Automatic cursor movement in runcommand

mitu

It looks like the joystick is interpreted by joy2key as being pressed NW, that's why the constant movement being translated to key presses.

If you use jstest to see what values are produced by the gamepad's joystick, what values do you get for the axis when the stick is centered ?

The output doesn't stop, when I disconnect the adaper.

This may be a bug, the event queue doesn't get cleared when the joystick is disconnected.

There is no such unintended input in emulationstation, Kodi or within the games.

Is this joystick actually configured in EmulationStation ? Looking at the detected configuration, it wouldn't be mapped in EmulationStation's input dialog.

If you're able to compile sdl2-jstest and run it with just the C64 joystick connected, that would help understand what events are received and processed by joy2key. You can run it with

sdl2-jstest -e 0

and just paste the output (without using the joystick or pressing the button on it).

To install it, just run

git clone --recursive https://github.com/Grumbel/sdl-jstest
cd sdl-jstest
cmake .
make

I thought, it was configured in emulationstation. But it wasn't any more. So I configured it again. The result is some short up/left movement in emulationstation after connecting the adapter. But then it stops an everything behaves normal. When it is connected on startup, I don't register anything strange in emulationstation.

I remember a similar issue - joystick starts with NW pressed (see here or here). That's why they drift when you're connecting them in ES. You don't get any spurious movements if they're already connected because any input is discarded during start-up, while the splash screen is shown.

I'd be interested in the sdl2-jstest output, we may be able to implement a solution or workaround, though to be honest we might as well disable any gamepad that doesn't have 2 buttons, since you'd not be able to use it in the Runcommand menu.

Thank you for the test, this confirms what we've been seeing so far. It looks like the joystick has 2 movements added during initialisation (up/left) that don't get reset.

 SDL_JOYAXISMOTION: joystick: 0 axis: 0 value: 0
 SDL_JOYAXISMOTION: joystick: 0 axis: 0 value: -32768
 SDL_JOYAXISMOTION: joystick: 0 axis: 1 value: 0
 SDL_JOYAXISMOTION: joystick: 0 axis: 1 value: -32768

If you press down, does the 1 axis go to 0 or 32768 ?

MiK

@mitu Additional info:
There is no real joystick connected to the adapter at the moment.
If I connect the adapter to my windows system, I don't see any movement.
Perhaps this NW-"drift" is only present in init phase of the adapter.

Disabling this controller for joy2key would be fine.

If I press down direct after init I get:

SDL_JOYAXISMOTION: joystick: 0 axis: 0 value: 0
SDL_JOYAXISMOTION: joystick: 0 axis: 1 value: 32767

After releasing I get:

SDL_JOYAXISMOTION: joystick: 0 axis: 1 value: 0

If it actually has 2 buttons, then it would be able to fully operate the runcommand menus (1 button is enough for most actions anyway). I'll think of something and may have an updated version you could test in a day.

The adapter supports two joysticks. Each joystick has one button.

But the driver in RetroPie doesn't support the button of the second joystick at all. sdl2-jstest shows that the axis of the second joystick results in the same values as the first joystick. In both cases it says "joystick: 0".

One more information, I forgot: This problem wasn't there in older versions. It appeared in one of the last updates. Unfortunately I can't say which update, because I used only Kodi in the last months an didn't try to start a game.

Probably because joy2key was updated at the end of June and the new version uses now SDL2 under the hood.
I have a tentative fix for this class of problems. Can you repeat the test from yesterday, but with [this version] of joy2key:

wget https://raw.githubusercontent.com/cmitu/RetroPie-Setup/99fb97f5aef306f522850c6ebeea0117c2c6dd48/scriptmodules/admin/joy2key/joy2key_sdl.py

python3 joy2key_sdl.py kcub1 kcuf1 kcuu1 kcud1 0x0a 0x20 0x1b 0x00 kpp knp -d

You should see the connected devices and any inputs from your gamepad(s). You can try with both controllers connected and see if the inputs are correctly registered.

MiK

@mitu I will try later in the evening.
I'm not very familiar with python, but shouldn't there be the file name in the second line?

Yes, I forgot to add it. Should be fine now, thanks for noticing.

The fix seems to work. After starting the script, I only get:

Moving the joystick and pressing the buttons on the gamepad results in the corresponding outputs.

Thank you for testing and reporting the problem.
We'll add the fixes to the the RetroPie version, so one of the next updates will have the new joy2key version.

Thanks for your quick response and for your work on the fix.

How could I try the fixed version in the real environment (runcommand, RetroPie-Setup)?

mitu

@mik Just copy the .py file to /opt/retropie/admin/joy2key, overwriting the existing file, and it should be used instead for all menus.

EDIT: actually, just update your RetroPie-Setup script, the fixed version should be now included.

MiK

@mitu Sorry for the late reply: Everything works fine in runcommand and RetroPie-Setup with your new version.
