Is it possible to use a spare pin on the USRP (say, for example, on a daughtercard) as a signal sink?
In other words, if I have a char signal stream in software, in which only the bottom bit of the 8 bits is active, how do I get that bit back out into hardware-land?
Many thanks for your time (even if the answer is "no, there's no easy way to do it, short of writing custom vhdl...").
