[Owfs-developers] Temperature Sensor Rate of Change
Hi - I'm looking to monitor the heat generated by some pyrotechnics on stage at a performance of Romeo Juliet. There was a slight problem on opening night where the fire sprinkler over center stage went off. Too much heat generated from one of the fire effects. I was thinking of trying to use some DS18S20 sensors to monitor the temperature above the various fire effects. The sensors would be mounted to the ceiling above the various fire sources. The DS18S20 looks to have a range that'll support our needs, -55°C to +125°C. Since the sprinklers trigger at around +82°C that should work fine. But I'm concerned about being able to monitor temperature changes fast enough to provide accurate monitoring. The two aspects of that are how fast / often can I realistically expect to read the temperatures on a string of 5 to 7 sensors and how fast do the sensors themselves react to changes in temperature. Any thoughts or comments would be appreciated. Thanks! - Peter P.S.

The lighting effect of the water mist from the sprinkler being backlit by a blue light was spectacular.

And since it aims to be API-compliant with the original FUSE (Filesystem in USErspace) for Linux, it makes many existing FUSE file systems readily usable on Mac OS X. The core of MacFUSE consists of a dynamically loadable kernel extension. This release of MacFUSE includes the following components: Virtual file system (VFS) kernel extension Special-purpose mount_fusefs program Patch to the FUSE user-space library Patch to the SSHFS file system Developers, we want your help to make this project even more robust and useful.

[Owfs-developers] ownet - new python module to interact w/ owserver
Hi - I've committed to CVS the first draft of a new python module called ownet. It allows for interaction with a remote owserver without the need to have the core ow libraries and servers built on the local system. The code is very much in an alpha state so expect things to break. And if they do, please send a note to the list so that they can be resolved. This first version can only read data from an owserver. Setting values is not yet supported. The module is not automatically installed. Instead, you need to follow these simple steps: $ cd module/swig/python/ownet $ sudo python setup.py install There should now be a module called ownet in the site-packages directory of the python installation. Try running the modules/swig/python/ownet/examples/temperatures.py program. It should print out something like: $ python ./examples/temperatures.py kuro2 r: kuro2:/ - DS9490 r.entryList(): ['bus.0', 'settings', 'system', 'statistics'] r.sensorList(): [Sensor(/10.B7B64D000800, server=kuro2, port=), Sensor(/26.AF2E1500, server=kuro2, port=), Sensor(/81.A44C2300, server=kuro2, port=)] kuro2:/10.B7B64D000800 - DS18S20 22.4375 kuro2:/26.AF2E1500 - DS2438 21.0938 $ - Peter - Take Surveys.

Here's a hex dump of the data that's returned when I request a directory of the root. : 002a 0102 ...* 0010: 0005 6275 732e 3000 ec28 bus.0..( 0020: 0030: 0040: 002a .*.. 0050: 0102 0008 7365 7474 696e ..settin 0060: 6773 gs.. 0070: 0080: 002a ...* 0090: 0102 0006 7379 7374 syst 00a0: 656d em.. 00b0: 00c0: 002a .*.. 00d0: 0102 000a 7374 ..st 00e0: 6174 6973 7469 6373 atistics 00f0: 0100: 002a ...* 0110: 0102 0010 0120: 2f31 302e 4237 4236 3444 3030 3038 3030 /10.B7B64D000800 0130: 0140: 0150: 002a 0102 0010 .*.. 0160: 2f32 362e 4146 3245 3135 3030 3030 ../26.AF2E15 0170: 3030 00.. 0180: 0190: 002a 0102 0010 ...* 01a0: 2f38 312e 4134 3443 3233 3030 /81.A44C2300 01b0: 3030 3030 01c0: 01d0: 0102 01e0: c002 .. It shows (hex - decimal): version: 0x0 - 0 payload length: 0x2a - 42 type: 0x0 - 0 format flags: 0x102 - 258 size of data: 0x5 - 5 offset - 0x0 - 0 The payload doesn't look quite right since there's a whole lot more that's received from the server, 486 bytes total. The size of data seems to correspond to the length of the first entry name w/ trailing null - bus.0. But the rest doesn't make much sense to me. In looking at the hex dump of the data, I see the various values that I would expect in settings, system, statistics, etc. But I also see a whole lot more data that seems to be extra. I tried reading through the C headers and source but had trouble making heads or tails of the code that would be putting the buffer together to send over the network. I'm a wee bit lost here. So if anyone has a good idea of what's going on, let me know.

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('/28.01AFAB00')
s2 = ow.Sensor('/28.590AAC00')
s3 = ow.Sensor('/28.AAC3AB00')
s4 = ow.Sensor('/28.EF9CAB00')
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?
I haven't tried using pdb w/ OW. I typically put in print statements
and run the code again.
But I'll take a look into using pdb and try to find out what's going
on. I suspect that there's something about the relationship between
the OW module in C via Swig and the python interpreter.
Have you tried running pdb from within your python code? Something like:
#! /usr/bin/python
import ow
import pdb
ow.init('127.0.0.1:2840')
s1 = ow.Sensor('/28.01AFAB00')
pdb.set_trace()
s2 = ow.Sensor('/28.590AAC00')
pdb.set_trace()
s3 = ow.Sensor('/28.AAC3AB00')
pdb.set_trace()
s4 = ow.Sensor('/28.EF9CAB00')
pdb.set_trace()
for sensor in (s1,s2,s3,s4):
print sensor._path, sensor.temperature
The pdb.set_trace() lines should cause the program the run the
debugger. (Note that I haven't tried this yet myself. I need to setup
a system for trying out debugging under python...)
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...
I haven't seen this before. Let me dig into the code a bit and get back to you.
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.
The simultaneous feature of OW is rather new and I don't think the
SWIG based interfaces support it yet. While I'm digging through the
rest of the issues you raised, I'll see if this works and if it
doesn't I'll see about adding support for it.

[Owfs-developers] USB Device Access
Hi - I've been arguing with my 1-Wire USB controller once again and hopefully I'll win this time ;-) I generally run OW code from a non-root account to help prevent run away problems crashing or corrupting the system. Unfortunately, whenever a 1-Wire USB controller is connected to the system, root is the only account with read and write access. So I use the Linux Hotplug subsystem to fix that. I've written up a preliminary guide to extending the hotplug subsystem to automatically change the file owner and permissions on 1-Wire controller. It's attached here for review by the rest of the developers and community. I'd like to get some feedback and see if we can figure out a good place for this to live. Hopefully it'll provide some help to people setting up 1-Wire USB controllers on a Linux based system. Comments? Thought? - Peter Overview There are times when access to the 1-Wire USB controller has to be modified to allow a user other than root to have write access. This article presents a simple way to use the Linux Hotplug subsystem to change the file ownership and permissions on the file associated with a 1-Wire controller. Linux Hotplug Subsystem --- The notes presented here are specific to the Linux Hotplug subsystem and it must be installed for it to work. To install it on a Debian based system: apt-get install hotplug If you're running a version of Linux other than Debian, see the documentation for that version Linux for more details on how to install the Hotplug subsystem. USB Vendor and Product IDs -- The USB vendor and product ids are used by the Hotplug subsystem to identify which program is to be run when the device is plugged in. If you don't know the vendor and product ids for the 1-Wire USB controller you'll be using, you can use the lsusb program to find them. If lsusb isn't installed (typically in /usr/sbin) you'll need to install the appropiate package for your Linux distribution. On Debian systems, that means installing the usbutils package. apt-get install usbutils Once installed, run lsusb with the 1-Wire USB controlled plugged in: $ /usr/sbin/lsusb Bus 003 Device 001: ID : Bus 002 Device 013: ID 04fa:2490 Dallas Semiconductor DS1490F 2-in-1 Fob, 1-Wire adapter Bus 002 Device 001: ID : Bus 001 Device 001: ID : $ The 04fa is the vendor id and 2490 is the product id. Unplug the 1-Wire USB controller. Customize Hotplug - With the vendor and product ids in hand, the Hotplug subsystem can be modified to change the file permissions and file ownership. Create a new file called /etc/hotplug/usb/ow.usermap. This will contain the mapping of vendor / product id and the program to run. The file should contain a single line that looks like: ow0x03 0x04fa 0x2490 0x 0x 0x00 0x00 0x00 0x00 0x00 0x00 0x Change the 0x04fa to the vendor id and 0x2490 to the product id for your 1-Wire USB controller. Create a new shell program called /etc/hotplug/usb/ow. This will be the program that is run. Here's a simple example of changing the file group to ow and giving the group read and write access. #! /bin/sh if [ $DEVICE != ]; then # we have a device so setup security chgrp ow $DEVICE chmod g+rw $DEVICE logger ow hotplug: group set to ow and permission g+rw on $DEVICE else logger ow hotplug: error - no device fi The file has to be made executable via chmod +x /etc/hotplug/usb/ow otherwise it will not be excuted by the Hotplug subsystem. Also, don't forget to add a group called ow and add users to the group. Once this is setup, you can plug the 1-Wire USB controller into the computer. After a bit, you should see a message in the system log file that looks like: Nov 29 10:06:27 kuro2 logger: ow hotplug: group set to ow and permission g+rw on /proc/bus/usb/002/013 and that can be verified by $ ls -l /proc/bus/usb/002/013 -rw-rw-r-- 1 root ow 147 Nov 29 10:06 /proc/bus/usb/002/013 - Take Surveys.

Just to follow up on using pdb, I see the same problem that Jerry reported.
Here's the source:

pdb.set_trace()
ow.init('u')
r = ow.Sensor('/')
for x in r.sensors():
print x
And the output:
$ python x.py

Adding a pdb.set_trace() before the print in the for loop works better.

This article presents a simple way to use the Linux udev subsystem to change the file ownership and permissions on the file associated with a 1-Wire controller. Udev Subsystem -- The notes presented here are specific to the Linux udev subsystem and it must be installed for it to work. Several leading-edge Linux distributions have udev installed as part of the base system including FedoraCore 6 and Suse 10.

Re: [Owfs-developers] Building on OS/X
Ok, I've fixed the makefile problem - there was an extra space after a backslash. The nested function seems to be a bit over my head right now. I'm not seeing a reasonable way to pass the pn2 variable to the action function. But I will take another shot at it tomorrow evening unless someone else gets there first ;-) - Peter On 10/7/06, Peter Kropf [EMAIL PROTECTED] wrote: I'll start looking into it tonight but I'm not going to be able to spend too much time on it.

Hi,
I have just the beginnings of an airport gate controller, but one of my relays
burned out, so haven't progressed too far yet on the code.
Anyway, in addition to the hash problem, I'm getting occasional dropouts from

So what happens is, when I use sensorList I get an exception because None is
not a string and so doesn't have a split method.
I think the python library needs a specific exception that can be tested for
when a
sensor path is no longer valid or a communication timeout occurs.
So, if I query a sensor that suddenly isn't there, I want a specific
exception I can
catch, not a generic attributeError.
Consider the output pasted below, which corresponds to this simple program

Re: [Owfs-developers] RE: I can`t compile the owfs
Can you check the version of automake that's being used? You look to have both 1.4 and 1.9 installed. Run: automake --versionand check the version number. OWFS doesn't work with version 1.4. (I recently ran into this problem on one of my systems here...) If
1.4 is the default version, you have two choices - deinstall the 1.4 version or run the 1.9 version explicitly. To run the 1.9 version, change the bootstrap script to:#! /bin/shrm -rf *cacheaclocal-1.9
autoheader autoconf automake-1.9 echo Run './configure' and 'make' to build owfsand let us know if this works for you...- Peter

Re: [Owfs-developers] Accessing error_level and error_print from Python / Perl / PHP / TCL
I'm not sure I follow. What kind of problems are you thinking of for
non-interactive programs?
For the things that I'm working with, the code will run as daemon
processes and will start with something like:
import ow
ow.error_level(ow.error_level.connect)
ow.error_print(ow.error_print.syslog)
ow.init('u')
to be able to send connect level messages to syslog, actually
daemon.log. This allows me to have a log of messages for what was
going on with the process from the owlib point of view.

Subject: [Owfs-developers] Accessing error_level and error_print from Python /
Perl / PHP / TCL
I've modified modules/swig/ow.i to provide access to the error_level
and error_print global variables. This was done so that direct access
to owlib from the language bindings will be able to set the variables
as appropiate.
In the Python world, it can now be used as:
[EMAIL PROTECTED]:/space/src/owfs/module/swig python
Python 2.4.1 (#2, Mar 30 2005, 21:51:10)

Type help, copyright, credits or license for more information.
import ow
ow.error_level(ow.error_level.connect)
2
ow.init('u')
ERR: Failed to set configuration on USB DS9490 adapter at 002/004.
: Operation not permitted
This sample set the error_level to connect (2) and then tried to open
a USB adapter. Since the current permissions on the USB device is
restricted, this failed. Without setting the error_level, no message
would have been displayed. There's also an example under
modules/swig/python/examples/errormessages.py.
I haven't done anything specific to the Perl, PHP or TCL bindings. If
there's something that can be done to help the users, I'm hoping that
the binding author or someone more knowledgable than me will make the
needed changes.
And, if anyone else is using the Python bindings, I would appreciate
it if you could try this out and make sure that it works.
