Hi,
my previous post was sent incomplete by accident, sorry.
I would like to know what is the recommended way to periodically search the
1-Wire bus for the presence of new devices?
I mean iButtons, for example, are connected to the bus randomly (on
occasion).
If I do:
from pyowfs import Connection
oneWireAdapter = "/dev/ttyS2"
ROM = "DS2401" # iButton ROM
while 1:
root = Connection(oneWireAdapter)
s = root.find(type=ROM)[0]
print s
time.sleep(0.1)
I am getting following message after while:
DEFAULT: ow_com.c:COM_open(43) [Too many open files] Cannot open port:
/dev/ttyS2 Permissions problem?
Is there a way, how to close Connection? I was searching the source code,
but no luck.
Petr
