PID for Gyro oscillating all the way to setpoint
you should keep tuning your PID, trying to increase the D terms and if it's oscillated to much you should lower a little bit your P gain, and I would suggest you lower the maxOutput of the PID.

Pid working differently at different distances
Yes! That was our issue. All the documentation we were finding was telling us to do P, then add in I, and it was causing us to way overshoot. So, a with the gracious professionalism of FIRST, we...
