Re: tcpserver crashes on the 34th client connection

Martin Peach — 2013-05-19T01:17:54

Yes, it seems that the routine that adds new connections doesn't check 
to see if it has passed the number of connection slots.
There are MAX_CONNECT slots allocated when [tcpserver] starts.

Thanks for finding this bug!

There is no reason to limit the number of connections to 32 except to 
not use up memory.
I think it could be changed to either dynamically add space for new 
connections without limit or set MAX_CONNECT with a creation argument.

For now you could recompile it with MAX_CONNECT set to another value. 
(At some point the OS will run out of sockets. Before that Pd will slow 
down...)

#define MAX_CONNECT 10000

Re: tcpserver crashes on the 34th client connection

Antoine Villeret — 2013-05-18T21:37:38

so I reply to myself...

I found this in the code of both tcpserver.c :
#define MAX_CONNECT 32 /* maximum number of connections */

which could be an answer embryo

so, I shouldn't make more than 32 connections on the same tcpserver, ok,
but why ?
is there a good reason to fix this to 32 ?

and this doesn't tell me why it crashes...
reaching the MAX_CONNECT should handles in the code isn't it ?

cheers

Re: RPI + new canvas position

Matthew Walsh — 2013-05-18T19:02:21

Since Raspbian uses LXDE (which uses the OpenBox WM), I used the
new-window-positioning fix mentioned here:

http://comments.gmane.org/gmane.comp.multimedia.puredata.general/86348

The fix, to pdtk_canvas.tcl, involves changing:

set x [ expr $x % $screenwidth - $::windowframex]
set y [ expr $y % $screenheight - $::windowframey]

to:

set x [ expr max($x % $screenwidth - $::windowframex, 0)]
set y [ expr max($y % $screenheight - $::windowframey, 0)]

On my Pi, it works for both Vanilla and Extended.

Cheers!

Are there multiple libgsl libraries linked?
Who is the other user of libgsl?
If this is a problem I could probably upgrade the GSL to a new version, 
or disable it since I'm not sure if it is used in anything else but the 
experimental defunct matrix stuff.

and was just reminded of it when i saw claude's bitbreader program he
mentioned a couple of days ago. for those interested:

i had intention of doing something similar to bitbreader but never got
around to figuring it out.

Re: how to know if a file has more than one channel?

You could first read the file into [iemlib/soundfile_info] and take the 
fifth item in the output list, which is the number of channels.

altern — 2013-05-18T13:57:53

hi

I would like to be able to distinguish between mono and stereo files at
loading time. I am loading the sound with soundfiler using this messages
which works both for stereo and mono files

read -resize path_to_file table1 table2

any suggestions? maybe there is some way to check if the second table is
full with zeros?

thanks

Antoine Villeret — 2013-05-18T12:24:03

Hi Patrick,

If you want to play video file with hardware decoding, speed control and
perspective correction (useful with video projector) you should have a look
at my rpi_osc_video_player :
https://github.com/avilleret/rpi_osc_video_player

There is an example pd patch to control it

This is a work in progress, mostly a proof of concept, there is no support
for sound playback for now, but it could be added when I have
time/opportunity

Feel free to try it

Cheers

Antoine

In raspian there's some way to select whether audio goes out the line out
jack or the HDMI port - I can't remember but that should be findable.

Re: OT: raspberry pi

Pagano, Patrick — 2013-05-17T22:54:19

Hi everyone and thank you for the help and links. I got wheezy up and running and installed pd-extended. I could not get audio out of the headphone jack on the Pi, but it comes out of the monitor that has HDMI on it. I then of course got greedy and over-clocked it and corrupted the file system. grrr. I picked up a mini usb audio card a Soundblaster X-fi GO! Pro and in the boot screen it sees it and it's in the drop down menu for AUDIO SETTINGS but i cannot do anything after i select it and the whole system freezes. I am wondering if jack may help with it.
I got pdp working with pdp_sdl as the window outputs, pdp_glx and pdp_xv do not work.
I am going to try to get Gedit and Supercollider working before i punt it into the Rubbish Bin. I may just use it to control DMX lighting with a USBDMXPro but as of now I am need some inspiration for it's use. :-)

cheers~ and thanks

Re: Sensors GPIO Raspberry Pi Pd

Julian Brooks — 2013-05-17T15:42:52

Aargh - you're right, I am confused (so very)...

So, to be clear
#define SENSOR_SELECT_PIN 11
should be
#define SENSOR_SELECT_PIN 17
After all?

It is then going to pin 11 on the 4051.

Running as root so need for sudo (yes I know)

As Max Romeo said:
"One step forwards, two steps backwards" :)

Will try the led test and the updated code when I can get back to it in a
couple of days or so.

Re: Sensors GPIO Raspberry Pi Pd

Martin Peach — 2013-05-17T15:20:58

It looks like you're confused about the GPIO pin.
SENSOR_SELECT_PIN should be 17 because that's what the ARM chip calls 
it. The fact that it is on pin 11 of the header is irrelevant to the 
program.
The next confusing thing is that GPIO17 on pin 11 of the header connects 
to pin 11 of the 4051.
If you want to see if the pin is working you can put an LED from pin 11 
of the header to ground and see if it flashes when you run the program.
I had to run it as sudo because regular users don't have permission to 
access the GPIO pins.

Hey Patrick,

I guess the standard most up to date raspbian wheezy is the best place to
start.

For me what's worked best is to find a super-minimal install and then build
requirements on top of that.

With the project I'm working on atm I couldn't get my pmpd patch to even
run with the standard install (there is quite a lot going on though).  Now
the patch runs fine with a whole heap of other stuff on top of that (2
sensors, 6 channel soundcard etc).  My htop reading fills me with joy-I
think there's about a dozen processes including 3 shells.

As it's a rev1 board I built a system on top of the hexxeh image (same guy
who's done the 'rpi-update' program for updating the firmware.  My
understanding though is that with rev2 boards don't do it.

The one that I've been keeping my eye on, and they've just released a brand
new version is Mobius
http://moebiuslinux.sourceforge.net/
This is what I'll be testing out for my rev2 boards.

There's a whole host of conflicting info re RPi's out there, particularly
overcl

Re: Sensors GPIO Raspberry Pi Pd

Julian Brooks — 2013-05-17T14:50:29

Sorry meant to attach the code (doh!).

My compadre has all the photo's on his phone so will give him a nudge now
and get back to you when I hear from him...

(hey George:)

Thanks for the testing tip - of course, seems so obvious now that you've
said it.

And I guess we can't definitely confirm that the pin switches although the
last big problem we had was that I'd set the switch to pin 17 rather than
pin 11 (gpio 17).  What would happen then is that we would get one reading
from the 1st sensor and then it would stall/quit-out.

More soon hopefully,

Julian

Sure.


You need to show me your code... The file I sent was to read two 
sensors. The second was the 1X8 sensor so it reads a different number of 
bytes. You have to change that, everything else should be the same..



Yes, just connect the A select line of the 4051 (pin 11) directly to 
3.3V or ground to select one or the other. But disconnect the GPIO pin 
when you do that.


Sounds like the multiplexer isn't working right. Do you have a photo of 
your setup? Can you confirm that the GPIO pin switches?

Martin
