Analogue sticks

[jotego]

I am trying to add support for analogue sticks to use in the Forgotten Worlds arcade. I was thinking of moving the character using the d-pad and then rotating him with the analogue stick. But I see that MiST actually links both the d-pad and the analogue stick so I receive inputs for both at the same time. I tried connecting a dual analogue stick game pad but the second stick doesn't seem to be read.

On top of that, Forgotten Worlds is a two player game, so I actually need to do the same for the second character.

I can edit the user_io module provided the firmware already supports this. But does it? And how?

Thank you

The firmware sends the digital joystick events as analogue ones, too (mapping to min-max values). If I understand you correctly, this is unwanted?

[jotego]

Yes, it is unwanted. Some game pads have a button to produce this effect so if we remove that in the firmware I guess users who like that can still enable it in their gamepads. Is it possible to read the second stick?

Even digital Joysticks send "analogue like" signals over USB. So the firmware cannot distinguish between them. E.g. where a analogue joystick sends all values from -32768 to 32767 a digital one would only send -32768, 0 or 32767. But the firmware cannot know beforehand if the joystick will use the whole possible signal range or only three values.

True. And I think it's no problem. You can use joystick_0 or joystick_analog_0 for controller0, and joystick_1 or joystick_analog_1 for controller 1 (or vica-versa, as controller numbers are swapped by default). You can decide if you need digital or analogue values. Probably Jose's problem is that only one of the controllers is recognized on a dual-controller pad. That's something with the USB HID handling, which I don't know much about. The linking of the D-pad and analogue part probably done in the controller itself. Or are they separate controls in Windows for example?

[jotego]

Yes, even if the left analog stick and the d-pad are linked, that's fine if I can use the right analog stick.

Well, that would need checking the USB part, but I don't have such controller to test with. I suspect the two parts are multiplexed somehow, but I don't know how it's done.
