PID library is blocking when the setpoint is reached

[Lorenzo]

Hi everybody,

I am trying to control the speed of a DC motor with Teency 3.5 by reading data from the encoder.
Everything seems working but, when the motor reaches the setpoint speed the PID.Compute function is blocking and the motor stops moving.

My question is: which should be the output of the myPID.Compute(); function when the setpoint speed is reached?

Thank you.

Are you using this library ? https://github.com/br3ttb/Arduino-PID-Library
it doesn't look like compute() has any "blocking" paths.

methods/functions are described at https://playground.arduino.cc/Code/PIDLibrary

Thank you very much Manitou, so maybe the problem is not due to the PID function...
