Hello
I build myself a serial->1Wire adapter using a DS2480B and a MAX232. I have
a 18B20 (temperature sensor) connected to the bus. I am supplying 5 V
externally -- I am not using the parasitic mode.
Now, I am trying to commission it using owhttp:
./owhttpd -d /dev/ttyS0 -p192.168.1.1:3000 --error_level=3
The adapter seems not to be recognized (see log below).
I wonder, if I have a problem in my circuit or whether this is a
configuration issue.
Thank you
Tilman
