Communication to DS9097U not working

Hi,
we have a "test" installation with a 1-Wire Adapter USB DS9490R (eService) and connected sensors constructed as all sensors have been read correctly.
Now we have the "end installation" with 1-Wire bus coupler USB Pro, Isolated (eService) -> 1-Wire hub III DC (eService) -> i-wire bus -> sensor
On the bus coupler, we have connected a owserver but no sensor is displayed.
We have following trace:

Yes, sure - sounds perfect! Happy to test it!

(I tried to implement it myself but I am not familiar with the owfs source - don't know where to start. ;)

That would be great!

Thanks a lot!

>some advice what to do?

So from what I can see I have 2 options:
1. modify hardware: unsolder some of the DS2408 pins in order to change wiring of the LCD
2. modify software: change the owfs code to swap some bits

Recommendations?

How to use eservice LCD

Hello

I bought an eservice LCD [1] but it does not work. Can somebody give me some advice what to do?

Rookie Mistake

I bought 4 DS2483R ICs from DigiKey, two bucks each.
I thought I was getting something I could work with. Hah!

If anyone in Canada can use them I will mail them gratis.
In mid July I can mail them to anyone in the U.S.

AB Electronics

suggests using a 1-Wire DS2482-100 bridge from AB Electronics to connect to a DS18B20.

Does anyone know if this board is sold in Canada or the US?

Thanks,

New install of OWFS on RPi running Jessie

Hi Guys,

I’m giving my OWFS based heating system an update.

Currently I’m running on a RPi 2 with Wheezy 7.10 and some LinkUSB adaptors and am wanting to reinstall on
the latest releases.

I’m trying to do a clean install onto another RPi running Jessie and using the latest release doing an
'apt-get install owfs’ but it didn’t seem to want to start properly.

I then went and got the current source code and have done a build (once I git all the dependant libs etc) but
just wondering what the current recipe is to get a good stable system on an RPi?

Any suggestions?

Regards

Alex Shepherd

Wouldn't parasitic power onewire be symmetrical? Seems to work for me...  

I have probably 150 feet of CAT5 chained around my house. Sometimes out on one pair and back on another to
continue the chain. At the far end of the chain, a 1N5711 Schottky diode and a 1.5KE20A-T TVS reduced errors
a bit. What really cut my errors to zero was adding a 0.02 uF capacitor across the start of the chain. It
drastically slows the signal rise times, but doesn't seem to hurt readings. It completely stopped the
seemingly random storms of errors that would appear for a few hours and then go away for days. Military
radar? Spooks? 

But that is with an ancient dedicated microprocessor at 5V - not with owfs. It reads and sets up a different
single DS18B20 of the ten connected, every ten seconds. Often goes for months without a single missed
reading now.

Cable Length

My DS18B20 works over 34 feet of Cat5e but not over 160 feet.
Resistance for the 160 foot wire is 4.7 ohms, 0.29 ohms per foot.
Resistance for the 34 foot wire is 0.9 ohms, 0.26 ohms per foot.

Both lengths of cable are from the same 200 foot length.

Is my 160 foot cable too long or might I have another problem?
I have read that 1wire is good for 100 meters over Catx.

Thanks,
Peter

Concurrency issues?

Hello,
I use owfs since 2010. I had it running on an old pentium 133MHz PC driving 
my heating system in the previous house. I then switch to a Raspberry Pi. 
Then moved to a new house. In my new house I have 2 Raspberry Pi running 
owfs. 1 is driving the heating system + various temp, humidity, lcd. The 
second one monitors the swiming pool and drive the pump. 
Everything can be seen at my web site gcolin.hd.free.fr
So the first thing I have to say (again) is a big thank to the developers. 
Because owfs is just awesome! Making 1wire life easy ;-) Many thanks for 
this.
I am happy with my systems they are running almost perfectly.
Why almost? Because sometimes I loose devices. I have been fighting with this 
for a very long time. First it was happening on the swimming pool system last 
year, I was accusing the hardware so I replaced the 2482 i2c bus master with 
a serial one, same problem, then a hobby-board hub, same problem, then 
changing the wiring same problem. I was banging my head against the wall. It 
was happening randomely, let's say once a week. Then since 6 months without 
any change (I'm back to 2482-100 bus master) I don't loose any devices. My 
trends are perfectly logged (I log every 5 minutes).
But since a few months it has started on the other system! I lost a temp 
sensor. This system has a 2482-800 bus master (i2c -> 8 channels 1wire), I 
have separated this sensor to a bus where it is alone: same problem, changed 
its cable (because it was a pair in the same cable than another 1wire bus) 
same problem again. I decided to connect it to an arduino and have this 
arduino send the data to the pi by serial. It works fine but guess what? owfs 
is now loosing another sensor.... :-( 
Finally I decided to come here to do some reading and I see you are saying: " 
don't use the owfs-fuse interface for anything but demonstration purposes, as 
it has concurrency issues."
Is this my problem? What concurrency issues are you talking about? Every 
owfs? or when owfs is used in conjonction with the kernel 1wire module (I 
never tried it)?
My 2 systems are identical: Raspbian wheezy in full read only (I don't want 
to upgrade I want to keep it fixed when it's running no change to anything). 
Running owfs from Raspbian repo: 2.8p15.
I use owserver and owfs fuse interface daemons (no owftpd, no owhttpd), 
access all my devices thru /mnt/1wire/ did this for 6 years. Is that wrong? 
Should I use owread, owwrite, owdir, etc?
Please, if you can give me some light on this concurrency issues.
Thanks a lot.
