Instability using ANC daqmx

[Kevin_Price]

Sorry, I really can't help with the noise cancellation control algorithm, it's not a field I know about.  Now that we got latency out of the way, there's not much more I can offer.

Can you help me? My "Error Mic" gets unstable, instead x+y during the time tend to zero.

Unfortunately I also cannot help you with your ANC algorithm.

I can only suggest (again):

• Clean up your VI! This will greatly improve readabilty of your code…
• Why do you use DeleteFromArray to index an element from an array? Ever heard of a function called IndexArray? (That function also has the benefit to be able to index more than just one element with one node. And it even don't needs the index constants as it automatically starts to index elements from index 0…)

Thanks Gerd for your cooperation.

What do you mean by: "Clean up your VI"?

In the LabVIEW help you will find a chapter called "Style guide".

It recommends straight wires, going from left to right…

(That's just a start, there are other things to follow, too.)

Example:

The upper DAQmx task reference also should be kept in a shift register. You don't need shift registers for the error wires when you stop the loop on the first error…

Thank you for your cooperation but it still doesnt work 😞
