Build-In 1Wire does not work!

  • K

    Hi all,

    I have a Neuron M103 which has USB and a 1-wire interface.

    When I connect my sensors to the build-in port I do not find them. Connecting through a USB adapter works flawlessly!

    Any idea?
    I changed /etc/owfs.conf according to the device I am using. Disabled the FAKE device and tried to enable the i2c:

    #server: FAKE = DS18S20,DS2405

# Setting for Neuron M103 
server: device = /dev/i2c-1
#
# USB device: DS9490
#server: usb = all

    Now when I do i2cdetect -l I get the correct one I used in above owfs.conf:

    i2c-1   i2c             bcm2835 I2C adapter                     I2C adapter

    Seems to be the bus is recognized properly:

    root@zentrale:/heizung/src# i2cdetect -y 1
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- 18 -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- UU -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- UU
70: -- -- -- -- -- -- -- --

    Changing the device to i2c-1 in owfs.conf, restarting owfs and switching cable to Neuron port I do not get any device:

    root@zentrale:/heizung/src# owdir
/bus.0
/uncached
/settings
/system
/statistics
/structure
/simultaneous
/alarm

    Switching everything back to USB I get proper information:

    root@zentrale:/heizung/src# owdir

    Any idea how to use the build-in i2c-1-wire-bus?
