Microchip actually has a fuzzy logic developement system - they call it fuzzyTECH - MP. We have it, but nobody here has used it, and I don't know anything about fuzzy control systems, so I can't comment on it's potential usefulness. The manual is copyrighted 1994, so it has been around a while. I scanned the introduction and was quite amused to see the terms "fuzzification" and "defuzzification". -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
