I'd like to use a Cedrus Response Pad RB Series for collecting response and timing data. I want to use it to replace simple keystrokes, but am not sure where to get started. Is there any documentation for using this with Vizard? Thanks.
You can use the vizcedrus module. To connect to the pad use the following:
#Connect to cedrus pad
import vizcedrus
vizcedrus.open() #Default: port=1 , baudRate=19200
Then you can register callback functions for button events:
#Setup cedrus callbacks
def cedrusButtonDown(e):
print e.button,'button down'
def cedrusButtonUp(e):
e.button,'button up'
viz.callback(vizcedrus.BUTTONDOWN_EVENT,cedrusButt onDown)
viz.callback(vizcedrus.BUTTONUP_EVENT,cedrusButton Up)
