Re: Thread scheduler for PID period control ?

I'd like the OP or any others that have done PID loop timing changes to share what inputs/outputs they are using. What do these custom PID loops do on the robot (drive, interact with game/field items)? I am curious as to what needs a custom timing rate, as I haven't done anything myself that needed this for a PID controller. What was the behavior that led you to believe you needed a faster timing rate? If you post your code repositories publicly, please share the URL so I can try to follow along with what you did. One of the posts mention a change of "PID values" (I assume the coefficients), why did you do this? Thanks!
