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.
