This project consists of a D-Bus API to Phidgets devices.

• "phidgets-manager" : publishes the signals "Attached", "Detached", "Error" and "Devices" on path "/Device"

• "phidgets-ifk" : publishes the signals "Din", "Dout", "Ain" and "Error" on path "/Device"

• "phidgets-sensors" : publishes the signal "State" which reflects the current state of an input. This application must be configured through "sensors.config" file located in "~/.phidgets-dbus" directory.

• "phidgets-couchdb" : records event from "phidgets-ifk" to a local couchdb database

"phidgets-ifk" requires "phidgets-manager" to be running: it subscribes to the "Devices" signal in order to be notified of new "InterfaceKit" devices to service.

Signals are emitted through the interface "com.phidgets.Phidgets".

• Path: /Device

  • Member: Attached
    • sig: "a{sv}"

• Path: /Device

  • Member: Detached
    • sig: "a{sv}"

• Path: /Device

  • Member: Error
    • sig: "a{sv}"

• Path: /Device

  • Member: Devices ## discovered devices, repeating interval
    • sig: "aa{sv}"

• Path: /Device

  • Member: Din (Digital Input Changed event)
    • sig: "sii" (serial, pin#, value)

• Path: /Device

  • Member: Dout (Digital Output Changed event)
    • sig: "sii" (serial, pin#, value)

• Path: /Device

  • Member: AIN (Analog Input Changed event)
    • sig: "sii" (serial, pin#, value)

Signals emitted through the interface "org.sensors":

• Path: /State
  • Member: /State
    • sig: "ssv" (device_id, sensor_name, sensor_state) OR
    • sig: "ssv" (device_id, pin_id, sensor_state)

Example "sensors.config" file (YAML syntax):

Devices:

 ## Device unique id i.e. serial
 80860:
  pins:
   3: porte_fournaise
   4: porte_escalier
   0: porte_garage_1
   1: porte_garage_2

States:
 porte_escalier:
  0: Open
  1: Closed
 porte_garage_1:
  0: Open
  1: Closed
 porte_garage_2:
  0: Open
  1: Closed
 porte_fournaise:
  0: Open
  1: Closed

There are 2 methods:

1. Use the Ubuntu Debian repository jldupont with the package "phidgets-dbus"

2. Use the "Download Source" function of this git repo and use "sudo make install"

• DBus python bindings
• Phidgets Library (available in the PPA)
• Python Phidgets Library (available in the PPA)

There is an issue with releases of Phidgets' Python module. Please see this thread to help resolve it.

• v1.2:

  • added check for Phidgets library (desktop notification popup if not found)
  • added 'phidgets-couchdb' application

• v1.3: just changed polling interval for IFK down to 1 second

• v1.4: phidgets-sensors: now also outputs signal if no configuration for a pin is present e.g. "din: $pin"
