i, I'm new to the list but have been running OWFS, server, perl, php for
a few months now on my desktop with Ubuntu 7.10. Recently I purchased a
laptop to develop an irrigation and appliance controller for my
hydroponic growing business. The laptop has no RS232 port so I bought
an express
In general, the USB/serial conversion should work transparently.
Obviously your would specify -d /dev/ttyUSB0 on the command line --
assuming
that is the assignment linux is making (dmesg should confirm this).
I suppose some USB/serial adapters might not be as faithful. The DS9097U
does
need to
I do use -d /dev/ttyUSB0 and yes there is a DS2502, but this is 1kb
Add-Only Memory. The RS232 port works for other devices, just not
1wire. When I mount with OWFS and runlevel 9 it gets stuck like it's
waiting for a response and only ctl-c unsticks it. I will check on the
DS9097 voltage
Here's where the DS2502 is:
DS9097U-009 DB-9, with DS2502 ID Chip.
DS9097 needs +5V minimum to operate, I need to verify that the serial
port supplies this. I think the 1.5V is just to operate the circuits,
it should pass the +5V if it is to specs as the documentation states.

2. I only have one sensor (DS18s20). I tryed to read temperature and
temphigh. The same thing is happening. After error, I can't see the 10.*
device, not even 81.* device. Here is a ls -l /mnt/1-wire:
