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

@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

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.

spud11

@mediamogul That's interesting. I'd just been setting up Defender for the Sam Coupe and had been doing the same - hyperspace and smart bombs alongside the fire button. If you have enough buttons, you can even make reverse and thrust work with buttons.

The other thing that I just checked before you replied was that you can retain a standard $1 or $2 configuration for a system whilst the specific $3 will override for the individual game only, and you've confirmed that that works too.

As you said, the Colecovision (which I set up about a month ago) will really benefit from this. I was finding that, despite having about 12 buttons on my arcade cabinet, it was getting pretty hard to create a standardised control scheme. It'll be much easier now that I know I can just do per-game schemes while maintaining a standard default scheme for those games that just require the default.

No sweat on changing the guide, but I must admit both this individualised process and the "launch executable" process you discovered a couple of months ago probably should end up being documented. (Also, I can't recall whether the "launch macro" process is also covered in the guide, but suspect not).

Is there any performance impact to using xboxdrv for all games? My need for xboxdrv is only for 4-way restriction - for arcade. I use Controlblock and I found that the following logic works to use xboxdrv only for restricted games and Controlblock for the rest:

One time:

Using Joystick Selection (https://github.com/meleu/RetroPie-joystick-selection) I mapped the xboxdrv #1 to player 1 and #2 to player 2 for "arcade" only. I used the "by-name" method, which seems to have some logic for "not connected"

Scripts:

launch xboxdrv/restricted (for player 1 + player 2) when emulationstation starts
a runcommand-onstart.sh script checks if launched rom is in RestrictedArcade list. If it is - do nothing. If it is not in the list - kill xboxdrv.
(the Controlblock joystics are automatically mapped if xboxdrive is killed)
*runcommand-onend.sh checks if xboxdrv is running. If not - launches for each player/restricted.

Thoughts?

Disclaimer: newbie, limited programming skills, haven't tested it for long enough :-)

@guydot said in Guide: Advanced Controller Mappings:

None that I've noticed. I usually launch two instances for player one and two controls and have never had a problem.

Thoughts?

No, not really. That's more or less how I use it myself.

Disclaimer: newbie, limited programming skills, haven't tested it for long enough :-)

You're doing pretty good. Most people, including myself, struggle with this in the beginning. It really does pay off though. Games like Pac-Man just can't be played well with more than four available directions. Sure, you can boot them up and show them off, but you'll never get very far without the restriction.

guydot

@mediamogul I was too happy too soon. It is not working consistently. I am almost ready to give up. The driver works well first time I launch a game (creates JS2 and JS3), but in subsequent launches I noticed that the driver creates JS4 and the game does not respond. I wonder if anybody has been successful with Contronlblock + xboxdrv...

The one thing that I noticed, but I am not sure if it has any significance, is that the Controlblock joystics are not listed in /dev/input/by-id/

In the xboxdrv command line I used the (controlblock joysticks) event numbers.

Not sure if it makes sense...

mediamogul

@guydot said in Guide: Advanced Controller Mappings:

It could be that the previous instances of xboxdrv are not being killed when the emulator/port exits. Looking back over your previous post, I don't see you mention a command to killall xboxdrv in the runcommand-onend script. If it is in fact there, make sure you're using sudo before the killall command. Otherwise it won't have the proper permissions.

I am not sure if it has any significance, is that the Controlblock joystics are not listed in /dev/input/by-id/

You might also try looking at /dev/input/by-path/.

@mediamogul Hi. I'm having a few problems with ScummVM and mapping my joystick 1 to operate like a mouse.

I have a bluetooth keyboard which has a built in touchpad and I can use that to navigate in game perfectly. My joystick 2 is also natively working as a joystick, albeit the axes are mixed up.

I've followed the guide, but I think I've got myself confused. This is the first time I've tried to mimic a mouse.

Do I need to start from scratch and determine what event number is the keyboard/touchpad and go from there (using cat /proc/bus/input/devices)?

So far I have:

@spud11

Does xboxdrv throw up any errors? At some point I changed the guide to suggest redirecting all errors to the Runcommand log rather than /dev/null. That might be helpful here. Just replace:

> /dev/null 2>&1

with

>> /dev/shm/runcommand.log 2>&1

As long as you have an otherwise working xboxdrv command, the following two lines should be all that's required to add full mouse control to whatever the first axis is on the controller you're trying to map, with buttons 'A' and 'B' acting as left/right click..

--ui-axismap X1=REL_X:10,Y1=REL_Y:10 \
--ui-buttonmap a=BTN_LEFT,b=BTN_RIGHT

spud11

@mediamogul Thanks. You were 100% right. I found an error - just a missing ; which I've added back in. Thanks again.
