[Can an axis change its function depending on a button state?]

Ooops, I must apologize to everyone for being a moron, I finally detected that I had not removed the default FSX joystick axis assignments, so of course it conflicted with the FSUIPC set-up !!

 

It works perfectly now, again sorry for the useless post !!

 

Best regards...

[Can an axis change its function depending on a button state?]

Actually, I may not need to. I thought of a very simple way to do this sort of thing, very flexibly. First, make sure your FSUIPC installation is up to date -- latest versions are supplied in the Download Links subforum.

Then save the following as, say, "multiaxis.lua" in your FS Modules folder:

 

function applyaxis(val)
   cntrl = ipc.readUD(0x66c0)
   ipc.control(cntrl,val)
end

event.param("applyaxis")

and edit the FSUIPC INI file, adding this section:

[Auto]

1=Lua multiaxis

(if you already have an [Auto] section, add the line with the next available number).

Now run FS. Go to FSUIPC axis assignments and assign the axis you want to switch as an "FS control", choosing this one from the drop-down list:

Luavalue multiaxis

Then go to the Buttons assignments and assign the buttons you want to use for selecting the axis use, on the right-hand side, as follows:

Offset dword set, with Offsetx66c0 and the Parameter set to the value of the FS or FSUIPC control you want the axis to send.

The controls are listed in a List installed in your FSUIPC Documents folder, in the Modules folder. You can use any control, but obviously only axis controls make much sense. Those are all either named "Axis ..." or end in "set". There are more controls, added by FSUIPC, and listed in the FSUIPC Advanced User's guide. BUT the ones you really want, for the purposes you chose, are currently only published in the "Changes" document included with the recent FSUIPC updates (see Download Links). They are numbered 64101 to 64144, and the ones you want are:

64136 steering tiller

64123 flaps

64122 spoilers/speed brakes

Once you've done all this, exit to FS, select a mode using the buttons/switches you assigned above, then go into FSUIPC joystick calibrations and calibrate the axis for that selection. You'll need to exit to change the mode to calibrate each separately -- FSUIPC doesn't obey the button presses when in the options (for pretty obvious reasons).

Note that this technique is extensible for any number of different uses for the same axis and, by using different offsets (66C4 is the next -- the range 66C0 to 66FF is free for users, giving 16 possible DWORDs to use) and renamed versions of "multiaxis.lua", can be applied to any and all axes.

I've tested all this with FSUIPC 4.754 and FSX. Have fun!

Hi all,

 

I am trying to use the lua above as proposed by Pete, however with a slightly different objective : I am using a Microsoft Sidewinder FF2 joystick, and I would like to achieve the following :

- "Normal" mode : "S" axis is used for throttle, as per default assignement

- "Secondary mode" : using joystick button #2, I want to change the axis assignement so that the throttle axis becomes the prop pitch axis

 

I am using the default Baron with a specific profile to test.

 

I have installed the above lua and followed pete's process above, except I have assigned "Offset dword set", with Offset x66c0 to Button #2, and the Parameter set to "65765" which is listed as Prop pitch axis

 

However, I don't understand the calibration part, and basically nothing happens after I have pressed button #2 once : when I move the axis it still commands throttle...

 

I am sure I am missing something as I am new to lua usage. Maybe something very basic, like the way button #2 is programmed : should it be assigned to "offset dword set x066c0" only when pressed or should I do something else, like "control to repeat while held" or another control when released ?

 

I have FSUIPC registered v4.934

 

Any help appreciated !

 

Best regards
