Great, thanks guys!! Best regards, Henrikke

As you'll see I have included the scale factors, but I'm still unsure if they should be used. In the code samples (https://brainflow.readthedocs.io/) there were no scale factors, but OpenBCI docs (https://docs.openbci.com/docs/02Cyton/CytonDataForma…

I managed to get some help and we used the code example you provided to send data in chunks. So the following script works. import argparse import time import numpy as np import brainflow from brainflow.board_shim import BoardShim, BrainFlowInpu…

Thanks, and thanks for letting me know. Hope all goes well with you and your family!

I was made aware of that get_current_board_data() doesn't remove samples from the buffer, so I'm pulling the same sample repeatedly. They suggested to use get_board_data() . However, when I use get_board_data() I'm not getting any data. It is all e…

That would be great! I really wanted to fix it as a learning experience as well. This is basically what I have been trying to do for the past four days.

Hm, ok. When in default mode I still get the traceback I mentioned (also below). I don't know why or how to fix it. I'm sorry, but I don't know what to make of the example that sends data in chunks. I would like to send data continuously. Traceba…

@retiutut said: You need the Cyton in default mode to get values from the Accelerometer. Analog and Digital signals are not what you want. When I tested analog mode (the code in the original post), the accelerometer data seemed to be corr…

I will have another look and go at it. I'll ask the LSL community as well, and see if they have any suggestions. Thanks! No problem uploading a version of the code to a OpenBCI repo, but I have to get it working first

Also, I noticed the documentation says EEG data are returned as uV (https://brainflow.readthedocs.io/en/stable/DataFormatDesc.html?highlight=uV#units-of-measure), so I assume this means the scale factor is not needed? What is the unit for accelerome…

I also changed the sampling rate of the LSL accelerometer stream to 25 Hz (line 49 above), but this did not change anything. Still the same traceback.

@retiutut said: Lines 58 and 59 are probably not correct.... I think.... Take a look at this python code used for testing purposes: https://github.com/OpenBCI/OpenBCI_GUI/blob/master/Networking-Test-Kit/LSL/brainflow_lsl.py I think …
