The daughterboards are automagically constructed for you. You can access them using u->selected_subdev, or the lower-level db() method. I suggest filling in the usrp_subdev_spec structure and using u->selected_subdev to retrieve a shared pointer to the daughterboard. Use u->determine_rx_mux_value to calculate the appropriate daughterboard specific mux value, then set the mux using set_mux. Finally, tune using bool ok = u->tune(0, db, target_freq, &result) See: http://gnuradio.org/doc/doxygen/classusrp__basic__rx.html http://gnuradio.org/doc/doxygen/classusrp__standard__rx.html http://gnuradio.org/doc/doxygen/group__usrp.html > I'm messing with this because I'm trying to call the > usrp_standard_rx::tune() function, to set the frequency, so I can > avoid jumping through more hoops (i.e. not sure what else needs to be > set to set the frequency properly, if using > usrp_standard_rx::set_rx_freq() and figured this is a better way to do > it all). > > Thank you. > > -- > Cheers, > Timur Eric _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
