The evtest displays lots of entries when a press a button and lots lots lots
This also happens with one of my controllers. In my case it meant that the axis input was so sensitive that it was being activated whenever any button was pressed. To prevent this from carrying over to the virtual controller, I had to add the
--deadzone 4000
. However, you'll still need a way to discern the actual button information from all the extra information you're given inevtest
. This takes a bit of work, as you'll have to barely tap each button and then scroll up to the very top of the resulting input and see what the first listing was before all the garbage. -

How can I map the hat
Mapping the dpad hatswitch from a physical controller to the xboxdrv virtual controller is done as follows:
--evdev-absmap ABS_HAT0X=dpad_x,ABS_HAT0Y=dpad_y
From there you would normally map keys to it like any other axis:
--ui-axismap dpad_x=KEY_LEFT:KEY_RIGHT,dpad_y=KEY_UP:KEY_DOWN
However, if you want to the dpad to be seen as button presses rather than an axis with the new virtual controller, you would add:
--dpad-as-button
Once this has been added you can now key-map the dpad with
--ui-buttonmap
such as:--ui-buttonmap du=KEY_UP,dd=KEY_DOWN,dl=KEY_LEFT,dr=KEY_RIGHT

Thanks mediamomogul!
Now the script works, but I have another problem.
If I enter the Atari5200 emulator, the controller commands doesn't work, but if I go to my SSH console and I type (in the /opt/retropie/configs/all directory)
./runcommand-onstart.sh atari800 + Return
, while the emulator is running, the controller starts working as expected (yay!).It seems that the script is finally correct, but it doesn't seem to start when the atari emulator il launched.
Am I forgetting something ?
-
I'm afraid I'll have to defer this question to @MadHorse, who has a better understanding of this area. In the mean time, go ahead and post the full contents of your
runcommand-onstart.sh
file and I'll see if anything jumps out. -
Thanks !
Here is my
runcommand-onstart.sh

Thanks for any help !

Ok, I've found the problem...
The
runcommand-onstart.sh
script passes as first parameters ($1
) the stringatari5200
, and not the stringatari800
, making the case into the script to skip the execution of the driver.In my script I've changed all the occurrances of
atari800
intoatari5200
and it now works !!Thanks to everybody for all the help !
-
Well done sir! Case scripting is an area that I haven't had time to fully explore yet, so these posts are always very informative.

@mediamogul sorry for acting like a lazy guy here, but can you share with us a way to set only one button to act like pressing two buttons?
The goal is to put a button on a bartop to do "exit emulator" function (usually start+select).
Thanks in advance.
-
Not a problem. Let's say that the keyboard key you're looking to map to 'start+select' is the 'Escape' key. Also, we'll assume that 'Back' is being used as a stand-in for 'Select', due to the lack of a 'Select' button option on the virtual XBox controller. The mapping would read as:
--ui-buttonmap back+start=KEY_ESC
If you ever run into software that uses a key combination to exit, such as 'ctrl+escape', the alteration is nothing more complicated than:
--ui-buttonmap back+start=KEY_LEFTCTRL+KEY_ESC
or possibly:
--ui-buttonmap back+start=KEY_RIGHTCTRL+KEY_ESC

-Is it possible to use xboxdrv with a PS3 controller?
-Should I disable/remove PS3 Bluetooth driver?
-Should I try configuring it wireless or connected?And "ls /dev/input/by-id/" doesn't work.
Any help is welcome.
Thanks in advance!

@PolluxNL said in Guide: Advanced Controller Mappings:
-Is it possible to use xboxdrv with a PS3 controller?
It is indeed.
-Should I disable/remove PS3 Bluetooth driver?
I can't really say, but it's likely that it will conflict otherwise.
-Should I try configuring it wireless or connected?
I believe problems arise when configured wirelessly, due to the bluetooth connection being dropped when sleeping.
And "ls /dev/input/by-id/" doesn't work.
you can also use it's joystick event number at
/dev/input/jsX
, where x is likely to be 0. -
Hi mediamogul!
Your guide is really comprehensive, thank you!I got the basics, but xboxdrv gives me trouble using the calibration parameter.
If I don't calibrate my controller the output from the control stick is to low to be useful.
If I use --calibration x1=40:128:207,y1=50:128:207 \ (in my case an adapted N64 controller) the stick returns higher values, but it almost behaves like a button jumping between the min and max values (32767/-32767) with nothing inbetween.
Is there another way to increase the analog output? Maybe just multipling the original values by a factor of 2 would do the trick but I have no idea how to approach this idea and I can't get my head around the filtering concept.
I'm really looking forward to a solution, this is really a showstopper for my usecase.
These are my settings:
sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv
--evdev /dev/input/event2
--silent
--detach-kernel-driver
--force-feedback
--deadzone-trigger 15%
--deadzone 15%
--device-name "N64 Player 1"
--evdev-absmap ABS_X=x1,ABS_Y=y1,ABS_RZ=x2,ABS_Z=y2,ABS_HAT0X=dpad_x,ABS_HAT0Y=dpad_y
--evdev-keymap BTN_THUMB=a,BTN_THUMB2=b,BTN_BASE=lb,BTN_BASE2=rb,BTN_BASE3=tl,BTN_BASE4=start
--ui-axismap lt=void,rt=void
--ui-buttonmap tr=void,guide=void,back=void,x=void,y=void
--calibration x1=40:128:207,y1=50:128:207 \ -
Unfortunately, this is a situation I've never run into personally. The few controllers that I've had to use this on seemed to come into line immediately. I like your idea about multiplying the values and I'm curious myself to see what effect that would have. Also, it might be worth trying the widest possible range of values as well by adjusting the config to:
--calibration x1=-32768:0:32767,y1=-32768:0:32767 \
Definitely keep me updated.
-
Thanks for pointing me to a solution!
I tried this calibration before, but the values were still too low. The x and y output needs to be in the 30000 range to be correctly registered. With this calibration they were around 18000 which is much better than the former ~200.
Through trial and error I figured out if you use--calibration x1=-16384:0:16384,y1=-16384:0:16384 \
you get really usable results in the 32000 range and everything works fine in the emulationstation controller-configuration GUI and retroarch.
So my configuration for a real N64 controller using the HiuJia usb adapter looks like this (the deadzone probably still needs some tweaking) :
sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv \ --evdev /dev/input/event2 \ --silent \ --detach-kernel-driver \ --force-feedback \ --deadzone-trigger 15% \ --deadzone 15% \ --device-name "N64 Player 1" \ --evdev-absmap ABS_X=x1,ABS_Y=y1,ABS_RZ=x2,ABS_Z=y2,ABS_HAT0X=dpad_x,ABS_HAT0Y=dpad_y \ --evdev-keymap BTN_THUMB=a,BTN_THUMB2=b,BTN_BASE=lb,BTN_BASE2=rb,BTN_BASE3=tl,BTN_BASE4=start \ --ui-axismap lt=void,rt=void \ --ui-buttonmap tr=void,guide=void,back=void,x=void,y=void \ --calibration x1=-16384:0:16384,y1=-16384:0:16384 \
Thanks again for the awesome controller guide!

Not a problem. Thank you for posting your findings. I'm glad it's working well now.

I removed all references to altering
emulator.cfg
files for key-mapping a system/port in favor of an easily sustainable and much simpler approach using a basic if/else statement. Anyone having trouble with this in the past may wish to reexamine the process. @MadHorse's more advanced case statement technique remains the same. -
do you need to have the latest kernel installed.
i have kernel 4.1.21-v7+. per Xbox360 wireless controllers - receiver connectivity issuesim also have a 8bitdo. I know that Rion had problems with getting his to work.
im just starting out some where
-
I believe that's only necessary when using xboxdrv as a driver for an actual Xbox controller. I've never had to worry about a particular kernel version myself.
-
ok cool.
one less thing for me to worry about.
guess it is just in my coding. -
So i have been messing around trying to get to work.
so far i have go a whole lot of nothing.I have done what the advance guide said with a little tweeking for my controler
here is my controler info
I: Bus=0005 Vendor=3810 Product=0009 Version=0100 N: Name="8Bitdo FC30 Pro" P: Phys=b8:27:eb:47:c7:78 S: Sysfs=/devices/platform/soc/3f201000.uart/tty/ttyAMA0/hci0/hci0:11/0005:3810:0009.0003/input/input8 U: Uniq=e4:17:d8:7a:6a:7d H: Handlers=js0 event2 B: PROP=0 B: EV=1b B: KEY=ffff0000 0 0 0 0 0 0 0 0 0 B: ABS=30627 B: MSC=10
and when i run
ls /dev/input/by-id/ usb-1d57_ad02-event-kbd usb-_Mini_Keyboard-event-kbd usb-1d57_ad02-if01-event-mouse usb-_Mini_Keyboard-if01-event-mouse usb-1d57_ad02-if01-mouse usb-_Mini_Keyboard-if01-mouse
no id for my controller so i have to use the event number

My system is
Raspberry pi 3 running 4.1
im trying to get my 8Bitdo FC30 Pro to do anything, if i can get something i can build from there.I have been only focused on scummVM. so i know that the other Emulators have things wrong
right now i have nothing.
