A10 Yaw Trim Pot W/DCS Bios Not Working

[Kenpilot]

Hey guys. I can't get my home cockpit yaw trim pot to work for some reason. I'm using DCS Bios, Arduino Mega and a 10k Pot. I have the Pot connected to the Mega using a 5v pin, GND pin, and one of the Analog pins. I also copied the coding for the yaw trim from DCS Bios. It's not working at all, but the rest of the switches on my panel are. Yes, I've double checked all the connections, etc. Any idea what I'm doing wrong or might be the issue? Would a rotary encoder be better? Thanks!

Which version of DCS-BIOS are you using, and what code line?

I'm using Version V.0.10.0+64

Code: DcsBios::PotentiometerEWMA<5, 128, 5> saspYawTrim("SASP_YAW_TRIM", PIN)

probably not much help, but my DCSBIOS-based SAS panel and the Yaw trim are working with the exact line of code you used. Or at least it was working before the latest patch, I didn't try it with the most recent open beta version yet. so i'd say keep troubleshooting, I assume you did replace the PIN in your code to the actual analog input .

lol I did, but a very good question! Thanks for the response!

OK.  That's the "Hub" version that's no longer supported by its original developer.  I'm surprised it works at all now.
You should switch to the "Skunkworks" fork (formerly called the Flightpanels Fork).  That's actively maintained and updated.

Well damn. Ok, thanks for the heads up!! Now I just hope when I change over to this newer DCS Bios, everything still works! lol I'll give it a shot. Thanks!!

I downloaded and installed everything and the trim still isn't working correctly. I tried a different analog input on the arduino and tried a different arduino, still no luck. When I turn the knob, it reacts in certain positions, but it's very sensitive and doesn't turn the correct way and if I turn it all the way, the entire arduino disconnects and it doesn't work anymore, I have to close DCS out and restart it. It's very strange. Could it be the potentiometer I'm using? Should I try a Rotary Encoder? Thanks!

Hi.

I am checking the setup tab and I can't see the yaw trim as an axis, so I can't see the use of a pot. I'd rather switha to a rotary encoder and bind it as key inputs.

Saludos.

I'll try that, thanks!!

The Rotary Encoder did it! I have it working now. I'm also running the new DCS Bios. Thanks for all the help guys!! 

[Kenpilot]

My rotary encoder was working fine and all of a sudden my rotary encoder stopped reacting normally. When I turn the knob left or right, doesn't matter how much I turn it, the yaw trim in the game just bounces back and forth a small distance. I replaced the encoder and checked the wiring and nothing helped. Any ideas? I tried re-uploading the arduino sketch and that didn't help either.

Do you have capacitors on the rotary encoder?

I don't, as it was working fine without them, but I'll go ahead and wire them in and see if that helps. Thanks!!

[Kenpilot]

Wired the capacitors and it fixed the issue, BUT, now I'm having the same issue as my HSI Course knob, where each turn to a detent, turns the knob too far, too many pulses with each turn, so I can't fine tune the yaw trim. Any ideas?
