Hello group,
I am writing a C++ OOT module in GNU radio operating in vectors of length
1024. So in the .cc file I wrote:
gr::io_signature::make(1, 1, sizeof(float)*1024),
gr::io_signature::make(1, 1, sizeof(float)*1024)),
And in the work function I wrote:
float *out = (float *) output_items[0];
int noi = 1024 * noutput_items;
memcpy(out, input_items[0], noi * sizeof(float)); // just copy input
to output
return noutput_items;
when I connect a "Stream to Vector" block (Num of items=1024, Vec length
=1) to this custom block, it shows "Source IO size 4096 does not match sink
IO size 4".
Where did I make the mistake? noutput_items indicates the num of output
vectors, right?
Thank you if you could give me any help.
Regards,
Wei
