocksize.
Almost all of the time, the time-domain representation is taught first.
This might be especially important as the frequency-domain only becomes
tangible once some kind of Fourier transform is in place, and the
polynomial product is certainly easier to explain than the Fourier
transform. (and that's even more true for realtime)
But if you want to apply convolutions with large kernels and/or large
pieces of data, you really have to use [fft~] (for sound) or [#fft] (for
spatial-frequencies of images).
So if one block has no sound at 300Hz and the other block does, the
resulting block does NOT have sound at 300Hz, right?
Right.
So if your block size was four and you had one FFT block that was:
0,1,0,1 And another that was: 0,0,0,1 The convolved real sound block
(before going to ifft~) would be 0,0,0,1 Right?
Yes, supposing each of those values is a complex number. But that's
because AND is a special case of multiplication, because:
0*0 = 0
0*1 = 0
1*0 = 0
1*1 = 1
so * over {0,1} is exactly AND.
