News DIY FFB wheel STM32 ver.(work in progress)

Here is a new Update to anyone who is reading this I have got some ceramic capacitors with 0.1 uf at 24v(10) of these little guys and put them in parallel with the motor till the noise is reduced to some extent if yall are trying to replicate this please stay within the range of 0.1-1 uf don't exceed as it will smoothen the PWM signal more aggressively and my impact response time. Happy experimenting

Guys am back I have ordered a new chain and a sprocket for my motor which has a 11T sprocket by default the one I ordered is 80T and chain to go with it.

So for anyone interested gear ratio is 7.2727:1.
And the torque will be 6.4 at 364 rpm
Tell me what you guys think about this.

New update guys i am upgrading to STM32F401CCU6

its way better than the leonardo and cheaper to in some parts or almost more or less the same price.

And I will also be upgrading to emc pro as its got more features than lite

I have also got this setup for the gears 11T to 80T I have mentioned the ratio somewhere before along with others details.looking forward in putting this together.

Update:


I have just put this together quickly (material plywood).

Update:

this is the testing set up for now works a like charm.
this is the link to the video.enjoy

Hi

Me too, I’m working on an FFB wheel project, and I think using an STM32 is better than an Arduino Leonardo. But I can’t find a wiring diagram. Do you have one?

Hello, I have a STM32F401CCU6 and I made a first version of simulator without ffb and now I wish I could add it. I read a lots of forums and post and I don't know what to choose between a MY1020, a MY1016, a MY1025 and a MY6812. I already have a 12V 15A power supply and if I could spare mony by using it, it would be nice.I saw that we may undervoltate the motor not to hoverheat it. I thaught I would buy 2 or 3 bts 7960 H bridge tu run it.
Could anyone help me in a choice please, thanks !

Here is the wiring diagram I used for EMC pro

Check my previous posts there is one provided Thank you for your support

Try My1016
but i would not recommend the Bts cuz i had many issues, as i could to find the original and most are clones and you can't tell em apart so I have tried with 2 bts in read the previous post they died rip procced at your own risk!!

Update:
I am currently working on 3d printed Plantery gears This may be hard for some people to acquire, but there is always the belt and gears Or the chain and sprocket way to go!(Check my Previous Posts on this).
Anyways back to the main topic 3d Printed Plantery Gears the main reason is that i have a 3d printer and
i want my wheel to look professional And Conpact at the same time.(Btw its still a work in progress)

So the Raito here is 8:1
Edit:
Any Mechinal engineers out there Plz Your help would be kindly appreciated :_)

Hi Guys For those of new here plz do check the previous post to stay Up to date with my project.

Okay thank you for your answer !

What is the use of the NRF24L01 wireless button receiver ??

I also planned to use it and I don't find any information of how to do, I can use a NRF24L01 wireless button receiver and then... How many button can we connect ? there are 32 button on EMC but how could we wire them ? If someone knows I would be happy to know ! thanks

I have this diagram, and some info. I am using a stm32F401CCU6 but the dev told me I would need another F103C8. To be honest I am not sure to understand the diagram. How many button can we use with one stm32F103 and one NRF24L01 wireless button reciever
Thanks for your help

idk much about this but i think its is a small button matrix for the to be attached on the steering wheel it self instead of using that coil cable for a much more cleaner look
eg: this would be with the coil cable

and this without:

According to this diagram, i think MAX buttons are 23
and for the wiring refer to the main diagram it self
and if possibe connect the dev cuz i dont kown much about this wierless this my self
sorry for not being of much help

Ok no problem thanks for your help !
