Hi folks,
I'm currently designing an open-hardware 32 port 1wire bus master for part
of my home automation system, and would like your input.
The design is based around an STM32F412ZG microcontroller, with MOSFET
active pullups & drive transistors. It will present as a hat for the Orange
Pi Prime

owlib does have support for that kind of device -- (multiple buses) -- The
DS2482-800 is a good example. It has one "port" and multiple buses. The
port gets locked for just the message (e.g. serial communication) and the
individual 1-wire bus and slave gets locked for the 1-wire "conversation".

So I gave it another try today, by trying to address it from an arduino uno.
Again the "old" issue of contrast (no pixels/dots visible). Looking at the
example code (PHP) does not help too much as I do not understand how to
manipulate single pins e.g.
(I did not check with owfs today as there i
Hello all!
Thanks for the numerous replies and suggestions to this topic! To make a long
story short; I decided to not insist in a free/open solution for now and
ordered a ethernet2wifi converter as I have an unused ethernet master around.
For later I consider using a Raspi Zero W + level-shift
Hello all
Its about 1 year since I played with Arduino 1wire slaves last. I have the
impression a lot has happened on that field since (moat, etc.). Where should I
start?
I would tend to go for moat onewirehub (instead of owslave), does that make
sense? Is it supported by owfs as moat device o

The Arduino Yun has an ARM processor, too. It's called "Wifi shield",
but it's the main processor of that board. The AVR is on-board to be
able to call it "Arduino",
The one thing I see missing is if you run it on a PIE and send it to another
device over wifi then you eliminate any chance of thunder crashing a whole
system and I mean everything in your home! Of course I live on the beach and
we do have lot of storms! I just remember when I had a bolt land
I reiterate that I think this is shoving a round peg into a square hole.
You requirements scream to me that you should be using an RF node that
beams your data into a gateway Pi behind closed doors and attached to the
wall. Low power + existing libraries for 1Wire. This RF unit (I use
Moteinos) wou
If for some reason the leg that a DS2450 is on drops off line and then
comes back online, the values that are retrieved don't make any sense.
If I restart my program it will work again. Is there anyway to
reset/reinitialize the DS2450? I'm reading the values from it with a
