Hello All,
I’m trying manage a vector of 10528 bytes, I made a C++ routine and
works
but, when I work with my routine in GNU Radio, It do really extrange
things
and I don’t know why. I try to explain:
My Routine in GNU is:
ex_scramb_ss::general_work (int noutput_items,
gr_vector_int &ninput_items,
gr_vector_const_void_star &input_items,
gr_vector_void_star &output_items)
{
const unsigned char *mpeg2package = (const unsigned char *)
input_items[0];
unsigned char *mpeg2packageout = (unsigned char *)
output_items[0];
unsigned char result
;
printf (“hello”);
for (short i=0;i<10528;i++){
result=mpeg2package[i];
…
…
…
}
}
And my test in python is:
from gnuradio import gr, gr_unittest
import ex
class qa_ex (gr_unittest.TestCase):
def setUp (self):
self.tb = gr.top_block ()
def tearDown (self):
self.tb = None
def test_001_escramb_ss (self):
src_data=(0x47, 0xA7, 0x15, 0x38......(10528))
src = gr.vector_source_b (src_data)
dst = gr.vector_sink_b ()
sqr = ex.suma_ss ()
self.tb.connect (src, (sqr,0))
self.tb.connect (sqr, dst)
self.tb.run ()
result_data = dst.data ()
if name == ‘main’:
gr_unittest.main ()
Ok, I put printf(“hello”) and hello is printed 4 times and I don’t know
why,
only I connect one time my block, besides, when I print mpeg2package[i],
my
entry, is printed 4 times and with diferents value (71 0 0 184), this
isn’t
sense because I don’t modify, and I can’t, my entry
