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.
[
KeyPressed,
EventTime] = FORPWait([Seconds])
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.
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
free to let me know:
