4) Have you tried searching the forums and reading some of the many threads on this topic?


1)I have yet to successfully regulate any robot functions using the built in LabVIEW PID tools

2) I used the PID.vi in the default toolkit

3) PID is the only method that I have interacted with, but I am open to other methods.

4) Yes, I have. Quite extensively, actually. Otherwise I wouldn't have started a thread. I needed an example of implementation of PID in robot code through the DIO; It is not the theory behind it that is posing an issue. I am capable of using Google, but a search engine is only germane if the query is capable of finding the resource needed. If appropriate resources cannot be found in existing resources, then posing a thread in an attempt to better understand an issue is pertinent. As such, given the lack of specific examples that I found on the forums, I decided it would be best to attempt to find the answers by means of a new thread.
