Thanks for the link. I'll study the file to learn more about writing GNU radio apps in c++. I noticed that this was the only example in the c++ directory.

Thanks for finding that. It seems be a python2.5 vs 2.6 issue where tuples dont have a .index method in python2.5 Its fixed in the trunk.

[Discuss-gnuradio] usrp2 fpga testbench
Hi everyone, Since we try to improve the ddc performance, (see http://lists.gnu.org/archive/html/discuss-gnuradio/2009-06/msg00075.html) I have to simulate my modifications to the FPGA. Is there any testbenches for the complete system? I've found single_u2_sim.v, but when I simulate this file the flash.rom file is missing. Should this file contain the binary firmware that is loaded during boot? Can anyone give me some hint how to simulate the entire system, I'm using windows with ISE simulator?

Can you please elaborate a bit more...? Where does the > correlations takes place within the python code. The framer sink is a block implemented in C, which is why there is no python code for it, the actual correlating happens in gr_correlate_access_code (also implemented in C), they are connected together to do the demodulating in pkt.py, which is modulation independent. (from: http://gnuradio.org/trac/browser/gnuradio/trunk/gnuradio-core/src/python/gnuradio/blks2impl/pkt.py) 141 self.correlator = gr.correlate_access_code_bb(access_code, threshold) 142 143 self.framer_sink = gr.framer_sink_1(self._rcvd_pktq) 144 self.connect(self, self._demodulator, self.correlator, self.framer_sink) correlate_access_code takes a stream of bits from the demodulator and tries to find the code prepended to each packet, when it does it sets the second LSB (because each demodulated bit is in the LSB and the other 7 are 0). The framer_sink_1 watches for this flag and blindly collects the packet starting from that point. If you want to get a better idea of what's happening and understand C you can look here: http://gnuradio.org/trac/browser/gnuradio/trunk/gnuradio-core/src/lib/general/gr_correlate_access_code_bb.cc http://gnuradio.org/trac/browser/gnuradio/trunk/gnuradio-core/src/lib/general/gr_framer_sink_1.cc (Note that if you have an old version of the trunk checked out you might be better off looking at those files in your local repository) Jason ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio

These are a good place to start getting to know gunradio and the USRP, most of the examples deal with the USRP1, but it should be fairly simple to transform them using the examples in the appropriately named 'Examples' folder from the gnuradio trunk. http://gnuradio.org/trac/wiki/GettingStarted http://www.gnu.org/software/gnuradio/doc/exploring-gnuradio.html http://www.joshknows.com/gnuradio Jason ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
