joystick has only axis 4 and axis 5 how to configure for linapple?

niyoki

Hello,
I use the linapple on my Retropie (raspberry pi 3b+ with an Ultimarc ipac2 keyboard encoder ).
Ipac2 interface is emulating / encoding arcade joysticks and buttons as two gamepads (Dinput mode).
If I test with jstest under retropie command line my joystick showing six axises but if iI move joystick there is physically onl three axises are existing= axises 2, 4 and 5 (axis 0, 1 and 3 not really existing).
I can edit nano /opt/retropie/configs/apple2/linapple.conf to change or remap buttons and the axises.
But if I change the joy0axis0 = 0 to the joy0axis0 = 4 and the joy0axis1 = 1 to the joy0axis1 = 5 nothing happens.
Maybe the linapple is not listening to the joystick which has more than 4 axises?
Because if I change the joy0axis0 = 0 to the joy0axis0 = 2 its working.
Is there any solution or hints how can I solve this issue?

Kind Regards
Niyazi

The sdl1 library which Linapple uses for joystick support may not support more than 4 axis or may be mis-detecting the axis support on the encoder.

Can you install the evemu-tools package and output the result from

evemu-tools /dev/input/jsX

where /dev/input/jsX is your joystick device.

@mitu Hello, thank you for your quick answer.
I tried to install the evemu-tools.
sudo apt update
sudo apt install evemu-tools
I get this:
evemu-tools is already the newest version (2.7.0-1)
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
After that if I execute this command below:
evemu-tools /dev/input/jsX (for my case js0 or js1)
I get an error:
-bash: evemu-tools: command not found

Before I tried with jstest /dev/input/js0 or jstest /dev/input/js0 My joystik has two axises 4 and 5 , also 2 trigger buttons acting as a axis 2 and 9 buttons for home, back, start, fire etc.

Driver version is 2.1.0.
Joystick (Ultimarc I-PAC 2) has 6 axes (X, Y, Z, Rz, Hat0X, Hat0Y)
and 16 buttons (Trigger, ThumbBtn, ThumbBtn2, TopBtn, TopBtn2, PinkieBtn, BaseBtn, BaseBtn2, BaseBtn3, BaseBtn4, BaseBtn5, BaseBtn6, ?, ?, ?, BtnDead).
Testing ... (interrupt to exit)

Sorry, the command is

sudo evemu-describe /dev/input/eventX

where /dev/input/eventX is the file corresponding to the joystick. You can check which eventX file is tied to the joystick by running

udevadm info /dev/input/event*

@mitu Hi, I tried to run both commands :
for the udevadm info /dev/input/event* command
https://pastebin.com/vJwd5FXB

and for the sudo evemu-describe /dev/input/event0 command
https://pastebin.com/E10sE2A3

@niyoki You can use pastebin.com if the text is too long.

The output looks ok.
You can check with sdl-jstest from https://github.com/Grumbel/sdl-jstest to see if the axis you want to configure work with sdl1. This would rule out any issue with sdl1 not detecting properly the axis.

@mitu I installed (it was not easy for the beginners like me) the sdl-jstest. Than I used this command: jstest-sdl --test 0 also jstest-sdl --test 1

Now my Joystick reacting only to axis2 (left and right trigger buttons) input and has 1 hat switch (using axis4 and axis5)

... and has 1 hat switch (using axis4 and axis5)

So it looks like axis4/5 are not considered as an analog control, but as a Hat - probably that's why linapple doesn't use them.
