It seems my USB adapter causes OWFS to crash randomly. It seems to work for a while and then cause a crash.

OWFS[2625]: DEFAULT: ow_ds9490.c:(250) Unclear what <> means in USB specification, will use first adapter.
OWFS[2625]: DEFAULT: ow_usb_msg.c:(295) Opened USB DS9490 bus master at 1:7.
OWFS[2625]: DEFAULT: ow_usb_cycle.c:(191) Set DS9490 1:7 unique id to 81 47 D5 30 00 00 00 9E

I also am trying out the new barometer and the pressure does not seem to be reading properly. Many of the identifiers below show -1 or something similar.

    Sorry this is 2.9p7

    Let me test and find the problem. The crash may be due to a new aggressive mutext testing that was put in.

      The problem with owfs is a newly discovered (and fixed) bug. It'll be part
      of 2.9p8 soon.

      One of the patches incorporated caused an (intentional) crash if a mutex
      was freed twice. It did discover a longstanding bug in owfs (filesystem)
      but was a little rude to push out in a release.

      As for the Hobbybaords barometer, I supported it from the datasheet, not
      the actual device, so feedback would be very welcome.

      In the snippet of debug output you show, the locator and r_locator results
      is expected.
      I'm confused by:
      /EF.CB4C20150000/barometer/: altitude,config,location,
      polling_available,polling_frequency,pressure,pressure_altitude,reboot,reset,
      temperature

      That should be a subdirectory with data for those properties. Were the
      values all -1?

    Paul,

    When I go in an cat /altitude for example I get back:

    i,000000,000001,rw,000012,v,

    I don't think this is what I should expect.

     

  • Paul Alfille

    Paul Alfille - 2014-10-14

    That looks like the "structure" directory entry -- is shows that altitude is an integer, scalar, read-write, volatile, etc.

    Are you sure you were reading /EF.1234123412344/barometer/altitude and not /structure/EF/barometer/altutude ? (or whatever your device number is?

    Thanks,

    Paul

    Paul,

    owfs is really erratic, I can't reliably access the devices. I have to reboot to get the devices to show in the root of the mount point. Rebooted and logged into the new barometer and trying to list, it gives me the following error:

    root@silver:/mnt/1wire/EF.CB4C20150000# ls
    ls: reading directory .: File too large

    At the same time I can use Python to list the following:

    _usePath: /EF.CB4C20150000
    _type: HobbyBoards_EF
    _path: /EF.CB4C20150000
    _useCache: True
    /EF.CB4C20150000/barometer/: altitude,config,location,polling_available,polling_frequency,pressure,pressure_altitude,reboot,reset,temperature
    /EF.CB4C20150000/family: EF
    /EF.CB4C20150000/locator: FFFFFFFFFFFFFFFF
    /EF.CB4C20150000/type: HobbyBoards_EF
    /EF.CB4C20150000/crc8: 5D
    /EF.CB4C20150000/version: 1.0
    /EF.CB4C20150000/r_id: 000015204CCB
    /EF.CB4C20150000/address: EFCB4C201500005D
    /EF.CB4C20150000/r_address: 5D000015204CCBEF
    /EF.CB4C20150000/type_number: 6
    /EF.CB4C20150000/r_locator: FFFFFFFFFFFFFFFF
    /EF.CB4C20150000/id: CB4C20150000

    As I write this and go back to the mount point all I have is the following:

    root@silver:/mnt/1wire# ls
    bus.0 settings statistics structure system uncached

    All I see in the logs is the USB issue (which you commented above), does this have anything to do with this issue?

    I have been messing with this sensor more and realize that owfs process frequently can't access the /barometer directory:

    silver:/mnt/1wire/EF.CB4C20150000# ls
    address alias crc8 family id locator r_address r_id r_locator type type_number version

    I can see it exists via owserver and python:

    /EF.CB4C20150000/barometer/: altitude,config,location,polling_available,polling_frequency,pressure,pressure_altitude,reboot,reset,temperature
    /EF.CB4C20150000/family: EF
    /EF.CB4C20150000/locator: FFFFFFFFFFFFFFFF
    /EF.CB4C20150000/type: HobbyBoards_EF
    /EF.CB4C20150000/crc8: 5D
    /EF.CB4C20150000/version: 1.0
    /EF.CB4C20150000/r_id: 000015204CCB
    /EF.CB4C20150000/address: EFCB4C201500005D
    /EF.CB4C20150000/r_address: 5D000015204CCBEF
    /EF.CB4C20150000/type_number: 6
    /EF.CB4C20150000/r_locator: FFFFFFFFFFFFFFFF
    /EF.CB4C20150000/id: CB4C20150000

    I did run debug on owfs and I am able to enter the barometer directory even though it does not show up in owfs.

    The current pressure is 29.90 and its 71 so I don't see anything matching up.

    Hi, I just wondered if there been any resolution on this new HB barometer with owfs/owserver?
    I have recently bought one of these barometers as the old one died.
    I am currently using OWW (written in C by Dr Simon Melhuish) on Ubuntu Server 14.10 but wish to try and get the weather station running with owserver and python.
    This is the output I seem to be getting with owhttpd:

    address EF307520150000A0
    alias
    crc8 A0
    family EF
    id 307520150000
    locator FFFFFFFFFFFFFFFF
    r_address A0000015207530EF
    r_id 000015207530
    r_locator FFFFFFFFFFFFFFFF
    type HobbyBoards_EF
    type_number 6
    version 01.0A

    Also I cannot seem to get any directory structure of the devices in /mnt/1wire either even though the owfs.conf file appears to be correct:-

    # Sample configuration file for the OWFS suite for Debian GNU/Linux.
#
#
# This is the main OWFS configuration file. You should read the
# owfs.conf(5) manual page in order to understand the options listed
# here.

######################## SOURCES ########################
#
# With this setup, any client (but owserver) uses owserver on the
# local machine...
! server: server = localhost:4304
#
# ...and owserver uses the real hardware, by default fake devices
# This part must be changed on real installation
# server: FAKE = DS18S20,DS2405
#
# USB device: DS9490
#server: usb = all
#
# Serial port: DS9097
server: device = /dev/ttyS0
#
# owserver tcp address
server: server = 192.168.1.165:3131
#
# random simulated device
#server: FAKE = DS18S20,DS2405
#
######################### OWFS ##########################
#
mountpoint = /mnt/1wire
allow_other
#
####################### OWHTTPD #########################

http: port = 2121

####################### OWFTPD ##########################

ftp: port = 2120

####################### OWSERVER ########################

server: port = localhost:4304

    I would be grateful for any assistance and if any assistance is required for this barometer, I will be happy to oblige,

    David
