If you've downloaded the code for GNU Radio, you have all the code that goes in the FPGA. usrp/fpga/top_level/usrp_std/usrp_std.v is the top of the design. The stuff you're looking for is in usrp/fpga/sdr_lib For schematics, see http://www.gnuradio.org/trac/wiki/USRP Eric _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
