1. Starting owfs with
/opt/owfs/bin/owfs -F -u --mountpoint /mnt/onewire --error_level 4
would work.
2. So would 2.5p1 (just released)
3. DS1921G thermocron) support might be a little flaky. I clearly need to work on it. Basically there are so many features in the DS1921 that it's quite a chore representing it as a filesystem.
My thought is no make rollover, timestamping and histograms transparent. My hope is to make it possible to pipe the output from the DS1921 to gplot to get nice displays. Tell me what you want to do with it.

Hi,
I'm having trouble seeing the files/filesystem in my DS1921G using owfs. I can
view data through owhttpd but that's not sufficient, since I need to be able
to access them through owfs, in order to use temploggerd. Iwondered if
anyone might be able to point out where I'm going wrong please.
System: Mandriva Linux (Kernel 2.6.12.25), USB connector is DS9490R, Sensor is
the DS1921G (temperature datalogger)
I've configured (confiuration is shown at end of e-mail), made & installed
owfs-2.5p0 without any apparent hitches. Then, I've opened a shell, su'd to
root and done the following.
[EMAIL PROTECTED] andrew] rmmod ds9490r
[EMAIL PROTECTED] andrew] /opt/owfs/bin/owfs -F -u /mnt/onewire --error_level 4
In response, at the shell prompt, I get 1000's of lines saying . . .
DEFAULT: Not a "character" device /mnt/onewire
DEFAULT: Not a "character" device /mnt/onewire
DEFAULT: Not a "character" device /mnt/onewire
etc.
etc.
A quick check of which processes are running, shows that owfs is indeed
running.
'DEFAULT: Not ..... etc' continues to print out indefinitely, and the only way
to stop it is to identify the PID of owfs and then kill it in a shell.
If, before killing owfs (as mentioned above), I open another shell and do
'su' root, then 'cd /mnt/onewire', then type 'ls' to view the files under
that directory, I get nothing visible within that directory. ie. The cursor
simply moves to a new line '[EMAIL PROTECTED] onewire]'.
If I open a konquoror window (as root user) and attempt to view the contents
of /mnt/onewire, no files are visible in that directory.
It seems that I must be doing something wrong, somewhere. Or am I ?
I would really appreciate any useful feedback on this problem.
Cheers,
Andrew
