Parallel DAQ and Post-Processing of Data from DAQ

Thanks nlquist. I've made the changes you suggested. Definitely better than the way I did it earlier.

For some reason, after the first acquisition, I always get an empty array. I've attached the main VI, configure DAQmx, and Read DAQmx as JPG. I'll attach the Close DAQmx in the next post since I can't do more than 3 attachment in a single post.

I only had time for a quick look but I think you will need to change from finite to continuous samples in your config VI.  It may also be that the sample to read input (shift register) in the main loop somehow gets set to zero after one iteration.  You can probe it to be sure.

Bingo ! That worked. I was able to knock a few seconds from the cycle time too ... thanks !
