[Discuss-gnuradio] Gnu Radio Profiling Questions
Hello. I built gnu radio using the cmake -DENABLE_PERFORMANCE_COUNTERS=True on Ubuntu 14.04.4 32-bit. I then did a 'sudo make install'. When I run gr-ctrlport-monitor I get the following error: e@ubuntu:~$ gr-ctrlport-monitor Traceback (most recent call last): File "/usr/local/bin/gr-ctrlport-monitor", line 28, in from gnuradio.ctrlport.GrDataPlotter import * File "/usr/local/lib/python2.7/dist-packages/gnuradio/ctrlport/GrDataPlotter.py", line 26, in from gnuradio.ctrlport.GNURadio import ControlPort ImportError: No module named GNURadio Is there a good Wiki page on setting up profiling?

So a 'sudo ldconfig' fixed the problem. On Tue, Apr 26, 2016 at 7:20 AM, Yile Ku <stiffst...@gmail.com> wrote: > I am running Ubuntu 14.04 and used pybombs to build gnuradio.

[Discuss-gnuradio] Parameters for Source Block
Got the source block working. Thanks for the help. Is there a standard way to add parameters to a source block? I notice in gnuradio-companion you can right click on the block and it has parameters that are settable for that block. I need to reference external parameters such as frequency and sample rate also.

[Discuss-gnuradio] I Q samples in a source module
My source modules has 16-bit I Q samples that are interleaved: I,Q,I,Q,I,Q... as signed 16 bit values. I generate 512 pairs at a time in my work function (C++). I set noutput_items to 512 and copy I and Q out 512 times to the output_items variable in the work function. Is this the correct format of data that subsequent modules can expect?I use the IShort_to_Complex module to convert the samples for subsequent modules.

[Discuss-gnuradio] Module not showing up in companion
I have built a custom source module. I followed the steps for coding and did a make, make test, make install. Then I did the gr_modtool makexml my_mod, and a 'make install again. I can see the module in /usr/local/share/gnuradio/grc/blocks/my_mod.xml. When I run gnuradio-companion I can find the module when I search. I am running gnuradio-companion 3.7.6.1.

[Discuss-gnuradio] I Q channels in source module
I am writing a source module/block and I generate 16 bit signed I and Q
values. There is first a 16 bit I value then a 16 bit Q value repeated
1024 times.
In my source module I have:
usbradio_impl::usbradio_impl()
: gr::sync_block(usbradio,
gr::io_signature::make(1, 1, sizeof(short)),
gr::io_signature::make(1, 1, sizeof(short)))
{
state = 0;
cnt = 0;
set_max_noutput_items(1);
set_max_output_buffer(2);
}
/*
* Our virtual destructor.
*/
usbradio_impl::~usbradio_impl()
{
}
int
usbradio_impl::work(int noutput_items,
gr_vector_const_void_star input_items,
gr_vector_void_star output_items)
{
short *out = (short *) output_items[0];
// Do +signal processing+
stuff_output(out);
// Tell runtime system how many output items we produced.
return 1024;
}
The stuff_output(out) function will stuff an I value then a Q value 512
times.
Is that the correct way to present I Q values?
Thx,
Y-
