Hello everyone,
have some of you made an adaptation of this project :OWFS-Pi.project ,
to adapt it to the DS2482-800 integrated circuit?
Or can you tell me what changes need to be made?
in: "temperature sensor" I get the information from "/ mnt / 1wire".
"temperature sensor initializes" and "temperature sensor read temperature" do not seem to be useful ???
maybe I'm wrong ?
must a "temperature sensor FB" be created per DS18B20 sensor?
thank you.

some new info,
by changing the path of the folder "onewirefilepath" from '/ mnt / 1wire /' to '/ mnt / 1wire / uncached /' I have almost instantaneous values, also adjusting the values of "tonreadtimer".

however, I need your help, regarding the number of sensors that can be managed by the program,
the program works well with a sensor, but how can it handle multiple sensors?
all help will be appreciated, thank you.
