Reading a pulse tran from PS/2 mouse data wire and using the as a 2D tracking device.

Windows 95
Pentium 166
LabView version 5.0
DAQ card ATMIO-16
Signal Digital input

A mechanical engineering student at University of Texas at Arlington, trying to develop a 2D tracking device using a simple mouse. I have looked various mice connections (USB, PS/2, etc) and decided to test signal on a PS/2 data line.
I am running the ground wire and data line to my DAQ digital inputs on the card. I have successfully used on of the digital I/O example vi in LabView to read in an 8-bit binary pattern.
Now the data is coming in very fast. How am I able to read this pulse train of bits and decode the signal of bits if they are coming in so fast? Is there
a buffer in LabView, which allows me to read from, and so it gives me enough time to decode the bits so I can extract the x and y coordinates and then send them to my graphing chart, in order to keep track of the mouse.
I already know the bit encoding method so I need is how to get enough time to decode. Each pulse width is 50 microseconds
Are there any limitations to LabView in this area of data acquisitioning?

UTA,

Unfortunately the Digital I/O on the AT-MIO-16 are not hardware timed (software timing only) and therefore do not support buffered Digital I/O. You could use a PCI-6533 for this purpose.

With the AT-MIO-16 the only suggestion I can offer is to use a build array function to Concatenate each reading from the Digital I/O ports together. Then you can process it at a later time or in an different loop independently.
The rate at which you read the digital Port/Line is going to be software dependent.
