I’m working on FPGA mods to push a little bit of work off of the
computer onto the USRP’s FPGA. If I understand correctly, the right way
to do what I want is to create a new config file (e.g. a modification of
usrp_std_config_2rxhb_2tx.vh) with my changes in the defines.
First, the comment: “// IF RX_ON is not defined, there is no transmit
circuitry built” – that should be `receive circuitry’, yes?
Second, in what applications are multiple receive and transmit channels
are used? They aren’t used in tunnel.py right? I want to be doing RX and
TX on the RFX2400 as in tunnel.py; this application only uses one RX and
one TX channel, so I can define RX_SINGLE and TX_SINGLE instead of the
