**CIGAL Reference Manual, Chapter 7 (Hardware): Gaming Device Interface**

=====GAMEPORT - Gaming device I/O interface=====

 **usage: init gameport [Devnum ButtonsperAxis Naxes DigRevPol AlogRevPol]**

The GAMEPORT software interface in CIGAL is used for any "gaming device", regardless of whether it is connected via the traditional 15-pin "game-port" hardware connection or via a USB cable.

Device initialization options for the [[jvs:cigal:manual:chapter2:init|init]] gameport command are:

  * DEVNUM -- Gaming device number 0,1,2,3,... (default = 0)
  * ButtonsPerAxis -- Number of buttons per device axis (default = 4)
  * NAxes -- Number of device axes (default = 2).
  * DigRevPol -- Digital reverse polarity flag.
  * AlogRevPol -- Analog reverse polarity flag. If AlogRevPol != 0, input a/d values will be:
           inputval = alogrevpol - valuefromdevice

**Hardware installation**

Plug your device into either the 15-pin game-port connection or any USB port.

**CIGAL configuration**

In order for CIGAL to use this device it must be told to look for it via its **init gameport** command. Usually that is done by using the CIGAL [[jvs:cigal:manual:chapter1:configure|Configure(1)]] program to put the appropriate [[biac:jvs:cigal:manual:chapter2:init|Init(2)]] command into the automatic [[biac:jvs:cigal:manual:chapter1:startup|start-up]] scripts. To do so, simply start CIGAL, enter the **configure** command, and click yes when asked if you have a gaming device.  (Alternatively you could simply edit your **userconfig.imp** or **sysconfig.imp** file if it already exists and manually change the commands in the initialize section.)

**Testing the device**
