Greetings, I would like to ask you how to read the data stored in a vector sink. I tried the solutions I found in the discussion list. You can see some part of my python code below. ------------------------------------------------------------------------------------------------------------------------------------------------------ ################################################## # Connections ################################################## self.connect((self.my_vec_src, 0), (self.my_thro, 0)) vector_source -> throttle self.connect((self.my_thro, 0), (self.my_h, 0)) throttle -> head self.connect((self.my_h, 0), (self.my_vec_snk, 0)) head -> vector_sink
time.sleep(10) my_data=self.my_vec_snk.data() print "data: ",my_data -------------------------------------------------------------------------------------------------------------------------------------------------------- if __name__ == '__main__': parser = OptionParser(option_class=eng_option, usage="%prog: [options]") (options, args) = parser.parse_args() tb = top_block() tb.Run(True) ---------------------------------------------------------------------------------------------------------------------------------------------------------- Output of the program : data: () I need to read an incoming data to correlate with some predefined data, vector. If I am not wrong the best solution is to save data in a vector sink same length as the predefined vector, then applying the cross-correlation to them. The program above is just a test program to examine what the vector sink stores, but I am confused why it does not work, because I saw a similar working use of a vector sink with USRPs. I already save the data in a file, but it does not seem to me as a good solution at least due to possible memory waste, though clearing the file is possible in run-time. Thanks in advance, Abdullah
