Problem with Tomahawk Joystick

Hello, my name is Ilais and i am from Greece. I have a Tomahawk Joystick and also a usb game port adapter. When i connect to my pc (windows and linux) my joysticks works fine! But when i start the fs-uae the "right" and the "down" dows not work! I test it also to the windows and i have the same problem.

I see that it is from the emulator problem because the linux and windows on the configuration work fine.

Any help please?

Sorry for my bad English.

Do you mean that you also have the right/down problems when you use the built-in joystick tester in Windows?

It does not sound like an FS-UAE bug...

No, when i try it to windows/linux tester the joystick works fine. When i open the fs-uae then the right/down does not work.

What adapter do you have?

[s2325]

This adapter should have switches.

It is the Super Joy Box7 adapter. I try the win-uae on my windows and works fine. So the problem is at the fs-uae. The switches is ok. I am sure about that.

Try to configure the joystick in FS-UAE Launcher settings (map the "fire button" as south button, and directional movement to d-pad).

Where i can "map" the fire button? Where in setting?

[FrodeSolheim]

On "Joystick page" in FS-UAE Launcher settings, double-click on the list entry for your Tomohawk joystick (well, the entry will identify the adapter).

i found it... i do everything you say.

The problem still here! When i press the south button/up/left from the configuration and then from my joystick it is ok. When i press the down/right it says from the configuration "use joystick" i do my joystick down but nothing! The configuration file with the controller is:

[fs-uae-controller]
name = WiseGroup.,Ltd Gameport to USB Controller
platform = linux

[device]
make =
model =
type = gamepad

[sdl]
guid = 03000000250900003210000000010000
buttons = 8
hats = 1
axes = 4
balls = 0

[default]
include = universal_gamepad
axis_0_neg = dpad_left
axis_1_neg = dpad_up
button_0 = south_button

[FrodeSolheim]

And what software does it work perfectly with on Linux?

Have you tried the console program jstest? What happens if you run e.g.:

jstest /dev/input/js0

and press down or right?

I have tried it and works fine. No problem with up/down/left/right/fire

[FrodeSolheim]

I still want to know what happens. What axes/button changes you do see in jstest when pressing right, for example.

And again, have you tried other software/games on Linux?

I do not know other softwate for Ubuntu. I try winuae with wine and work fine the Joystick!

When i press right on jstest it gives me:

Axes: 0: 31721 1: 712 2: 128 3: 128 4: 0 5: 0 Buttons: 0f
Axes: 0: 348 1: 712 2: 128 3: 128 4: 0 5: 0 Buttons: 0f

Try to run fs-uae-device-helper manually:

fs-uae-device-helper --events

You should then get output like this:

{"type": "joy-axis-motion", "device": 0, "axis": 1, "state": 32767}

One line per state change. Does that seem to work? Do you get state changes when pressing right and/or down?

When i press the command i take this:
liakos@liakos:~$ fs-uae-device-helper --events

When i press up i take:
{"type": "joy-axis-motion", "device": 0, "axis": 1, "state": -32768}
{"type": "joy-axis-motion", "device": 0, "axis": 1, "state": -6218}


When i press down i take:
{"type": "joy-axis-motion", "device": 0, "axis": 1, "state": 13275}
{"type": "joy-axis-motion", "device": 0, "axis": 1, "state": -6218}


When i press right i take:
{"type": "joy-axis-motion", "device": 0, "axis": 0, "state": 14619}
{"type": "joy-axis-motion", "device": 0, "axis": 0, "state": -5882}


When i press left i take:
{"type": "joy-axis-motion", "device": 0, "axis": 0, "state": -32768}
{"type": "joy-axis-motion", "device": 0, "axis": 0, "state": -5882}

When i press button (only 1 button it has) i take:
{"type": "joy-button-down", "device": 0, "button": 0, "state": 1}
{"type": "joy-button-up", "device": 0, "button": 0, "state": 0}


Any help?

[FrodeSolheim]

Yes, I think we have found the problem here -It has to do with the state values for the axes. Joystick axis values are (in general) designed for analog joystisks, and in SDL the values range from -32768 to 32767, where 0 is neutral (Analogue joystisks will of course seldom be exactly 0 in the rest position).

You'd expect digital adapters to report -32768, 0 and 32767 for left, neutral and right, respectively. Also, since FS-UAE is designed to work with analogue sticks as well, FS-UAE accepts anything < -20000 as negative, anything between -20000 and 20000 inclusive as neutral, and > 20000 as positive.

The problem is that for your adapter, right and down results in 14619 and 13275 respectively, which FS-UAE interprets as neutral... -so an option to change the threshold would fix this. Alternatively, perhaps the joystick can be calibrated in the OS to fix the range?
