I was recently conducting some trials on some custom C++ software for data acquisition on the BioSemi ActiveTwo and I came up with a peculiar problem. When I use the USB receiver with the eye tracker hardware the sync byte is nearly always out of sync. With the same code and using the USB receiver w...

That is perfectly clear. Thank you for clarifying BioSemi's position on the matter. I think the requests are perfectly reasonable for any one wanting to write the Linux driver. As stated it would have to be a community project with little involvement and support from BioSemi.

[quote] We do not plan to make the source code of the Windows driver available because of competitive reasons. [/quote] I think then your mission statement should change on your home page. Since you state: They are optimized for this specific application by offering features like: freely configurabl...

Ok after searching the whole forum and analysing the header file I think it is as follows

The value translated is say 8388607

For electrodes
Cal=0.0312
Offset=-0.4844

Foir Status and event signals
Cal=1
Offset=0

On electrodes
So (8388607*Cal)+Offset=261724.054 microvolts ?

Hi I am trying to write a small prog to read data from a socket transmitted using your actiview server. I understand in what order the channels are transmitted and that the samples are 3 bytes long and little endian. So: For 8388607 byte_buffer[0]=-1;//Last element byte_buffer[1]=-1; byte_buffer[2]=...
