Hi, all
I met a problem when I tried to read data from USRP. I hope someone can help
me. Thanks.
Here is my flow graph:
source_c --> keep_one_in_n --> g.head --> gr.complex_to_mag -->
gr.vector_sink_f
if __name__ == '__main__':
tb = top_block()
try:
tb.start() # start executing flow graph in another
thread...
time.sleep(1)
main_loop(tb)
except KeyboardInterrupt:
pass
In main_loop function, I read data from vector_sink_f.
def main(tb):
while(True):
time.sleep(1)
data = tb.dst.data()
But when I print data, the result shows that data doesn't change at all. I
don't why. In my opinion, data should be updated as the flow graph runs. And
that changing data with time is what I wanted. Does anybody know the reason?
Thanks!
Ally
