Re: [Discuss-gnuradio] [Announcement] GNU Radio pre-3.8: pre-Change notification

[Marcus Müller]

Cheers Martin,

honest point is that I haven't tested that, and I also don't know
whether our install scripts install our own CMake files in the right
directory when you mix apt-get/dpkg and pip. (Nota bene: I'm not a
great fan of installing system software through third party tools
globally, but you know that ;) ). From a usability point of view,
finding an official PPA from the CMake folks that contains a backport
that properly conflicts with the CMake Ubuntu ships would be
desirable. 

Fight the competing-installation problems!

Let's make this work,
Marcus

Re: [Discuss-gnuradio] Custom gnuradio GUI for OOT blocks

[CEL]

Hi Laura,

first: Don't use WX. It's dead, and we've deleted the code from the
coming releases. Use Qt, we support it well.

Why do you need to *recompile* C++ code through the GUI? That sounds
architecturally more than questionable. It also contradicts what you
say: you just want to call C++ functions from your GUI. But maybe I'm
missing something here; if so, please elaborate!

The latter is actually not that hard – assuming your functions are
callable from Python (and our build system takes care of that!), you
can just use them as Qt "SLOT"s, which means that you can connect an
event (e.g. a button click) to them in Python. 

So, you'd need no extra framework at all – GNU Radio and our python
wrappers and Qt do all this for you :)

Best regards,
Marcus

Re: [Discuss-gnuradio] GSoC Participation

[CEL]

Hi Rachuri,

thanks for reaching out!
So, you're planning on applying for with own project idea – which is
great; it shows enthusiasm and a high confidence you know what you're
signing up for. Problem is: while for all the ideas on the ideas list
mentors are already assigned, someone from the GNU Radio developer
community would need to be willing to mentor your specific project. At
this point, we don't have someone like that, but I'd assume most of us
haven't even read your mail yet. Still, this increases your risk of not
being accepted if we simply don't find a mentor.

So, because we need to find someone who'd be willing to mentor you,
you'd need to come up with a pretty detailed design plan, so that we
get the picture of what you want to implement. This would especially
mean you'd have to address the foreseeable problems in your proposal.

From the top of my head, these would be dominated by timing
uncertainty, and how to modularly implement things so that e.g. the MAC
mechanism or the flow control can be exchanged. Timing uncertainty is
what usually comes hardest for SDR MACs – you'd need to address how
you'd solve the problem that the delay (between receiving some data to
having detected / calculated a time at which you'd want to send ) might
be pretty random, and also pretty large.

All in all, this is a very open-ended problem, and to me, it sounds
very much like a systems architecture problem that needs to come up
with a clean and useful API that has both some educational value as
well as actually working over the air. A large project, even for
experienced developers!

Best regards,
Marcus

[Discuss-gnuradio] Symbol to chip Mapping

[Achilleas Anastasopoulos]

Yes this can be done with chunks-to-symbols.
This is essentially a 16 x 32 lookup table:

turn your 4 bits into a byte which indices a lookup table with 32 dimensions
(set the "dimension" variable to 32 in chunks-to-symbols).

[Discuss-gnuradio] need example Costas loop code

[Chesir, Aaron M.]

Folks,

I am going through a series of on-boarding projects using GNUradio, and one of 
the projects requires access to a copy of Python source code for an example of 
a Costas loop. Specifically, the project refers to a file 
"gr-digital/examples/examples_costas.py",
 which was developed for the GNUradio project by Rondeau Research. 
Unfortunately the link in the web page (http://www.trondeau.com/gr-tutorial/) 
that should have pointed to the location of the source code is a broken link.

If any of you have come across the referenced source code, could you please 
email me a copy?

Thanks in advance,

Aaron

Re: [Discuss-gnuradio] Custom gnuradio GUI for OOT blocks

[Laura Arjona]

Thank you very much Marcus, I do appreciate your help,  I only have
experience with GUIs in android .

The big picture is to change the behavior of the OOT blocks based on the
user input; and the user interacts with the system using widgets (buttons,
edit texts, etc)

You were right, I don't need to recompile the C++ code, I didn't think it
properly.

To give you an example of what I want to do, let's say I have a transmit
block named *myBlock* (oot block, c++), which has a function *f*, and that
function, has a parameter int n.
Then, I have a main.py file, which launches the application (consisting of
several connected blocks), with a declaration of that block

*self.myBlock   =  myModule.myBlock()*

I want to launch the main.py using a GUI by pressing a *button*, and
selecting the parameters of the function f. These parameters should be
selected with widgets (buttons or some other)

Also, which widgets are possible to use? (buttons, editText, etc)


I looked at the documentation, but it is only about blocks for plotting

Re: [Discuss-gnuradio] Installation of gr-radar

[CEL]

Why? That's an embedded platform, slower than your PC; you wouldn't
want to do any software development on that.
Also, it's not the right platform to do radar on, unless you've
verified your system on a faster platform and are planning to only do
pretty narrowband stuff.

Re: [Discuss-gnuradio] Installation of gr-radar

[CEL]

I'll humbly recommend you directly do this on your PC. Adding an
embedded platform to this mix will only complicate things, and at this
point, you're clearly at no level of competence to solve these
complications yourself.
We generally go the other way around: do something on a PC, prove it
works there, then port to your Raspberry Pi.

Best regards,
Marcus

Good catch.

Talha will be able to build it on a ARM but probably won't be able to
run it.

Re: [Discuss-gnuradio] Symbol to chip Mapping

[Tellrell White]

Okay. Let me make sure i’m clear on this.

My flow graph looks like the following : 

Random source -> packed to unpacked -> chunks to symbols 

The source and packed to unpacked are set to byte and the packed to unpacked is 
outputting 4 bits per chunks so am I setting the dimension of the “chunks to 
symbols” block to 16 (0-15) and inputting 1024 values, 0’s and 1’s, (32 values 
for each dimension) to complete the mapping?

Thanks for the assistance.
