Hello Achilleas,

Hi All,
I've tried to add a new variable to an existing block,
gr-noaa/noaa_hrpt_deframer, and hoped it would show up in GRC.
I've modded the noaa_hrpt_deframer.cc and noaa_hrpt_deframer.h in directory
lib, noaa_hrpt_deframer.i in directory swig and added
the new variable + callback into grc/no

Hi everyone,
I want to ask a question about the file source block on GRC. It reads
the .bin files and takes them as input. But Should that .bin files be
in a fixed format. I mean is there a fixed format for this block to
read or does it reads any kind of .bin files.
I am trying to set a .bin file
The file source reads binary data out of a file and writes it into a
gnuradio stream. So, if your data stream is floats, the file should be
filled with floats, as it would be in your computer's memory.

Hi Guys,
I have done the following steps on my Ubuntu10.04:
git clone http://gnuradio.org/git/gnuradio.git
./bootstrap,
./configure,
make and
sudo make install.
All still seems to be OK.
However, I run

Hello Zhang,
export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python2.6/dist-packages
should probably fix the error. Make sure the path specified above exists and
contains the python gnuradio packages.
Cheers,

Hi Rakesh
Thanks a lot.
The grc have run after adding the PYTHONPATH.
I tested the grc using the simple blocks:
--> -->
(Accessories is Capture Screen )
And then press "Execute " button
Howerver, I can't see the waveform.
Why?

Hi Josh,
Thanks for the answer. But my problem is not exactly about the subject
you answer. To make it clear i will simply specify my problem.
I set an array on matlab which includes non-integer values (like
0.001, -0.253, ...) and form a binary file by using fopen, fwrite
commands then obtain a
The non-gl scope sink is a little weird. You may have to mess with the
time axis to see anything. If you install python-opengl, you will get
the gl scope sink which works much better. Looks like this:

More information about my problem.
GRC tells me:

After running the USRP2 GNU Radio example "usrp2_wfm_rcv.py" I got an error

Many thanks in advance.
