Re: [PD] Data structures: no object for freeing pointers?
Yes with visibility setting we can access an element of an array only, so each state can be stored, retrieved, replaced at will by accessing an element of te array... The matter is how accessing an element, idealy it would be a [nbx] where max value is the number of array elements, or a that's very easy, just get the number of elements from the array's pointer, and send it as [max $1( to the nbox (or whichever command defines the limits, I don't have Pd open). scalar but I don't how it's possible to fix limits to [drawnumber] I think not from the gui. Unless you enforce it programatically: route the change output from the [struct] in the template, and use it to force the maximum number to a [set] object. Like: [struct drawnumber...] | [route change] | [50( (assuming 50 is the current max number) | [set drawnumber...] In a parallel part, the current pointer gets and sets the maximum number of elements (now at 50) Look at the current help file for [drawnumber] for more details.

Re: [PD] compiling pix_opencv on debian (lmde)
hi Antoine I've push a fixed version to svn it should work with both version could you please test it with 2.4.5 ? nice, it seems that all externals build fine now (except for pix_opencv_surf but it looks like it should not be build in the first place..).

Re: [PD] how to install and use GPIO external
Awesome! I got it working! Thanks for all the help! One more question, does anyone know if you can set the internal pullup/pulldown for the GPIO pins from within PD and if so how you can set this?

No error messages but where should I expect to see the high/low state of GPIO 17? it should come out of the object into a number box or toggle as far as I can remember... put a number box in the outlet of the gpio object. J Should this be reflected in the bang object in the script (white for low and black for high)? I have the poll input check box checked. When I toggle the voltage on GPIO 17 from 3.3V to GND I do not see anything change in the script. I am able to see the high/low state of the pin 17 change by using the readall command from LXTerminal so I know that I'm switching the voltage correctly on the right pin, just not seeing how I get this status in pure data using the gpio-help.pd script. Any thought on how I do this? Sorry I have very little experience with pure data and am just learning.

So I deleted the -m32 from the makefile and then everything seemed to build okay. I then added the correct path for the extension in pure data and loaded the gpio-help.pd patch without getting an error message. In the gpio-help.pd patch I would click enable 1 and then click open 1 and after clicking open 1 I would get an error message: /sys/class/gpio/gpio17/value: No such file or directory. I then realized that I probably needed to install wiringPi. I downloaded this and installed it. However I would still get the previous error message within PD. I then decided to manually try to create the file using commands in LXTerminal. I did this using this command, echo 17 |sudo tee /sys/class/gpio/export. I then noticed that the gpio17 folder and accompanying files were created. I was also able to correctly read the state of the pin using gpio readall command from LXTerminal. I then loaded the gpio-help.pd file again in PD. Now once I click open 1 instead of the no such file or directory error I get /sys/class/gpio/gpio17/value: Permision denied error. Is there someway I can use this GPIO library within the PD visual interface without getting permission denied errors? Also, shouldn't clicking enable 1 within the gpio-help.pd patch create the /sys/class/gpio/gpio17 folder and accompanying files? How can I get this to work within PD without having to run the commands from LXTerminal to create the folder/files? Do I need to somehow indicate to pure data the path of wirngPi? Almost there! Really appreciate your guys patience with me and help on this!

[PD] AUDIO from movies with pix-film?
Hello
a friend on the supercollider list is asking about playing movies in
Pure Data from SuperCollider and is mentioning that there is no sound
coming from her movies, how can one easiest get audio from a movie to
play in Gem[pix-film?
Is this possible on MAC?
I have attached the simple patch(s)
Patrick
//• SuperCollider to PureData
// Use loopback IP and the same port as the pd patch to communicate
~pdOut = NetAddr(127.0.0.1, 47110);
// test it with one message:
~pdOut.sendMsg(/from_SC, 0);
//
~pdOut.sendMsg(/from_SC, 1);
