I was trying to detect iButtons when touched to the 1-Wire bus and than to
read values from it using Python on Linux (Ubuntu) few days ago.
I have made some experiments with owPython and with pyowfs (
http://priesch.co.at/pyowfs) as well
Finally I gave it up and ended with the owfs daemon (running it is easy as:
/opt/owfs/bin/owfs -d /dev/ttyS2 -m /usr/local/tridicka/1wire)
I am scanning the 1-Wire directory this way:
owDirName = "/usr/local/tridicka/1wire"
for f in os.listdir(owDirName):
if f.startswith("01."):
# "DS2401" iButton ROM; family code = 01h
owFileName = dirName + f + "/r_address"
owFile = open(owFileName, 'r')
r_address = owFile.read()
owFile.close()
self.iButtonNumber = r_address
time.sleep(0.1)
it is good to set the content of the files rc.local and fuse.conf
rc.local:
/opt/owfs/bin/owfs -d /dev/ttyS2 -m /usr/local/tridicka/1wire --allow_other
fuse.conf:
user_allow_other
With the DS9097 passive
adapter<http://owfs.org/index.php?page=com-ds9097-passive>It takes 5s
max. to detect a new iButton on the bus.
