Roberto Spadim — 2012-05-23T23:14:01

hi guys...
i was using some android tablets to develop some web sites
now i started some development at windows ce with .net framework

does anyone know if we can port owfs to .net? or maybe windows ce plataform?
just serial (usb-serial converters + ds2480b), rfc2217 and owserver bus
masters

Re: Release 2.8p15

Paul Alfille — 2012-05-23T11:11:05

Let me answer the easy ones:



http://nn.nn.nn.nn:3001/bus.0/uncached and http://nn.nn.nn.nn:3001/uncached
/bus.0 <http://nn.nn.nn.nn:3001/uncached%20/bus.0> and for that matter,
http://nn.nn.nn.nn:3001/bus.0/uncached/bus.0 ?


The order of "uncached" doesn't matter (technically is should be first but
the parsing logic is flexible since there is no ambiguity. It can't be a
device property, however, like 10.234234234/uncached )

The second question, /bus.0/bus.0 has to be a bus on an owserver. It is
never equivalent to just /bus.0

Re: Hobby board LCD driver cannot write to lcdand simultaneously read the PIO

Guy — 2012-05-23T10:17:03


Yes Patryk, thanks again, the datasheet is clear:
When configured as RST, a LOW input sets all PIO outputs to the "off" state by
setting all bits in the PIO Output Latch State Register.
Just what I needed a full reset. My script is now perfectly working.
That's great

hi guys, anyone here use plc sdcd or another control hardware?

Re: Release 2.8p15

brucek — 2012-05-22T20:47:07

So far p15 seems much more stable (using an USB master)

But, I still can not change units in owhttpd

http://nn.nn.nn.nn:3001/settings/units?temperature_scale=f still returns the
unit as 'C'.

 

Also, what, if anything is different between
http://nn.nn.nn.nn:3001/bus.0/uncached and http://nn.nn.nn.nn:3001/uncached
<http://nn.nn.nn.nn:3001/uncached%20/bus.0>  /bus.0 and for that matter,
http://nn.nn.nn.nn:3001/bus.0/uncached/bus.0 ?

 

Thanks for the good work

Re: problems with writing data

Paul Alfille — 2012-05-22T17:07:53

Hi Arkhipenka,

If understand your findings, you've found that you get different results on
sparc64 and i386.

I assume that you're using linux rather than openSolaris (or whatever it's
called now).

There are 3 different parts here. Fuse, owfs and libusb. All might be
problematic on a different architecture.

Can we try eliminating fuse for the time being with either owhttpd or
owserver/owwrite ?

problems with writing data

Arkhipenka Stanislau — 2012-05-22T16:43:57

Hello.
Could you, please, help me to solve a problem:
im trying to use owfs on SPARC64 achitecture.
Im using debian squeeze. I compiled owfs from sources owfs-2.5p15:
./configure --enable-debian  --enable-usb
make
make install 

(also tried ./configure --build=sparc64-linux target=sparc64-linux --enable-
debian --enable-usb)
Im starting owfs server by command:
/opt/owfs/bin/owfs -u --allow_other -m 1wire --error_level=0 --
mountpoint="/mnt/1wire"
and it starts sucsessfuly, but when im trying to write data "echo 1 > 
/mnt/1wire/12.4A7A80000000/PIO.A". there r no resoults from my actions.
i mean when after this im doing cat /mnt/1wire/12.4A7A80000000/PIO.A i resive 
0.
I tried to do the same actions on amd64 and on i386 and it works fine. 
I tried to set --error_level=5 and then compare loges from SPARC64 and amd64 - 
they turned the same (i mean that pid, machine name and adresses are different, 
but the other information is the same).

P.S. im using DS9490R

sorry for my english.

the DS9490 are working fine.

P.S.: libow is getting bigger and bigger which gets to a problem on thin
boxes with 4MB Flash where ~200-400k are left for such things, would it
make sense to introduce configure/compile-time switches to exclude "big"
libs (top 3 currently ow_2760.o, ow_bae.o, ow_eds.o) on demand(?)
I'd offer to provide a patch ;)
Not to say I dislike any of these, I i.e. love the BAE! But the payload
seems heavy and 99,9% here are just DS1820 and DS2438..

Okay, yes, that makes sense. I'll see what I can come up with in terms 
of an Ubuntu Upstart script. The one I have right now definitely does 
not work because of the synchronization problem we're discussing.


Definitely another option. Perhaps add configuration options to the 
clients so they don't fail/quit when they cannot contact owserver and 
instead attempt a connection every X seconds?

Cheers,

Eloy Paris.-

Re: Release 2.8p15

Paul Alfille — 2012-05-21T20:36:09

You summarized the problem well. Synchronizing the start of owserver and
it's clients can be problematic.

As for suspending the boot process -- the whole scheme can be done in the
background.

I.e run this script in the background:

#!/bin/sh
# script to start the 1-wire processes
# with delay for owserver

# owserver address
address=""
/opt/owfs/bin/owserver --fake=10 -p $address

# wait for owserver to accept connections:
e="1"
while [ $e -ne 0 ] ; do
  /opt/owfs/bin/owexist -q $address
  e=$?
  sleep 1
done

/opt/owfs/bin/owhttpd -s $address -p 4444
/opt/owfs/bin/owfs      -s $address -m /mnt/1wire --allow_other

---------------------------------

I guess another approach would be to allow owhttpd and owfs to function
even if they can't yet connect to owserver.

Can someone summarize what this problem is?

I know that in my case owserver takes a while to start. It sounds like 
the same problem as "late-starting owservers" but I cannot seem to find 
the February 1st report that Klas mentions.

Based on Paul's comment below, I take it that the problem has been 
identified and will be fixed in the next release?

This has been a problem for me because my owfs start script cannot 
execute owserver and owfs in succession because owserver goes daemon 
immediately but does not really start servicing requests, and then owfs 
fails to find a working owserver and then quits. So, after each reboot I 
need to run owfs manually. Fortunately I don't restart my server often.

I'll look into that owexist trick that Paul mentions, though it does not 
seem to be perfect because it would suspend the boot process for a 
little bit.

Cheers,

Eloy Paris.-

yes, and with latest v9 bae0910 firmware a new adc configuration bit allows
to sample at 10bit and an adc10 property have been added.
Previous bae0910 firmwares are still supported with 2.8p15

v9 firmware is here

Re: Release 2.8p15

Paul Alfille — 2012-05-21T16:03:05

Good news and bad news on the late-starting owservers

There is a new command: owexist
It needs an update (even from the latest release) to
module/owshell/src/c/owexist.c
but you can then run:

address="";e="1"; while [ $e -ne 0 ] ; do /opt/owfs/bin/owexist -q $address
; e=$? ; sleep 1 ; done

Which will loop until owserver appears.
address="" for default owserver localhost:4304 address

You can also wait for the next release, which shouldn't be as long a wait.

Hmm, I didn't got it:

Did you tested your Bus.1 and Bus.2 which one is the old DS2482-100 and
which is the new DS2483?
And, more important question: Are there 1-Wire devices connected to the
DS2483 working with OWFS??
