The PID function, for correct operation, must be called at the most

regular intervals possible, thus by timer, or for more brief and

precise times, by an internal interrupt.

The function

SetOutPID

is used for the regulation anticipated by

the double function automatic/manual. It serves to avoid oscillation

of size control in switching from manual mode to automatic by the

PID algorithm.
