Question FFB problem with leonardo (beginner)

Hello, this is the first time I post something on this forum after hours of reading !
I made a first prototype of an ffb steering wheel using arduino leonardo and EMC lite with two BTS7960 driver for two 770 motors on a 12V power supplie, this project is very well documented so I made it quite easiliy despite the fact that I have no experience on coding. But now I have a problem and I am asking you if you could give me any advices on what to do. The steering wheel and the pedals are working very well but the ffb isn't working. I am sure of my wiring so I tried to remove a motor, I also bought two new BTS drivers but it still give nothing.
By looking on this forum I found that the cause of that may be that all the BTS drivers I bought have a GAG125 which may be not enough according to what I read on others posts.
Do you think this may be the cause or have you any other idea of what to do ? If it is, a BTS 7960 with a GAG523 would be good ?
I attached the shema I used below.
I hope someone could help me, thank you !

Please guys nobody have any idea ?
Or at least a way to look in ?
Thanks !

I am reviewing the wiring that you attached and that project is from Ai-ware which also works with arduino

The EMC has different wiring, I will give it to you so you can check it, you may find the error there. I have done both projects and I have had no problems.

Okay thanks, but I am not sure this is for thé lite version, because we cannot use any H-shifter on this one. Anyway I bought a stm32 and I bought the liscence of the pro version of EMC ultility.
Thanks again

I tried the lite version with this wiring, the difference I understood was the greater control of the ffbb and the update

I am attaching the wiring in stm32 for you to review.

Yes I git it with a video on YouTube. Thank s a lot !
And I don’t have ant Z on my rotary encoder, only A and B, have I to keep the same wiring, and let a space on the A2 pin or to put the first potentiometre ( acc. ) on A2 ?
Thanks !

And are the filtre necessary on the potentiometre, can’t we just plug the middle pin of the potentiometres on the differents A pins ?
Thanks for your help !

I believe that the filter is used to avoid noise or intermittent readings that potentiometers may have.

although I use them without a filter and it works without problem

The z index is for when you turn on the steering wheel it automatically finds the center

reviewing my notes for when you don't have the z index it doesn't connect and every time you start you have to select that the steering wheel is centered

I am attaching a manual where the procedures are indicated, I hope it helps you.

Okay great, thanks a lot !
