Some issue with Pot S2

[JoeBuster]

Hy guys, i have some issue with the S2 Pot with detent.

I would like to set some sounds tor three of the Pot positions.

- first sound at 100
- second sound at 0
- an third sound at -100

100 und -100 is not the Problem. The big problem is zero. I calibrated the Pot several times. The 100 Point is 988 µs, the zero Point ist 1478 µs and the -100 is 2012 µs.

If i turn the pot from left to right the center sound does not work - but if i turn the pot back from right to left, the center sound works, because from this direction i touch the center value of 1500 µs. The problem is that the center is not 1500 µS from both direction.

Any idea what i can do? For the function of this pot it`s not importend that the center position will fit (the pot is for gimbal use only), but for playing the center sound it is importand.

Any ideas how i can program this in the custom switch menue of the taranis / companion?

Thanks for your suggestion

Joe

In the radio setup, is the S2 set as "Pot with Detent" ?

Mike.

[JoeBuster]

Yes it is.

[Kilrah]

The pot is likely sloppy then. Can you compare with S1?

[MikeB]

Go to the ANALOG INPUTS screen. With the pot at the centre detent, what are the two values beside A6:?

@ Kilrah

S1 is not possible anymore because i changed this Pot to the six position switch

@ MikeB

A6 = turning from LEFT to RIGHT LEFT = -100 (hex 0000) // Center = -4 (hex 03CE) // RIGHT = 100 (hex 07FE)

A6 = turning from RIGHT to LEFT LEFT = -100 (hex 0000) // Center = 0 (hex 0400) // RIGHT = 100 (hex 07FE)

[MikeB]

Clearly the pot doesn't centre mechanically the same from the two different directions.

"Clearly the pot doesn't centre mechanically the same from the two different directions."

With other words, the Pot is broken and must replace?

Hy Joe
you will never reach exakt 0.000 with a Poti to select something

you can´t select an anlog poti like this one
L1 a=x s2 0

you have to select it with a small hyteresis funktion like this one
L1 a~x S2 0

or with a bigger hyteresis like this
L1 a<x S2 +5
L2 a>x S2 -5
L3 AND L1 L2

Same effekt with +/-5
L1 |a|<x S2 5
but only 1 Log Switch


the other endpoints are easyer
L4 a>x S2 97
L5 a<x S2 -97


and you can select at German "Mittelstellungspieps" for S2

or with a bigger hyteresis like this
L1 a<x S2 +5
L2 a>x S2 -5
L3 AND L1 L2

Don't you have a |a|<x in openTX?

L1 |a|<x S2 5

L1 will be ON between -5 and +5. And you use only one logical switch..
