Samuel,
I would be interested in you code. I plan to buy some of the hardware you mentioned and set something up for a teaching lab.
Thanks.

But the code is really dirty.
I have tested it with a usb2 Mesurment Computing Card.
It works quite good for low sampling rate (16 channel 200Hz) and small
window (5s.)
And I am doing something else at the same time (recording to a file and
trigger detection)
So for me mpl is good enough too.
What is the size of data you to refresh 5 frames per second ?
