poll time

Right now it takes about 6 seconds to poll my 1-wire net.

I want to add some switch inputs and would like to know much sooner than 6 seconds. My understanding is reading temperature takes a while.

How long does it take to poll 1-wire addressable switches or a ds2450?

Darryl,

What software are you using and how many sensors are you polling?

The DS18S20 temp sensor is the slowest at 750ms. Most of the rest of the chips are pretty quick (much less than the DS18S20).

ericvic,

I'm using owfs and I currently am polling 2 ds18s20's and 1 humidity on your temp/humidity board.

Darryl,

I just saw where Paul changed the OWFS code to fix some delay in polling. Maybe that has something to do with your problem.

For 2 temps and a humidity it should only take a bit over 2 seconds by the spec.
