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
Note to self.
As my owcapi use of OW_init() connects to owserver, it makes sense that
all I see is /bus.0. It is for the tcp connection:
#cat /mnt/1-wire/bus.0/interface/settings/name -> tcp
Once I look in /bus.0, I see:
1F.5A1D02000000 3A.953300000000 bus.0 interface statistics
system 1F.F79002000000 3A.F59800000000 bus.1 settings structure
uncached
cat /mnt/1-wire/bus.0/bus.0/interface/settings/name -> DS9097U
cat /mnt/1-wire/bus.0/bus.0/interface/settings/address -> /dev/ttyUSB0
cat /mnt/1-wire/bus.0/bus.1/interface/settings/address -> /dev/ttyUSB1
So perhaps just a matter of discovering how things are laid out.
