If this is about a feedback control system, I'm not sure that makes sense or works at all. A simple PID controller is easy enough to parametrize, but you are indicating that they may want to experiment with something a bit more elaborate, possibly with nonlinear portions and characteristics that depend on the history. How would that work with lookup tables? Gerhard -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
