PID-filter routine (2nd try).

[RodSTAR]

Dear sir,
I check INCPID routine it works fine as position control.
I want to control speed via PWM what should i change in the INCPID routine
and also how can i give pid_Kp pid_Ki pid_Kd using external potantiometer
which is reading through ADC CH which gives 0-1023 value and how i convert
this value to $0xxx figure.

As I understand, this PID checks only position.
To control speed, you should use another routine to control position AMONG TIME (speed), using this PID routine as position control. I did that and works fine. Not just simple speed but parametrical trapezoidal (lineal, curve, log, exp) starts and ends, via USB to my laptop. It works fine almost like an industrial servomotor (24V 500W DC motors). My next experiment is to implement it with 4 BLDC motors I have. I'm in the way to control with a iPhone. Henrik doesn't know how gratefull I am to him for his seed piece.
