LSL application for the viewpoint eye-tracker system. Designed for x64 bits windows systems only.
This LSL application is a python package. It can be installed with pip
from source:
pip install git+https://github.com/fcbg-hnp-meeg/lsl-viewpoint
This LSL application requires 2 configuration variables: the path to
VPX_InterApp_64.dll
and the set sampling rate. The VPX_InterApp_64.dll
should be the
one in use by the ViewPoint application. Both configuration variables can be set with
lsl_viewpoint.set_config
:
from lsl_viewpoint import set_config
path = "C:/Applications/Arrington/VPX_InterApp_64.dll"
sfreq = 60
set_config(path, sfreq)
The configuration variables are saved in a file ~/.lsl-viewpoint
.
The stream of data starts as soon as the module lsl_viewpoint.callback
is imported.
Thus from lsl_viewpoint.callback import VPX
will start the streaming. It is not
recommended to ever import the callback
module. Instead, the entry-point
lsl_viewpoint
should be called in a terminal:
lsl_viewpoint --help
