Hello,
We are using a DirectIn input device of empirisoft, with Delphi 2006 and Matlab 2006b software for our experiments.
As we learned lately, USB devices are polled by MS-Windows at 125 Hz rate (every 8 MSec).
Is there a way to eliminate this 8 MSec timing uncertainty in measuring reasponse time ? (We are interested in 1 MSec resolution).
Sincerely,
