Set up acquisition at regular interval on ATI-MIO-16E-4

[BenBeauchamp]

I use labview 6.01 with an ATI-MIO-16E-4 and a scxi 1100 to aquire temperature readings. When I use AI aquire waveforms I can set the time at which I get data in a while loop at let say every second or every two seconds. When I use Ai Config, AI Start and after AI read in a while loop, I don't have control on the read time interval. I can I control that time?

Are you wanting to set the hardware time interval (actual time between hardware scans) or the time interval between when you are actually returning the data to LabVIEW (time between AI Read VIs within while loop)? Either way, you will be able control these times within your program.

For changing the hardware time interval
--The AI Start VI has a scan rate input. If you are wanting to decrease the rate the hardware is acquiring data you can decrease the scan rate.

For changing the time between AI Read VIs in while loop
--You can implement a LabVIEW wait function within the while loop. This will create a delay and increase the time between calls of the AI Read VIs within the loop. There are two wait functions you could use: Wait (ms) or Wait Until Next ms Mu
ltiple. Both functions are within the Time and Dialog supalette.

I hope this helps.
