    Hi everyone,
    I made my first SIM following the Racingmat tutorial


    with two variants, power of the 12V 235W 26A motors and rotary sensors with HAL effect (I destroyed an exaggerated amount of pot).
    The constant that repeats itself is to burn MMS (the last one is original Sparkfun price 72 €). Everything works fine the firmware contains two test functions. TestPot and TestPulse, both make RIg work correctly (Sim Tool not active).
    When I switch to manual movement in SimTool (last vs. available) it moves badly, jerky, or does not move afflicted. I set the default preset as SimTool expects. After several attempts I think I also burned the last MMS because it no longer runs TestPulse, the RIG is dead.

    I'm considering modifying it like this from RufusDufus:


    I asked for advice and help in that post, it is quite disheartening not to arrive at a basic result considering that other users of this forum have created the SIM proposed by RacingMat with satisfactory results, my request is addressed to these users that year made my own experience to understand where I'm wrong and finally get some results.

    Thank you all
