Jan,
I have done the update, but if the line that has the DS2450 drops
offline and then comes back online I still get values that don't make
sense.
/usr/local/bin/owserver version:
3.2p1
libow version:
3.2p1
Values from the DS2450 before taking the line off line:
4.25 2.25 4.46 4.52
Values from the DS2450 after putting the line back on line.
0.00 4.44 0.00 0.00
I am using the ow C API to read all of my Dallas 1-Wire devices. I do
a OW_init("/dev/cuao0"). I then go in to a loop and use OW_get to read
each device. I use the following line to read the voltages:
OW_get( "/uncached/1F.49D100000000/main/20.EDCD00000000/volt.all", &buf,
&s );
