You can read the input from both channels over the serial USB line (/dev/tt=
yUSB0 or something)=2E There are synchronisation messages in each packet (s=
omerhing around 15 lines), and some more info whose meaning I can't remembe=
r=2E But basically what you need is the value of the channels in this speci=
fic frame=2E
They might each come over two lines, least significant and most significan=
t bytes=2E They should be the only ones that change over succeeding packets=
, except for the packet number, which should increment from one to the next=
=2E
Then, you can do whatever you want with that=2E Should be sampled at 256Hz=
, which is quite enough for EEG=2E
Let us know if you can't make it out, I may give further explanations if n=
eeded=2E Haven't used it for a while, but it's not far away, physically spe=
aking :-)
Good luck !
