Beware that any tutorials, forum answers and plugins you find online may no longer be compatible with your version, so always check the date and official documentation.

The DataHub Makes use of the lab streaming layer. The lab streaming layer (LSL) is a system for the unified collection of measurement time series in research experiments that handles both the networking, time-synchronization, (near-) real-time access as well as optionally the centralized collection, viewing and disk recording of the data.

==Installation==
==Installation==
Our support for LSL is mainly done in python. Download python here: [https://www.python.org/downloads/release/python-376/ Please choose a 64 bit version.]. Run the installer and make sure to add Python to the file path (it's an option in the installer).
Open a command prompt, start with upgrading the pip installer by typing:<br/>
<code style="background-color:#000; color:#fff; padding:1px 3px;">c:>python -m pip install --upgrade pip</code><br/>
Then:<br/>
<code style="background-color:#000; color:#fff; padding:1px 3px;">c:>pip install pylsl</code>

===Versions===
The TSG uses the version 1.15.0. Open a command and type the following to find the version used:
<code style="background-color:#000; color:#fff; padding:1px 3px;">c:>python</code><br/>
<code style="background-color:#000; color:#fff; padding:1px 3px;">>>> import pylsl</code><br/>
<code style="background-color:#000; color:#fff; padding:1px 3px;">>>> print(pylsl.__version__)</code><br/>

A short example for sending lsl streaming data:
<syntaxhighlight lang="python" line>
#!/usr/bin/env python
import threading
from pylsl import StreamInfo, StreamOutlet
def getData():
while running:
buffer_in = getSensorData()
send_data = True
time.sleep(0.001)
info = StreamInfo(
name='MyStream',
type='COP',
channel_count=4,
nominal_srate = 200,
source_id='BalanceBoard_stream'
)
outlet = StreamOutlet(info)
threading.Thread(target=getData).start()
while running == True:
if send_data:
outlet.push_chunk(buffer_in)
send_data = False
</syntaxhighlight>
A short example for receiving lsl data:
<syntaxhighlight lang="python" line>
#!/usr/bin/env python
from pylsl import StreamInlet, resolve_stream
==References==
streams = resolve_stream('name', 'MyStream')
#streams = resolve_streams()
==External Links== <!-- Optional -->
inlet = StreamInlet(streams[0])
while True:
sample, timestamp = inlet.pull_sample()
print(timestamp, sample)
</syntaxhighlight>
