Rotary Encoder Help for A10 ILS Panel

[Kenpilot]

I'm trying to use rotary encoders for changing the ILS frequencies in my A10 simpit but apparently they aren't "sensitive" enough? One turn/click changes the frequency too many numbers so to speak. For example, it will go from 108.00 to 110.00 and skip over 109.00, unless I carefully turn the knob and leave it half way in between clicks/detents. I'm using "20 pulse" encoders. Do I need a different encoder or is there something in the arduino sketch that can be changed to make the encoder more sensitive with each turn of the knobs to speak? Thanks!

You may need to use the "two steps per detent" argument. See here:

To clarify:
Put this at the top of your code:

typedef DcsBios::RotaryEncoderT<POLL_EVERY_TIME, DcsBios::TWO_STEPS_PER_DETENT> TwoStepRotaryEncoder; // A custom rotary encoder with two quadrature steps per physical detent.

Then use "TwoStepRotaryEncoder" in place of the "DcsBios::RotaryEncoder" part of the code lines.  e,g,

TwoStepRotaryEncoder ilsKhz("ILS_KHZ", "DEC", "INC", PIN_A, PIN_B);

Awesome, thanks so much guys. I'll try this out tonight.

It worked! Thanks so much guys!! It's still a little finicky, sometimes the numbers don't change when I turn the knob and I have to turn it once or twice, but its working, I'll just be patient with it. Thanks again!!

Do you have capacitors on the signal lines?  It might help.
See attached (the dotted resistors are not required).

I don't have capacitors attached, no, but I'll certainly try it since its still acting weird sometimes. Thanks for the suggestion!

You also may use the KY-040 modules, ready made encoders including resistors and capacitors and additional switch.

They don't have the capacitors.

Those are actually the Rotary Encoders that I'm currently using, the KY-040 style. I do have the ones like the ones in No1sonuk's post. Should I use those instead with the capacitors? I guess it can't hurt to try them with the capacitors.

[No1sonuk]

You can add capacitors to what you have.

The capacitors worked and it's working perfectly. now. Thanks No1sonuk!!
