Daqmx, queue, and memory

[jyang72211]

Hi all,

I have a loop that would read the analog in buffer and put the data (24x1000 2d array /element) onto three queues (one for display, one for file I/O, and one for motion control).  It seems to be that this is very wasteful, but I can't think of a better way.  Apparently, LV agrees with me, and it is giving me a memory error, saying that I don't have enough memory to perform the operation.  I understand that I am buring a lot of memory, but it surprised me that LV can't handle that.  Can you help?  Thanks!

Hi jyang72211,

can you upload your vi, so we can look into it?

Maybe it helps if you use an action engine for your data and only send a "new data" command with the queues.
