What you do here is that you initiate a simultaneous read, and force two
simple reads after as well. You should initiate the simultaneous read, wait
1-2 seconds, and read the cached values.

As I know there are other chips (battery monitor, I can't recall its name)
what can be used for AD conversion on 1wire bus - but I never tried these

Thank you -
I have the latest RasPi which came out with 256MB RAM (I think it is called
Rev2 - with mounting holes on it, altered GPIO, and made in UK). does this
has polyfuses removed from USB?
I checked voltage between TP1 and TP2 - it says 4.84V
So what I'll try:
1. upgrade kernel (now its ru
disconnect for example) stopped USB working, but after I disabled
the daemon (I cant recall its name, its reposnsible to alter networking
based on connect-disconnect events), it was resolved.
So now I have problem only on reboots.

In the same time I'm able to see the files what w1 mounts (/sys/bus/w1/devices)
and read values without problem (But I have to say, one time it was frozen
using this method as well)
I upgraded kernel, packages, but no help.
What can be wrong?

I asked Hobbyboards about the availability of this LCD controller, as I
could not find it on their website.
"Attila,
Unfortunately at this time we no longer offer our LCD Driver device. We may
have one available in the future but I do not have a time frame.

The PIC driven LCD controller is caching button states until its read out -
at least it is written in the specifications. Although I have no idea how
it works in practice...

ience how can I read these status changes out, how does this event
counter work in practice?
Thank you,

Nice. I'll be more careful next time with too cheap products...

dd a new sensor to this "node", I just insert these wires to the

sensors to one node with this.
However, I'm not completely satisfied with this solution. I'd like to avoid

If we are talking about cables - how you use UTP cable? Let me explain

In my current installation I use a twisted pair for GND and Data, and use a

No, it is not an UTP cable. UTP=Unshielded Twisted Pair.

This is NOT a CAT5e UTP cable.

Hi All,
I'm new with OWFS and Python as well, and working on a project to read some
temperature sensors. I found OWPython module very handy, and easy to use -
although now I hit a problem, and Google did not provide an answer for me...
I use a DS2450 AD converter to read an RTD sensor using the a
