LabView Timming Resolution question

[Magela Moore]

I am in the process of creating time-criticle software using LabView.
I've been told that LabView can't handle timing resolutions
less than 1 ms. ( ie, if I need to transmit something at a .75 ms rate)
LabView can't do this. Does anyone know of a patch I can obtain
to get around this resolution threshold?

Thanks,

Magela

I believe there are 2 seperate issues here. The 1ms resolution is not from
Labview
but is a function of the PC and OS. For highly time critical operations your
best bet
is to get away from Windows and move to a RTOS (real time Operating System)
There is a labview package (I believe) that supports this.

As far as transmitting at a .75 ms rate that is completely different. It
depends on the
hardware you are
using and whether or not you need absolute control over
each
bit that is being transmitted.

For example .75 ms is only 1333 Hz which is easily obtainable with most
harware.
If you can buffer up 2500 bits (assuming one bit per cycle) then you should
be able
to stay ahead of the transmitter.

Hope this makes some sense.
