Joystick direction as response & RT

[Nick]

Hi everybody,

I am trying to interface a Logitech Attack3 joystick with E-Prime. So
far I have only had limited success although I think it should be
pretty simple to do what I need.

On each trial, the participants will have to respond to the final
slide with a forward or backward movement of the joystick (depending
on the trial type). All I need is 1) for E-Prime to record the
Reaction Time of when the the push or pull of the joystick is
initiated (in correspondence to the onset of the final slide for each
trial) and 2) for the direction (up or down) of the first joystick
movement to be recorded to the data file.

It seems like this should be pretty standard, but I can't find any
code that addresses it. Is there some code you might know of to do
this type of thing?

Also, I did read through previous posts attempting to solve this
problem with continuous sampling of the joystick X-Y coordinates, but
I couldn't get the posted code to work out.  Although I don't like
this solution quite as much for my purposes, any help with how to
continuously sample the X-Y coordinates would also be very
appreciated.

Thanks!
Nick
