Hello
I try to make software in labview 7.0 with 4 USB 6008 which run simultaneously.
In my software for each card i read 3 logical inputs each 100ms and read continusly 1 analog input by bloc of 9 points at 10Hz.
This process run in parallele for the 4 cards.
That's run ok when i used only 3 cards, but when i try with four the soft really slowly and i lost lots of read.
Normaly the labview soft is multi threads and ni daqmx too, but somewhere i read that the acces to CIN and Dll are not multi treads
and the read action in daqmx 7.5 call CIN code. Like i try to call this CIN simultaneously with few acces for few cards, that perhapse slow down
my software.
My question is how can i slove this problem, how can i read quickly few inputs in few USB cards simultaneously.
regards
Eric
