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
Our support for LSL is mainly done in python. Download python here: 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:
c:>python -m pip install --upgrade pip
Then:
c:>pip install pylsl
more info: cross platform pylsl
Versions
The TSG uses the version 1.15.0. Open a command and type the following to find the version used:
c:>python
>>> import pylsl
>>> print(pylsl.__version__)
Usage
Python
<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
