I have 5 blocks in my flowgraph:
USRP Src -> PFB Decim by 2 -> Mult 32768 -> Cplx-iShort -> FileSink
I am running 14 MS/s x 2 x 32 bits from the USRP, 7 MS/s x 2 x 16 bits
to the disk.
Previously, even setting the USRP num_recv_frames=512 or 1024, it
would run for about a minute fine then print 1-4
Hello Marcus,
I went looking at the code and I found this:
d_fftsize = (int) (2 * pow(2.0, ceil(log(double(ntaps)) / log(2.0;
d_nsamples = d_fftsize - d_ntaps + 1;
set_output_multiple(d_nsamples);
which I'm not sure I understand, but is in agreement with what I
observe. Can someone explain t
I've had a similar problem when I generated files for my own module
using the gr_modtool and then copied some existing code by replacing the
file(s) that gr_modtool generates. It turns out I had overlooked that
the new "my_block" name needs to be changed in several places, like the
namespace de
Hi Marcus,
Thank you for your reply.
The source files are added to the CMakeLists.text files. But they are not
added by my self, they are added when I use "gr_modtool add -t general
my_block" and "gr_modtool makexml my_block" to make a new block and xml
file.
Only the my_block.h file in include
Hi Su Li,
have you added the new source files to the CMakeLists.txt in lib,
include and grc?
Do these block have the YOURMODULE_API property?
Best regards,
Marcus

Hi Daniele,
alignment requirements for the FFTw aren't that strict, but you'll have
to wait for a decimation*ntaps of samples to accumulate before you can
do the FFT.

Marcus

Dear All,
I am trying to make an out of tree module by following the tutorial on Gnu
radio website. I can write simple blocks in C++, compile it and install it
to it usable in Gnuradio company.
But for some complex block, I want to implement them based on the gnuradio
build-in blocks, for example
