29 | 1. Intro | |
30 | ~~~~~~~~ | |
31 | The joystick driver for Linux provides support for a variety of joysticks | |
32 | and similar devices. It is based on a larger project aiming to support all | |
33 | input devices in Linux. | |
34 | ||
35 | Should you encounter any problems while using the driver, or joysticks | |
36 | this driver can't make complete use of, I'm very interested in hearing about | |
37 | them. Bug reports and success stories are also welcome. | |
38 | ||
39 | The input project website is at: | |
40 | ||
1da177e4 LT |
41 | http://atrey.karlin.mff.cuni.cz/~vojtech/input/ |
42 | ||
43 | There is also a mailing list for the driver at: | |
44 | ||
45 | listproc@atrey.karlin.mff.cuni.cz | |
46 | ||
47 | send "subscribe linux-joystick Your Name" to subscribe to it. | |
48 | ||
49 | 2. Usage | |
50 | ~~~~~~~~ | |
51 | For basic usage you just choose the right options in kernel config and | |
52 | you should be set. | |
53 | ||
54 | 2.1 inpututils | |
55 | ~~~~~~~~~~~~~~ | |
56 | For testing and other purposes (for example serial devices), a set of | |
57 | utilities is available at the abovementioned website. I suggest you download | |
58 | and install it before going on. | |
59 | ||
60 | 2.2 Device nodes | |
61 | ~~~~~~~~~~~~~~~~ | |
bf6ee0ae | 62 | For applications to be able to use the joysticks, |
1da177e4 LT |
63 | you'll have to manually create these nodes in /dev: |
64 | ||
65 | cd /dev | |
66 | rm js* | |
67 | mkdir input | |
68 | mknod input/js0 c 13 0 | |
69 | mknod input/js1 c 13 1 | |
70 | mknod input/js2 c 13 2 | |
71 | mknod input/js3 c 13 3 | |
72 | ln -s input/js0 js0 | |
73 | ln -s input/js1 js1 | |
74 | ln -s input/js2 js2 | |
75 | ln -s input/js3 js3 | |
76 | ||
77 | For testing with inpututils it's also convenient to create these: | |
78 | ||
79 | mknod input/event0 c 13 64 | |
80 | mknod input/event1 c 13 65 | |
81 | mknod input/event2 c 13 66 | |
82 | mknod input/event3 c 13 67 | |
83 | ||
84 | 2.4 Modules needed | |
85 | ~~~~~~~~~~~~~~~~~~ | |
86 | For all joystick drivers to function, you'll need the userland interface | |
87 | module in kernel, either loaded or compiled in: | |
88 | ||
89 | modprobe joydev | |
90 | ||
91 | For gameport joysticks, you'll have to load the gameport driver as well; | |
92 | ||
93 | modprobe ns558 | |
94 | ||
95 | And for serial port joysticks, you'll need the serial input line | |
96 | discipline module loaded and the inputattach utility started: | |
97 | ||
98 | modprobe serport | |
99 | inputattach -xxx /dev/tts/X & | |
100 | ||
101 | In addition to that, you'll need the joystick driver module itself, most | |
102 | usually you'll have an analog joystick: | |
103 | ||
104 | modprobe analog | |
105 | ||
106 | For automatic module loading, something like this might work - tailor to | |
107 | your needs: | |
108 | ||
109 | alias tty-ldisc-2 serport | |
110 | alias char-major-13 input | |
111 | above input joydev ns558 analog | |
112 | options analog map=gamepad,none,2btn | |
113 | ||
114 | 2.5 Verifying that it works | |
115 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
116 | For testing the joystick driver functionality, there is the jstest | |
117 | program in the utilities package. You run it by typing: | |
118 | ||
119 | jstest /dev/js0 | |
120 | ||
121 | And it should show a line with the joystick values, which update as you | |
122 | move the stick, and press its buttons. The axes should all be zero when the | |
123 | joystick is in the center position. They should not jitter by themselves to | |
124 | other close values, and they also should be steady in any other position of | |
125 | the stick. They should have the full range from -32767 to 32767. If all this | |
126 | is met, then it's all fine, and you can play the games. :) | |
127 | ||
128 | If it's not, then there might be a problem. Try to calibrate the joystick, | |
129 | and if it still doesn't work, read the drivers section of this file, the | |
130 | troubleshooting section, and the FAQ. | |
131 | ||
132 | 2.6. Calibration | |
133 | ~~~~~~~~~~~~~~~~ | |
134 | For most joysticks you won't need any manual calibration, since the | |
135 | joystick should be autocalibrated by the driver automagically. However, with | |
136 | some analog joysticks, that either do not use linear resistors, or if you | |
137 | want better precision, you can use the jscal program | |
138 | ||
139 | jscal -c /dev/js0 | |
140 | ||
141 | included in the joystick package to set better correction coefficients than | |
142 | what the driver would choose itself. | |
143 | ||
144 | After calibrating the joystick you can verify if you like the new | |
145 | calibration using the jstest command, and if you do, you then can save the | |
146 | correction coefficients into a file | |
147 | ||
148 | jscal -p /dev/js0 > /etc/joystick.cal | |
149 | ||
150 | And add a line to your rc script executing that file | |
151 | ||
152 | source /etc/joystick.cal | |
153 | ||
154 | This way, after the next reboot your joystick will remain calibrated. You | |
155 | can also add the jscal -p line to your shutdown script. | |
156 | ||
157 | ||
158 | 3. HW specific driver information | |
159 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
160 | In this section each of the separate hardware specific drivers is described. | |
161 | ||
162 | 3.1 Analog joysticks | |
163 | ~~~~~~~~~~~~~~~~~~~~ | |
164 | The analog.c uses the standard analog inputs of the gameport, and thus | |
165 | supports all standard joysticks and gamepads. It uses a very advanced | |
166 | routine for this, allowing for data precision that can't be found on any | |
167 | other system. | |
168 | ||
169 | It also supports extensions like additional hats and buttons compatible | |
170 | with CH Flightstick Pro, ThrustMaster FCS or 6 and 8 button gamepads. Saitek | |
171 | Cyborg 'digital' joysticks are also supported by this driver, because | |
172 | they're basically souped up CHF sticks. | |
173 | ||
174 | However the only types that can be autodetected are: | |
175 | ||
176 | * 2-axis, 4-button joystick | |
177 | * 3-axis, 4-button joystick | |
178 | * 4-axis, 4-button joystick | |
179 | * Saitek Cyborg 'digital' joysticks | |
180 | ||
181 | For other joystick types (more/less axes, hats, and buttons) support | |
182 | you'll need to specify the types either on the kernel command line or on the | |
183 | module command line, when inserting analog into the kernel. The | |
184 | parameters are: | |
185 | ||
186 | analog.map=<type1>,<type2>,<type3>,.... | |
187 | ||
188 | 'type' is type of the joystick from the table below, defining joysticks | |
189 | present on gameports in the system, starting with gameport0, second 'type' | |
190 | entry defining joystick on gameport1 and so on. | |
191 | ||
192 | Type | Meaning | |
193 | ----------------------------------- | |
194 | none | No analog joystick on that port | |
195 | auto | Autodetect joystick | |
196 | 2btn | 2-button n-axis joystick | |
197 | y-joy | Two 2-button 2-axis joysticks on an Y-cable | |
198 | y-pad | Two 2-button 2-axis gamepads on an Y-cable | |
199 | fcs | Thrustmaster FCS compatible joystick | |
200 | chf | Joystick with a CH Flightstick compatible hat | |
201 | fullchf | CH Flightstick compatible with two hats and 6 buttons | |
202 | gamepad | 4/6-button n-axis gamepad | |
203 | gamepad8 | 8-button 2-axis gamepad | |
204 | ||
205 | In case your joystick doesn't fit in any of the above categories, you can | |
206 | specify the type as a number by combining the bits in the table below. This | |
207 | is not recommended unless you really know what are you doing. It's not | |
208 | dangerous, but not simple either. | |
209 | ||
210 | Bit | Meaning | |
211 | -------------------------- | |
212 | 0 | Axis X1 | |
213 | 1 | Axis Y1 | |
214 | 2 | Axis X2 | |
215 | 3 | Axis Y2 | |
216 | 4 | Button A | |
217 | 5 | Button B | |
218 | 6 | Button C | |
219 | 7 | Button D | |
220 | 8 | CHF Buttons X and Y | |
221 | 9 | CHF Hat 1 | |
222 | 10 | CHF Hat 2 | |
223 | 11 | FCS Hat | |
224 | 12 | Pad Button X | |

230 | 19 | GamePad | |
231 | 20 | Joy2 Axis X1 | |
232 | 21 | Joy2 Axis Y1 | |
233 | 22 | Joy2 Axis X2 | |
234 | 23 | Joy2 Axis Y2 | |
235 | 24 | Joy2 Button A | |
236 | 25 | Joy2 Button B | |
237 | 26 | Joy2 Button C | |
238 | 27 | Joy2 Button D | |
239 | 31 | Joy2 GamePad | |
240 | ||
241 | 3.2 Microsoft SideWinder joysticks | |
242 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
243 | Microsoft 'Digital Overdrive' protocol is supported by the sidewinder.c | |
244 | module. All currently supported joysticks: | |
245 | ||
246 | * Microsoft SideWinder 3D Pro | |
247 | * Microsoft SideWinder Force Feedback Pro | |
248 | * Microsoft SideWinder Force Feedback Wheel | |
249 | * Microsoft SideWinder FreeStyle Pro | |
250 | * Microsoft SideWinder GamePad (up to four, chained) | |
251 | * Microsoft SideWinder Precision Pro | |
252 | * Microsoft SideWinder Precision Pro USB | |
253 | ||
254 | are autodetected, and thus no module parameters are needed. | |
255 | ||
256 | There is one caveat with the 3D Pro. There are 9 buttons reported, | |
257 | although the joystick has only 8. The 9th button is the mode switch on the | |
258 | rear side of the joystick. However, moving it, you'll reset the joystick, | |
259 | and make it unresponsive for about a one third of a second. Furthermore, the | |
260 | joystick will also re-center itself, taking the position it was in during | |
261 | this time as a new center position. Use it if you want, but think first. | |
262 | ||
263 | The SideWinder Standard is not a digital joystick, and thus is supported | |
264 | by the analog driver described above. | |
265 | ||
266 | 3.3 Logitech ADI devices | |
267 | ~~~~~~~~~~~~~~~~~~~~~~~~ | |
268 | Logitech ADI protocol is supported by the adi.c module. It should support | |
269 | any Logitech device using this protocol. This includes, but is not limited | |
270 | to: | |
271 | ||
272 | * Logitech CyberMan 2 | |
273 | * Logitech ThunderPad Digital | |
274 | * Logitech WingMan Extreme Digital | |
275 | * Logitech WingMan Formula | |
276 | * Logitech WingMan Interceptor | |
277 | * Logitech WingMan GamePad | |
278 | * Logitech WingMan GamePad USB | |
279 | * Logitech WingMan GamePad Extreme | |
280 | * Logitech WingMan Extreme Digital 3D | |
281 | ||
282 | ADI devices are autodetected, and the driver supports up to two (any | |
283 | combination of) devices on a single gameport, using an Y-cable or chained | |
284 | together. | |
285 | ||
286 | Logitech WingMan Joystick, Logitech WingMan Attack, Logitech WingMan | |
287 | Extreme and Logitech WingMan ThunderPad are not digital joysticks and are | |
288 | handled by the analog driver described above. Logitech WingMan Warrior and | |
289 | Logitech Magellan are supported by serial drivers described below. Logitech | |
290 | WingMan Force and Logitech WingMan Formula Force are supported by the | |
291 | I-Force driver described below. Logitech CyberMan is not supported yet. | |
292 | ||
293 | 3.4 Gravis GrIP | |
294 | ~~~~~~~~~~~~~~~ | |
295 | Gravis GrIP protocol is supported by the grip.c module. It currently | |
296 | supports: | |
297 | ||
298 | * Gravis GamePad Pro | |
299 | * Gravis BlackHawk Digital | |
300 | * Gravis Xterminator | |
301 | * Gravis Xterminator DualControl | |
302 | ||
303 | All these devices are autodetected, and you can even use any combination | |
304 | of up to two of these pads either chained together or using an Y-cable on a | |
305 | single gameport. | |
306 | ||
307 | GrIP MultiPort isn't supported yet. Gravis Stinger is a serial device and is | |
308 | supported by the stinger driver. Other Gravis joysticks are supported by the | |
309 | analog driver. | |
310 | ||
311 | 3.5 FPGaming A3D and MadCatz A3D | |
312 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
313 | The Assassin 3D protocol created by FPGaming, is used both by FPGaming | |
314 | themselves and is licensed to MadCatz. A3D devices are supported by the | |
315 | a3d.c module. It currently supports: | |
316 | ||
317 | * FPGaming Assassin 3D | |
318 | * MadCatz Panther | |
319 | * MadCatz Panther XL | |
320 | ||
321 | All these devices are autodetected. Because the Assassin 3D and the Panther | |
322 | allow connecting analog joysticks to them, you'll need to load the analog | |
323 | driver as well to handle the attached joysticks. | |
324 | ||
325 | The trackball should work with USB mousedev module as a normal mouse. See | |
326 | the USB documentation for how to setup an USB mouse. | |
327 | ||
328 | 3.6 ThrustMaster DirectConnect (BSP) | |
329 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
330 | The TM DirectConnect (BSP) protocol is supported by the tmdc.c | |
331 | module. This includes, but is not limited to: | |
332 | ||
333 | * ThrustMaster Millenium 3D Inceptor | |
334 | * ThrustMaster 3D Rage Pad | |
335 | * ThrustMaster Fusion Digital Game Pad | |
336 | ||
337 | Devices not directly supported, but hopefully working are: | |
338 | ||
339 | * ThrustMaster FragMaster | |
340 | * ThrustMaster Attack Throttle | |
341 | ||
342 | If you have one of these, contact me. | |
343 | ||
344 | TMDC devices are autodetected, and thus no parameters to the module | |
345 | are needed. Up to two TMDC devices can be connected to one gameport, using | |
346 | an Y-cable. | |
347 | ||
348 | 3.7 Creative Labs Blaster | |
349 | ~~~~~~~~~~~~~~~~~~~~~~~~~ | |
350 | The Blaster protocol is supported by the cobra.c module. It supports only | |
351 | the: | |
352 | ||
353 | * Creative Blaster GamePad Cobra | |
354 | ||
355 | Up to two of these can be used on a single gameport, using an Y-cable. | |
356 | ||
357 | 3.8 Genius Digital joysticks | |
358 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
359 | The Genius digitally communicating joysticks are supported by the gf2k.c | |
360 | module. This includes: | |
361 | ||
362 | * Genius Flight2000 F-23 joystick | |
363 | * Genius Flight2000 F-31 joystick | |
364 | * Genius G-09D gamepad | |
365 | ||
366 | Other Genius digital joysticks are not supported yet, but support can be | |
367 | added fairly easily. | |
368 | ||
369 | 3.9 InterAct Digital joysticks | |
370 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
371 | The InterAct digitally communicating joysticks are supported by the | |
372 | interact.c module. This includes: | |
373 | ||
374 | * InterAct HammerHead/FX gamepad | |
375 | * InterAct ProPad8 gamepad | |
376 | ||
377 | Other InterAct digital joysticks are not supported yet, but support can be | |
378 | added fairly easily. | |
379 | ||
380 | 3.10 PDPI Lightning 4 gamecards | |
381 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
382 | PDPI Lightning 4 gamecards are supported by the lightning.c module. | |
383 | Once the module is loaded, the analog driver can be used to handle the | |
384 | joysticks. Digitally communicating joystick will work only on port 0, while | |
385 | using Y-cables, you can connect up to 8 analog joysticks to a single L4 | |
386 | card, 16 in case you have two in your system. | |
387 | ||
388 | 3.11 Trident 4DWave / Aureal Vortex | |
389 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
390 | Soundcards with a Trident 4DWave DX/NX or Aureal Vortex/Vortex2 chipsets | |
391 | provide an "Enhanced Game Port" mode where the soundcard handles polling the | |
392 | joystick. This mode is supported by the pcigame.c module. Once loaded the | |
393 | analog driver can use the enhanced features of these gameports.. | |
394 | ||
395 | 3.13 Crystal SoundFusion | |
396 | ~~~~~~~~~~~~~~~~~~~~~~~~ | |
397 | Soundcards with Crystal SoundFusion chipsets provide an "Enhanced Game | |
398 | Port", much like the 4DWave or Vortex above. This, and also the normal mode | |
399 | for the port of the SoundFusion is supported by the cs461x.c module. | |
400 | ||
401 | 3.14 SoundBlaster Live! | |
402 | ~~~~~~~~~~~~~~~~~~~~~~~~ | |
403 | The Live! has a special PCI gameport, which, although it doesn't provide | |
404 | any "Enhanced" stuff like 4DWave and friends, is quite a bit faster than | |
405 | it's ISA counterparts. It also requires special support, hence the | |
406 | emu10k1-gp.c module for it instead of the normal ns558.c one. | |
407 | ||
408 | 3.15 SoundBlaster 64 and 128 - ES1370 and ES1371, ESS Solo1 and S3 SonicVibes | |
409 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
410 | These PCI soundcards have specific gameports. They are handled by the | |
411 | sound drivers themselves. Make sure you select gameport support in the | |
412 | joystick menu and sound card support in the sound menu for your appropriate | |
413 | card. | |
414 | ||
415 | 3.16 Amiga | |
416 | ~~~~~~~~~~ | |
417 | Amiga joysticks, connected to an Amiga, are supported by the amijoy.c | |
418 | driver. Since they can't be autodetected, the driver has a command line. | |
419 | ||
420 | amijoy.map=<a>,<b> | |
421 | ||
422 | a and b define the joysticks connected to the JOY0DAT and JOY1DAT ports of | |
423 | the Amiga. | |
424 | ||
425 | Value | Joystick type | |
426 | --------------------- | |
427 | 0 | None | |
428 | 1 | 1-button digital joystick | |
429 | ||
430 | No more joystick types are supported now, but that should change in the | |
431 | future if I get an Amiga in the reach of my fingers. | |
432 | ||
433 | 3.17 Game console and 8-bit pads and joysticks | |
434 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
435 | See joystick-parport.txt for more info. | |
436 | ||
437 | 3.18 SpaceTec/LabTec devices | |
438 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
439 | SpaceTec serial devices communicate using the SpaceWare protocol. It is | |
440 | supported by the spaceorb.c and spaceball.c drivers. The devices currently | |
441 | supported by spaceorb.c are: | |
442 | ||
443 | * SpaceTec SpaceBall Avenger | |
444 | * SpaceTec SpaceOrb 360 | |
445 | ||
446 | Devices currently supported by spaceball.c are: | |
447 | ||
448 | * SpaceTec SpaceBall 4000 FLX | |
449 | ||
450 | In addition to having the spaceorb/spaceball and serport modules in the | |
451 | kernel, you also need to attach a serial port to it. to do that, run the | |
452 | inputattach program: | |
453 | ||
454 | inputattach --spaceorb /dev/tts/x & | |
455 | or | |
456 | inputattach --spaceball /dev/tts/x & | |
457 | ||
458 | where /dev/tts/x is the serial port which the device is connected to. After | |
459 | doing this, the device will be reported and will start working. | |
460 | ||
461 | There is one caveat with the SpaceOrb. The button #6, the on the bottom | |
462 | side of the orb, although reported as an ordinary button, causes internal | |
463 | recentering of the spaceorb, moving the zero point to the position in which | |
464 | the ball is at the moment of pressing the button. So, think first before | |
465 | you bind it to some other function. | |
466 | ||
467 | SpaceTec SpaceBall 2003 FLX and 3003 FLX are not supported yet. | |
468 | ||
469 | 3.19 Logitech SWIFT devices | |
470 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
471 | The SWIFT serial protocol is supported by the warrior.c module. It | |
472 | currently supports only the: | |
473 | ||
474 | * Logitech WingMan Warrior | |
475 | ||
476 | but in the future, Logitech CyberMan (the original one, not CM2) could be | |
477 | supported as well. To use the module, you need to run inputattach after you | |
478 | insert/compile the module into your kernel: | |
479 | ||
480 | inputattach --warrior /dev/tts/x & | |

482 | /dev/tts/x is the serial port your Warrior is attached to. | |
483 | ||
484 | 3.20 Magellan / Space Mouse | |
485 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
486 | The Magellan (or Space Mouse), manufactured by LogiCad3d (formerly Space | |
487 | Systems), for many other companies (Logitech, HP, ...) is supported by the | |
488 | joy-magellan module. It currently supports only the: | |
489 | ||
490 | * Magellan 3D | |
491 | * Space Mouse | |
492 | ||
493 | models, the additional buttons on the 'Plus' versions are not supported yet. | |
494 | ||
495 | To use it, you need to attach the serial port to the driver using the | |
496 | ||
497 | inputattach --magellan /dev/tts/x & | |
498 | ||
499 | command. After that the Magellan will be detected, initialized, will beep, | |
500 | and the /dev/input/jsX device should become usable. | |
501 | ||
502 | 3.21 I-Force devices | |
503 | ~~~~~~~~~~~~~~~~~~~~ | |
504 | All I-Force devices are supported by the iforce module. This includes: | |
505 | ||
506 | * AVB Mag Turbo Force | |
507 | * AVB Top Shot Pegasus | |
508 | * AVB Top Shot Force Feedback Racing Wheel | |
509 | * Logitech WingMan Force | |
510 | * Logitech WingMan Force Wheel | |
511 | * Guillemot Race Leader Force Feedback | |
512 | * Guillemot Force Feedback Racing Wheel | |
513 | * Thrustmaster Motor Sport GT | |
514 | ||
515 | To use it, you need to attach the serial port to the driver using the | |
516 | ||
517 | inputattach --iforce /dev/tts/x & | |
518 | ||
519 | command. After that the I-Force device will be detected, and the | |
520 | /dev/input/jsX device should become usable. | |
521 | ||
522 | In case you're using the device via the USB port, the inputattach command | |
523 | isn't needed. | |
524 | ||
525 | The I-Force driver now supports force feedback via the event interface. | |
526 | ||
527 | Please note that Logitech WingMan *3D devices are _not_ supported by this | |
528 | module, rather by hid. Force feedback is not supported for those devices. | |
529 | Logitech gamepads are also hid devices. | |
530 | ||
531 | 3.22 Gravis Stinger gamepad | |
532 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
533 | The Gravis Stinger serial port gamepad, designed for use with laptop | |
534 | computers, is supported by the stinger.c module. To use it, attach the | |
535 | serial port to the driver using: | |
536 | ||
537 | inputattach --stinger /dev/tty/x & | |
538 | ||
539 | where x is the number of the serial port. | |
540 | ||
541 | 4. Troubleshooting | |
542 | ~~~~~~~~~~~~~~~~~~ | |
543 | There is quite a high probability that you run into some problems. For | |
544 | testing whether the driver works, if in doubt, use the jstest utility in | |
545 | some of its modes. The most useful modes are "normal" - for the 1.x | |
546 | interface, and "old" for the "0.x" interface. You run it by typing: | |
547 | ||
548 | jstest --normal /dev/input/js0 | |
549 | jstest --old /dev/input/js0 | |
550 | ||
551 | Additionally you can do a test with the evtest utility: | |
552 | ||
553 | evtest /dev/input/event0 | |
554 | ||
555 | Oh, and read the FAQ! :) | |
556 | ||
557 | 5. FAQ | |
558 | ~~~~~~ | |
559 | Q: Running 'jstest /dev/js0' results in "File not found" error. What's the | |
560 | cause? | |
561 | A: The device files don't exist. Create them (see section 2.2). | |
562 | ||
563 | Q: Is it possible to connect my old Atari/Commodore/Amiga/console joystick | |
564 | or pad that uses a 9-pin D-type cannon connector to the serial port of my | |
565 | PC? | |
566 | A: Yes, it is possible, but it'll burn your serial port or the pad. It | |
567 | won't work, of course. | |
568 | ||
569 | Q: My joystick doesn't work with Quake / Quake 2. What's the cause? | |
570 | A: Quake / Quake 2 don't support joystick. Use joy2key to simulate keypresses | |
571 | for them. | |
572 | ||
573 | 6. Programming Interface | |
574 | ~~~~~~~~~~~~~~~~~~~~~~~~ | |
575 | The 1.0 driver uses a new, event based approach to the joystick driver. | |
576 | Instead of the user program polling for the joystick values, the joystick | |
577 | driver now reports only any changes of its state. See joystick-api.txt, | |
578 | joystick.h and jstest.c included in the joystick package for more | |
579 | information. The joystick device can be used in either blocking or | |
580 | nonblocking mode and supports select() calls. | |
581 | ||
582 | For backward compatibility the old (v0.x) interface is still included. | |
583 | Any call to the joystick driver using the old interface will return values | |
584 | that are compatible to the old interface. This interface is still limited | |
585 | to 2 axes, and applications using it usually decode only 2 buttons, although | |
586 | the driver provides up to 32. |
