Add new inputs in array

[NapDynamite]

Hi,

I have a pressure sensor hooked up with sbRIO and I need to save the last three measurements in an array. In the following design I am only adding new inputs when they change. Every iteration updates new values from analog inputs of FPGA and I need to save last three elements in an array of fixed size. 

 

I'll probably use this floor as a subVI later to extract elements of choice in some main VI. After calling this SubVI and wiring an input (random number gen for instance), nothing happens. I am doing something terribly wrong here please assist. 

Regards.

Another try. Seems to work.

Hi Nap,

The solution to the bottom is the same as yours, but looks better without crossing wires…
