parallel loops

[jeff_scharpf]

I will attach a picture of my parallel while loops. This is on a cRIO and so I need to reference the FPGA from both loops.

When I run it, the first loop excecutes once then the second loop goes but it never comes back to the first loop.

I am thinking that something with the FPGA reference is holding things up? I just want both loops to excecute independantly.

Attached is a picture. I have the VI if anyone wants to see it further.

I would suggest running your VI with Highlight Execution turned on to see exactly where it holds up.  You could also try putting a Disable Diagram around your second loop to see whether or not your first loop runs continuously when it is by itself.  Please post your findings, thanks!

Thanks for the response.

I solved my problem by removing the FPGA reference from one of the loops. Not sure why this works.

Before I did this, the first loop would excetute once, then the second loop would excecute, never returning control to the first.

So now I have one loop that reads buttons and updates the screen, and the other loop accesses the FPGA. 

This seems to work but I'm not sure why lol.
