Ok, I will look into using the GRC as a first step. I am hoping to work with the USRP eventually. If someone knows some up to date tutorials specifically for USRP that would be appreciated as well.
I see now that the mc4020 code was intended to gather the FM from a cable modem over a parallel port. That is not general code or USRP code at all. The info at: http://www.joshknows.com/gnuradio ...does have some gnuradio + USRP specific code, but it's very short. Maybe I can figure it out by looking at that along with the "how to write a signal block" page. Thanks, Dave On Sat, 09 Jul 2011 17:21:52 -0400, Marcus D.

I found a page on joshknows.com: http://www.joshknows.com/gnuradio ...this clears up the gr.flow_graph() error (should be gr.top_block() ), but can find no info on getting the mc4020 FM tuner example to work. That is a shame as it was interesting. I'm not sure where to go. The MC4020 example was unrelated to USRP1 in any way as far as Iknow.

My ultimate goal is to emulate 802.15.4 in USRP (which has been done before) and test some variations in the MAC layer. For now, I just need to learn gnuradio though! -Dave Many thought experiments can be conducted using Gnu Radio Companion(GRC), which gives you a graphical, Lego-Like > way of assembling and re-assembling flow-graphs. > > You could start here: > > http://www.csun.edu/~skatz/katzpage/sdr_project/sdr/grc_tutorial1.pdf > >-- Marcus Leech Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org -- Open WebMail Project (http://openwebmail.org)
