Guide: Advanced Controller Mappings

Looking through here, this seems to work great for mapping a controller of any type, but would it work in mapping a keyboard input? I have the GPIO pins emulating key presses for the buttons on my portable pi, I've got them up and running for pretty much all games with a few wonky outliers, would I benefit from going through this trouble or should I just leave it as-is?

It looks like everything is right on your end. It's very helpful to see that your command launches directly from the command line without error. That should mean that it's also launching from rc.local and is just being ignored. I've never had that happen, but it could be that the original controller event is taking precedent and when you go to map in ES it reads the original event first. This isn't supposed to happen because xboxdrv is designed to render the original event inert to avoid these types of situations. It could be that it's unable to do this because of something unique to the NES30 setup.

Try deleting the original NES30 mapping from es_input.cfg, reboot and see if it can then read the xboxdrv virtual event. Just make sure you have something else mapped to control ES as a backup if it doesn't work. If it does work and the original NES30 event is conflicting, that conflict will of course still show up in other software as well.

I've never tried mapping a keyboard, but it should work, as you'd just be taking an event code from the keyboard and mapping it to a virtual controller event. Give it a shot. I'd be very interested to see how it goes.

Hi!

I'm following the wiki in order to try to use my Xbox One wired controller with the Retropie emulators that normally support keyboard only.

I've discovered the events generated by the pad, and I've noticed that the two triggers are registered as button events, nominally BTN_TL2 and BTN_TR2, and not as ABS events.

Should the command that launches xboxdrv look like this ?

sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv \
    --evdev /dev/input/by-id/usb-Microsoft_Controller_7EED8E7D89A9-event-joystick \
    --silent \
    --detach-kernel-driver \
    --force-feedback \
    --deadzone-trigger 15% \
    --deadzone 4000 \
    --mimic-xpad \
    --trigger-as-button \
    --evdev-absmap ABS_X=x1,ABS_Y=y1,ABS_RX=x2,ABS_RY=y2,ABS_HAT0X=dpad_x,ABS_HAT0Y=dpad_y \
    --evdev-keymap BTN_SOUTH=a,BTN_EAST=b,BTN_NORTH=x,BTN_WEST=y,BTN_TL=lb,BTN_TR=rb,BTN_TL2=lt,BTN_TR2=rt,BTN_THUMBL=tl,BTN_THUMBR=tr,BTN_MODE=guide,BTN_SELECT=back,BTN_START=start \
    &

Notice that I've used the --trigger-as-button option, and that the BTN_TL2=lt,BTN_TR2=rt button events are mapped in the --evdev-keymap option .

It looks fine to me. Have you tried using it yet?

Yess !

I works, but at first it didn't work because both Emulationstation and Retroarch detected both the Xbox One and the Xbox 360 controllers, giving priority to the former.

To make it functioning I had to do the following:

erase ~/.emulationstation/es_input.cfg
reconfigure Retroarch setting, making the Xbox 360 controller the first to be used by all emulators

I'm now going to try to configure the driver in order to use the controller with the Atari800 Emulator.

Thanks a lot !

Well i tested what you said. Did the hole thing using a clean install.

Still same problem. The only GamePad Emulationstation recognizes is NES 30 PRO and this is even without adding the Gamepad to /etc/udev/rules.d/99-bluetooth.rules by just paring the gamepad in RetroPie Setup using bluetooth - Configure Bluetooth Devices

When i drop down to command line and write this after reboot there is no Virtual X360 Gamepad registered

Then i start emulationstation again. Then its there but there are now not one but two gamepads detected. But Emulation station only responds to NES30 PRO Advanced Controller Configuration so that one good thing.

So why is this happening? Why are the commands a put in to /etc/rc.local ignored?

Is it because the Gamepad have not connect via Bluetooth yet? Cause it usually takes a while before that happens.

Just right when Emulationstation loads up.

But i have tried all the options in Configure Bluetooth Devices->Configure bluetooth connect mode from default, boot & background.

Please help.. Me...

When i check the log in /var/log/boot.log there is an error that it cant find "/dev/input/event2"

I'm not sure, but that is a very good suspect and would make sense. Earlier in this thread, this was also brought up as a possibility. I suggested forcing the controller to load by adding a command to do so before the xboxdrv command in rc.local. Adding a sleep command of a few seconds between the two probably wouldn't hurt either. I don't own a Bluetooth controller, so I've never had to attempt this, but after looking at back at that discussion, the following command might work:

rfcomm bind 0 XX:XX:XX:XX:XX:XX 1

substituting your controller's Blutooth address for "XX:XX:XX:XX:XX:XX" of course.

Did not work but a sleep 5 before helped sort of... But it completely hangs in the terminal window.

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

Press Ctrl-C to quit, use '--silent' to suppress the event output
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

So it reacts to my button presses but wont respond to Ctrl-C on my Keyboard that is attached. Is should just continue and start emulationstation but for some reason it wont.

My /etc/rc.local look like this. The silent command is there... strange...

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

# Print the IP address
_IP=$(hostname -I) || true
if [ "$_IP" ]; then
  printf "My IP address is %s\n" "$_IP"
fi

@Rion

That is most strange. As an experiment, you might try putting your xboxdrv command right before emulationstation is called in /opt/retropie/configs/all/autostart.sh rather than /etc/rc.local, as I believe it loads at a later time. That might give the controller the time it needs to pair.

Rion

@mediamogul

Removed the commands from /etc/rc.local and instead added like you suggested to autostart.sh
And the same thing happens again when i do that.... This is starting to get a bit frustrating...

Edit:

I think i found something here on the official Raspberry forums. A man named teeth_03 seams like he hade the same problem and solved it but i cant figure out how he did it even tough he describes it.

My Bin/Bash Kung-Fu is not as strong as i hoped.

It's like learning a parrot to talk. Its just repeats what you said and don't know why lol

mediamogul

@Rion

I just have noticed that your xboxdrv config has a small error.

The line...

	--evdev /dev/input/event2

should be:

	--evdev /dev/input/event2 \

I don't know if that was the source of your problem, but it would have caused the command to end at that point before any mapping occurs.

As far as the thread you posted, teeth_03 mentions that he didn't use the autostart.sh script, but one that launches Emulation Station. As I understand it, autostart.sh is the script that launches ES in Retropie. My only guess is that he's alluding to a script of his own creation or one that is used in some other distribution.

Rion

@mediamogul

Sorry about the missing "/" is just a type error. I forgot to add it when i posted. Its there in rc local.

Maby i just have to give up on a system-wide mapping for now and go with Key-Mapping For Individual Emulators instead.

I wanted to have a system wide configuration for the versability and for emulators like vice for c64.

But even if i can't get a system-wide mapping working on boot i can still configure the controller for Key-Mapping For Individual Emulators? Or am i mistaken?

mediamogul

@Rion said in Guide: Advanced Controller Mappings:

It shouldn't be a problem. I hate that the system-wide config isn't working out for you. I might pick up one of the 8Bitdo models in the near future to test with. They seem like a nice wireless option to have around.

Rion

@mediamogul

They are of great build quality. The SFC30/SNES30 models is as close to the real controller you can buy.

Thank you for all your help. I will revisit this at a later time. I will probably bugg you some more when i start mapping the individual emulators that don't have full gamepad support. 😊

Not a problem. I'm sure we'll have better luck after the controller has fully paired.

I've finally tried to use what I learned from this thread (and another one about mapping the Atari800 emulator buttons) and the wiki to my Retropie installation, but it does not seem to work.

were I've tried to map my XboxOne controller to the Atari800 emulator control keys.

I've mapped half the dpad (that is treated as an ABS event) to the main direction keys, and I've used the mapping of the Atari800 buttons from this thread:

https://retropie.org.uk/forum/topic/3651/mapping-certain-keys-from-atari800-emu-to-the-gamepad/7

It seems all OK to me, as the same Xbox One controller configuration is succesfully used in the rc.local file, but when I start the Atari800 emulator from Emulationstation, and select a game from the list, I just get the emulator menu (the one in which you can choose the cartridge type), and I cannot move the cursor using the controller.

I've made the script executable, and configured xboxdrive to run at user level.

Could anybody point me to what I'm doing wrong ?

Thanks a lot !

Hi @weirdocollector ,

Hi think the problem is the & at the end of the variable XboxOne, when the command is executed in the eval $joycommand part, it will run only the Basic XboxOne configuration in the background, and will not pass the specific command for the emulator.
The & to run the program in background is already part of the joycommand variable, so it is also not needed.

Please, try to edit the command removing & from the XboxOne variable and let us know if it's working.

MadHorse

Hi,

i would like to thank @meleu for the information you gave me about the standard output redirection and about the runcommand.info, i don't know why i never tried to open it before :).
And thank to @mediamogul for his guide, his help, and for adding the runcommand-onstart.sh to the Universal Controller Calibration & Mapping Using xboxdrv wiki page.

Thank you all.
