Guide: Advanced Controller Mappings

@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 \

@Capt_MorganCreek

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.

Capt_MorganCreek

@mediamogul

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!

@Capt_MorganCreek

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

mediamogul

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.

ExarKunIv

do you need to have the latest kernel installed.
i have kernel 4.1.21-v7+. per Xbox360 wireless controllers - receiver connectivity issues

im also have a 8bitdo. I know that Rion had problems with getting his to work.

im just starting out some where

mediamogul

@ExarKunIv

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.

ExarKunIv

ok cool.

one less thing for me to worry about.
guess it is just in my coding.

ExarKunIv

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 script

#!/bin/sh
## Uncomment one or all of the following if you need to find some information about the emulator or roms

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.

mediamogul

@ExarKunIv

Since you're just focusing on ScummVM at the moment, try running the full command, minus >/dev/null from the command line and see if it launches cleanly. All together, that woud be:

/opt/retropie/supplementary/xboxdrv/bin/xboxdrv \
	--evdev /dev/input/event2 \
	--silent \
	--detach-kernel-driver \
	--force-feedback \
	--mimic-xpad \
	--dpad-as-button \
	--trigger-as-button \
	--evdev-absmap ABS_X=x1,ABS_Y=y1,ABS_Z=x2,ABS_RZ=y2,ABS_HAT0X=dpad_x,ABS_HAT0Y=dpad_y \
	--evdev-keymap KEY_#304=a,KEY_#305=b,KEY_#307=x,KEY_#308=y,KEY_#312=lt,KEY_#313=rt,KEY_#310=lb,KEY_#311=rb,KEY_#317=tl,KEY_#318=tr,KEY_#314=back,KEY_#315=start \
	--calibration x1=-32767:0:32767,y1=-32767:0:32767,x2=-32767:0:32767,y2=-32767:0:32767 \
	--axismap -Y1=Y1,-Y2=Y2 \
	--ui-axismap x1=REL_X:10,y1=REL_Y:10 \
	--ui-buttonmap a=BTN_LEFT,b=BTN_RIGHT,start=KEY_F5,back=KEY_ESC \
	--ui-buttonmap guide=void,x=void,y=void,lb=void,rb=void,tl=void,tr=void,lt=void,rt=void,back=void \
	--ui-axismap x2=void

@mediamogul
thanks for the input

at first i got nothing, but then i put sudo in the front and i got this

Your Xbox/Xbox360 controller should now be available as:
  /dev/input/js1
  /dev/input/event3

Press Ctrl-C to quit

and it worked.
so it seems like i don't have the rights to have it run automatically.
or that is what it seems to me.

@ExarKunIv said in Guide: Advanced Controller Mappings:

You are exactly right. When the guide was written, I had extra steps in there that allowed xboxdrv to run at a user level because it was necessary for a certain part. I have since revised the guide to simplify the approach and it can now be used without those extra steps and apparently I overlooked correcting the case statement to account for this. I'll amend the guide.

Edit: In short, just add sudo to your case statement as you did above and it should work.

ExarKunIv

thank you so much.

glad that my problem will be able to help others also
:)

ExarKunIv

still no go.

have been messing around with my runcommand-onstart.sh
and still it will not launch

is what i have.
it seems like the runcommand it not starting.

do i need a

#!/bin/sh

at the start?

mediamogul

@ExarKunIv said in Guide: Advanced Controller Mappings:

I would definitely try it.

ExarKunIv

still nothing

mediamogul

@ExarKunIv

Try changing:

	--ui-axismap x2=void

to:

	--ui-axismap x2=void \

mediamogul

Also, remove the fifth line in your command:

    >/dev/null \

ExarKunIv

@mediamogul

that did it.

the controls work great.
Thank you so much

a quick thing. the mouse pointer slowly moves up.
where in my config would control that.
