I need to send some signals to a device via USB port. The signal needs to switch from 1 to 0 every 45ms or so (the logic of the signal is a bit more complex, but we can simplify it and say that we only send 1 and 0 at every ~45ms).
As Windows is non-real time multitasking, my application will not run all the time (even if I set it as 'real time' priority) so it may not be active when the time lapses and needs to send the signal. I cannot accept a delay higher than 0.5ms. What kind of delay (jitter) I can expect from Windows?
Ignore the delay added by the USB interface/controller which is always the same. I am interested only in the delay caused by multitasking switching.
