Phidget InterfaceKit driver.

The phidgetIFK driver communicates with the all the Phidget Interface Kits: IFK 8/8/8 , IFK 0/16/16 , Circular and Linear Touch IFKs, and LCD IFK. The ammount of digital and analog inputs is adjusted automatically for each device (queried after the initial connection).

Compile-time dependencies

• none

Provides

• aio
• dio
• speech

Requires

• libphidget from www.phidgets.com should be installed.

Configuration requests

• none

Configuration file options

• serial (integer)
  • Default: -1
  • This defines which phidget will be controlled if there is more than one connected to the USB bus. You can obtain the number with lsusb, like this: "lsusb -v |grep iSerial". The default is -1 , and it will connect to the first phidget available.

• sampling_rate (integer)
  • Default: 20
  • How often (in mS) should the phidget produce data. Reading at 17mS produces data at a rate of ~ 59Hz.

• alarmtime (integer)
  • Default: 25
  • If the data acquisition cycle takes longer than this time (in mS), a warning will be printed.

• provides
  • The driver supports the "speech" interface for printing data to the LCD of the Interface kits that have it.
  • An "aio" interface gives information about the analog sensors connected to the Interface Kit.
  • The "dio" interface controls the digital inputs and outputs present.

Example

driver
(
  name "phidgetIFK"
  provides ["aio:0" "dio:0" "speech:0"]
  #provides ["aio:0" "dio:0"]
  serial -1
  alwayson 1
  samplingrate 17
  alarmtime 21
)
