8bitdo Arcade Stick - Trigger Buttons are setup as Axes

rastabolino

Just wanted to say i was not trying to hijack your thread superdodge. I'm trying to help out and solve the same problem. I think not many people are using this controller yet. Hopefully we can get all the buttons working :)

The Vendor/Prod should be handled by xpad (looks like the controller tries to mimic the original Xbox 360 controllers).

Can you run the following commands

sudo dmesg -c
# unplug the controller, then plug it back again
dmesg

Can you post the output of the last dmesg command ?

Ok, I have a small update, I sincerely hope this info can help.

This morning I did the following:

made a fresh install of RetroPie 4.7.1
went into retropie setup and updated everything I could, including update all driver packages. I believe it updated the xpad driver.
connected the 8bitdo arcade stick using bluetooth. Same issue, the LT and RT buttons did not register at all...
came back to this forum and realised you probably wanted to check the controller while plugged in via usb due to the lsusb command...
plugged in via usb, went to configuration setup. The LT and RT buttons registered during setup! They show up as button 6 and button 7.

Here are the logs requested after this process in case it shows the difference . Let me know if you would like to see anything else.

@rastabolino Thank you for the info.
The log shows the controller being connected both via Bluetooth and USB. If the gamepad you configured in EmulationStation was named 8BitDo Arcade Stick, then you configured the Bluetooth part, if it was named Microsoft X-Box 360 pad, then you paired via the USB connection.

@mitu @SuperDodge

I can confirm the following:

Updating the xpad driver that comes pre-installed on 4.7.1 release fixed the problem for me for the USB connection only. All the buttons can now be assigned controls.

The Bluetooth functionality is still not there though... LT and RT are not recognized and can't be assigned. I'll start a new thread for that since it's a different issue from this thread.

I'm not getting the same results as you. I have tried updating xpad and uninstalling and reinstalling xpad. In neither case does my setup recognize the trigger buttons as buttons. It sees them as axes that go from -xxxxx to xxxxx as Axes #2 and #5.

I have not tried setting the device up over bluetooth as I want it to work over usb for reduced latency.

mitu

@superdodge Is the controller plugged in directly ? Your log shows a receiver is also connected via USB.

Have you tried to connect the controller in Switch mode ? Does is behave differently ?

@mitu said in 8bitdo Arcade Stick - Trigger Buttons are setup as Axes:

There are three ways to connect this Arcade Stick to the Pi.
#1 - Bluetooth
#2 - Hard-wired USB
#3 - An included 2.4Ghz 8bitdo USB adapter.

The battery on the device lasts longer and the latency is lower using #2 over #1.

My use case goal is to use #2 & #3 depending on whether I'm casually gaming with friends or "getting serious" lol.

I have tried and get the same results in both use case #2 and use case #3. I ran all the commands you asked for above in use case #3. I can re-run in the in use case #2 if it will help in any way.

I came here hoping there was some way to tell xpad to treat these as buttons not axes via xpad.conf, etc.

I ran jstest in switch mode and it shows all the buttons triggering on and off and several of the axes going from extreme to extreme.

xpad has a parameter (triggers_to_buttons) that does exactly that. The RetroPie setup script adds automatically this parameter when installing the driver, you can check the /etc/modprobe.d/xpad.conf configuration file to see if it's enabled.

SuperDodge

Solved although the solution is a bit odd. I'll record what I had to do here for anyone else with the same issue.

If the 8bitdo Arcade Stick is plugged in via hard wire or has the usb receiver plugged in when removing and reinstalling xpad via the Retropie Setup script then I got results where the trigger buttons were seen as axes. With nothing plugged in and repeating the same steps it behaves normally.

This makes no sense to me but I honestly don't understand how Retropie modifies the xpad install post installation so maybe it is somehow meaningful.

Regardless my 8bitdo Arcade Stick is now functioning as expected.

SuperDodge

So I lied. Just ran jstest and it appears that xpad now sees the trigger buttons as the Left Stick and Right Stick buttons. So while this allows me to physically use the buttons, I can't setup name controls where I can switch between controller types.

Is there any way to edit how xpad sees these buttons or it just is what it is?

The xpad driver is 1 source file on https://github.com/paroj/xpad, you can freely modify the sources and re-compile the driver.

If you want to re-map controls based on games, you can do so from the emulator - RetroArch allows you to have per-game input mappings, without re-configuring your controller.

I posted this in a similar thread. This workaround works flawlessly for me and doesn’t require any editing in Retropie:

Go to the 8bitdo official website, download and install the 8bitdo ultimate software on your PC or Mac, if not already done.
Plug the 8Bitdo Arcade Stick to your PC or Mac with a USB cable and make sure your selector knob is in “X” mode (top left of the 8bitdo Arcade Stick)
Start the 8bitdo Ultimate software
On the right, in the button mapping panel, beside RT, associate RS instead. Do the same for LT except choose LS.
Don’t forget to synchronize the controller (icon at the top) before disconnecting the USB cable.
Connect your 8bitdo Arcade stick to the Retropie either via a USB cable, the 2. To 4G stick or Bluetooth.
Push the start button to get to the main menu (you might need another controller or keyboard to make the selections initially).
Select “configure input”. At first, make sure your selector knob is selected to DP (middle selection) to associate D-pad up, down, left, right. This time the RT and RS buttons will work flawlessly.
