The Driver did not show the data in real time
Posted: Fri Mar 18, 2016 1:01 pm
Hi,
I have created a OpenViBE driver for our own EEG amplifier and it worked successfully for a long time
However, recently there always is a delay when I receive data from the amplifier through the driver. The driver did not display the data in a real-time way as before, instead it seems to be stuck for 3 to 5s ,and then pump out data which could be easily noticed via the dark blue bar in the GUI of the driver or via the signal display toolbox in the designer.
But it did ont mean the driver skiped some data, the data seems to be completed because I got the right wave when I turned on the "square wave" mode for our amplifier. It also seems that the data has been sent to the platform in time because I made it report everytime after it was sent and the report seems right.
So,this situation really confuses me a lot and I don't know how to fix it.Could you please give me some help?
Regards
