Re: Regarding GNU radio file Sink

[Wolfgang Wilde]

You can't. It is pure raw data from the A/D converters without Meta-data 
and without any structure

Re: Regarding GNU radio file Sink

[Johannes Demel]

Hi,

I'd like to point out that we maintain a guide on "How to ask questions"
https://wiki.gnuradio.org/index.php?title=ReportingErrors

I'd like to point to our netiquette because of multiple similar postings 
to the mailing list.


Specifically in your case, please share more information on
- what you want to achieve exactly?
- what have you already tried?
- Which resources have you consulted before?
- How is your case different from prior discussions?

e.g. I remember discussions on CSV files and how appropriate they are 
for IQ sample storage. Generally, CSV files are a really bad choice to 
store IQ data.


Cheers
Johannes

Description: S/MIME Cryptographic Signature

Is it possible to update the 'QT GUI Label' when flowgraph is running ?

[Kimmo Lehtinen]

Hi 

I have the following setup in GRC:
1) I use the 'Import' block to import Python functions.I have a file 
my_functions.py which contains several functions, like function_a, function_b 
and so on. In the 'Import' block I have 'import my_functions'.

2) In the 'Variable' block the 'Value' parameter is calculated as
my_functions.function_a(parameter_1, parameter_2,..., parameter_n)The ID of 
this variable is 'variable_a'

3) I use the 'QT GUI Label' block to have a label widget for this variable

This works fine. 
However, I would like to update the QT GUI Label when the flowgraph is running. 
Thus, I am trying to use the 'Function Probe' block with the following setup:
ID:  function_probeBlock ID:    
variable_aFunction Name: my_functions.function_aFunction Args:   
1,2,3,4...

But then 'Function Probe' complains that 

Param - Function Name(function_name):
    ID "my_functions.function_a" must begin with a letter and may contain 
letters, numbers, and underscores.
If in the 'Function Probe' block I haveFunction Name: function_a
the flowgraph runs but there is an error:
val = self.function_a.function_a(parameter_1,...,parameter_n)
AttributeError: 
'numpy.float64' object has no attribute 'function_a'
What is the correct way to use 'Function Probe' block in this case ?Or is it 
even possible ?
I am using  GRC 3.9.5.0 (Python 3.8.10)
cheers, Kimmo

Hi, everyone!

I am working on enabling gnuradio to run faster on the browser through `simd on 
wasm`.
I will post weekly updates in this thread. The following is from last week:

Short version report:
Later plan:

1. Develop those missing components in gr-web (making it more extensible)

2. To support `simd on wasm` this project will go slow pace.

Hi, everyone!

I am working on enabling gnuradio to run faster on the browser through `simd on 
wasm`.
I will post weekly updates in this thread. The following is from last week:

Short version report:
Has Done:
   1. Building debug mode `CPython`.
2. Compare the `webapp` directory output files. (not fully finish)
3. Use `wasm2wat` to ensure `volk` is really under `wasm-simd`.

Delay and TODO in this week:
2. Compare the `webapp` directory output files.
4. Enabling open and save files for user-selected paths in gr-web.

Hey, all!



This is a weekly update email about the GSoC project.



Following is last week progress and next week plan:

Short:

*  Has Done:  building gr-web wholly and play grc.

*  Need to be Done: Intend to run a benchmark to measure different implement to 
`volk`

Hi, everyone!

I've been accepted to work with GnuRadio for this year's Google Summer of Code.



The task I intend to implement is porting SIMD code to gr-web through wasm,

which enables gnuradio more extensible and popular through the browser.



I am really sorry, this post seems a bit late due to so

Dear Yao,

It would be great to see an example web browser for
a simple SDR, like an RTLSDR.
