    Maybe this is your problem too.

    Hi, sorry for my bad english but i have the next problem, and i need some ideas and some help. I have an arduino leo with the EMC firmware and i plug it (with the same wirings that are at they page) an hn3806-ab-600N encoder. The problem is that when i spin the encoder clockwise, the EMC soft turn the wheel clockwise (eg. 10 degrees), but when i spin the encoder the same distance bue anti clockwise, the EMC soft almost doesn't turn (eg. 2 degrees). So the steering wheel lost the center, lost the alignament. Anyone have some clue? the same wiring with the FFB soft works fine

    Been working on a DIY FFV Wheel with an Arduino and a Omron E6B2 1000ppr Encoder (Chinease Import). But I have been struggling to get a signal out of the endoder, I have verified the arduino and the software works using a cheap ~20 ppr encoder (the ones with the click button). I have tried with and without resistors (1k & 4.7K), with the Omron.

    Does anyone have any ideas on what I should try next?

    Hey I read you can use STM32 or Arduino Leonardo. Is there any advantage for the stm32? Its roughly double the price, but its not so much money anyway. Since I have neither, which should I get?

    Hi there! How are they? I tell you that I was able to finish the steering wheel, the truth works perfectly. but I have a problem in assetto corsa, that's why I write to you. In the test sessions, the feedback is not working properly for me, the steering only gets heavy when the car is not rolling, the track, piano and off-track effects do not work, and neither does the gain. I already tried with the configuration of the feedback of the game and it does not solve it. Can you think of what could be the downside? I assembled it with arduino leonardo.

    then I upload the photos with the latest version.

    Thank you.

    Ditch the Leonardo and get an f401 board, then use emc developments firmware. You will not be disappointed. Yes, it costs a few euro but WELL worth it over mmos etc and is in active development.

    Hi there! I have a problem with my encoder (from Canon IP2700). It worked for a while but it stopped working, I can see that the red LED inside is on, but the Arduino Leonardo is not receiving the signal from it. What can i do?

    Hello!
    Just finished rebuilding my Thrustmaster RGT using stm32 board running Mmos coupled with bts7960 powering new 24v/360w DC motor and it all works for most part. I am struggling to get ffb working properly. Overall it do works, I have end stops and some effects but they seem to be most noticeable when at max angle. When near 0° angle there is literally nothing except high spikes when crashed or so, sometimes they came stupidly strong out of nowhere like when testing on F1 2020 where on fast straight no ffb and when slightly turning wheel it literally fight me. From information I gathered here in previous posts, it may be a problem with how bts is wired or mmos setting. Using pwm/dir mode, the BTS is wired like this: pe9 (pwm) on both EN inputs, pe10 (dir1) on RPWM, pe11 (dir2) on LPWM. Idk how to propresly setup mmos config. I ill be gald for any idea how to make it wok proprely. Also what about EMC? Is that better/worse, any issues with BTS modules?

    Don't use pwm dir.
    Pwm h-bridge instead. And look carefully how all is connected in schematics.

    I did try it previously, but not tested in game since i did not liked that braking effect. Is there way to get around it or it is something I have to live it? Thanks
