Martin:

There are two ways I'd recommend going.  Ok... Maybe three.  I'll list
them in order of my preference, from least-desirable to most:

    1.  Find the right books, read them, then write your own code from
        the ground up.  Yuck.

    2.  Get a copy of the Microchip-endorsed "fuzzyTECH-MP" fuzzy-logic
        development system from Inform.  It runs under Windows, the
        interface is easy to use, and you can start writing
        fuzzy-control apps nearly immediately.  The version I have
        (version 3) doesn't explicitly support all the newer 16Cxx
        parts, but it generates code for all three PIC families, so you
        can probably MAKE it work on any specific PIC.  Version 4
        (which I haven't seen yet) will probably support all the PICs
        explicitly.

    3.  This one's pretty expensive...  Buy the "MP-C" C compiler from
        Byte Craft Limited, and while you're at it, buy their "Fuzz-C"
        development system.  The interface isn't as pretty as Inform's,
        but Fuzz-C gives you a lot more flexibility.  Since it outputs
        C code, you can use it to write fuzzy systems for any
        microcontroller, microprocessor, desktop PC. or
        massively-parallel supercomputer... Doesn't matter.

    FuzzyTECH-MP is really written for control applications.  This is
    ok, but control problems can often be better solved using
    "traditional" techniques.  If you really want to explore the
    capabilities of fuzzy-logic as something other than a
    pendulum-balancer or thermostat, get Fuzz-C.
