Hi,

I4m trying to implement a PID algorithm in a 16C711 PIC.

I found different kind of informations in the internet. Something which
is
not realy clear to me is the difference between the "velocity" and the
"positional"
PID approach.

The thing I like to do is:

Controlling a PWM dependent to a measured voltage if the measured
voltage
ist to low  the pwm should be increased and vice versa.

Does eventually somebody has some code to share ?

Kind regards

        Stefan
