[Owfs-developers] Owhttpd works on a Raspberry Pi Zero

2024-05-13 Thread Gregg Levine

Hello!
This list is too quiet so I thought I'd post my latest and greatest
project. That of installing the owfs programs on a Raspberry Pi Zero.

Currently I have a traditional serial adapter plugged into an FTDI
based serial adapter with the DE9 connector. Basically the program is
reporting the power running to a boost device from Adafruit at 3.68
(It shows 4.7 unloaded.) and the room temperature at 24C on a DS2436.

Re: [Owfs-developers] Raspberry Pi busmaster GPIO connector

2024-04-02 Thread Gregg Levine

Hello!
I returned this to the list, because I wanted everyone else to
comment. Right now I'm busily creating my ideas. Your gadget, which I
see is for sale from a good company, is a good idea, but I'm looking
at this from the perspective of how Adafruit suggested it originally.
Also I've enabled composite video output on the one I'm using today,
and was using earlier to perfect the ideas behind composite video out
from these devices. Now that's something worth writing about,
elsewhere.

Consider this, the original company developed a part for "smart
battery packs", that's the direction I'm going in for this job.

[Owfs-developers] Raspberry Pi busmaster GPIO connector

2024-04-01 Thread Gregg Levine

Hello!
I've a new project taking shape at the moment. And it involves making
use of OWFS on the Raspberry Pi, a Pi Zero Wifi WH device in fact. And
I recalled that when I enabled the GPIO settings such as the Serial
port there, and typically the I2C settings, I would see but not enable
the one for One-Wire. Now the question is one of which GPIO one that
the system selected. The website makes a reference to someone's work,
but does not provide references.

2022-03-29 Thread Gregg Levine

Hello!
How'd you wire yours? He's got a strange view of that device. Well
mostly as the ones I would use are all parasitic powered, which was of
course not driven by a VCC3 line someplace. And the line he chose
could be used for One-Wire communications via OWFS, as it's
documented, someplace.

[Owfs-developers] DS2423 question

2020-06-23 Thread Gregg Levine

Hello!
On a page inside appnote AN3845 from Maxim back when they were still
making the DS2423 parts, the schematic shown includes a pair of
Schottky diodes, they were the BAT54 series. Also a pull-down resistor
of 1Meg.

Now I can certainly grok the reasoning behind the pull-down resistor
for the part to work properly, but what about the dual diodes? The
other problem is that these are of the small outline style, which
means they are available as surface mount styles. (They might be
available in the standard mountable rather than a surface mount style.
I've not checked further.)

2020-06-22 Thread Gregg Levine

Hello!
Okay group, I'll defer to all of you on this. Something else, do any
of you know who does the packaging for Debian? And that for the
Raspberry Pi families? I ask because I read over of the series of
messages on making things work on one and the problems related there,
resemble some of the reasons why I do build from source, instead of
using preexisting packages.

[Owfs-developers] Bugfixed release not the one for download?

2020-06-22 Thread Gregg Levine

Hello!
As with everyone during this time, I'm busily exploring a project or
three. In this case I decided to spin up one from either last year or
two years ago, concerning OWFS and using one of the 3.2 releases on a
Raspberry Pi.

I decided to check to see if the project page for OWFS had anything
new, that is newer than the OWFS-3.2P2 one that I'm busy building.
The release device from the page wanted to send me the previous
release. Since I'm still down as an admin I decided to see if I could
change things to reflect that version. I decided against it because I
did not want to break any of the pages on the site.

About that project. That will be discussed in a separate message.

Hello!
Thank you for confirming my thoughts on the VB stuff. As for the next
release, I'll download that today, and add it to my collection. As for
creating an GIT issue, I'm going to adopt a wait and see to this one.
It's because Norton can be told to ignore stuff.

Hello!
I'd be delighted to do so, except all I have is what I stated above,
and perhaps the responses (as idiotic as they are) from Norton itself.
I also followed the same steps to download a new GIT blob onto a
folder on a Raspberry Pi to which I'd previously gotten OWFS to work
that way. I've since compressed it into a TAR file which was also
BZIP2 compressed.

Depending on what your response is, I'll retrieve it and try again.
This time extracting that over what is already there.

Can you tell me, also, if there where any commits to the directory recently?

[Owfs-developers] I just downloaded the OWFS source code from the new GIT location...

2019-07-15 Thread Gregg Levine

Hello!
Okay I found and downloaded the OWS source code from the new GIT
location. But during the process of doing that, I found that Norton
insisted that there was a Trojan hiding in the VB example of one of
the OWFS programs. I am convinced that this is a rare false positive
for the Norton antivirus program.

Incidentally this was downloaded onto a Linux on Windows instance
which is posing as SuSe SLES 12 server when running. I've built and
run the latest release on it and actually gotten it to work.

2019-02-21 Thread Gregg Levine

Hello!
it is interesting that you mention OpenWRT in this context. Early in
the cycles regarding OWFS one of us got it to work on an appropriately
configured WRT54GL router. That meant following a website's
instructions to open the rig and find and attach to it the two serial
ports it needs to continue.

Oh and that also includes constructing the adapters needed to
translate the 3,.3V logic levels on the Router board to the RS232
levels need to make the serial adapters work.

To find out more simply instruct Google to search for WRT54G serial
port and there you are.

I don't wear the List Manager's hat here, but I find this extremely
interesting, and will support it.

[Owfs-developers] Confirming a working release on the latest release of Raspbian

2018-11-12 Thread Gregg Levine

Hello!
I can confirm that webserver function of the latest release of OWFS
does indeed work as built on a Pi Zero W running the latest release of
Raspbian.

Basically I'm not at all thrilled as to how the Debian packages lag
the releases of our utilities for minding the purposes of the One-Wire
devices. So I decided to build it from source and allow it to install
the programs in the usual places.

I picked three cans at random, one contains a DS2415 device which it
turns out is not readable by the Windows release as running on Windows
98SE. And then a pair of devices which were, I believe the computer
program said they were both DS1992 types.

And using three through the hole holders I promptly stuck them on a
breadboard and wired them together appropriately. Oh and I used an
RJ11 breakout from Sparkfun to connect them to the DS9097 device.

[Owfs-developers] One-Wire FS via Raspberry Pi GPIO

2018-10-08 Thread Gregg Levine

Hello!
I found a page who explains within reason how to make (some) use of a
Raspberry Pi GPIO point as a One-Wire hookup:
https://pinout.xyz/pinout/1_wire

Naturally it does not go into a enough detail which is why I wanted to
ask the people here about it.

I of course have the serial devices that most of us started with, and
can order a new USB adapter and can convince the company to send me
samples of the I2C chips for that purpose.


But since the Raspberry Pi folks tend to think that their device needs
no help in accessing such things I decided to give it a try.

[Owfs-developers] git pull returns 502 error message

2018-03-01 Thread Gregg Levine

Hello!
I have the most recent numbered release on a Pi3 (now on a Pi Zero W)
running and working. However since I previously also released the
newest code via a git clone when setting up the directory.

Now however I need to update things, and it is returning that error
message. It means bad gateway.

Incidentally for those of us in NYC, I demonstrated it on that Pi3 for
a group of people as part of my commitment to participation in the
Hack A Day NYC meeting, which was subtitled "Bring a hack". This was
using the ttyUSB0 connection which is what I also use here, when the
laptop is running Slackware.

Now I want to reduce it to working on a Pi Zero W and found one for
sale with the headers on it already. First via ttyUSB0 and then via
i2c since there's a company who make prepared sleds for the mounting
of chips in SMT formats.

Incidentally Paul if you're listening, I gave a generous nod to your
efforts to create the OWFS software for your home project.

[Owfs-developers] Project updates

2018-01-17 Thread Gregg Levine

Hello!
Okay, here goes:
On my Slackware-11 box I've gotten 2.9p0 to work. It will using the
HTTPD one, display both the connecting device a DS9097U who was a
DS2502 inside it, and a DS2423, and finally a DS2436.

The DS2436 confirmed that the air temp was 25C or 77 degrees F, and
that the battery connected to both it and the DS2423 had a voltage
level of 4.1.

Running on a Raspberry Pi3 who's release is not the same as the one on
their site, I've gotten 3.2p1 to build properly. We won't go into
details concerning why the original binary owfs was disabled.
Currently the webpage for the HTTPD one just shows the connecting
device which is the same a above.

As for the Intel Linux one, I'll need to check to see what it has down
in the directories. But I'll update everyone later.

Incidentally the latest SF update included the garish settings.

Re: [Owfs-developers] python-ow failure with new Raspbian Stretch

2017-12-17 Thread Gregg Levine

Hello!
I'd go a bigger step further and make them optional by way of how the
configure script is managed. I manage three platforms here. My desktop
a 32 bit machine running Slackware 11.0 Linux, and this laptop, that
also runs Slackware 14.2 in 64 bit mode. And of course any number of
Raspberry Pi platforms.

We'd a poll of some kind asking how many people use Python in the OWFS
community, and even TCL and then PHP. Once we've got those numbers,
we'd have some idea of what to do next.

Of course the merely obvious question is why the swig bindings are not
under active development. The incredibly obvious question then is who
was performing that task.

[Owfs-developers] Releases and Slackware-11.0

2017-12-14 Thread Gregg Levine

Hello!
I can now safely state that owfs-2.9p0 will build on Slackware-11.0.
Everything else from that sequence kept crashing during the build
process in approximately the same places.

If needed I can provide extracts from script output text files with
those entries. I believe the later releases up to the 3 series would
build on the 12 pair of releases, but this concerns itself with 11,0.

[Owfs-developers] Releases and Slackware-11.0

2017-12-14 Thread Gregg Levine

Hello!
I am busily working my way towards constructing an embedded system
around Slackware. I don't know if is doable on a Raspberry Pi, and
while its certainly doable on Intel platforms after 2009, the target
is leaning towards a system that was built before that.

I already know that the releases that start with 3 will not build
there, but will build on the Slackware-14.2 64 bit system I do run on
this laptop.

I've accumulated a batch of script output text files from the earlier
releases indicating what broke and where. I grok that these are old
issues and that the chances of fixing them are practically nonexistent
but would the list be interested seeing them when finished? (So far it
is not finished.)

[Owfs-developers] DS2423 questions

2017-12-12 Thread Gregg Levine

Hello!
Can anyone recall when the company decided to discontinue the DS2423?
My datasheet has on it the legend that it is not for new designs.

Right now my design can count when it sees magnet turn off its switch,
but the viewer complains. That's the original 32 bit Windows one as it
happens.

What was the appropriate external resistor size for it to work appropriately?

Apologies to all it is very early in my region and I normally do not
post these messages now.

Agreed on all points. However there is (idle) speculation that Source

Stefan you mention that there's a name there that you've never seen on

Also we note that (sadly) Paul is gone. When was his last posting?
I've also noted as before that I'm now a project admin, I believe that
that the two are connected.

Re: [Owfs-developers] owfs is DISABLED

2016-07-25 Thread Gregg Levine

Hello!
Mick no you are not.

The rules for building OWFS on a Debian based variety of Linux have
never really changed since before the release of the first Raspberry
Pi device.

However we need to change the rules appropriately for the Raspberry Pi.

And we need to get things updated on the website, as Slackware 10.2 is
quite old, I've gotten the proper releases to build on 11.0 and even
the 64 bit 14 series ones.

And additionally this is being written on a Slackware64 system running

Re: [Owfs-developers] Supported devices

2015-07-05 Thread Gregg Levine

Hello!
Thank you. I'll look at it next.

However the DS2432 is this guy: 1Kb Protected 1-Wire EEPROM with SHA-1
Engine. One reason why its unsupported is that to use it properly the
user needs to sign six or even eight different forms before they
release the full datasheet. Those forms would be an NDA of some sort.
Then. Now its clearly shown to be:
NRND

Not recommended for new designs. The product is in production and
available, and is not scheduled to be discontinued. We do not
recommend using this product for new designs because there is a better
or more economical alternative, or because demand for the product is
decreasing. We list recommended replacements when possible.

Their phrasing.

Okay it seems my chosen part for the battery pack is indeed supported
by us. They do not.

 For the current list of non-supported chips, look at the

 So far, DS1954 and DS1957 have only minimal support (whatever that
 means) and DS1961S, DS2432, mTC001, mTC002 are unsupported.


 And there once was a dual-port RAM (1-Wire/3-Wire), I think it was the
 DS2504, which was discontinued before owfs even started, so owfs haven't
 got support for it. Ever. There isn't a datasheet available anymore. If
 someone has documentation that chip ever existed, please tell.

[Owfs-developers] Supported devices

2015-07-04 Thread Gregg Levine

Hello!
Can someone confirm or refute this statement?

OWFS supports all devices from the vendor (MAXIM once Dallas
Semiconductor) no matter how old, and even if they were discontinued
by them.

In this case I'm looking to support a (seemingly) 9V battery box via a
DS2436, the Windows (!!) software running inside a VM confirms that
the device sees the battery and of course all of ancillary details
associated with the device. This includes the voltage of the battery,
and the temperature of the associated setup, in degrees C as it
happens.

There's also graphing indicating a study on time versus voltage and
one for the same versus temperature. Plus user defined registers.
That's the original Windows (!!) software at work.

The setup would also include a bundle of DS2406s at work as well.

Paul, FYI, that is why the notes on the page with my name on it
include those four.

The final controller would be a Raspberry Pi with the current release
in its repository installed, but now its a pair of VMs running the
original software.

2015-06-13 Thread Gregg Levine

Hello!
To further expand on everything, we use FUSE a user level virtual file
system to store and manage all of OWFS. The module and its connections
to the kernel handle everything that OWFS uses to create itself. For a
better idea of what's going on set a debug setting as appropriate and
you should see something.

What do you think Paul? Did I miss anything? Is anyone confused here?

To expand on Colin's point, the files in owfs are created on the fly by the
program. They don't exist on disk. When you read a temperature, the system
makes it look like the file contains a number, but actually the program
reads data from the 1-wire bus to get the value.

The UNIX file system needs a place to hang the top of the filesystem,
/mnt/1wire seems to be what you are using. Everything below that is
virtual and doesn't exist until the owfs is run. (Actually any real files
below that point are masked over by owfs and would be unmasked when owfs
isn't running -- but that just confuses things).

They are not real files that actually exist on disc anywhere. Owfs just

2015-06-13 Thread Gregg Levine

Hello!
Colin that's an amazing write-up regarding the Pi and One-Wire and
OWFS. It, almost compels me to figure out how to safely mount one of
the DS2483 chips I have here and work out how to attach it to the PI
have here, via the I2C lines on it.

Oddly enough Sparkfun sells a bare breakout board for that package
style, I've suggested that they should sell one wearing a DS2483, but
no takers so far.

Oddly enough Adafruit has used the same breakout board style (But
that's all it is) for the DS2413 so we're fixed that way.

Hello!
I'm glad my advise worked for you Eric.

Please write up more completely what you did. Paul we need what Eric
collided with, both those road blocks, and this example of success for
our website.

Now as to your small question, sadly I can't answer that one, but I
believe the others can do that.

Do have a good holiday of course.

 Hi everyone :-)

 SUCCESS ! ! !

 Now compiled, installed and running smoothly !

 Thanks everyone such much !

 Please let me know if anyone of you wants a donation.


 Problem was:

 By not selecting the locals in raspi-config correctly, Perl was no running
 properly.
 This prevented the header files from the installation of libusb-dev
 to be placed in the right place. Thus I alway got the message after
 running ./configure that USB was disabled.

 After running

 sudo apt-get install libusb-dev

 again, and then /configure and make everything runns smoothly.


 By the way a small 1 Wire question:

 Am I correct in the understanding that 1 wire is 'plug and play'.
 Meaning that slaves can be disconnected at any point with no severe
 consequences despite a possible data loss of that slave?

 My love to,

 Eric

Hello!
Exactly. Every time I startup a new image, I promptly set my location,
that is where I live, US, for language settings, and that of keyboard

Theoretically it should be possible to set the image to match exactly
where you are. Don't worry about the cgroups and cgroups2 error

 I will check it out! Should find some Google answer I suppose ...

 But, yes I did  install the newest version of Raspbian from 30.3.2015 !
 But these two error messages are displayed since the first boot anyway.

 Could it have to do anything with the options chosen in the raspi-config

 Because I suspect it has to do something with the language setting chosen
 there right?

 Thanks so much for your help guys!

 Will keep u updated.

Hello!
Are you running the latest release of the operating system from the
Raspberry Pi pages? The basic install, the one that starts the
configuration tool does indeed contain the basics so someone can get
started building stuff.

And yes PERL is indeed a requirement as is M4 and auto* tools. Make

 You certainly need a capacitor for debouncing, the resistor alone - it

 (With the capacitor but without the resistor, you get a very slow
 debouncing effect, as the DS2423 has a very high-ohmic pullup resistor
 built-in. So you can try with a 100pF capacitor alone, but I don't
 recommend it because of the tolerance of the internal pullup.)

 Wait, where do you apply that resistor? From DS2423 Vbat pin to actual
 Vbat? That's wrong.

 The 5k pullup resistor on DQ is mentioned in the datasheet (page 25,
 note 5). That pullup *may* be needed in your application because the
 DS2423 has no Vdd pin, just a VBat pin. That pVbat pin is for retaining
 the internal RAM contents only. All the power to the bus controller
 inside the chip is taken from DQ.

 Effectively, you will need that pullup if you plan to hot-plug the
 DS2423 device to the bus, because without the pullup, it may pull down
 the bus too long and so, generate a fake reset pulse. If you don't
 hot-plug, you don't need the pullup on DQ.



 On the counter inputs I use a 10k pullup and 10nF capacitor to GND to
 debounce simple switches.

 Kind regards

 Jan

[Owfs-developers] DS2423 strangeness (again)

2015-02-17 Thread Gregg Levine

Hello!
I am again investigating the strange behavior of the DS2423 I have here.

So far the thing does much as it did do earlier on. However I made use of
Google giving it ds2423 resistor as the search key (inside the quotes)
and it promptly presented me with an interesting series of responses. One
looked almost promising, which is here:
http://www.phanderson.com/bx24/ds2423.html

In it he writes that it needed a 4.7K pull up resistor to Vbat. Well I
found one and attached it. Same strange behavior as before. But what I'm
concerned with more is what are the rest of us doing with their parts? What
resistor value was selected for all of yours, and what is the part doing?

[Owfs-developers] Running owfs-3.0p0 on Slackware64-14.1

2015-02-16 Thread Gregg Levine

Hello!
I can safely say that after an interesting series of steps I can now
run the current release on this laptop as its also running
Slackware64-14.1 via an external Flash device.

Those steps involved having to make sure that the underlying library
was properly made and installed. And to make sure that the routines
needed to install everything also worked.

Currently I have the webserver running.

As for making a DS2423 chip work, I've found online the necessary
hints to enable it to count properly, both with a switch in the on
position and then its off one. It seemed that my search talents
worked, this time.

Re: [Owfs-developers] iButton - n00b question

2015-02-15 Thread Gregg Levine

Hello!
A good question. One I've asked myself countless times, before Paul
wrote his excellent tool set and realized there was a better way to
manage certain storage methods.

Let's say you own an iButton of the type who contains a DS2401
electronic serial number. Inserting it into the reader will prompt the
computer to examine it, and add it to the list of displayed devices.
The serial number on it, will be the displayed along with everything
else known about it.

For example one of the many ideas that the company who originated them
had was to contain a standard real time clock that would contain all
of the features their real time clocks have and indeed that was the
case.

A third party company makes a specialty reader who when pressed
against one of them is told the time of day and encloses it in its
files. Further it can be used in place of the recording clocks that
watchmen used for an eternity of walking around buildings. And in fact
my food store uses them for their day-to-day activities as applied to
that one.

At one point the company was working with a company to make up
doorlocks that would only open when a matching button was shown to it.

It gets even stranger.

At the height of the Java business, they even made a button who would
contain an application, and indeed the fun one was to have the thing
send the host computer to show the owner's website in all its
(typically badly) written glory.

Incidentally those numbers that each device wears have a story behind
them. It seems that during the process of development someone there
discovered that they resembled the codes worn by Ethernet cards so
they made arrangements with the authorities behind that to register
them accordingly. They are as seemingly random as the UUID entries
that can be created using the appropriate software, but that's where
the two part company.

 Hi Daniel,

 Gregg answered the more general philosophy of 1-wire architecture. Let me
 address your questions narrowly.

 All the 1-wire chips (well, almost all except the DS1821) have a unique ID
 that can be queried by the 1-wire discovery protocol. When you ask for a
 directory listing in OWFS it has all the 1-wire devices enumerate
 themselves.

 You can ask for a directory listing periodically (preferably uncached) to
 check the available devices. Although plugging in  new device will send a
 presence pulse it's unreliable (easily lost in other bus traffic) and thus
 not used by OWFS. Periodic polling is the best way.

 The value of sensors, the frequency for reading data and the frequency for

 punt the system sometimes in an bad timing so that for an longer time no
 data can be read without an timeout.
 By that it take here no matter, if the bus is only be read from owfs or if
 it will be first read in by owserver and than
 owfs and owhttpd will read from the server.

 Hi,
 owfs and owserver are not running in same time. I started with owserver and
 used it for several months. Maybe after 1 month ago, I switched to owfs and
 it did not helped. Currently I run only one instance/process of owfs.
 Wiring problem ? I'm not sure, because sometime it run ok, so if it will be
 wiring problem this will not  happen.

 @Roland
 Data was read with owget/owread when I run as owserver, now are they read
 with cat /mountpoint/sensor/temperature, because I it is running as owfs. I
 always thought, that cached data are stored in ram, that they are
 periodically read by server, but when I ask for data, it first time take
 several seconds, then they are displayed, and when I ask second time, then
 they are cached.

 BTW, my polling frequency in Zabbix to read data is 30 seconds.

  Hi,

  I have tried it running as owserver and read data with owread/owget, and
  running as fuse mount point and read data with cat commad. Result is
  same. To store values I use Zabbix.
 How will be the data read in by Zabbix.
 An similar problem is by collectd with the onewire plugin.
 My suggestion by both will be, that the cached data can be not read in the
 time, owfs will update them.
 Maybe the update there is not only an copy from the uncached data to the
 cached data at one time.
 There will be the similar way to read in the data like the uncached
 version and this will take longer time
 (By more sensors it will take an long time).

 Can this suggestion be right?

 Hi!

 Another specific scenario where slurp is required, I guess, is in
 DS2480_set_baud, where we cannot rely on proper read-back, if the baud rate
 changed.
 So, as you say, slurp is probably required, and it's not worth trying to do
 proper reading, which is bound to fail anyway.

 Thus, my suggestion is to increase the slurp timeout so we can be sure that
 we actually any pending bytes.
 If slurp is only used during initial resets (which is the case for the
 DS2480 and the LINK code, I haven't studied any others), then it is no harm
 to increase this to say 100ms.
 HOWEVER, if any other device-code is using slurp during the normal
 communication flow, a longer timeout would of course hurt.

 The thing with the FTDI parameter is that you cannot really change that
 unless specific support for libftdi is added. Currently the DS2480 code only
 works with a generic serial device, with no information on the underlying
 hardware. So, hard to know when to apply ftdi changes, and even harder to
 identify which port to change..

 As discussed here previously, I've got some ftdi code in owfs working,
 although for the LinkUSB. Should be trivial to port to the DS2480-code, or
 probably most serial-based code. The question is if it makes sense to add
 chip-specific code, when this is only usable if you actually use a
 USB-serial-adapter built on that chip. In the LinkUSB case it makes more
 sense, since the actual 1-wire-product LinkUSB is built around that chip.

 Anyway, by just raising the slurp timeout, we solve the main issue.
 Controlling the FTDI timeout would however give some speed increase, some
 simple tests shows that with a default of 16ms, the DS2480b reads
 /28.xxx/power in ~77ms, vs 27ms with 1ms timeout.


 Regarding 0-baud, I think it's only done from serial_powercycle, not sure
 why though. Power-cycle adapters powered directly by the serial-port?
 Since I don't know the use of the code, I cannot really say if this is an
 issue worth addressing. B0 is defined in termios.h so it should certainly be
 a valid value.

 Thank you, Johan, for the detailed tests.

 The idea of slurp was to collect any pending serial traffic and allow
 communication with the bus master to be synchronized. I agree that matching
 expected response exactly is optimal, but that supposes that you start from
 a known clean state. I found in some of my early tests that old data was
 still delivered with the system was restarted.

 Obviously, testing is hardware-specific. The timing was adjusted based on my
 tests -- not very scientific.

 It sounds like you think we should adjust the slurp time-out, and perhaps
 some of the FTDI timing parameters. Also there is a 0-baud issue which we
 should look at fixing on our end as well. Is it the serial BREAK or baud
 changed that does it?

 Hi,

 I've noticed some problems using a FTDI based USB serial dongle together
 with a DS2480B based adapter (also known as DS9097U).
 On startup the device was not recognized at all, complaining about wrong
 responses. Anyone else seen these issues?

 I've debugged the problem and found the cause.
 On startup, this is what happens:


   DEBUG: ow_ds9097U.c:(287) Attempt 0 of 3 to initialize the DS9097U
 TRAFFIC OUT write bus=0 (/dev/cua-labdesk)
 Byte buffer anonymous, length=1

p
   DEBUG: ow_tcp_read.c:(114) read: 1 - 0 = 1
   DEBUG: ow_ds9097U.c:(459) wrong response (70 not 00)


 After each TRAFFIC OUT byte above, a COM_Slurp() is issued to read and
 remove the response.

 The response to the 71 command should be 70.. Which is what we see..
 except that it fails to slurp those bytes, it's actually
 reading them as the response to the next command.

 After some further debugging and added printf statements, I realize that
 COM_slurp fails to read the bytes, and instead just timeouts (1ms).
 I've been working on my pure-ftdi-branch for the LinkUSB, where I've
 learned that the FTDI chips by default have a 16ms timeout for small
 transfers, making them not very efficient when dealing with few bytes
 like this.

[Owfs-developers] Using a USB to Serial adapter with a RasPi and OWFS

2014-08-13 Thread Gregg Levine

Hello!
Normally when trying out ideas regarding OWFS on my Raspberry Pi model
B I use an adapter based on the FT232 chipset. I get the same results
as when I'm using the same adapter.

This is connected to a DS9097U9 adapter.

Okay that's a start. I'll take that into consideration. However you
shouldn't had to do that as the kernel contains the drivers for the

Re: [Owfs-developers] Using a USB to Serial adapter with a RasPi and OWFS

2014-08-13 Thread Gregg Levine

Hello!
Thank you Jan Kanziora for bringing that to my attention. As it
happens that's next. I'm used to using an FT232 based adapter on this
laptop for the odd One-Wire application, and also under Linux on a
different system via OWFS.

I figure if it gets to the point where this idea works, I'll take the
time to study how its port is configured, remember that's the console,
and everything gets shown there so it gets decidedly complicated.

And parenthetically my (older) sister who bought me the widget as part
of a starter kit for my birthday two years ago, badgered me something
awful over the weekend about not doing anything special with it. So I
figured I'd start here, and thence move on to being available via the
HDMI port on its side. Right now he's working headless.

My HDTV set only has two HDMI connectors, one for the Cable TV box and
another for the odd blue-ray player the vendors thought.

Which is why I ended the earlier one regarding photos and stuff. Right
now it'll be the top favorite around here, switches and temperature of
the room, if the system does end up using the GPIO port for serial to
One Wire via a MAX232 as you suggested, it will be other stuff
including room temperature.

For that it will be a second device in a nice box.

Keep those good ideas coming please Jan. And next time you're visiting
NYC I owe you lunch in a very special deli.

 By the way: If you don't need the serial console (hardly), the Pi has a
 real RS232 on the GPIO pins. Needs a MAX2232A converter, though.

[Owfs-developers] Wiring the DS2423

2014-07-22 Thread Gregg Levine

Hello!
According to an applications note concerning the part and one person's
efforts, the counter functions are supposed to work on it, when the
external input lines are indeed switched, probably indeed grounded.

Can someone independently confirm that? The application note is AN3845.

From that perspective I was indeed able to confirm what I was doing
before, is indeed correct. However it bothers me that the software
originally written for everything else and well before Windows Seven
confirms it by simply complaining about no device when the switch is
open.

I want to confirm that the whole business works before handing the
connector a DS9097U-9 to my running Linux system. (Which I'll need to
have built everything for it first)

[Owfs-developers] Support for the DS2438 and the DS2436

2014-06-22 Thread Gregg Levine

Hello!
New project time here. I'm busy trying to come up with something that
will harness the amazing collection of parts here and I've got a batch
of DS2436s that I want to apply, one of them certainly. Or the DS2438.
I've got a batch of them as well.

So I'm wondering. Am I correct in my belief that support for these
parts is still included in our code series?

Re: [Owfs-developers] New release 2.9p4

2014-04-29 Thread Gregg Levine

Hello!
SF delivers both Git and CVS and probably SVN (still) and probably any
others we can dream up. So when was CVS depreciated? I believe I
managed to update the CVS one last night, and even tried to build the
P3 release of 2.9 on my Slackware 13.37 system. (Currently the only
one running.) It complained about libtool errors as related to age and
so forth, it even insisted that I obtain a new release of such from an
Ubuntu system.

Paul is that where the original code is being built? (I'm on Slackware.)

Hello!
Regarding your router running Linux issue. Did you by chance ask
Amazon about it? There seems to be scads of them there. But I'm more
surprised by your Ham Radio software collection. The repository for
software at the UC SD site, (University California Sand Diego) It
turns out that most of what you've collected is available there. Look
for the home page for Phil Karn (KA9Q) and as it happens his ideas are

 or maybe its Klingon code and it escaped :)

 For some 5 years I've been using mongoose in my home made irrigation
 controller, starting from version 2.8 and updating over the years to the
 current 5.3.

 It started as an embedded project running on a Linksys WRT54GL router that
 was modified to interface one of its internal serial ports to a 1-wire
 master controller chip. This used the Public Domain Dallas software and
 its worked very well but Linksys routers are getting difficult to find (as
 I discovered after a big lightning storm took out a couple of mine).

 As a result, I've looked at using a more modern router with a USB port,
 Still running OpenWrt software but with a Hong Kong USB to 1-wire
 interface rather then the home-made one inside the Linksys. Along with the
 more modern hardware, I've decided to move to supported software as well
 and ported everything to OWFS.

 Apart from finding a big endian bug, the porting only took a few hours and
 its now running live keeping my walnut trees in good shape and ensuring a
 steady supply of vegetables to my kitchen

 Over this time it has not so much been designed as evolved as new
 requirements were determined, problems arose that had to be solved (like
 frost damage that caused the loss of 35 walnut trees out of 200 hence a
 frost protect mode).

 In its current guise, it can run 32 zones, 22 of which are used at present
 with 2 used to control pumps. It uses AJAX methods to build a GUI on a web
 browser with JSON objects going back and forth updating the display and
 providing program data to the main engine. All of the UI is 'soft' in that
 it is independent of the server code, a configuration file and the
 html/javascript determine what it looks like.

 A few months ago I made a git repository of the project and a few days ago
 I uploaded it along side a few of my other projects on github. You can
 find it at:
https://github.com/g8ecj/irrigate

 I'm hoping it will inspire others to look at mongoose as more than just
 another web server, to owfs as a means to talking to the real world and
 the power we have from projects like OpenWrt that allow us to use such
 good hardware thats really cheap :)

Re: [Owfs-developers] Problem with 1-Wire USB Adapter

2013-09-27 Thread Gregg Levine

Hello!
This comes up from time to time, Colin. Look at your distribution's
methods of loading modules. It should contain a set of files for
blacklisting modules. On mine I have the IPv6 one blacklisted because
my DSL device is, ah, too old.

Put in your blacklist one where your system possibly put others, put
there the one for w1.

 I've really only set up python to read
 a default owfs installation directory. Never had misreads with
 ds9490. Have noticed sensors appearing and reappearing on the 2483. I
 don't need to poll that often, so if I can code around it
 asynchronously with error correction I'm into that.
 Sure, just read again on error when you have the time to do it. When you
 don't rely on continuous scanning, that should be a no-issue. Same for
 polling temperature values, as they don't change that fast.

 Kind regards

 I notice my DS18S20 and DS18B20 sensors, if there's a network failure or..

 wires onto the leads, reports 85 as the temperature.

 As far as I can tell the crc8 value is correct in these instances.

 a) why does it do this?
 b) this really is not a helpful number. if it was -999 then I could say, ah 
 that's an error value but 85 is a reasonable temperature for the stuff I'm 
 doing
 c) is there any way to tell that this is an error 85 as opposed to the sensor 
 actually being at 85°C ?

 Many thanks.

Hello!
I see. The DSI one is for displays similar to what the majority of
desktops wear, and laptops always wear. The CSI one is for the camera.
It just came out. I do not know how many are being used right now. The
DSI one however has one huge sticking point, the panels for it are too
DELETED! expensive. Most people who own the devices are either
connected to it via the regular HDMI connection, or via networking and
the SSH method. Or (still in my case) via the SDTV connection via a
RCA connection.

The one who posed for that photo of yours must have been special, as
its connectors are different then mine, and mine is a regular, that
is, unmodified B model.

 You can pass --debug option ot owfs but I think you are using the -u
 wrong. You probably have an usb-serial-1-wire adapter. The FT232 should
 show as a serial port /dev/ttyUSB0 or 1 etc.
 So try
 sudo owfs -d /dev/ttyUSB0 -m /weather/1wire

 If you are using Raspi make sure you have the latest kernel (run sudo
 rpi-update) because older usb drivers perform poorly especially with
 serial2usb devices like FT232.

Hello!
Correct. That command is essential to the device to update itself. I
have one such device, and yesterday I did have it working with my
one-wire devices. It took two tries, but getting it to present what I
am used to inside the mnt directory worked.

Now the question is one of, what sort of debugging information did you
want to see from your setup, and on the Raspi?

[Owfs-developers] Raspberry PI and OWFS

2013-05-20 Thread Gregg Levine

Hello!
I've had one of these amazing devices since the end of last year.
However this is my first real chance to try and get something running
on it, and doing something, since the beginning of the year.

So earlier I put on the latest release of the kit available from the
repositories for the thing. And after the usual efforts to get it to
work seeing my DS9097U connected via an FTDI based adapter, I now see
the file-system it creates present in the chosen directory.

The chosen device for all of this will be a DS2406.
-
Is there an easy method for bringing up the webserver for everything
on the Raspberry Pi?

Remember this is all an experimental process so ideally I'm not
planning doing anything special.

Hello!
Peter, try this: Open a terminal window and then enter that string
command. It should enter you into an elevated, read root shell. Then
ask the system about those modules. Ideally those other packages are
needed for managing the FUSE system, the ones that end on -dev are
used if you plan on rebuilding the entire OWFS system from source
code.

The utility one is used for the obvious, managing the whole business.

If that doesn't work you might need to reinstall everything.

 Hi,

 I have many DS18X20 temperature sensors, plus a couple of DS2406

 sensors where the directory shows but when I open it it is empty.  There
 are 7 sensors on this channel, the other 4 are fine.

 I have looked in the statistics/errors directory, all the files read
 zero except for NET_connection_errors which is 1, also in
 uncached/statistics/errors I see the same.

 Any idea what could cause this?  Is there anything I can do to fault
 find further?

 Thanks

Hello!
Mick, isn't this an ongoing issue? I mean it first came up several
versions earlier. As for what is causing this, check your loading. And
is the hub powered directly? Or parasitic powered? Same with the temp
sensors.

Hello!
No problem here.
I'm just still annoyed at the firm that they didn't bother to properly
inform us, (the users) of the circumstances behind why they dropped
the chip. And more importantly why they didn't supply replacements for
it.

 Hello to everyone!

 I'm new to 1-Wire, worked only with ds18b20 for now.
 Recently, I have bought some DS2890 to create some useful modules,
 but surprisingly discovered, that there are no datasheets for these
 chips in DIP8 package.

 I bought them on alibaba site, they look quite factory-build. But I
 have no idea how to use them. Have you ever worked with such?

 Picture:

 http://medvedko.dyndns.info/2890.jpg

 Any advice would be appreciated!


Hello!
I suspect that those are, ah, counterfeit. The datasheet does not
indicate DIP8 designs. They only came in TSOC6 (which is a surface
mounted package.) and TO-92.

Which is strange because the markings on the one you show look
surprisingly close to any of the ones I have here, which are all in
the TO-92 package.

Sorry.

For the TSOC6 package I did a long campaign with Dallas Semiconductor
to go ahead and create them in a rarely used DIP6 package, rarely used
because it was only used in the industry for one specific device and
not directly in the field.

They told me that it would too expensive to do so, and especially for
only one customer. I pointed out that many people would be interested
in them, especially hobbyists who didn't have access to the tools for
using the surface mountable packaging.

No takers.

In fact the part number isn't available. And the replacements don't

 try:
 sfile = open('device_directory')
 val = sfile.read()
 except:
 log the exception details

 The exceptions that I see are 'No such file or directory', but on the
 next cycle it could well read that device again.  I don't get many for the
 I/O boards but temperature sensors I am seeing around 20% failure.
 Everything is on the floor in the study, so there are no excessive cable
 lengths, all devices are powered.

 I will continue to investigate but any suggestions, ideas or theories
 would be most welcome:)

Hello!
It has one. Two in fact. There is a weak pullup inside the chip, (take
a look at the documentation still on file at the website for Maxim.)
And the switch chip has embedded resistance inside it that migrates
towards VCC when the switch has its settings changed. That embedded
resistance is caused by the MOSFETs used in making the product.

Ideally further analysis and support suggests that there should be one
of 100 ohms to 1M presents, but then again I'll need to work on it.

 aie aie aie... I'm restarting a complex problem out of my knowledge
 After trying getting OWFS working on my synology and now on my sheeva I
 wonder how to manage finnaly...

 Any idea of good serial-usb stable adapter I can buy ?

 Le 6/11/2012 23:22, Paul Alfille a écrit :

 I was worried that a serial mode bug had crept into the program, so I just
 tested the current owfs version with a pl2303 and serial adapter on x-64
 architecture (i.e. a desktop system). It works perfectly, both for the
 DS9097U and the passive adapter.

 So assuming your USB/serial adpter and DS9097U are fine, the problem is with
 the two different architectures. Could there be bugs in the ARM version of
 the pl2303 kernel module?

 I'm not exactly how to procede, except that maybe trying another program
 (like digitemp) for comparison might be illuminating.

 I briefly had owfs setup on my router (owfs 2.8p4 using backfire and the

 I can hook up my 1wire-bus to my router tomorrow and test again if it
 helps. Just let me know.

  So do you get different results on your PC and openWRT?

Hello!
Paul, group. did anyone check the release notes for openWRT? The site
will tell us if the host processor is a big ended one or a little
ended one. You'd be surprised how many times people make those
mistakes.

Incidentally Paul, check your time of day read out on your computer.

 I should point out that the raspbian package installs in different locations

 It makes upgrading from the package to a compiled version not completely
 straight forward.  Not sure why, but it would be nice if they installed in
 the same locations.

 Subject: [Owfs-developers] Raspberry pi running Raspbian and owfs

 Hello,

 This simple message, just to say that owfs is running fine on Raspbian.
 I have read many posts here about the Raspberry pi but none saying this
 simple
 thing:
 Raspberry pi + Raspbian + owfs run directly out of the box:
 sudo apt-get install owfs  # to install it
 then edit /etc/owfs.conf to your needs.
 That's all, it works!
 The owfs package contains the version 2.8p15
 I use owfs from 5 years now and I'm planning to move my home 1wire network
 which
 is driving my central heating, on the Raspberry pi.
 Just the script /etc/init.d/owfs is missing only owserver, owhttpd, owftpd
 are
 included and these 3 services started at boot. But it's easy to build this
 script by copying one of these 3. Now when I boot the 4 services are
 started.

 Again thanks Paul and all the community for this fantastic software.

Hello!
Bruce that's how the package was built. Every time I build one for my
Slackware on X86 system, that's how I instruct the scripts to place
everything, into the /usr file system. It makes things easier to
manage.

 On the image on your link, the wires are twisted ... but you say they are
 not. Can you send us another image of your cable?

 I have posted a picture but it needs moderator approval before it will appear.

 I saw that Cat5e ethernet cable is good for 1-wire so I bought 50m of

 not contain 4 twisted pairs, which I believe it should, but 8 separate
 wires.  Am I correct in thinking that it is therefore not Cat5e?

Hello!
Is it anything like the original? Then what you have is a spool of
original CAT5 stuff. I have several feet of it, some of it is wired to
connectors, or ordinary short pieces.

It'll work for either regular Ethernet runs (CAT5 styled) or even
One-Wire applications or for just anything requiring those colors.
