[time-nuts] I want a good micro-controller

   My favorite for many uses is the Freescale MC68HC908QT4, or others in
   that series. Freescale provides a complete C development environment
   for free. The QT4 is an 8-pin package, with up to 6 I/O pins. I've used
   it for everything from a 555 timer replacement to the controller for an
   RPM meter, to the controller for a GPS/Rb/xtal freqency standard. Of
   course, for many purposes it doesn't particularly matter whose chip you
   use, as long as the tools are adequate. There are any number of
   choices, including the PIC line, which everyone but me seems to love.

part with great, free C/C++ support, you'd most likely be happy with the
AtMEGA series.

Yes that's exactly my plan. No GPS and designed for field use. A halfway
decent crystal with interpolation from 1 PPS timestamps should provide
decent results. And anything else I can dream up.

Bottom line is I need to know which micro-controller to embrace.

Thanks Didier for your suggestion. Any others?
