Hi,I have an OOT module that takes in vectors of length A and outputs vectors of length C using the following:
Constructor:
my_module_impl::my_module_impl (int A, int C, ...)
: gr::sync_block("my_module",
gr::io_signature::make(1, 1, A*sizeof(gr_complex)),
gr::io_signature::make(1, 1, C*sizeof(gr_complex)))
Work function:
int my_module_impl::work(int noutput_items,
gr_vector_const_void_star
&input_items, gr_vector_void_star &output_items)
{
const gr_complex* in = (const gr_complex*) input_items[0];
gr_complex* out = (gr_complex*) output_items[0];
int i;
for (i = 0; i < noutput_items; i++) {
...
memcpy(out, my_output, C*sizeof(gr_complex));
in += A;
out += C;
}
return(noutput_items);
...
At run time, I get a
ValueError: itemsize mismatch: my_module0:0 using 524264,
vector_to_stream0:0 using 294912
where the first number 524264 is not what I am expecting it to be which should be the same as the second number. Specifically, A=65536 (524264=8*(A-3)) and C=36864 (294912=8C).
Am I doing everything correctly? Thanks! Grace -- Grace K. Yeung, MS NorthWest Research Associates 301 Webster Street Monterey, CA 93940 gr...@nwra.com https://www.nwra.com
