You mean "trit," not "bit," and the usual word is "ternary."

    Here's your generator:

    for (int i = 0;  i < 43046721;  ++i) {
       ... do whatever you want with `i' ...
    }

NOTE: This is for educational purposes only.  If you use my
sophisticated ternary generator in a commercial product or
in furtherance of any commercial venture, you must first
negotiate a license with me.  It's not expensive, though,
since I charge on a sliding scale: just one cent for the
first ternary number, three for the next, nine for the third,
and so on.
