Re: PIC House Alarm

I posted this about a half hour ago, but it never showed up on supernews.
:-? Sorry if you see it twice, but I typed a bunch and don't want it to go
to waste. ;-)

want to replace this with PIC alarm system, has anyone done such a
design ?

Of course people have, but I haven't.......yet. It shouldn't be all
that hard to do, the largest amount of work will be in the user interface
software, the actual alarm system is simple. If I were doing it for my
home, I would make the user interface in something like VB and then use the
VB app to shove a config table of some sort into the PIC via a serial
interface. That would greatly simplify the PIC code.

I need about 8 Zones with 2 entry points a horn, 2 keypads and a panic
button , also a output for a radio controlled transmitter.

This is all easy enough for a microcontroller, for someone that has
programming experience. It might be kinda tough as a starter project for a
PIC newbie though.

this will form part of a home automation project at the end so any
ideas on a control bus will help as well ? Is X10 a good idea ?

X-10 is never a "good idea". Unfortunately it's probably the most
common power-line communication system. It is plagued by many strange and
interesting problems, mostly fixable, some allot easier than others. What
do you plan to automate?
