There is an excellent article called 'Driving Triacs with the PIC
micro-controller' written by Bart Trepak in the March 1996 issue of
Electronics Today International magizine (UK) pgs 38-46.

It covers what you are interesting in, along with some flow charts,
assembler code & cct diagrams for swiching & dimmer control via the
PIC 16Cxx to get you on your way.

If you have trouble locating this article email me and i'll send you a
copy by post. Recently sent a copy to an American guy who was
interested in the same thing.
