USB JOYSTICK INTERFACE DATA SHEET Pt. No. 909999-A Drawn: K. Meneely 16/2/06 The Apem Components USB Joystick Interface is designed to connect a Joystick with up-to 3 axes and 8 buttons to a USB port on a PC or Mac. We have utilised a 'JoyWarrior' controller chip from Code Mercenaries for controlling the USB interface. The interface is Fully USB V1.1/2.0 and HID 1.1 compliant. It is compatible with standard system drivers, so no special drivers are required. There are 3 analog inputs for X, Y and Z axes with 10 bit resolution and connections for up-to 8 pushbuttons. The interface board measurements and mounting points are shown below: 8.5 33 Pin 1 6 off 3.5 dia holes 3 25 44 50 CONN2 3 Pin 1 CONN1 44 50 USB connection is made via a 5 way Molex KK style header on the board. A Suitable USB cable (1.5m long) is also available - Part number 919998. The joystick connects to Conn1, a 14 way molex KK style header.

Any operating system with support for USB HID game controllers will have the necessary drivers already in place. Operation with Windows Any Windows versions 98 and newer and 2000 and newer will work with JoyWarrior. Older versions of Windows do not support USB. Upon connecting a JoyWarrior based device for the first time you will be asked to perform the standard driver install. The same happens if you connect the device to a different USB port on the same computer. After the driver installation has completed you should be able to see the device in the "Game Controllers" control panel and be able to access it via DirectInput. Operation with MacOS MacOS 9.0 and up and MacOS X do support JoyWarrior direct. Some versions of MacOS 8.x do support USB as well, though their use is not recommended. With MacOS 9.x you will be able to use JoyWarrior based devices via InputSprocket or with 3rd party software like USB Overdrive. On MacOS X access is available via the HIDManager. There will be no warnings or dialogs when a properly functioning JoyWarrior based device is connected under MacOS, it will simply start to work. V 1.0.3, July 25th 2005 for Chip Revision V1.0.3.x Remote Wakeup All JoyWarrior chips support the remote wakeup feature. They are able to wake the host computer from sleep state if the host operating system does enable this feature. Remote wakeup is initiated by JoyWarrior if any button is pressed or if any switch of the direction pad closes. Changes on the analog axes are not detected. For remote wakeup to be functional on the JoyWarrior20 chips the RC combination on the CExt pin as specified in the application circuits is required. When remote wakeup is active and the USB is in suspend state JoyWarrior20 will wake periodically and check if any switches are closed, if not it will immediately return to suspend mode. Joystick axis orientation USB specifies the axis orientation as follows: For the X axis values should increase for left to right movement, Y axis values increase for far to near movements (i.e. pulling the stick gets you larger values), Z axis values should increase for high to low movement. Non Joystick Applications USB does allow a Human Interface Device controller to very detailed specify the function of axes and buttons. This gives a game controller device the option to specify a certain axis to be a throttle or break or something else. The standard JoyWarrior chips are for general use, so the analog axes variants just specify X, Y, Z and the switch inputs are defined as being just buttons. DC Characteristics Parameter Vcc Icc Isb Iol Rup Vith Voh Vol Vdi Vcm Vse Cin Iio Rpu Rpd Min Operating Voltage Operating Supply Current Suspend mode current Sink current on output pins Pull-up Resistance Input Threshold Voltage USB Interface Static output high Static output low Differential Input sensitivity Differential Input common Mode Range Single Ended Transceiver Threshold Transceiver capacitance Hi-Z State Data Line Leakage Bus Pull-up resistance Bus Pull-down resTstance 4.35 8 8 45% 2.8 0.2 0.8 0.8 -10 7.35 * 14.25 Max Units 5.25 25 20 24 24 65% V mA ?A mA k?

Please refer to the Virtual Projects Website http://www.vpsoft.com/software/joymouse.php for details on their 'Joymouse' software. JoyMouse is the utility program which makes any standard joystick act like a mouse device. It means when you move joystick axis mouse pointer starts to move in the same direction. Pointer speed depends on the joystick's position. Joystick buttons by default are mapped to Left click, Right Click, Double Click and Alternative Speed, but you can easily change all the mappings. As an additional functionality, pointer can wrap through the display edges, go in reverse and gain some latency amount. Application is just perfect suit for: Browsing the web Playing the games which originally does not support joystick Using instead of a mouse, if you don't like the mouse, or cannot use it for some reasons Many other excited things to do when you're at your computer System requirements: 1) MS Windows 95, 98, ME, NT, 2000 or XP 2) 4Mb of free hard drive space 3) Microsoft compatible Joystick (optional) Key features: Complete mouse device replacement using joystick or keyboad! Customiseable joystick button mappings Configuration wizard Possibility to invert mouse axes Possibility to add latency (filter) to the pointer movement Adjustable pointer speed Possibility to make mouse pointer wrappable through the screen edges
