DIY FFB Steering wheel (MMosFFB ) (In Progress)

All of them should work fine but MMOS is pretty outdated these days. EMC Pro on an STM32F407 or OpenFFBoard would be the way to go.

Both are still in development, but both have somewhat left behind traditional H Bridge control (OpenFFBoard more so, only older versions still support it). EMC is a bit more DIY whereas OpenFFBoard promotes using their specific manufactured boards (but you can use a generic dev board).

hey man, I am building a DIY FFB wheel and everything works great except pedals.

when I keep motor off they work great but when I turn on motor, the pedals start flickering crazy, like almost half range flickering.

do you know why this is happening and how can i solve it?

How have you connect the pedals to the Arduino? Are you using Dupont style connections wires? I had a similar problem and it was resolved when I soldered the wires direct to the Arduino. I hope this helps, it did work for me.

yeah its dupont flat rainbow cables.
so can i just twist all 5v cables together and solder them to arduino?

Hi how many 5V cables do you have(that can work) all the other wires need to be soldered also, because the Dupont style connections don't all work well especially the cheaper ones. The best practice is to solder to the pads on the back of the Arduino board an make sure to use some type of insulation to prevent shorting out the wires. Have a look @ what I did in the share picture.

pedals, handbrake and motor driver. total 3 5v cables.
yes, soldering on back on arduino seems like a solid choice. I will try that.
BTW what type of shielded cable are you using, did you buy it or remove it from somewhere?

I just cut a length of RJ45 network cable, and I use the RJ45 socket to connect the Arduino to my diy pedals.The 8 wires inside are more than enough for my pedals.

so if I just solder dupont cable will it work or would I need other cable like you are using

Soldering will be the best practice, but be sure to solder @ both ends of the Dupont style connections, to ensure positive connections. I hope this works out for you, I know how frustrating that glitching pedals can be. Best of luck and please let me know if it works, thanks.

yeah will let you know, thanks

hey, so I soldered everything and sadly it didn't improve the flickering. will need to try something else
