@bassman6805
i got my mapped with xboxdrv and it works fine for me. so it can be done

bassman6805

I'm hoping someone can maybe give some more detail on how to fix this. I read through the xboxdrv instructions and it seems way over my head. I don't even see the option to install the xboxdrv in the new version of retropie. Could someone look at my config file I posted and maybe tell me what to change or add?

ExarKunIv

@bassman6805

if someone can help you get it installed. ( i cant im running a older version of Pie so for me it was in the driver option in the RetoPie setup).

i can help you with getting it mapped

bassman6805

It's my understanding that the xboxdrv installed automatically now in some of the newer versions but I could be mistaken.

ExarKunIv

@bassman6805

oh, well that's cool.

let me know what you need help with when you try messing with mapping.
unless someone else has a better idea

bassman6805

Ok. Should I jump to section 3a of the guide you posted or do I need to do something else?

ExarKunIv

@bassman6805

if you have what your controller is called and what the buttons pin outs read then yes.

if you dont then you want to start from the beginning.

bassman6805

I don't know if it has a name. Here is what is in the config file.

Keyboard input, Joypad and Joyaxis will all obey the "nul" bind, which disables the bind completely,

rather than relying on a default.

input_player1_a = "z"
input_player1_b = "x"
input_player1_y = "a"
input_player1_x = "s"
input_player1_start = "enter"
input_player1_select = "escape"
input_player1_l = "q"
input_player1_r = "w"
input_player1_left = "left"
input_player1_right = "right"
input_player1_up = "down"
input_player1_down = "up"

input_player1_l2 =

input_player1_r2 =

input_player1_l3 =

input_player1_r3 =

This is also the controller I am using. It works fine for everything else.

hmmm
well for mapping you need a bit more.

you need to run this first so you can get the info that is needed

cat /proc/bus/input/devices will pull up something like this.

@bassman6805

ok good the second one is not a big deal. so no worries

the next thing we need to do is start the mapping.

as you read in the guide you will need to make a runcommand-onstart.sh and runcommand-onend.sh

for runcommand-onend.sh you just need to follow what is in the guide, that will never change.

the runcommand-onstart.sh is the one that will change, i will help you out with the start, once you play with it a little then i can point out what needs to be done to get it going

[•] is where you will enter the keycode from your post above.
--evdev-keymap KEY_#304=a is how you will need to enter it.

#!/bin/sh
sudo killall > /dev/null 2>&1 xboxdrv
/opt/retropie/supplementary/xboxdrv/bin/xboxdrv > /dev/null 2>&1 \
     --evdev /dev/input/event0 \
    --silent \
    --detach-kernel-driver \
    --force-feedback \
    --deadzone-trigger 15% \
    --deadzone 4000 \
    --mimic-xpad \
    --evdev-absmap ABS_[•]=x1,ABS_[•]=y1,ABS_[•]=x2,ABS_[•]=y2,ABS_[•]=lt,ABS_[•]=rt,ABS_[•]=dpad_x,ABS_[•]=dpad_y \
    --evdev-keymap BTN_[•]=a,BTN_[•]=b,BTN_[•]=x,BTN_[•]=y,BTN_[•]=lb,BTN_[•]=rb,BTN_[•]=tl,BTN_[•]=tr,BTN_[•]=guide,BTN_[•]=back,BTN_[•]=start \
    &

so you have a anlog joystick on your controller? or is it just buttons

bassman6805

Thanks. I will work on it this evening when I get home. The controller is in the picture. It has an analog joystick and buttons. The buttons are from a super nintendo controller board I cut up and the analog joystick is from the raspberry pi store. Here is the guide to what I made.

https://learn.adafruit.com/super-game-pi

I don't think the joystick is an actual analog movement joystick. Looks like it's just up, down, left, right.

ExarKunIv

@bassman6805

ok cool

the only think that might be a hang up will be the fact is that you do no have any ABS or anglog movement which is used for the mouse movement.

but i think it still should work with just buttons, we will cross that when the time comes. if need be we can ask the god of keymapping.

bassman6805

I completed both steps of creating the runcommand-onend.sh and runcommand-onstart.sh. Based on what I posted above for my controller layout does this look correct for the keys?

--evdev-keymap KEY_#44=a,KEY_#45=b,KEY_#31=x,KEY_#30=y,KEY_#16=lb,KEY_#17=rb,BTN_[•]=tl,BTN_[•]=tr,BTN_[•]=guide,KEY_#1=back,KEY_#28=start
&

If so, where do I assign the keys for direction? According tho the results I got they would be keys 108, 103, 105, 106.

Thanks for your help.

ExarKunIv

@bassman6805
so far it is looking good
you can remove BTN_[•]=tl,BTN_[•]=tr,BTN_[•]=guide

for your d pad it will look like this BTN_TOP2=du,BTN_PINKIE=dr,BTN_BASE=dd,BTN_BASE2=dl
replace the BTN with your key number

as for getting it to work with the mouse im still looking it to

bassman6805

When I add the directions do they go in the same line as the others?

ExarKunIv

@bassman6805

yes.

you keep everything that goes with the first part in the same line.
--evdev-keymap is for keys and buttons.

bassman6805

Here is what I have for the onstart.sh

#!/bin/sh
if [ "$1" = "scummvm" ]
then
sudo killall > /dev/null 2>&1 xboxdrv
