Greetings,
After several tries I found that my USB 1-wire master is not working
reliable on Raspberry Pi - seems in some cases USB bus power is not enough
(syslog tells this).
Before going to use an externally powered USB hub, I tried to use GPIO
bitbang method to drive 1-wire.
I used w1 libary (w1-gpio and w1-therm), but found that OWFS cannot really
work with it.
I tried
modprobe w1-gpio
modprobe w1-therm
owserver --w1 -p 4300
owhtpd -s 4300 -p 80
But when I try to connect via HTTP, RPi freezes, and I have to unplug it.
Same if I use owfs instead of owhttpd, when I try to go to the mount point.
In the same time I'm able to see the files what w1 mounts (/sys/bus/w1/devices)
and read values without problem (But I have to say, one time it was frozen
using this method as well)
I upgraded kernel, packages, but no help.
What can be wrong?
Thanks,
Attila
