Sony DualShock 3 - call for testers: "sixaxis" script module

Silent

@psyke83 So I tested both Moonlight and Steam Link:

Moonlight: Triggers register as 100% press upon the slightest press.
Steam Link: Behaviour was same, but in Steam Link app I ran Setup Controller again and reconfigured the controller. After that, it works as expected!

Do you know where Moonlight and Steam Link keep their mappings? I want to try to sync them to see if I can get triggers to work in Moonlight too.

For both my test case was DiRT Rally - a XInput game, in which you can see % press of an axis in Controls screen, so it's a reliable method of checking.

I might be wrong, but take a look at /etc/modprobe.d/xpad.conf
If "triggers_to_buttons" is set to 1, change the value to 0, reboot and see if it makes any difference in moonlight.

how would one install said driver? I would like to test it.

You need to be relatively comfortable with using the command-line to test.

These commands will enable the PR branch:
cd RetroPie-Setup
git remote add psyke83 https://github.com/psyke83/RetroPie-Setup
git fetch psyke83
git checkout sixaxis
Make sure to go back to the official branch after testing the PR! Uninstall sixaxis from the menu, then:
cd RetroPie-Setup
git checkout master
It's been confirmed that both official and Shanwan controllers are working. I need someone with a Gasia branded pad to test.

I had problems with the default Driver for Dualshock3. In my case, the problem was about the use of a 8bitdo controller with the dualshock. After the dualshock configuration, the 8bitdo is deconfigured, change the driver and it didn't work when the dualshock was on. This solution solved my problem.

There was a problem with the RetroPie bluetooth menu script, but it was fixed in a commit separate from the PR. If you rebased the PR against latest master it would have been fixed.

See the readme here: https://github.com/gabomdq/SDL_GameControllerDB

Steam Link on Pi stores its bootstrapped binaries in /home/pi/.local/share/SteamLink/ and configuration in /home/pi/.local/share/Valve Corporation/SteamLink/, so the latter is a possible location to look for mappings.

Silent

@psyke83 That was helpful, thank you! I fished out my configuration and applied it to Moonlight and it all works like a charm.

Update:
Mapping from @psyke83 didn't work for me, but this one did:
050000004c0500006802000000800000,PS3 Controller,platform:Linux,a:b0,b:b1,x:b3,y:b2,back:b8,guide:b10,start:b9,leftstick:b11,rightstick:b12,leftshoulder:b4,rightshoulder:b5,dpup:b13,dpdown:b14,dpleft:b15,dpright:b16,leftx:a0,lefty:a1,rightx:a3,righty:a4,lefttrigger:a2,righttrigger:a5,

(notice how GUIDs are slightly different)

With this, triggers are pressure sensitive without the need to change triggers_to_buttons.

However, when playtesting I encountered a problem - I was streaming via Moonlight and around 10 minute mark my controller disconnected! Was it a coincidence or a bug in idle timeout script? I was using triggers, left analog stick and face buttons - so the possibility of idle script only reacting to eg. face buttons is out of question.

Also, does this driver allow reporting battery level somehow? One last issue I have with using DS3 on pi is that I am unable to tell when the battery is running low.

Where did you find that particular mapping? Perhaps I can make the Moonlight scriptmodule to grab gamecontrollerdb.txt files from a more up-to-date source instead of the included one from Moonlight.

Another (better) alternative would be if you can submit your updated controller entry to the upstream maintainer of gamecontrollerdb.txt here: https://github.com/gabomdq/SDL_GameControllerDB

I want to work on this in close future and already have some ideas drafted. I just need to find some good spare time to develop them. Also I have to finish the last details on the Moonlight scriptmodule :)

Silent

@hhromic That's the mapping I created from Steam Link app on rpi. Also, it looks like an identical mapping is already present in the database, so no need to submit anything new =)

Also, what file does this version of Moonlight read entries from? From the one in /usr/local/ or the one in scriptmodule directory?

If Moonlight is using an up to date sdl2, it would be very neat if your scriptmodule could grab mappings from this repository instead!

The mapping in the database for your same GUID is not the same as the one you provided. from SteamLink. The differences are clearly stating the triggers being regarded as analog instead of buttons:

 guide:b10
 leftshoulder:b4
 leftstick:b11
-lefttrigger:b6
+lefttrigger:a2
 leftx:a0
 lefty:a1
 platform:Linux
 PS3 Controller
 rightshoulder:b5
 rightstick:b12
-righttrigger:b7
+righttrigger:a5
 rightx:a3
 righty:a4
 start:b9

Also, what file does this version of Moonlight read entries from?

I made the scriptmodule to use the database included with Moonlight, which gets installed in the scriptmodule directory (/opt/retropie/supplementary/moonlight).

If Moonlight is using an up to date sdl2, it would be very neat if your scriptmodule could grab mappings from this repository instead!

Moonlight uses the system-instaled SDL2 lib when building and @irtimmer regularly keeps the database in sync with that repository. I will think about pulling directly instead.

Btw, more Moonlight-specific discussion should be made in its topic :)

That's right... and my post was intended to encourage others to check their own GUID. I've checked @Silent's, and the version of the db that's compiled into the current version of SDL2 built by RetroPie does use the digital buttons for this controller, unfortunately. In fact, at a quick glance, there are at least 16 PS3 variations that use the digital button mappings:

$ git grep "lefttrigger:b6" | grep "righttrigger:b7" | grep "PS3" -c
16

It might be a good idea to submit a patch to upstream SDL2 for your own GUID so that future releases work out of the box. I'm a bit hesitant to send a patch for all 16+ en masse, considering that I can't tell which GUIDs are clones that may possibly have malfunctioning analog triggers, etc.

Silent

@psyke83 Sure, I intend to do that, and also check with both my pads in case they have different GUIDs (which they may, considering both are legit but one is considerably newer than the other). I am not yet sure how to send patches to SDL yet though, so will need to look that up.

Also, this potentially important info seems to have gotten lost between the mappings talk:

I've been trying to get this working on Odroid XU4 (ubuntu with 3.10 kernel).

But not having any luck with both official or Shanwan controllers. I upgraded bluez manually to 5.48 but that didn't help either.

Anyone know if it's ever likely to work on a kernel so old before I continue trying?

Would it be possible to dynamically change the configuration per game. For example you might want to configure pacman limited to 4 way movement or allow for analog triggers for acceleration and braking in racing games but digital in most.

This can, sort of, be done by using the xboxdrv and tearing down and restarting it on a per emulator / per game basis. This doesn't really scale.

What I'm thinking would be much better is if the driver could be load once but accept configuration changes.

Thoughts?

You can specify a controller configuration via a hint in SDL2: https://wiki.libsdl.org/SDL_HINT_GAMECONTROLLERCONFIG

IIRC, hints can also be specified as an environment variable if you omit the _HINT part, so this could be a way to do it. I'm not sure if this can only append new entries or if it'll actually override an existing GUID entry.

@psyke83 That would be awesome!

I am not convinced I understand the flow of pairing DS3's via Bluetooth. Here now it went for me now, after I restored pre-sixaxis image from a backup, updated emulationstation and retropie-setup and then applied an updated sixaxis branch:

Installation went without any issues
For the first gamepad, during "Register Bluetooth Devices" process there was no mention of DualShock 3 (just "Searching..."), and I had to manually pick a pairing mode after DS3 was detected. I don't recall having to do that before I rolled back - is it because back then custombluez was being installed?
For the second gamepad, I am seeing the notice about DS3 (plug/unplug/replug), but I don't know how long am I expected to wait and sit idle on this screen. Feels like eternity, but it eventually did switch screens.

Also, I noticed bluez showed for update - a version newer than 5.48 was included officially into Stretch now maybe?
EDIT:
bluetoothd -v actually shows 5.43... not sure what did it show before the update.

@Silent For me with official dual shock 3's it just says Searching.... and I paired 5 controllers in a row without the screen changing... eventually it times out and I see that they are all in fact paired. I believe I had to plug in the cable, unplug the cable, plug it back in and press the playstation button for it to light up a controller number LED... as soon as it does that you're good.

I didn't worry too much about it because I only had to do it once, but it would be nice if that searching screen had a way to cancel - if you hit CTRL-C it jumps back to emulationstation, but if you go back in to bluetooth it will still be searching (usually times out after that).

There's some variance in the behaviour of the controller (and version of Bluez). In the older version of Bluez, if an unpaired controller in scanning mode (flashing LEDs) is connected via USB, it won't bind to the connection unless you press the PS button.

A commit has been applied to clarify the message and ensure that the "Searching..." part no longer has the possibility of hanging infinitely. Make sure to update your script so it includes this commit: https://github.com/RetroPie/RetroPie-Setup/commit/6ce74e997efa2a6109b5db8884ce8f7e2032f5f0

Another issue that's not entirely clear for end-users is that once you've successfully initiated the registration via USB cable connect, it's not necessary to choose a security mode on the next page (as the controller is already registered, and choosing any option will only cause an error). I'd like to clean that up, but I first need to ensure that the existing changes to the script haven't caused regressions for other BT peripherals.

See my reply to @edge3000, but to clarify some more:

You're correct that previously it wasn't necessary to choose a security mode. We had to revert that functionality due to a regression with other BT peripherals. I may re-introduce a better fix for this, but only after we've confirmed that no other regressions are outstanding. For now, you can just cancel out of that menu (as none of those options apply, and your device will already be registered).
The "DualShock" text is displayed only if the hid-sony kernel driver is loaded. So if you didn't plug a controller in via USB before running the script, you won't see the text (but the script will still successfuly set up registration via USB cable connect regardless of whether the text was shown).
I just checked, and there have been no recent updates to the system BlueZ packages. Official controllers and the RetroPie scripts should work fine with the existing version, so don't install the new packages via custombluez unnecessarily.

edge3000

@psyke83 Thanks that should make pairing easier!

Are your previous fixes/changes from the sixaxis PR added to the main branch yet? I'm looking forward to the day I can move back to main. My next steps are to redo all my remaps then I should be able to complete my current build.
