Consistent robot flicker every 64 seconds

[Greg McKaskle]

Does the 64 seconds hiccup go away when disabled, if you stay in auto for 64 seconds, or in teleOp. If not, then what of your code is running in all of those cases? Start disabling things a chunk at a time. Use your intuition as to what is more likely to be responsible, but if you have no guess, just use binary search approach. Carefully take half your subsystems out of the system. Did the problem belong to the ones that remain or the ones you took out. Iterate on the right half until you identify it.

Do this in an experimental branch of your code, don't submit things or lose work doing this, but this type of debugging exposition is a very valuable skill in all forms of engineering.

Even if the issue is in WPILib, it may well be due to how your team is using it, and this narrowing of the root cause will be helpful to the people who will debug it. But there is a good chance that you will discover the bug yourself if you take this approach.
