Hello,
i build owfs (Now 2.9p8) together with collect (now 5.4.1) with an buildroot
System for my x86 (32bit)
softwarerouter (www.fli4l.de).
In that i have activate OWSERVER; OWHTTPD and OWFS.
My USB-Adapter is set for be using with OWSERVER and OWHTTPD and OWFS will be
connected
to the OWSERVER (But similar timeouts i will get without OWSERVER and OWHTTPD,
when i
connect my USB Adapter directly to the OWFS)
By the onwire-plugin i made an modification, so that this can read more
sensor-tyes as only type 10
(I use type 28, but also type 31 and else).
Now the opnewire-plugin read in the data directly over the libowfs (There is no
seperate program from
me made for that).
Please note, that i am be also only an "user" from different ready Systems (From
the main programming)
and have also only used some script for the preparemend here. But the main
collection of the data over
collectd with the libowfs was not touched or changed from me.
Best regards,
Roland
