Assign an axis movement to a button action

[jauno]

Hello everybody.

I'am using FSUIPC 4.955

The background is that I would like to use the Saitek Cessna Trim Wheels together with PMDG 737 NGX in FSX. Unfortunately the trim wheels are incompatible with PMDG cause PMDG uses another way to manage the trim wheel else than FSX GA.

I did not found any solution or tweak to resolve this problem.

My idea is to convert the axis change of the trim wheel into the corresponding button command of FSX, NUMPAD 1 or NUMPAD 7 for lever trim up/down.

How could I realize that with FSUIPC?

Thanks for help

Sorry, that is well out of date. The supported version is 4.966c. Please update.

Use the right-hand side of the Axis assignments tab as explained in the user manual. 

Don't assigned to keypresses though unless they are unique to the add-on. Use the FS controls to which those key presses are assigned -- Elev Trim Up and Elev Trim Dn.

This is right. But this works only with FSX airplanes and not within PMDG panes because PMDG doesn't use the FS commands for elevator trimming but an own algorithm. However the keyboard commands work. So the idea to work with the keyboard commands.

PMDG normally provide a heap of "custom controls", as listed in the .h file withing the SDK subfolder of the installation. Any of those can be used in FSUIPC assignments by selecting <custom control> and providing the control number.

I found the value of the PDMG custom control (=70310) for elevator trim as well as the parameters for <trim up> (=16384) and <trim down> (=8192)

At right hand side of axis assignment I can only send a control while entering or exiting a range not while moving in a range. But how can I send a control every time when I turn the trim wheel (up/down) within the range.

At left hand side I can only send axis values to an offset but I can't send controls with parameters as I want it to do.

Is there a way to realize this?

Well, unless you can get a similar effect by using all 10 ranges accommodated, the only way is to use a Lua plug in,. A simple one which keeps the previous value in a Global (via ipc.set) and which checks ehether the new one is higher or lower would do the job: just assign it to your axis using the normal left-hand side assignment. 

The Lua would receive the axis value in ipcPARAM, so it would look like this

prev = ipc.get("MyTrim")
if prev ~= nil and prev ~= ipcPARAM then
   if ipcPARAM > prev then ipc.control(70310, 16384)
   else ipc.control(70310,8192) end
end
ipc.set("MyTrim", ipcPARAM)

Try that. Save it into the Modules folder as, say, "mytrim.lua". The run the sim, then in Axis assignments assign your trimmer to "Lua mytrim".

Test it. Check the FSUIPC4.log afterwards in case I've made a mistake  (sorry, haven't got time to test it here at present).
