Obtaining data from various hardware devices
1 post • Page 1 of 1
We are trying to configure two gUSBAmps using Gipsa's gUSBAmp driver in OpenViBE 2.2.0. Both of them are connected via this gtec's master/slave dongle. The master one is set in the Gipsa driver preferences. We then pick up the signal using the acquisition client in the Designer and visualize it using simple signal visualization box. We have all 32 channels showing up but unfortunately, only half of them show EEG data - the other 16 just show random noise. (But they do react when we try to turn on and off the corresponding GammaBox of each gUSBAmp). At this point, we are not sure what the problem could be. It seems like Gipsa's driver should do it, but we just could not find a guide on how to properly set up a master/slave configuration using this driver in particular.
