hal: lpt spindle quad encoder with pid

The basic was generated by stepconf wizard.
The rest was copied from other hal-files and self coded.

So here some improvement of this draft system.
I use it to test my closed loop spindel configuration.
The hal file and all other config is inside the attaches zip.

Thank you for posting this! I have been trying to incorporate this into my machine, and I was wondering if you could walk me through the operation of your PID algorithm.

I am having problems tuning the speed values and my displayed spindle values jump all over the place, even when I have I and D off. are there other I and D values that need to be turned off to be in true proportional mode? I am talking like 500 - 10,000 jumps when set to 200 RPM.

I know that it has been years since you posted this, but any help that you could provide would be greatly appreciated.

Edit: disregard the jumping around issue, I forgot that I changed the low pass filter value to 1 when I was testing. I have it settled back down pretty well now.

Apology for my simple question 

Spindel ein
and
Spindel links

equivalent English

Spindle on
and
Spindle CCW

then on the parport input pins

spindelencoder kanal A
and spindelencoder index
are
spindle phase A
and 
spindle index

Is my understanding correct?

Best regards

Philip

This is correct.
