Real time PtbyPt filter

[cvb00000]

Hello,

I have a program that runs on a real time controller that takes data and processes it. Part of this processing is doing an FIR ptbypt filtering. These vis are in a  loop that runs 200 iterations and that loop runs in a 32 iteration parfor loop. Problem is, the ptbypt filters are not returning the correct values. Is this due to the ptbypt filters writing over each other in memory, or some other problem? Btw I have set up everything for re-entrant execution.

 

Thanks,

 

Brad

There are USRs in the ptbypt. That will be a problem. There's a good explanation of how to address this on pages 45-47 of this document:

A quick picture of your code or an upload of the relevant VI would help us understand what you mean.

Thanks Todd, the fix worked perfectly.
