 Posted: Tue Aug 19, 2014 4:15 am Post subject: Gamepad Emulator |
 |
|
Is there any way to emulate a gamepad? Its quite easy to find tools to do the other way around, to map your gamepad buttons to keyboard keys, but what I want is the opposite: I don't have a gamepad, I want to pretend I have one using my keyboard.
EDIT#1: The gamepad events seem to be something like this:
http://askubuntu.com/questions/14457/remapping-both-mouse-and-keyboard-to-a-gamepad
but I have no idea how to fake them. Is there anything like xdotool that can do that?

I tried to do something else in the past quite similar but did not succeed.
It all depends how to generate those key events and how to map them |

Well yeah, my dilemma is how to even generate those key events - mapping them to something else should be more or less trivial, I hope. Don't you have an idea on how to generate those?

Well half of the solution is to use xmodmap.
Though I will have to experiment how to change my events to something useful
https://wiki.archlinux.org/index.php/xmodmap
My events are from this kind:
| Code: | Aug 26 16:57:26 localhost logger: ACPI event unhandled: hotkey ATKD 00000053 00000000
Aug 26 16:57:28 localhost kernel: asus_laptop: Unknown key 52 pressed

Well when I find time I will make some tests.
Basically the x-server is forced to reasign those events, it is now all a matter to write some new rules and test them out here.
The other path is to make your own input device driver altering an existing version of your keyboard and hardcode the desired abilities. |

I've used this before but completely forgot about its existence... thanks for the reminder. I will try it out and see how much I can achieve.

The events are defined in /usr/src/linux/include/uapi/linux/input.h
The block is:
| Code: |
#define BTN_JOYSTICK 0x120
#define BTN_TRIGGER 0x120
#define BTN_THUMB 0x121
#define BTN_THUMB2 0x122
#define BTN_TOP 0x123
#define BTN_TOP2 0x124
#define BTN_PINKIE 0x125
#define BTN_BASE 0x126
#define BTN_BASE2 0x127
#define BTN_BASE3 0x128
#define BTN_BASE4 0x129
#define BTN_BASE5 0x12a
#define BTN_BASE6 0x12b
#define BTN_DEAD 0x12f |
There might be might be more in the file though.

Okay, I think that the answer is here:
http://steamcommunity.com/app/221410/discussions/0/558748653738497361/
It is specifically for XBOX controllers, but that should be good enough. Basically you need xboxdrv to remap something into XBOX events, if I understood correctly. I haven't fully tested that though.
