|
|
* Revision 1.3 2001/01/29 14:03:56 bradleyb
|
|
* Fixed build, minor fixes
|
|
*
|
|
* Revision 1.2 2001/01/24 04:29:45 bradleyb
|
|
* changed args_find to FindArg
|
|
*
|
|
* Revision 1.1.1.2 2001/01/19 03:33:52 bradleyb

* Import of d2x-0.0.9-pre1
|
|
*
|
|
* Revision 1.1.1.1 1999/06/14 21:58:26 donut
|
|
* Import of d1x 1.37 source.
|
|
*
|
|
* Revision 1.37 1995/10/07 13:22:31 john
|
|
* Added new method of reading joystick that allows higher-priority
|
|
* interrupts to go off.
|
|
*
|
|
* Revision 1.36 1995/03/30 11:03:40 john
|
|
* Made -JoyBios read buttons using BIOS.
|
|
*
|
|
* Revision 1.35 1995/02/14 11:39:25 john

|
* Added polled/bios joystick readers..
|
|
*
|
|
* Revision 1.34 1995/02/10 17:06:12 john

|
|
*
|
|
* Revision 1.33 1995/01/27 16:39:42 john
|
|
* Made so that if no joystick detected, it wont't
|
|
* read buttons.
|
|
*
|
|
* Revision 1.32 1995/01/12 13:16:40 john
|
|
* Made it so that joystick can't lose an axis
|
|
* by 1 weird reading. Reading has to occurr during
|
|
* calibration for this to happen.
|
|
*
|
|
* Revision 1.31 1994/12/28 15:56:03 john
|
|
* Fixed bug that refused to read joysticks whose
|
|
* min,cen,max were less than 100 apart.
|
|
*
|
|
* Revision 1.30 1994/12/28 15:31:53 john
|
|
* Added code to read joystick axis not all at one time.
|
|
*
|
|
* Revision 1.29 1994/12/27 15:44:36 john
|
|
* Made the joystick timeout be at 1/100th of a second,
|
|
* regardless of CPU speed.
|
|
*
|
|
* Revision 1.28 1994/12/04 11:54:54 john
|
|
* Made stick read at whatever rate the clock is at, not
|
|
* at 18.2 times/second.
|
|
*
|
|
* Revision 1.27 1994/11/29 02:25:40 john
|
|
* Made it so that the scaled reading returns 0
|
|
* if the calibration factors look funny..
|
|
*
|
|
* Revision 1.26 1994/11/22 11:08:07 john
|
|
* Commented out the ARCADE joystick.
|
|
*
|
|
* Revision 1.25 1994/11/14 19:40:26 john
|
|
* Fixed bug with no joystick being detected.

* Took out the calibration in joy_init
|
|
*
|
|
* Revision 1.22 1994/10/17 10:09:57 john

|
* Made the state look at last_State, so that a joy_flush
|
|
* doesn't cause a new down state to be added next reading.
|
|
*
|
|
* Revision 1.21 1994/10/13 11:36:23 john
|
|
* Made joy_down_time be kept track of in fixed seconds,
|
|
* not ticks.
|
|
*
|
|
* Revision 1.20 1994/10/12 16:58:50 john
|
|
* Fixed bug w/ previous comment.
