Rotary encoders

[eossim]

Hello,

Is there a way in the FSUIPC.ini file to make a value change by higher steps when an encoder is rotated fast and by one step

when it is rotated slowly ?

I have a 16 pulses/revolution encoder connected to a BU836 interface card and I want to drive a VOR OBI.

To make a full 360° dial rotation it takes 360/16 = 22,5 rotations wich is way too long (assuming no pulse is lost wich is of course not the case)

Any idea or hint ?

Thanks,

Cedric

With most encoders that happens naturally because they send pulses faster when turned faster and slower when turned slower.

First you should make sure you program both the "press" and "release", which will give you twice as many operations -- two per complete pulse.

Second, don't turn the knob the long way. 180 degrees is the most you ever need to turn it.

Those two alone reduces it to less than 5 turns max.

Third, adjust the PollInterval, as described in the FSUIPC Advanced User's document, where it specifically mentions rotary encoders. Then you should miss few if any pulses.
