FORPWait Checks for the specified amount of time, if a button of a FORP device
(tested for HH-5-CYL) is pressed , returns if a button has been
pressed or specified amount of time has passed.

Usage:

[KeyPressed,EventTime] = FORPWait([Seconds])

Arguments:

Seconds Maximum time to check for buttonpresses in seconds.
Default’s to ‘wait forever’ if not provided.

Returns the keycode (KeyPressed) of the pressed button and the
time (EventTime) of the status check.

KeyPressed KeyCode of the Pressed Button or empty value if
waiting timed out without any key press.

EventTime Time of keypress as returned by GetSecs.

IMPORTANT NOTE:

Current-Designs FORP Device (HH-5-CYL) does not return any values for
manufacturer or product, so i used the VendorID returned by
PsychHID(‘Devices’) for the HH-5-CYL.(ATM i do no really know if the
VendorID has unique values).
Another issue i had to solve was a ?bug? using ‘GetReport’. I had to
close the Callbackhandlers to the current device by calling
‘ReceiveReportsStop’ before calling ‘GetReport’ on another device.
If you have got any advice for a better way solve those problems, feel
