Because Windows needs to occasionally use the CPU in your computer to redraw the screen, process the mouse, and perform other tasks, you generally cannot read inputs or control outputs faster than 100hz using the computer as the timer. Of course with the new multicore CPU's, you may be able to tweak extra speed out DAQFactory's polling loops, essentially putting the acquisition on one core, and letting Windows use the other core for display. This section describes how to do software (i.e. DAQFactory) polled reading and writing of analog and digital inputs and outputs. The techniques are essentially the same for both analog and digital inputs and outputs.
