Re: Ibutton Protection Circuit (OneWire)
Hi, Andy
may be it's a good idea ...
as iButton devices are generally hand held by everyone ( understand people ignoring what is ESD ! ), the diodes inside the Pic may be somewhat weak ...
so, a couple of fast diodes and a small series resistor are to consider.
don't forget to read Maxim AN244 ... http://www.maximintegrated.com/app-n...dex.mvp/id/244

Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!
