DIY FFB Steering wheel (MMosFFB ) (In Progress)

Help me to check encoder with other Arduino code

Try this - I just whipped it up but I have not tested it.

Encoder A/B lines need to be on pins 2 and 3 (not 0/1 that you have/need for the AIWave firmware). Rename to ino file and load using arduino program. Open the serial console at 115200 and you should see a number printed as you move encoder. One way it should go up, the other it should go down.

In serial monitor screen no numbers are shown

you changed encoder to pins 2 and 3? I'll have to spin up the code and test it properly but it should work

I tested the code and it works fine for me

Is this code is suitable for this encoder

I cannot get output

I have no idea, but if my code does not work for your encoder, it will not work for aiwave firmware. Perhaps you're best off contacting the person you said had it working with that motor.

Without technical information on that encoder, it's impossible to help

Edit - you still have not confirmed swapping to pins 2 and 3 for encoder. Importance in detail

I think encoder is not working
I decide to buy a new rotatory encoder from orange brand
How much ppr value you prefer for this project

1000 PPR is recommended but it can be whatever you want really. More than 1000 is limited/no benefit and more overhead on mcu. Too low and you lose resolution but still works. Something with a z output helps too.

BTW, I don't really recommend aiwave firmware overall, it's old and outdated these days.

In my wheel config software the marked options are not shown

After I bought new Leonardo R3 board and encoder but now also I gave the same problem

Is the software properly work with windows 7 I use win 7 operating system in my pc

It's under advanced - you set PPR and drive type

But as I have mentioned here so many times, why run 7 year old unsupported software? Aiwave was abandoned. You could have swapped to EMC firmware on stm32 for less than the cost of your new Leonardo board...

I am very happy to share this
I connect same thing with with wheel check software with another win 10 pc
It works properly

That is good to know but odd - Windows 7 would still have been quite popular when AIWave was made.

Hello,

I'm currently running EMCpro on an STM407 with a BTS motor driver driving a 180W 24V DC motor on 200W 24V power supply.
The issue I'm having is after 1-520 minuets of racing I get a sudden & quick loss of all FFB. When it re engages half a second later it looses center, thinking the current wheel position is center.

I believe its the motor driver protecting itself under high load and/or heat (its fan cooled and not getting hot so not sure on this).

I see some people talking about using 2x BTS drivers, is this a possible fix, or for people using two motors?
Secondly, is getting a FSESC6.7 motor driver as recommended by latest EMCpro docs going to fix this?

That sounds like the board itself resetting. If the BTS went into protection, the board would still track wheel position.

Hmm interesting! that makes sense actually.

Its a STM board from Aliexpress so that could be it. It had plenty of sales and good reviews but possibly they weren't using it for high stress applications.

Would you recommend getting a STM from Amazon to test?

Cheers for the reply also

It all really depends.

What board do you actually have and how did you connect the BTS driver?

i.e some boards only have a low end, low current 3.3v regulator on them whereas the better ones have one capable of a lot more ma.

Make sure you drive the BTS from 3.3v, not 5v or you will have issues. I actually added an extra 3.3v regulator just for the BTS. I also run 3 in parallel as well.

Got a link to the board you're using?

Got this STM

BTS connected to 3.3v, 2PWM already haha

What does the wiring look like with have 3 in parallel?

That board should be fine - It has the AMS1117 which is good for about 800ma from memory. Try different USB ports/cables.

In parallel mode, you just daisy chain the modules pin for pin.

I also recommend using PWM+2dir with EMC and the BTS7960 modules.

From the module - Short both 'EN' pins and connect to the PWM output on the controller, then use the 2 dir pins to PWMR and PWML. I know it sounds daft but it works and means you don't get drag on the wheel.

Yoo, my man, PWM/DIR is so much nicer your right about the drag feeling!

Still cutting out though :/, thought it was fixed too

Might try out 2 BTS drives. Cheers for the wiring, guessing you wire the power and motor to all drivers
