    ok soo i am still panning hard to get myself a DD wheel with what i have because i cannot wait to next year to get the 130st servo motor and drive .

    currently what i had was a g27 and dfgt pro,and they both died. the g27 encoder still works as what i'm about to discuss is maybe a ffb plan to the future.

    HardWare:

    1 x Thanos TDD micro aasd 15 controller
    3 x bts 7960 motor drivers
    1 x arduino Rev3 uno
    4 x wheelchair motors (excluding the two logitech wheels )


    i managed to connect the g27 encoder with motor to the tdd board the help of a momo opto LABELED wiring diagram.(encder wiring)
    ENC A (on tdd micro board)= A White(on g27 encoder)
    ENC B (on tdd micro board)=B Black(on g27 encoder)
    5V (on tdd micro board)= 5V Green(on g27 encoder)
    GNF (on tdd micro board)=Grn Yellow(on g27 encoder)
    And what happend was i got actual game input. the wheel goes left and right when i rotate the motor.

    So my whole next idea was, Can i use a bts7960 motor drive or 2 and connect the g27 motors + encoder to have the ffb enabled. (using the DB25 wiring) (i will include images hopefully its clear or u get what i mean). If so could somebody out there please assist with regards to how i would wire the db 25. on the TDD micro i would love to know what wires go into the "torque,index,dir"pins .

    lastly
    please help with mmos 2014 settings when using a 60 cpr. it says u cannot use anything below 256 cpr
    its set to pwm(hbridge).

    Nice idea/job but the new fanatec DD is quite cheap too. I have 2 old g27 somewhere. If you manage to pull this up I might try it too. Good luck
