Davide, In the code that we distribute, yes. However, I think you're asking about the code that you have been modifying in the FPGA. You're in charge of that part. What are you doing? In the unmodified code, we push 16-bit I & Q across the interface to the FX2 and from there to the host. The data comes out I first, then Q, and each 16-bit value is little-endian byte order. Hope this helped. Eric _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
