This is an ambitious, but tricky change. When you are happy with it, let me
test it too. I can construct a 2 level network here.
My idea is to transfer the BUS_select_branch() from BUS_next into BUS_select.
This should do no harm --

There are some subtilties with deeper branching. OWFS kee[s trak of the
last selected path to reduce redundant path selection (you have to turn off
all sister DS2409s at each level). I'll add a flag that marks the stored
path as

Hello Roberto,
Very nice work.
I found the documentation at the end of the file (as you had said) and have
a few comments:
A. I dont believe there is a default port for owserver.
Should we issue a request for a registered port

Sounds fine. We also have an mdns protocol registered.
Do you want to submit the request?
If you are ok with it, I will. It may take some time until I collected the
neccessary information for the application (protocol details etc),

any idea on what port should we use as default today?!
As IANA will choose the port number alone, just waiting for the application
result seems to be a wise idea -- I expect it to be through first week after
new year's eve. In the

Can owfs/1wire read in mili-seconds?
That might be pushing it.10 to 100 msec.
That would do, 10.000rpm ~ 180 pulses per second, but if I take a pulse
from the cams it wil be 90

Great news, 4304 is out default port. I'll modify the programs and examples
to use it. In general, if no port is specified, 4304 will be assumed.
That's indeed great news. owserver has a default port now and will be put

Dear All,
Does anyone have experience of working i2c interfaces for either
DS2482-100 , DS2482-800, initially something parallel port based would
be ideal.
I posted a schematic a while ago. To avoid cluttering the list, I mailed it

Do I need to power the 18B20 with Vcc for this distance?
No. Power requirement of the DS18B20 is max. 1.5mA, which causes only a
voltage drop in the mV range even on long and thin 1W and GND lines.
Check for contact problems at the

If you power a lot of onewire chips (and peripheals) over a thin, long
cable, the GND niveau at the end of the cable may reach 0.7V due to the
current through it. This disturbs the onewire function for chips at the
end of the cable a lot.

not exactly a Software Question but anyway. I intend to switch mains

Solid state relays, e.g. by OptoZZ or similar behave as a LED on low voltage
