Hi,
With a sleep in the loop, this is what I think most people do. There is
an engineering compromise that balances the speed of discovery, the
number of devices and the bus and processing capacity.
How quickly do you need to find the new iButton?

In the worst possible way: while (true) { }
Inside the loop I start looking at present objects, dropping known
objects. Remaining items are compared with well-known authorized
codes. Other items remaining are "aliens": I log them, and after a lot
of them (in a defined time elapse) I consider it as a tampering try,
so it's an alarm.
From the bus point of view, I have an owserver active, so that more
modules can interact with it independently.
I didn't found a better way: I know that iButton does not send a
"presence" signal when connected.
Let me know what do you think about

Hi.
I'm working on the same solution DS2413P+. Also I'm planning to
use ibutton.
So I'd like to ask how did you solved: "and there is a continuous
polling
for detecting the presence of an iButton."
Thx.
