It give me this back

Joystick (Xbox Gamepad (userspace driver)) has 6 axes (X, Y, Rx, Ry, Hat0X, Hat0Y)
and 13 buttons (BtnX, BtnY, BtnTL, BtnTR, BtnTR2, BtnSelect, BtnStart, BtnMode, BtnThumbL, BtnThumbR, ?, ?, ?).
Testing ... (interrupt to exit)
Axes:  0:     0  1:     0  2:     0  3:     0  4:     0  5:     0 
Buttons:  0:off  1:off  2:off  3:off  4:off  5:off  6:off  7:off  8:off  9:off 10:off 11:off 12:off

And nothing testing, neither evtest.
What that it means?

@javisousa20

So, while the testing interface was up, you didn't get any response from using the touchpad, or from pressing the buttons?

javisousa20

@mediamogul
Exactly, I don't get any reponse. I have tested with all the controllers that enable xboxdrv without success.

mediamogul

@javisousa20

I'm afraid that may mean it's not going to work. Usually, if there's an issue, xboxdrv will simply refuse to create the virtual controller and throw an error. The fact that it is created, but has no response likely means there's nothing to troubleshoot and that the two are just not compatible.

javisousa20

@mediamogul
Well, thanks for the answer, I'll try to do some tests even though we can not do anything. The best way to test the changes is as follows?

sudo killall xboxdrv
sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv ((...changes...))
reboot

Thanks for the help!

On something like this, the best advice I can give is to keep throwing ideas at the problem as you have them. Whenever I find myself in uncharted territory, trial and error is often the mother of resolution.

Hi, I think the problem is when I reboot to initialize xboxdrv. I have tried to use the following code

sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv 
 --evdev /dev/input/event1 
 --evdev-debug 
 --evdev-keymap BTN_LEFT=LB,BTN_RIGHT=RB

It give me this back when I press the BTN_LEFT, also with BTN_RIGHT

EV_KEY BTN_LEFT 1
X1:     0 Y1:     0  X2:     0 Y2:     0  du:0 dd:0 dl:0 dr:0  back:0 guide:0 start:0  TL:0 TR:0  A:0 B:0 X:0 Y:0  LB:1 RB:0  LT:  0 RT:  0
EV_KEY BTN_LEFT 0
X1:     0 Y1:     0  X2:     0 Y2:     0  du:0 dd:0 dl:0 dr:0  back:0 guide:0 start:0  TL:0 TR:0  A:0 B:0 X:0 Y:0  LB:0 RB:0  LT:  0 RT:  0
EV_KEY BTN_LEFT 1
X1:     0 Y1:     0  X2:     0 Y2:     0  du:0 dd:0 dl:0 dr:0  back:0 guide:0 start:0  TL:0 TR:0  A:0 B:0 X:0 Y:0  LB:1 RB:0  LT:  0 RT:  0

It seems that the emulation to the LB button works, but when I restart to initialize xboxdrv, the result is lost:

sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv 
 --evdev /dev/input/event1 
 --evdev-debug
EV_KEY BTN_LEFT 1
X1:     0 Y1:     0  X2:     0 Y2:     0  du:0 dd:0 dl:0 dr:0  back:0 guide:0 start:0  TL:0 TR:0  A:0 B:0 X:0 Y:0  LB:0 RB:0  LT:  0 RT:  0
EV_KEY BTN_LEFT 0
X1:     0 Y1:     0  X2:     0 Y2:     0  du:0 dd:0 dl:0 dr:0  back:0 guide:0 start:0  TL:0 TR:0  A:0 B:0 X:0 Y:0  LB:0 RB:0  LT:  0 RT:  0

There may be something that I am doing wrong, Do I have to write it in rc.local?

mediamogul

@javisousa20

I believe you're right. xboxdrv is allowing the map to happen without error, but when the virtual controller is produced, those buttons don't seem to be communicating as they should. If I had to guess, it may be because you're mapping a mouse event. I've never done that myself and while it's technically possible and xboxdrv doesn't complain, it's just not communicating for some reason.

javisousa20

@mediamogul
Is there any way to start xboxdrv without rebooting? Or what is the way to start the configuration of xboxdrv at start? Is it to write the code in rc.local? Because I'm having troubles in that case

mediamogul

@javisousa20

You can always kill it at any time with

sudo killall xboxdrv

When testing, you can just created a script, say in your home folder and launch it to see if it's working. If not, kill it, alter it and launch it again.

It would not work for what I try to get, xboxdrv does not modify the first virtual event (ex: event2, js0) if I have not used killall before, either through rc.local or a script or directly from the xboxdrv command, but that creates a new event (and new js) that does not appear in /dev /input because it always exceeds the limit of defined controllers for the driver. The problem was that I could not run xboxdrv after I had used the killall command, only if I rebooted... or I don't know how.
But I think I've got it, I should try a script like you said, but for now I've managed to make it work by making the following change in rc.local:


sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv \
 --evdev /dev/input/event1 \
 --silent \
 --mimic-xpad \
 --trigger-as-button \
 --evdev-keymap BTN_LEFT=LB,BTN_RIGHT=RB,KEY_CONFIG=LT,KEY_SEARCH=RT,KEY_PLAYPAUSE=A,KEY_PREVIOUSSONG=X,KEY_NEXTSONG=B,KEY_VOLUMEUP=Y,KEY_VOLUMEDOWN=back

"/opt/retropie/supplementary/xboxdrv/bin/xboxdrv" --daemon --detach --dbus disabled --detach-kernel-driver --id 0 --led 2 --deadzone 4000 --silent --trigger-as-button --next-controller --id 1 --led 3 --deadzone 4000 --silent --trigger-as-button

exit 0

The first call is my design for xboxdrv and the second one is the default one when enabling the driver from retropie config.
The problem with this method now comes from that to include that code in rc.local, when loading backpieces at the beginning, instead of entering emulationstation runs xboxdrv as expected from command line, but remains stopped in its last sentence:

Your Xbox/Xbox360 controller should now be available as:
 /dev/input/js0
 /dev/input/event2

Press Ctrl-C to quit

But I can't do nothing to quit, skip or enter in emulationstation directamente. (Or I may not know how)
I can only enter emulationstation using SSH. There I can map all the keys and buttons without problems (although I still have to try the touchpad as a joystick).
It is an advance, I would like to take advantage of your knowledge in programming that I don't have to finish polishing it, there may be more interested people.

Ok sorry, I forgot the &. Now it's working well!
When I want to use lxde desktop I can't use the keyboard or mouse, how can I end the xboxdrv process automatically when I want to access the desktop and restart it when I go back to retropie?

mediamogul

@javisousa20

So the virtual controller is preventing you from using a mouse and keyboard in lxde?

javisousa20

@mediamogul
Yes, if I run killall xboxdrv, I can control it normally again

mediamogul

@javisousa20

Well, as you know, the guide covers a method for starting and stopping xboxdrv maps using the runcommand-onstart/end scripts, but I don't think they come into play for lxde. I've never enabled lxde on my own setup, but I assume a script is created to launch it, located in the RetroPie menu. Making sure to work from a copy of that, you could try altering it to kill xboxdrv at the beginning of the script and relaunching it at the end.

javisousa20

@mediamogul
Thanks, I got what I wanted!
This is for runcommand-onstart.sh

#!/bin/sh

### Set variables for your joypad and emulator
### Basic Configuraions - Standard controller mappings

--mimic-xpad \
--trigger-as-button \
--evdev-keymap BTN_LEFT=LB,BTN_RIGHT=RB,KEY_CONFIG=LT,KEY_SEARCH=RT,KEY_PLAYPAUSE=A,KEY_PREVIOUSSONG=X,KEY_NEXTSONG=B,KEY_VOLUMEUP=Y,KEY_VOLUMEDOWN=back \

I would like to start from Kodi or Desktop, but if I delete the xboxdrv configuration in rc.local, I can not start xboxdrv when I press exit to enter in emulationstation. It does not work either leaving it in rc.local because it starts desktop/kodi with xboxdrv and does not allow me to use normal controls. Is there any chance of making a change in autostart.sh or in runcommand-onstart.sh to autostart running through runcommand?

On the other hand, I can't emulate the axes of the joystick, the REL_X / Y events go approximately from -60 to 60 depending on the speed with which I move on the touchpad, but I can not get them to work either by calibration, can it be a problem defining them using --ui-axismap?

Thank you very much!

I suppose you could create a script that can be selected from within lxde that would kill the desktop environment and launch xboxdrv, as well as Emulation Station if necessary. The same can actually be done from within Kodi but it's not as straightforward. You'll need to do some research on script addons, or even ways to add scripts as menu items.

I believe defining the outer deadzones as defined in the guide should take care of that. Have you given that a go?

It can be seen that in this case xboxdrv is not reading the REL axes, but I don't know why

@mediamogul Hi. I thought you might be interested in something I've just found out with xboxdrv. Not sure if you've already discovered this. It is possible to use the $3 case in runcommand-onstart.sh to make an xboxdrv script that works just for one game. I've been messing around with SimCoupe trying to see whether it has any standardised controls either for keyboard or joystick. It doesn't seem to have any, so, as I only want to play a couple of Sam Coupe games, I thought that it would be a good idea to try to create xboxdrv scripts for individual games. I've got one to work with the extract from my runcommand-onstart.sh file as follows:

I've included some case $1 scripts just so you can see it in context and, at the bottom , you will see the case $3 script for Manic Miner. This works for me.

I'm glad you posted this and I really should have put it into the guide by now. Individual game mapping comes in handy so often that it needs to be documented. A great example are all the Atari 2600/5200, Intellivision and Colecovision games that use unique keypad controls. Mapping them to something more sane on a modern controller increases their playability so much. Another good example is the Atari 2600 games that originally made use of two joysticks for extra buttons. I just recently made a map for the 2600 port of 'Stargate', that moves 'smartbombs', 'inviso' and 'hyperspace' alongside the normal 'fire' button on the same controller and it plays great.
