Hi
I have a loco decoder ( Digitrax  DH126)  with unknown loco address.  With EZ Command how do I reset CV8  to give defaults for all CVs and loco address to number 3 .   Is there a Arduino solution to use a 16x2 lcd display, to show result?

With the decoder out of locomotive (do not want to run the motor)  how do I set up wiring to achieve the reset.   Using breadboard is it  Tk A to  Red on decoder and Tk B   to blk on decoder ?  I am being a bit simplistic here, old brain.
Thankyou

You're not oversimplifying, you are making it too complex.

EZ command is not able to change any CVs at all or reset anything.  And unless you know the locomotive address, you can't even get into it to reset CV8 without putting it on a program track, which doesn't access the locomotive by address.

Executive summary:  You have to put your locomotive on the program track of some more advanced DCC system or program it on the main of the same system (only if you already know the address, which you don't).  EZ command is basically a DCC train set power source for people who don't care about CVs and stuff like that.

And, hopefully, when you took the decoder out and disconnected the wires , you marked each ones to know where to reconnect.  Especially if you did all eight of them.  If you didn't, "rewiring" will require a back feed of each circuit to identify.

I don't know anything about Arduinos. I'm too old. 😂😂😂😂😂

I find it much easier to use a PR4 connected to an EZ track terminal track with an additional straight attached. The PR4 connects to my PC via USB.  And I use JMRI.  JMRI is freeware and has a decoder programing tool "Decoder Pro".  You can read all the current decoder CV values. What is nice is you can save your decoder CV values to a file (Backup you decoder). And restore the values is something goes wrong.   

All good if you are digitally conversant.

I am not.

I keep a notebook with those same settings written down for each locomotive.

I was doing that at first, them my notebook ran out of pages!   

It's those darn sound decoders with all those features.

I think the main reason I use JMRI is because I do not like looking up CV values in a booklet and try to figure out what value that CV needs to be.  I just like have the ability to change my bell volume on the main line by sliding a volume slider with my mouse.   

BluNami does the same thing.

I do not think you can export the decoder settings to a file with the Blunami app.   I will test this.  But the Blunami app only works for Blunami decoders.  Unlike JMRI what works with almost all decoders.

Blunami's are great decoders and I believe they are the future of locomotive control.  I just wish manufactures would start to factory install them.  Hint Hint.
