How much memory is left on the RT7030 board

[jpboucha]

I would like to know how much memory is left on the RT7030 board for the VI to run and store data from a buffered acquisition. I need to acquire about a million points (16 bits each) and then transfer them to the host PC.

Attached is a VI I use to test how big a vector can be created in the onboard memory before the RT board frezes.

Hi,

To check this and other specs for the 7030devices I recommend checking the device's manual.
See page A-1 on the RT Series DAQ Device User Manual (there is 8 MB user-programmable DRAM for your program and data)
This is the link to the manual:

Also a good document that you might check for memory managemente is "Labview RT memory management", check that the best thing to do is preallocate memory before using it. To preallocate just create a dummy array of the desired size:
