How to solve the problem of device drift? #16

Open CAY1300 opened 4 years ago

CAY1300 commented 4 years ago

I used the EPOC+ to collect the raw EEG data, when I connected to openvibe-aquisition-server and click "play", the device drift showed in the bottom is around 5000ms, and I increased the sampling rate to 256Hz and change the packge sending parameter to 032 instead of 004, the device drift is decrease to about 100ms, but it can't be lower whatever I have done, so ,is this number correct or there are some other solutions? please help me with this issue, thank you in advance!

you might check this link at the bottom, to stream for 001 packets.

i think theres always going to be some amount of device drift though.
