This is a quick example derived from some code I use when I want to
just capture random data for post processing.

All it does is open both daughtercards and save the stream for a set
amount of time. Transmission just as simple; it is the opposite, but
I don't really have anything sanitized to share with you right now.
I'll put it on my 'to do eventually' list.
Remember that there is a fixed phase offset between both channels
because of the un-linked accumulators in the ADCs. My 'to do
eventually' list also has 'write fpga image w/o this offset', but for
now you will just have to account for it when you develop.
