Try pasting the command above the line # Print the IP address.

Mayki

No change. No Xbox gamepad.

mediamogul

@Mayki

There's a conflict with the other command in the file that's printing the IP address. I'm not sure how to make them coexist, but the xboxdrv command itself should run without the other.

Mayki

Delete the command in the file that's printing the IP address to rc.local, restart.

Go ahead and past the contents of the newly modified rc.local.

At this point, I'm starting to suspect poltergeists ;). Let's try reformatting the command to:

sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv --evdev /dev/input/event2 --silent --detach-kernel-driver --force-feedback --deadzone-trigger 15% --deadzone 4000 --mimic-xpad --dpad-as-button --evdev-absmap ABS_X=x1,ABS_Y=y1,ABS_Z=x2,ABS_RZ=y2,ABS_#48=lt,ABS_#49=rt --evdev-keymap KEY_#302=a,KEY_#301=b,BTN_DEAD=x,KEY_#300=y,BTN_THUMB=tl,BTN_THUMB2=tr,BTN_BASE5=lb,BTN_BASE6=rb,BTN_TRIGGER=back,KEY_#720=guide,BTN_TOP=start,BTN_TOP2=du,BTN_PINKIE=dr,BTN_BASE=dd,BTN_BASE2=dl --calibration x1=-32767:0:32767,y1=-32767:0:32767,x2=-32767:0:32767,y2=-32767:0:32767 &

Mayki

Such an idea.
If Sony gamepad connected via bluetooth and I enter the SSH command:

sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv \
	--evdev /dev/input/event2 \
	--silent \
	--detach-kernel-driver \
	--force-feedback \
	--deadzone-trigger 15% \
	--deadzone 4000 \
	--mimic-xpad \
	--dpad-as-button \
	--evdev-absmap ABS_X=x1,ABS_Y=y1,ABS_Z=x2,ABS_RZ=y2,ABS_#48=lt,ABS_#49=rt \
	--evdev-keymap KEY_#302=a,KEY_#301=b,BTN_DEAD=x,KEY_#300=y,BTN_THUMB=tl,BTN_THUMB2=tr,BTN_BASE5=lb,BTN_BASE6=rb,BTN_TRIGGER=back,KEY_#720=guide,BTN_TOP=start,BTN_TOP2=du,BTN_PINKIE=dr,BTN_BASE=dd,BTN_BASE2=dl \
	--calibration x1=-32767:0:32767,y1=-32767:0:32767,x2=-32767:0:32767,y2=-32767:0:32767

output is this:

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

Press Ctrl-C to quit

Unless Sony gamepad connected via bluetooth and I enter the SSH command output is this:

pi@retropie:~ $ sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv \

The rc.local It starts with the system, gamepad is not yet connected.
May not be gamepad startup already connected via cable necessary?

mediamogul

@Mayki

Ah... nice! OK, There's a command to force Bluetooth to load and pair known devices that can be added before the xboxdrv command. From memory I believe it's called 'modprobe' or something like that. I'll be more than happy to help you out with it, but to be honest, I'm starting to fade and should get some sleep. I'll look into it further after a few ZZZs, but feel free to read ahead. I'm curious about this myself and I remember thinking that this could potentially be a problem with Bluetooth as the system starts.

Mayki

It's as if Sony gamepad connected via a cable already at system startup, log on as an X-Box gamepad.

XBOX

If Sony gamepad connects to the system startup via Bluetooth, so the X-Box driver not lead.

mediamogul

@Mayki

With any luck, forcing Bluetooth to load and pair known devices at startup should correct the problem. The fact that it connects via USB at startup is a good sign.

Mayki

O.K. Thank you so much for your help in solving the problem.

mediamogul

@Mayki

Not a problem. I get the benefit of learning from this too. Try adding rfcomm bind 0 XX:XX:XX:XX:XX:XX 1 in a line just before the xboxdrv command in rc.local, substituting your controller's Blutooth address for "XX:XX:XX:XX:XX:XX" of course.

Mayki

This is probably not the right way, it wanted the script to be run after connecting the PS3 gamepad via bluetooth. They must be written in rc.local?
Gamepad itself does not connect If you press the PS button.

Idea:

1 - Start Retropie
2 - Press PS button on gamepad (gamepad connected as PS3)
3 - Run script (with similar content) :

sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv \
	--evdev /dev/input/event2 \
	--silent \
	--detach-kernel-driver \
	--force-feedback \
	--deadzone-trigger 15% \
	--deadzone 4000 \
	--mimic-xpad \
	--dpad-as-button \
	--evdev-absmap ABS_X=x1,ABS_Y=y1,ABS_Z=x2,ABS_RZ=y2,ABS_#48=lt,ABS_#49=rt \
	--evdev-keymap KEY_#302=a,KEY_#301=b,BTN_DEAD=x,KEY_#300=y,BTN_THUMB=tl,BTN_THUMB2=tr,BTN_BASE5=lb,BTN_BASE6=rb,BTN_TRIGGER=back,KEY_#720=guide,BTN_TOP=start,BTN_TOP2=du,BTN_PINKIE=dr,BTN_BASE=dd,BTN_BASE2=dl \
	--calibration x1=-32767:0:32767,y1=-32767:0:32767,x2=-32767:0:32767,y2=-32767:0:32767

4 - PS3 gamepad via bluetooth logs on as MICROSOFT X-BOX 360 PAD

Is it real?

Rion

@BuZz Having this kind of functionality build in to the Retropie setup would be very useful.

mediamogul

@Mayki

Your idea should work. Give it a try and see how it goes.

Mayki

@mediamogul said in Guide: Advanced Controller Mappings:
------------------------------------------------------------------------------
The foundation has been laid. Controller's have been fine-tuned. Next, we'll take a look at how to map keyboard keys and mouse movements to a controller's analog sticks and buttons for use in emulators that lack native controller support and how to launch and maintain multiple mappings accordingly.
------------------------------------------------------------------------------
Hi, what's the continuation of the manual? I can hardly wait ... :-)

mediamogul

@Mayki

It's coming. There are just a few things I want to test to make the multiple mappings as easy as possible.

@mediamogul Hi! Your guide is very interesting.
I was wondering if it is possible to map the configuration you are describing outside of /etc/rc.local and instead use a .cfg file like one described in the Retropie Wiki . I would like to be able to switch between left-analog and D-Pad easily, and it seams to be a right way to do it. Any clue? Thanks again!
