OpenSesame Plugins for communication with the RUG/BSS Event Exchanger and Event Exchanger derivatives hardware.
The currently supported OpenSesame version is v3.3
The following plugin collection is available:
| Plugin | Description | Status |
|---|---|---|
| EVTxx | Event Exchanger variants | not validated |
| ResponseBox | Button response box variants with 1-4 buttons | not validated |
| RGB_Led_Control | not validated | |
| TactileStimulator | Tactile Stimulator 0-5mA | validated |
| VAS | not validated | |
| VAS2 | not validated |
The plugins are dependent on the Python module pyevt and the underlying HIDAPI package.
https://pypi.org/project/hidapi/
pyevt and hidapi are installed from the Python Console in OpenSesame with a single command:
!pip install --user pyevt
The plugins (and the cloned git) could be placed in the user space e.g.: C:\Users\username\Documents\OS_Plugins\evtplugins\EvtPlugins\OpenSesame_Plugins
For OpenSesame to find this location, the user must create an environment.yaml file in the OpenSesame program directory. See for the instructions here:
