Assign two Axes for the same function

[dabu]

Hi Pete

I have a question; I couldn't find the Answer in the forum. I started to build my home cockpit (Boeing 737 NG). I am building the flight controls myself. I have a joystick card which recognizes 6 axes. For the aileron I am using two potentiometers (FO and Captain Side). This means I am using two axes for the same function. Is it possible to assign with the FSUPIC-Module the same function twice (two axes on one joystick-card)? Or is it only possible if the two axes are on separate cards (recognized as two joysticks)? The input would go directly over FSUPIC (deleting axes in FS2004). Thanks for answering.

Well one answer is in the documentation supplied with FSUIPC.

Yes, you can assign more than one axis directly to the same FSUIPC "direct" function. But there's only one place you can calibrate, so you need to make sure the two are not completely unlike each other, and you may need to calibrate with a bigger "dead" zone at each extreme and a larger centre part too, where that applies.

Note that by doing it this way the last change in either axis will move the control, so if either axis suffers from jitter, you will likely get very variable results. The only way around this, using this method, is to make sure the currently unused axis is "parked" in one of the dead zones -- i.e. centre or min or max, hence the need for possibly more generous zones for these.

The way which is generally recommended, but which means either assigning axes in FS, or at least not direct to FSUIPC calibration, is described in the section called "Multiple joysticks" in the Advanced User's document. This is a bit better in that the most extreme value of the multiple inputs is the one which "wins", rather than the last one which changed (or jittered).
