Dear Pd'ers… I'm fairly new to Pd and have been using it during my 'Audio Production' degree at SAE college in London. I'm here to ask for help on my final degree project, which aims to control objects within Pd by way of proximity sensors connected to Arduino.

I have had moderate success, first using a Sharp GPD12 IR sensor connected to an analog port on an Arduino Diecimila, then a Devantech SRF02 connected via I2C to Arduino. I have managed to get Pure Data reading the sensor values using the Pure Data example included in SimpleMessageSystem (http://www.arduino.cc/playground/uploads/Code/SimpleMessageSystem.zip)... and only altering the number of the comport the Arduino appears on.

On the Arduino end, I have added the SimpleMessageSystem library, and am using the following sketch to run one or both of the sensors depending on whether or not I omit the SRF02 or GPD12 parts of the code.

// top //

#include <Wire.h>
#include <Servo.h>
#include <SimpleMessageSystem.h>

int sensorPin = 0;
int sensorValue = 0;

Servo servo1;

#define sensorAddress 0x70
#define readInches 0x50
#define readCentimeters 0x51
#define readMicroseconds 0x52
#define resultRegister 0x02

void setup()
{
Wire.begin();
Serial.begin(9600);
}

void sendCommand (int address, int command) {
Wire.beginTransmission(address);
Wire.send(0x00);
Wire.send(command);
Wire.endTransmission();
}

void setRegister(int address, int thisRegister) {
Wire.beginTransmission(address);
Wire.send(thisRegister);
Wire.endTransmission();
}
int readData(int address, int numBytes) {

int result = 0;

Wire.requestFrom(address, numBytes);
while (Wire.available() < 2 );{
}

result = Wire.receive() * 256;
result = result + Wire.receive();
return result;
}

void loop()
{
// SRF02 READING //
sendCommand(sensorAddress, readInches);
delay(70);
setRegister(sensorAddress, resultRegister);
int sensorReading = readData(sensorAddress, 2);
Serial.println(sensorReading);

delay (200);

// GPD12 READING //
sensorValue = analogRead(sensorPin);
int range = (6787 / sensorValue);
Serial.println(range);

delay(200);
}

// bottom //

Pure data is picking up the sensor's output as a decimal number, through the serial port, correctly, and showing this as a number in the SPECIAL CHARACTER section of the Pd patch, which I can then use to control various Pd parameters, like a slider for example.

If printing both sensor readings to the serial, the Pd patch will pick up the two sensor values alternately, but there seems no way of differentiating the two sensors within Pd, as they both come through the serial. I have tried prepending the serial print at the Arduino stage with a tag such as "IR" or "UL" for each sensor, but this simply ends up in nothing coming through in Pd.

Using one sensor gives the ability to control parameters with a fairly narrow detection range, but for the final version I would like to incorporate 4 or 5 sensors in order that I can cover nearly a full 360 degree range.

After a bit of research I have gone and bought 4 x Maxsonar EZ0's. They've got a wider range than the Devantech sensors, and can operate via I2C, serial or PWM. A number of people online seem to mention the improved stability when operating via PWM, so I thought this could be kinda useful.

I am going to London Hackspace tomorrow to get help with wiring up the sensors to my Arduino Diecimila, but for now, my main problem seems to be how to achieve greater communication between Pure Data and the sensors. It's all very good and well being able to take the decimal readout from an analog input to give one set of values in Pd, but I would like to know how to either to read (and trigger) each sensor discretely via PWM, or to somehow differentiate between each sensor's analog output, so that I can have the different sensors controlling different objects within Pd.

As well as SimpleMessageSystem, I looked at using the Pduino object. But to be honest, it is either not working properly (I have noticed reported issues with bugginess), or I am being stupid, as it has totally boggled my brain. In theory though, it seems like it should be able to do what I want, ie. send and receive commands between Arduino and Pd.

****************************************
So&#8230;. my questions for anyone out there with a knowledge of using Arduino + multiple sensors (preferably Maxsonar EZ's) with Pd are:

What is most appropriate for my project?

• Simple Message System or Pduino?
• analog or PWM?
  And how do I get proper communication between the two platforms so I can discern discrete values from each sensor?

I'd really like to get a discussion going with this as (a) it would really help me in my degree (which ends in about 4 weeks!!!) and (b) I really want to share what I am doing, especially as the discussions on Arduino/Pd communication on the various forums seem a little patchy (at least for noobs like me). I also hope to continue my research in the future, sharing any findings I make with the community&#8230;
****************************************

PS. In the sharing spirit, please check out the Radio Tuner patch I've just posted over on the patch section of this forum - it's my first successful attempt at Pd... I hope you enjoy

Hello,

Really new on pd.
Firstly I want to do the audio settings with my soundcard MOTU 828 mk3 and test them with the patch testtone.pd (launched by Media/Test Audio and MIDI).

In Media menu, I have the choice between "standard (MMIO)" and "ASIO (via portaudio)".
1/ Choosing "standard (MMIO)", I could theoretically set up to 4 output devices ("MOTU Analog 1-2" --> "MOTU Analog 7-8"), 2 channels for each one. But when I do this I have no sound, and have the message : "separate audio device choice not supported\; using sequential devices."
In fact it seems I'm allowed to set only one output device. When I do that, it works, I have sound for channels 1 and 2 (1 and 2 in pd, but it can be physically 5-6 for example, depending what I choose in the settings).

But I have only 2 channels...

2/ Choosing "ASIO (via portaudio)", exactly the same situation, except that the output names are now "(0) MOTU Analog 1-2", "(0) MOTU Analog 3-4"...
Note that I also have a new output, "(1) MOTU Audio ASIO" which doesn't work (I tried to set 2 channels or 8, same result)

Could someone light me on the multichannel configuration in pd ?
Maybe I have to configure something in the MOTU (via CueMix FX), but I don't know how...

Thank you in advance for your help or advices.

Matthieu

Greetings all,

I have just posted a collection of student patches for an interaction design course I was teaching at Emily Carr University of Art and Design. I hope that the patches will be useful to people playing around with Pure Data in a learning environment, installation artwork and other uses.

The link is: http://bit.ly/8OtDAq
or: http://www.sfu.ca/~leonardp/VideoGameAudio/main.htm#patches

The patches include multi-area motion detection, colour tracking, live audio looping, live video looping, collision detection, real-time video effects, real-time audio effects, 3D object manipulation and more...

Cheers,
Leonard

Pure Data Interaction Design Patches

These are projects from the Emily Carr University of Art and Design DIVA 202 Interaction Design course for Spring 2010 term. All projects use Pure Data Extended and run on Mac OS X. They could likely be modified with small changes to run on other platforms as well. The focus was on education so the patches are sometimes "works in progress" technically but should be quite useful for others learning about PD and interaction design.

NOTE: This page may move, please link from: http://www.VideoGameAudio.com for correct location.

December 5, 2009

12:00 -- 1:30 PM : Introductory workshop on Pd with Hans-Christoph Steiner
2:00 -- 6:00 PM : SkillShare w/Steiner and members of RjDj programming team

Free, capacity for up to 30 participants

RSVP HERE: http://tinyurl.com/ykaq3l3

Hans-Christoph Steiner returns to Eyebeam with members of the RjDj programming team from Europe to help turn your iPhone or iPod-Touch into a programmable, generative, and interactive sound-processor! Create a variable echo, whose timing varies according to the phone's tilt-sensor or an audio synthesizer that responds to your gestures, accelerations and touches. Abuse the extensive sound capabilities of the Pure Data programming language to blend generative music, audio analysis, and synthy goodness. If you're familiar with the awesome RjDj, then you already know the possibilities of Pure Data on the iPhone or iPod Touch (2nd and 3rd generation Touch only).

Creating and uploading your own sound-processing and sound-generating patches can be as easy as copying a text file to your device! In this 4-hour hands-on SkillShare, interactive sound whiz and Pure Data developer Hans-Christoph Steiner and several of the original RjDj programers will lead you through all the steps necessary to turn your phone into a pocket synth.

How Eyebeam SkillShares work

Eyebeam's SkillShares are Peer-to-Peer working/learning sessions that provide an informal context to develop new skills alongside leading developers and artists. They are for all levels and start with an introduction and overview of the topic, after which participants with similar projects or skill levels break off into small groups to work on their project while getting feedback and additional instruction and ideas from their group. It's a great way to level-up your skills and meet like-minded people. This SkillShare is especially well-suited for electronic musicians and other people who have experience programming sound. Some knowledge of sound analysis and synthesis techniques will go a long way.

We'll also take a lunch break in the afternoon including a special informal meeting about how to jailbreak your iPhone!

Your Skill Level

All levels of skill are OK as long as you have done something with Pd or Max/MSP before. If you consider yourself a beginner It would help a lot to run through the Pd audio tutorials before attending.

NOTE: On the day of the SkillShare we will hold an introductory workshop from 12:00 until 1:30 PM, led by Steiner, for those who want to make sure they're up-to-speed before the actual SkillShare starts at 2:00. The introductory workshop is for people who have some done something in Pd or Max/MSP but are still relative beginners in the area of electronic sound programming.

What You Should Bring

You'll need to bring your iPhone or iPod Touch (2nd or 3rd generation Touch only), your own laptop, a headset with a built-in mic (especially if using an iPod Touch) and the data cable you use to connect your device to your laptop. Owing to a terrific hack, you won't even need an Apple Developer License for your device!

More Information

RjDj is an augmented reality app that uses the power of the new generation personal music players like iPhone and iPod Touch to create mind blowing hearing sensations. The RjDj app makes a number of downloadable scenes from different artists available as well as the opportunity to make your own and share them with other users. RjDj.me

Pd (aka Pure Data) is a real-time graphical programming environment for audio, video, and graphical processing. Pd is free software, and works on multiple platforms, and therefore is quite portable; versions exist for Win32, IRIX, GNU/Linux, BSD, and MacOS X running on anything from a PocketPC to an old Mac to a brand new PC. Recent developments include a system of abstractions for building performance environments, and a library of objects for physical modeling for sound synthesis.

@Maelstorm said:

If you're on OSX, jack can be used as an insert plug-in so you can avoid the separate tracks, but you still get the latency.

which you can, depending on your host, eliminate by setting the track delay for the track with the plugin. So if the buffer is 512 sample/11.82 ms then set the delay to that and it should be spot on.

I've had the whole Jack graph latency explained to me numerous times by Stephane Letz and it still doesn't go in.....Heres what he told me...

didnt know jack also worked for windows xp?

EDIT:just downloaded jack from the website,but i get all kinds of errors when i try to unzip?

i'd really love to check out, what you have build there!

I hope I did this right: I opened Console, then launched PD. I've pasted the contents of the console window below (after that I pasted the contents of pd.crash.log

Hello!

I just came from a 4 day workshop about PD. I liked it so much that I already bought arduino, a couple of sensors and a webcam.
Anyway I was working on college computers and everything was ready to use, but now I installed it on my pc and I can't read wave files from it.

The error is:
"signal outlet connect to nonsignal inlet", and it happens every time I try to play a .wav file, when I select "compute audio" on console, when I select "Audio on", and every time I touch on "audio settings" or "ASIO".
I run the "test audio and MIDI" and I can hear both test signals. I've tried using some example patches in the 3.audio.examples folder and I could hear pc sounds.
Happens either I use GEM or not.

I made a file that has a .wav and I'm using the webcam as motion sensor to change the sound pitch. As I try to play the .wav, the console shows that error.
The .wav file is in the same folder as the PD file ofc.

I searched the forum and google for solutions:
@Thor said:

Go to Preferences > Audio Settings
then choose your built-in-audio or whatever device you use
I have noticed that when I use my isight with GEM, PD sometimes defaults to use it as input AND output (!)
try that and I bet you will be ok

=didnt work

@nickj said:

If you have a camera plugged in (ichat) , go into preferences -> audio settings then untick the input (isight) device 1.

=didnt work - dont have ichat cam but still I checked if it had any sound input and it doesnt.

@http://en.flossmanuals.net/PureData/TroubleShooting said:

I get the message "error: signal outlet connect to nonsignal inlet (ignored)" when I open a patch.

This error tends to go with the previous error "I get the message '... couldn't create' when I open a patch...". Often this error means that an object has failed to create, usually because it uses an External Object which is not available in the current installation or configuration of PD. PD will preserve the location and connections of an object which fails to create, but it will not function. You can use the "Find last error" function under the "Find" menu to track down which objects caused errors. PD will treat uncreated objects as Dataflow Objects even if they were originally Audio Objects, so this error will follow the previous one. Please see the relevant sections in the "Configuring PD" chapter for information about setting the "Path" and "Startup" options. If the External is not available in PD Extended, you may need to install it yourself.

now I ran out of ideas and just decided to ask...

I have:

• Pd-0.40.3-extended
• Win XP SP2
• Vimicro USB pc cam (VC0305)
• Realtek AC'97 Audio

If anyone can help, thx in advance.
