DIY FFB Steering wheel (MMosFFB ) (In Progress)

brazilian?

I do not know if this engine is Brazilian! I do not think so!
I'm having trouble finding the encoder 8000ppr, does anyone have a link so I can buy it?

hi @auryza

i have decided to make a similar wheel you yours using a 300w unite motor - but i will try direct drive

is there a thread for your build ? can i see the arduino code ?

did you use the leonardo because it can be seen as a windows keyboard / gaming device ?

Leonardo is used for operating as a joystick / keyboard device.

I believe this project was finalized, but the creator made available a code from an initial version. I use the final version (FFBWheel.0.16.leonardo.hex), but I am studying and modifying the initial code made available.

Look for RFR Wheel Ai-Wave, you will find the thread.

Hello,
Plenty of them in Aliexpress.
Check this, Omron encoder,
PR means pulse per revolution, multiple by 4, you will get CPR. If you will order encoder with 2000 PPR overall count per revolution will be 8000.

Hello,
I don't have a thread of my bild, i was using info from Racingfr forum, but at this moment it's closed.

Leonardo is used for operating as a joystick / keyboard device it's cheap and easy programmable.

And this is really easy to build, actually all information what you need to know is on this thread.

Some videos :

wow awesome videos ! is the software he is using the mmos ?

Actually the same.

So does a pc program control the ffb or does the arduino do it ?

Can you use as many ppr as you want ?

Everything the same like in OSW. Arduino controlling the FFB, software is for profiling.
I don't know how many PPR can handle Arduino, i never have tried more then 2500 PPR, but probably it can handle as much as 10000 PPR.

I found that arduino internal timer can handle 65,536 interrupts, and the it starting count back to zero. So that means if you will use max 1080 degrees wheel rotation, u can use 5000 PPR encoder (20000 CPR). I don't know if i'm right. If somebody know better please share.

I have a 360 ppr shaft encoder to hand i will start with that and see how it works.

Does the osw project not use a stm32 processor ?

Yes, stm32, and this software modified for Arduino Leonardo.

is there no source code for the arduino ?

I want to compile for an arduino mega 2560

the original code was for a STm32 board - how did you get the arduino hex file ?

Are two different projects.

The (initial) sources and some docs are here: http://www.aiwave.fr/downloads/ESP_WHEEL_0.3.zip (this is not the latest version but it will help you if you ever want to jump into FFB development).

This is the source code I'm studying / modifying, but in some games the FFB does not work, I do not know, but I think it's something related to the USB FFB descriptor.

You need to download and open XLoader , the from drop down menu, just choose mega 2560,

All files you can find here

Xloader.zip

thank you guys

i tried programming the code for the mega - but it did not seem to work. Does the arduino need to be a leonardo so it can emulate a joystick.

i will keep trying

So it's a bit tricky to program arduino with "xloader", first of all you need to restart arduino into bootloader mode, then arduino generating other com port number, whish you need find and write in to xloader com port , then you have 10 seconds to press flash button to install a hex file, that how this works with leonardo and macro.
And with mega board probably that method doesn't work.

do you have a compiled version of the rfr program ?

how does the mmos program find the wheel - is it looking for a windows device or a com port ?

should i be trying to load the hex file FFBWheel.0.16.leonardo.hex ?
