Hi Mark,
oh yes, it is....
I have 4 DS2482-100 bus-master connected via I2C and several 1-Wire
devices connected to each. So OWFS shows me all devices together,
independent of the bus-master in the root /. and in addition it shows
bus.0 to bus.3.
And - I guess that is what you want - if I dive into bus.0 it shows
the devices again, but now limited to that one only connected to bus.0.
So you can ignore the devices shown in the root and go through the
bus.x directories showing their content, than you are able to show
where they are connected...
Achim,
I am getting different results, depending on what I use to read the root
of the owfs.
I *do not *see all the devices which exist beyond the first DS2408 in
the root of the mounted owfs directory through my program or an ls
/mnt/1-wire. I also only see bus.0. However, when I use the owfs
utility owget, I see the two buses.
My physical network looks like this:
USB /dev/ttyUSB0 -> USB TO SERIAL ADAPTER -> [DS2480B] ->
[DS2413 (0x3A)]
USB /dev/ttyUSB0 -> USB TO SERIAL ADAPTER -> [DS2480B] ->
[DS2409 (0x1F)] ->{main} -> {sensors}
USB /dev/ttyUSB0 -> USB TO SERIAL ADAPTER -> [DS2480B] ->
[DS2409 (0x1F)] ->{aux} -> {sensors}
USB /dev/ttyUSB1 -> USB TO SERIAL ADAPTER -> [DS2480B] ->
[DS2413 (0x3A)]
USB /dev/ttyUSB1 -> USB TO SERIAL ADAPTER -> [DS2480B] ->
[DS2409 (0x1F)] ->{main} -> {sensors}
USB /dev/ttyUSB1 -> USB TO SERIAL ADAPTER -> [DS2480B] ->
[DS2409 (0x1F)] ->{aux} -> {sensors}
Here's how I load owserver (and owfs):
#/usr/bin/owserver --device=/dev/ttyUSB0 /dev/ttyUSB1 -p 4304
--allow_other
#/usr/bin/owfs -slocalhost:4304 --mountpoint=/mnt/1-wire/
--allow_other
When I ls /mnt/1-wire I see:
1F.5A1D02000000 1F.F79002000000 3A.953300000000 3A.F59800000000
bus.0 settings statistics structure system uncached
And in my application:
OW_init(-s localhost:4304);
OW_get("/", &get_buffer, &get_length);
printf("\n%s\n",get_buffer);
3A.953300000000/,1F.F79002000000/,3A.F59800000000/,1F.5A1D02000000/,bus.0/,uncached/,settings/,system/,statistics/,structure/
When I run *owget* at the command line:
owget -s localhost:4304
/3A.F59800000000
/1F.5A1D02000000
/3A.953300000000
/1F.F79002000000
/bus.1
/bus.0
/uncached
/settings
/system
/statistics
/structure
I'm examining the sources for owget now, and note that the methods used
are outside the scope of owcapi. They appear to circumvent owserver and
the userspace directory structure entirely.
Here's the debug produced when I run my test program. Maybe someone can
make sense of this?
