Guide: Advanced Controller Mappings

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
## Name of the emulator
#echo $1 >> /dev/shm/runcommand.log

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 \

	--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 \

	--ui-axismap x1=REL_X:10,y1=REL_Y:10 \

@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

if [ "$1" = "scummvm" ]
then

	--ui-axismap x2=void

fi

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.

mediamogul

@ExarKunIv

You can change the cursor speed by altering:

--ui-axismap x1=REL_X:10,y1=REL_Y:10 \

Changing the number 10 anything higher will increase the speed. It can also be brought down as low as 01 to decrease the speed as well.

ExarKunIv

@mediamogul

again I thank you

mediamogul

@ExarKunIv

Not a problem. Thanks to you as well. Without this issue, the guide would have remained essentially broken.

ExarKunIv

now that i have something to go off that is working, im trying to get more configs to work for other systems.

so my question is how to you let the system know that you want the axismap to be fore a joystick.

im trying to get my apple 2 to work. i go the keyboard going :)
just need it to see my axismap as a joystick not a mouse, or will do it do that automatically?

i want to try my best before i post my config and have someone point out what im doing wrong. need to learn it somehow :P

mediamogul

@ExarKunIv

For the Apple 2, I just mapped a series of keyboard keys to the joystick and did the same for the action button. I also mapped the various application commands so that they line up with the defaults in RetroArch just because it's easier for me to remember. Once done, I launched the software and invoked the options menu (now 'select+x' due to my mapping) and from there it allowed me to map the controller in a similar way to Emulation Station. Obviously there are many ways to approach this to suit anyone's preference, but if it helps, I'll include my mapping below for reference.
