 		 #111569 - 10MHz?
Responding to: ???'s previous message
Richard Erlacher said:
That's why I was suggesting the use of that FTDI DLP245UM USB-FIFO adapter. It comes with a pretty simple-to-use driver and looks, at the target end just about like a FIFO, since that's what it is. It only operates at 10 MBytes/sec, but even if you sample at 200 MHz, transfers at 10 MB are pretty adequate.

It barely would transfer 10MBytes per second, being an USB Full speed device... 1MBytes/s sounds much closer to the reality.

Nevertheless, not a bad option.
