RE: Re: Displays round the house

["Broadfoot, Kieran J" <Kieran.Broadfoot@xxxxxxx>]

Ive had many conversations with Dallas over this issue.  Their
solution is
the following:

---
Yes, you can use the DS2406 to communicate data onto the 1-Wire Net.


           ------- 
clk  -------
   1-Wire       
A-------       
----------DS2406   data  Micro 
          
      B-------      
          
-------       -------

1.  Setup the DS2406 to 'alarm' when activity is scene on data
line.
2.  Read the data coming from the Micro by clocking the data.

Given the complexity of writing your own 1-wire slave code on a pic
this
would be the easier alternative.  Ive seriously considering attempting
the
project of writing my own code but by all accounts timings will be your
enemy.  That said Id love to see freely available code to it but all
ive
ever seen has been closed source.

Hope this helps

This is presumably because the pic is emulating a one wire device?

I would like a more powerful one wire device with multiple outputs, a pic
seemed like an idea...what is the dallas suggested alternative?
