On the list it is. All the owfs code was pulled and built from CVS this
morning. python -V returns Python 2.4.3. I'm running on ubuntu 606 w/
patches, amd64 processor.
The first thing I was trying to do is run my code in the debugger. This
seems like it should be easy, but it went weird.
Here's my masterpiece of python:
#! /usr/bin/python
import ow
ow.init('127.0.0.1:2840')
s1 = ow.Sensor('/28.01AFAB000000')
s2 = ow.Sensor('/28.590AAC000000')
s3 = ow.Sensor('/28.AAC3AB000000')
s4 = ow.Sensor('/28.EF9CAB000000')
for sensor in (s1,s2,s3,s4):
print sensor._path, sensor.temperature
I run this in pdb, and start going through the program with "n". runs
the ow.init line and stops. As soon as I type n again, the program runs
to completion. No amount of breakpoints would work. What is going on?
Second, I extended the program to set the error codes, thinking this
might have something to do with the runaway code. I inserted
ow.error_level(ow.error_level.fatal)
ow.error_print(ow.error_print.stderr)
after ow.init.
pdb says:
> /home/scharf/house/dbcontrols/python/owtest.py(3)?()
-> import ow
(Pdb) n
> /home/scharf/house/dbcontrols/python/owtest.py(5)?()
-> ow.init('127.0.0.1:2840')
(Pdb) n
> /home/scharf/house/dbcontrols/python/owtest.py(7)?()
-> ow.error_level(ow.error_level.fatal)
(Pdb) n
AttributeError: "'module' object has no attribute 'cvar'"
> /home/scharf/house/dbcontrols/python/owtest.py(7)?()
-> ow.error_level(ow.error_level.fatal)
I located cvar in the __init__ code, but am not familiar with this level
of python...
Finally, I would like to use the simultaneous conversion functions that
Paul has fixed. How can I do that through the owpython interface? In
owfs, I do
echo 1 > /pathtomount/simultaneous/temperature
I tried a few random things, but was really grasping in the dark.
thanks,
jerry
P.S. Brad, there's a difference between line noise and white noise with
;s. ;)
