Can I enable the eyetracker in the API?

Post by Kazzim » Wed Feb 13, 2013 10:46 am


When using the API for collecting data I can't get any data from the Jazz Eyetracker. Do I need to set a flag to enable the Eyetracker?

These are the numbers I get when I run it. The values for the data is not correct. I just want to see that the channels are open. I read in an other thread that ringbuffer[266] to ringbuffer[281] are the sensors. And when I counted the remaining channels after the Auxiliary sensors I thought that the remaining channels was the eye tracker but they returned 0 except 279. Then I thought that I might need to activate the eyetracker like I have to do in the ActiView. Can I activate it?

Ringbuffer nr:
A4 Value: -2125856512 Ringbuff: 6

I am using fieldtrip application from donders institute to acquire data, but I also have no data in je JAZZ eyetracker channels, while the other channels are fine.

Is there an enable bit flag somewhere to enable the online acquisition of the JAZZ eyetracker data through the API?
