Notes about the OpenEEG data format

It's actually not quite so easy to glean information on the data format at OpenEEG (unless I'm missing something). These notes and links may help.

The data (packet) format we get off our digital boards is called "p2" (packet format 2).
Details are under "Firmware 2" right at the bottom of the
main Modular OpenEEG page. This is the format of our data.

This link has it formatted better. Also see Tim's blog.

We are only using channels 1 and 2 (i.e., not 3-6). Note each channel is allocated 2 bytes; a high byte and a low byte. 10 bits of these 16 bits record the signal values (ie. we would expect the upper 6 bits to be zero).
