[Lab] Higher speed (8.0 Mbps) I/O interface with PC

[Paul & Andrea Mumby]

Another option would be to put a small micro in between your circuit and
your PC as an interface buffer. Something with native USB support.

Stream the data directly over an 8 bit wide parallel digital interface to
the micro (or hell 16 or 32 if you have enough pins) and stream it out over
USB using the micro.
