Hi, Martin,

I am looking a good origin for PID C source code.
Are you SURE you really want a PID controller? There are many other control technologies (bang-bang, SPC, etc.) -- each has characteristics suitd to different types of control problems.
And, even if you *think* you want a PID controller, are you sure ou need all three terms (i.e. P and PI controllers are far more commonplace).
You'll also need to learn the basics about PID controllers if you ever expect to deploy anything non-trivial. I.e., tuning can be a real chore. And, there are many ways the controller can "fail" (to perform adequately) if not designed well (e.g., bumpless transfer, anti-windup, etc.)
Do yourself -- and your project -- a favor and research control theory before trying to *apply* that theory... :-/
HTH, --don
It would be nice if it also includes software which will help tuning the PID loop. I may also consider self tuning algorithm.
I consider to include it in our RTU (remote terminal unit)
.
