Hello. I'm trying to use Arduino with Puredata using the Firmata Library. I downloaded Firmata and installed the library as instructed in the readme, and then loaded 'AnalogFirmata' from the library examples. When I try to compile this example (or any of the others) I receive a string of error statements. Code and errors listed below. Any suggestions?

Code:

/* This firmware supports as many analog ports as possible, all analog inputs,
* four PWM outputs, and two with servo support.

In function 'void setup()':

I've got an Arduino Diecimila which works perfectly with PD. It really is super simple to set up!

1. Download Pduino AND Firmata:
http://at.or.at/hans/pd/objects.html
2. Download Arduino Software for your operating system:
http://arduino.cc/en/Main/Software
3. Attach your Arduino board via USB cable, launch Arduino Software and open "Standard_Firmata" from Firmata/examples. Upload this to your board.
4. Launch PD and open "arduino-test.pd"
5. Select the right COM port (click on each one until PD message window reports something positive). Then enable the PIN you've got your sensor attached to. Value in a relevant box will start updating. If you haven't got a sensor but just want to make sure it's working, click "Pulse all outputs". An LED on the board will start flashing repeatedly.

That's all you need to get going.
Let us know how it goes.

Good luck!

@lunchbox said:

is there any differences between the firmata and the simple messaging system? I'm also working with IR sensors, arduino connected to PD, and i need to read inputs from the arduino, so which external is better? I've tried the firmata, it works well, but i still don't get how this external works...

Yep, there is a difference. The difference is that firmata is designed to let everything happen in software, rather then on the arduino (see my attached example on the other post for an example of how to read your IR sensors)

Better is subjective. I like Pd coding better, so I use pduino and firmata.

So, to recap, burn firmata standard on your arduino, use Pduino, and code the app in pd, for easy, graphical, dynamic programming (pd-style) otherwise, interpret the messages in some other format, and do it some other way. It's up to you.

My attached example is definitely the easiest way to achieve your goals, in my opinion. You get the bonus of having pretty simple conversion from Arduino-languuage examples into pd-friendly code, rather then using some intermediary language that you have to code for on both ends (arduino interprets inputs, emits OSC or something else on serial, pd interprets OSC or something else and does stuff, blech!) instead you can just route incoming messages in pd, the same way you would with midi, a joystick, keys, or whatever.

Once you get pduino all setup, and my above patch works, try right-clicking on Pduino object, and choosing help. It actually has a pretty nice help file, which is how I figured all this out.

*Warning* The baud rate 1089216512 is not suported or out of range, using 9600

The baud rate that is in your arduino code must be the same as the baud rate in your arduino PD patch.
One hint: the baud rate in the arduino-test patch is 57600, this must be the same in the code of your arduino board, otherwise it won*t work porperly. You can see that opening [arduino 1].

Hey,

thanks to everyone who responded to my posts both here and in the mailing list. Since then, I've figured out how to compile externals written in C using Microsoft Visual C++ 2005. There's more to document, however, such as how to compile externals using some of the other Windows compilers (Borland, djgpp, etc.), and also how to compile externals written in C++ in Windows. But one thing at a time.

one little thing to note... steps 4 and 7 may seem a little roundabout, but they account for the fact that MSVC sometimes has trouble with spaces in directory names (eg. C://Program Files/). If anyone knows how to override this behavior, post a reply, and I'll try to simplify the steps accordingly.

Updated June 29, 2007:
use [b]C://Progra~1/[/b] instead of [b]C://Program Files/[/b],
use [b]C://Docume~1/[/b] instead of [b]C://Documents and Settings/[/b], etc.

So, without further ado...

How to compile a pd external written in C using Microsoft Visual C++ 2005:

Compared to Windows, linux offers a much more user-friendly environment for compiling pd externals. However, with a little patience, a usable environment can be set up in Windows, and the good news is that everything you need is available for free. There are several reputable Windows-compatible C/C++ compilers out there, but here I'll discuss compiling externals with Microsoft Visual C++ 2005 (MSVC for short).

1. Download and Install Microsoft Visual C++ 2005 Express Edition.
a. Click the link above, then click Go! in the Visual C++ box.
b. Run vcsetup.exe to install the program
(the setup wizard should guide you through the process).

2. Download [url=http://download.microsoft.com/download/7/7/3/7737290f-98e8-45bf-9075-85cc6ae34bf1/VS80sp1-KB9267
]Visual C++ 2005 Express Service Pack 1.
a. Click the link above to download the Service Pack.
b. Run VS80sp1-KB926748-X86-INTL.exe to install the program.

3. Create a new project:
a. Open Visual C++.
b. Open the New Project window (Ctrl+Shift+N).
c. In the Project Types pane, select Visual C++.
d. In the Templates pane, select emptyproj.
e. Enter object name (helloworld).
f. Leave Create directory for solution unchecked, and click OK.

4. Import the pd header file:
a. Get m_pd.h here, or, using pd-vanilla (not pd-extended):
1. Open Windows Explorer or My Computer.
2. Navigate to the pd/src/ directory on your system.
3. Open m_pd.h in a text editor (file type is: C/C++ header).
b. Select all (Ctrl+A).
c. Copy selection to the clipboard (Ctrl+C).
d. Back in Visual C++, open the New File window (Ctrl+N).
e. In the Categories pane, select General.
f. In the Templates pane, select Text File, and click Open.
g. Copy the contents of m_pd.h into the editor window (Ctrl+V).
h. Open the Save File As Window (Ctrl+S).
i. Save as m_pd.h.
j. From the File Menu, select Move m_pd.h into; select helloworld.

5. Write the source code for the external in C.
a. Open the New File window (Ctrl+N).
b. In the Categories pane, select General.
c. In the Templates pane, select Text File, and click Open.
d. Write your source code in the editor window.

The following example is taken from the tutorial by Johannes M. Zmoelnig.

#include "m_pd.h"

static t_class *helloworld_class;

typedef struct _helloworld {
  t_object  x_obj;
} t_helloworld;

void helloworld_bang(t_helloworld *x)
{
  post("Hello world !!");
}

void *helloworld_new(void)
{
  t_helloworld *x = (t_helloworld *)pd_new(helloworld_class);

  return (void *)x;
}

void helloworld_setup(void) {
  helloworld_class = class_new(gensym("helloworld"),
        (t_newmethod)helloworld_new,
        0, sizeof(t_helloworld),
        CLASS_DEFAULT, 0);
  class_addbang(helloworld_class, helloworld_bang);
}

6. Save and import the source code into the project:
a. Open the Save File As Window (Ctrl+S).
b. Save as helloworld.c.
c. From the File Menu, select Move helloworld.c into; select helloworld.

7. Access the pd library file:

d. Navigate to the C://TEMP/ directory on your system.
e. Paste the copy of pd.lib in the C://TEMP/ directory (right-click or Ctrl-V).

8. Set configuration properties:
a. Set configuration type to .dll:
1. Back in Visual C++, open the helloworld Property Pages window (Alt+F7).
2. In the left pane, select Configuration Properties >> General.
3. In the right pane, under Project Defaults, click on
Configuration Type, and select Dynamic Library (.dll)
(using the arrow on the right).

b. Add MSW to preprocessor definitions:
1. In the left pane, select
Configuration Properties >> C/C++ >> Preprocessor.
2. In the right pane, type MSW in the Preprocessor Definitions field.

e. Tell linker to export the setup function:
1. In the left pane, select
Configuration Properties >> Linker >> Command Line.
2. In the right pane, type
/export:helloworld_setup in the Additional options field.
3. Click OK.

9. Compile and link:
a. Use the Build Solution command (F7).

10. Copy the new helloworld.dll file into pd.
a. Open Windows Explorer or My Computer.
b. Navigate to the
My Documents/Visual Studio 2005/Projects/helloworld/Debug/
directory on your system.
c. Right-click on helloworld.dll (file type is: Application Extension)
and select Copy.
d. Navigate to the pd/extra directory on your system.
e. Paste the copy of helloworld.dll in the pd/extra directory
(right-click or Ctrl-V).

11. Test the external in pd.
a. the external should now be a useable object in pd.
b. open a new pd patch and try to create a helloworld object.
c. add a bang to the left inlet and test it out.
d. if the main pd console window displays "Hello world !!",
the external has succeeded.

Hope this helps!

Hello,

please excuse my stupidity both in programming and generally in understanding PD. i've been trying to figure a way to convert a frame number (received with OSC) to a timecode but the code i tried to adapt from a matlab script by Malcolm A. MacIver that i found here http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=1116&objectType=File
involves some for...loop and i dont know how to do the same in PD... can anyone explain, please?
i guess the field part of the smpte timcode (and other bits of information) are usually not needed, for most people HH:MM:SS:FF Information will be ok... maybe with an adjustable framerate between 30 (ntsc) and 25 (pal)

greetings,
till

function smpte = dec2smpte(init, framecount, field)
% convert the smpte time from the total elapsed frames and field as an integer
% to the new smpte time

first_field=init(9);
weight=[1080000 108000 18000 1800 300 30 10 1];

ns=[];
remain=framecount;
for i=1:8
  ns(i)=floor(remain/weight(i));
  remain=remain- (ns(i)*weight(i));
end

if strcmp(first_field,':')
   second_field='.';
else                                     
   second_field=':';
end

if field==1
   field_flag=first_field;
else
   field_flag=second_field;
end

smpte=[ ...
    num2str(ns(1)) num2str(ns(2)) ':' ...
    num2str(ns(3)) num2str(ns(4)) ':' ...
    num2str(ns(5)) num2str(ns(6)) field_flag ...
    num2str(ns(7)) num2str(ns(8))];

different approach here

function itc (int "framecount", float "rate", bool "ms")
{
rate=default(rate,25)
ms = default(ms, false)

drop = (rate==29.97)? true : false
rate2 = (drop==true)? 30 : rate

hours=floor((framecount/rate)/3600)%60
mins=floor((framecount/rate)/60.0)%60
secs=floor(framecount/rate)%60
milli=floor(1000*framecount/rate)%6000%1000
fmilli=framecount/rate - floor(framecount/rate)
#frames=floor(fmilli*rate2)
frames=framecount%int(rate)

dframes = (drop==false)? frames : (secs==0)&&(mins%10!=0)? floor(fmilli*rate2) + 2 : frames

return (ms==false)? (string(hours,"%02.0f")+":"+string(mins,"%02.0f")+":"+string(secs,"%02.0f")+":"+string(frames,"%02.0f")) :
\ (string(hours,"%02.0f")+":"+string(mins,"%02.0f")+":"+string(secs,"%02.0f")+":"+string(milli,"%03.0f"))
}

there seems to be something called [table16] that can read large soundfiles, but it still seems to be the in development stage.

for the moment, the only thing i can suggest is to cut your 20 minute file into 20 x 60 second segments,

and then use something like this:

#N canvas 0 22 751 443 10;
#X obj 114 16 table 0-Right;
#X obj 15 16 table 0-Left;

#X obj 15 36 table 1-Left;
#X obj 114 56 table 2-Right;
#X obj 15 56 table 2-Left;
#X obj 114 76 table 3-Right;
#X obj 15 76 table 3-Left;
#X obj 114 96 table 4-Right;
#X obj 15 96 table 4-Left;
#X obj 114 116 table 5-Right;
