Hi,
I'm wondering if it is possible to make an output of a block that is a
vector of a vector.
I tried with:
int
vector_source_tagged_impl::work(int noutput_items,
gr_vector_const_void_star &input_items,
gr_vector_void_star &output_items)
{
std::vector *optr
Does the number of channels have to be a power of 2?

I have a custom block that is adding the "burst" "True" and "False" tags
via:
add_item_tag(0, d_total_passed_samples, pmt::mp("burst"), pmt::mp("True"));
and
add_item_tag(0, d_total_passed_samples-1, pmt::mp("burst"),
pmt::mp("False"));
When I run it and look at the output via Tag Debug, I see

Hi Alice - Inside "work" or "general_work", all you have is access to is
pointers to buffers. The "shape" of them is inferred by the block
implementation specifics, for example a pointer to unsigned char array,
or pointer to float array. Recasting pointers as you describe will cause
a crash, becaus
Everything is now clear!
Thank you for the patience and sorry for my little knowledge.
Thanks to rear1019, Marcus and MLD

Hi Marcus --
First, thanks for catching the typo in the channel map. There was no
plan to skip any channels; the goal is to get each channel in frequency
order (out0 = 540 kHz; out116 = 1700 kHz).
I did an experiment using a signal generator feeding the Red Pitaya
receiver and testing vario
And the resampler did the trick. Carriers are now nicely aligned. Thanks
again!

Hello Neel,
Sounds great!
Do you have such workshop plans in Europe, probably in France/Germany.
Recently I attended the NI workshop on the same during ICC 2017 Paris, but
due to some reasons the agenda was not covered during the workshop. And it
was very short also.
I am very much interested in
