Thank you all for the help.
I compiled using the version of daemon() supplied in ow_daemon.c, and that
did the trick!

Hi,
from owhttpd, select eeprom/page.0, upload the generated file and save
change.
You may need to erase the page if it already content some data.
You may also copy your generated file rob.bin to eeprom/page.0 (via fuse
file system) from the shell or within the makefile.

Mmmh, actually the humidity sensor seems to have died.

Hello,
We are pretty close to a usable sdl frontend for owfs but I keep running
into some timing problems.
We read the sensors from the owfs mountpoint (not owcapi because this
way it is also possible to read from proc or sys) but due to the amount
of sensors the total reading time is a problem.
hi
I've managed to build a simple,limited debian (lenny, 5.x) package from
owfs.
configure options used for this package:
--enable-debian --disable-owperl --disable-owtcl \
--disable-swig --disable-owphp
you can get it here:
amd64: http://chaschperli.ch/debian/lenny/owfs_2.7.31-1_amd64.deb
This is my thought, yes. I was thinking something along the lines of
read an int at addres and call it temperature type commands.

I've been adding a new device to my 1-wire network that I regularly poll (a
solar sensor + temp from hobby-boards). Since then (I think!), owserver
seems to stop responding after a while. Sometimes it takes 6-10h before it
hangs and sometimes just a couple of minutes.

Jim,
I like your idea.
I think your example needs to be more like:
create the filename temperature
read a 16 bit int at address x
push it through transform table q that outputs a float
output the float with the printf string %s.
This assumes that the transform is done on the OWFS side rather
Thank goodness the problem was a bad sensor. I ran a test also with no
problems:
p...@amd64$ for x in 1 2 3 4 5 6 7 8 9 ; do /opt/owfs/bin/owread
/uncached/26.3D3A1500/humidity ; sleep 1 ; done
27.505 27.505 27.8532 27.505 27.505 27.8532
27.505 27.505
C++ ?
Is all the reading in one big loop? Then how fast is your loop actually
cycling? The filesystem does an actual call to libow and so may block while
the temperature conversion is progressing if the cached value is old.

There are 3 ways to use python and OWFS.
1. run the FUSE virtual filesystem (program owfs) and just do standard read
and writes.
2. run owpython, which is a standalone program and embeds all of owlib. see
http://owfs.cvs.sourceforge.net/viewvc/owfs/owfs/module/swig/python/examples/
3. run
To answer a very small part of your question: No problem. The owserver that
actually connects to the slave in question will be the one that holds its
configuration.
It seems like you almost want a small transform language embedded in OWFS.
Does this already exist? It would be nice to use an

Hi PAul,
1) In normal operation does the contents of the uploaded file appear in the
text window ? and then you press [change]. Knowing this would help me in
fault finding.
2) Can the bin file you upload be on the client machine (win XP) ?
3) Pascal stated the AE file goes into the EEPROM

Well, not really. My problems (serial not working) are still there, the fact
that this sensor's AD convertor apparently just died is separate.
Paul,
I wasn't so much thinking about what was right but looking at
generalizing what OWFS does today.
How do you convert from the data reading on a 18B20 to a temperature?
Same goes for a humidity level or a thermocouple reading.
It seems like you have readings you get back, and by knowing
