LabVIEW
synchronizing data streaming out of hardware aquiring data at 2 different rates.
I have an application in which I am aquiring data from 2 peices of
hardware, an Emant300 USB daq device and a Mitutoyo Linear
Transducer. Due to limitations in the hardware, the slowest that
I can run the Emant is 10 HZ or 10 samples/sec and the fastest I can
run the Mitutoyo gage is 4 hz or 4 samples/sec. Both are
outputting a double number every cycle. I want to be able to
"synchronize" the data between them.
I was thinking that maybe I could take every third data point from the Emant by using a while loop, shift registers, build array and an index array, (see VI below) but I ran into some issues with that (I am not sure how many data points I will have, as we will be aquiring data for 20-40 seconds, so 200-400 data points.) I was having trouble implementing this in real time as I am displaying the data in real time via refernces to my main VI (each of the hardware is controlled by a subvi running in parallel.)
I am not sure if Queues would work or not.
Didnt know if anyone had a hint or another idea which might work.
