[Discuss-gnuradio] GRC: setting parameter for multiple blocks via combo box

[Rob Heig]

Hi everybody,

I am creating a small design (similar to the DVB-T one included in
gnuradio-dtv) and I wanted to set some parameters once (at design and *not*
at execution time) with a combo box (to limit the possible choices to valid
values only). For instance, if we consider the above mentioned DVB-T
design, one might want to set the chosen constellation just once and not
for every single block that needs that parameter. Is there an easy way to
achieve this result?
Thanks a lot in advance and have a nice day!

I'm not sure if this fits your requirements, but you can use a stand 
alone Python script. Here's an example for the DVB-T transmitter.

Thanks for your answer Ron!
Unfortunately no, we plan to play with blocks in the GUI and so no Python
script or C++ code, at least at the beginning... :(

[Discuss-gnuradio] [GSoC'18][MIMO] Updates of the week

[Luca Schmid]

Hi all,

I just finished the implementation of the V-BLAST architecture as another
algorithm for the collection of basic MIMO capabilities for GNU Radio. For
general MxM schemes with M>2, I am using the linear algebra library Eigen3.

Here is my blog post

for this week.

Best

Hi,
And using a QT GUI Chooser with type "Any" and using its entry to configure
the other blocks?

Re: [Discuss-gnuradio] GRC: setting parameter for multiple blocks via combo box

[Rob Heig]

Mmmm, no :(
In this way, I cannot select the value from a combo box (unless at runtime,
but I would like to do this at "design" time, as it is done by normal combo
boxes to select enum values in the .grc files).
Thanks anyway!

Re: [Discuss-gnuradio] ImportError: No module named 'gnuradio'

[Kyeong Su Shin]

Hello Evans:


(Also, if you haven't installed the Windows distribution of GNU Radio, get it 
from here: http://www.gcndevelopment.com/gnuradio/downloads.htm . Then you can 
use the GNU Radio command prompt to execute your Python code.)

Kyeong Su Shin

Hello Evans:


As the error message says, your Python binary is not seeing the Python module 
named 'gnuradio'. It simply does not have right libraries to run your Python 
code.


If you installed the Windows distribution of GNU Radio, one thing that you must 
note is the fact that the distribution uses its own Python binary and 
libraries. It will not touch other Python installations on your PC, and use its 
own copy of CPython for the operation. The easiest workaround in such 
situations would be running your Python code on the GNU Radio Command Prompt, 
not on the default Windows command prompt. In that way, you can use the Python 
binary installed and used by your GNU Radio distribution to execute your code.

Hi Evans,

Just for clarification: 

You did install GNU Radio on your windows, right?

[Derek Kozel]

Hi Evans,

I believe the current GNU Radio installer on Windows includes its own full
local copy of Python. You will have to use that version of Python whenever
you are using GNU Radio. I don't have a Windows machine running at the
moment to check, but I believe that there are scripts included with the
installation for launching that Python environment.

Derek

[Discuss-gnuradio] Need help with CtrlPort Performance Monitor

[Jim Larsen]

I want to use the CtrlPort Performance Monitor block to compare CPU usage of 
several demodulator alternatives. I built GNU Radio version 3.7.12 using 
PyBOMBS on Ubuntu 18.04. I added -DENABLE_PERFORMANCE_COUNTERS=ON to the 
gnuradio.lwr recipe. I installed  networkx, matplotlib, and python-pygraphviz. 
I edited gnuradio-runtime.conf as follows:

[ControlPort] on = True
[ControlPort] edges_list = True
[PerfCounters] on = True
[PerfCounters] export = True

I ran a simple flowgraph Signal Source > Throttle > Null Sink with the CtrlPort 
Performance Monitor block. The Performance Monitor window opens, but the graph 
is empty. Please let me know how to make CtrlPort Performance Monitor work.

Thanks!
