PID library's including autotune

[dave]

In my surfing around on the internets last night I stumbled across some very useful bits and pieces.

PID library for Arduino: http://playground.arduino.cc/Code/PIDLibrary

Very detailed description here: http://brettbeauregard.com/blog/2011...-introduction/

Lastly PID autotune library for Arduino: http://playground.arduino.cc/Code/PIDAutotuneLibrary

Hi Dave, as I commented in my email today, the arduino PID library is so so, I made some good improvements which I will dig up and send to you once I fire up a laptop I have not used for a year or so.

There is a GUI to connect and tune this library also written in Processing, that again is full of bugs. I'll see if I still have my hacked/improved version and send it to you.

The auto tune library looks interesting although I have not used it or seen it before.

I also have a PID routine I wrote a while back in GCC to suit the German beer keg board posted here over a year ago.
