Hi Matt, I modified the usrp_std.v file to make connections to the debug IO pins and then on my PC tried to compile the project using Quartus II software. The compile went successfully, but later when I opened the Pin-Out file under Compilation Report all the signals showed at 3.3V-LVTTL. I had only clicked on the play button after opening the .qpf project. I would like to know if the default settings are still all 3.3V LVCMOS and I inadvertently changed something. If not, I would like to set the 16-bit debug pins to LVCMOS since I am trying to attach a CMOS cable to the pins on basic RX. Could you recommend a way to do this? Do I have to look at IO banking rules etc.? I have some FPGA background but not a whole lot.

I don't have Quartus II installed yet. Is there a way to find out or set this through Python? > 3.3V LVCMOS _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
