Open FFBoard DIY FFB update 4: ODrive, VESC, HID Communication

[@BramHarmsen]

Nice progress again! Very cool that you were able to set the wheel rotation from cm, that's one of my favorite functions. Ideally all sims would have this functionality.

Hi, amazing project man, congratulations!!! Real open source!

[@josebatista8981]

Would you be so kind as to create a code to control the vesc through uart for the stm32f411, because this one does not have a can port. thanks my friend for this project is already amazing

[@temyraverdana6421]

Wow, an incredible work. Thanks for share all your effort to teaching us

[@ChristianBrunschen]

Great progress, many thanks for the update!

Do u have a video of the odrive configuration or planned?.

[@johnlawrencebernardo8059]

Hope you could do a hoverboard motor version of the build

Hi, I ordered a couple ffboards last week to experiment with, and I want to build a force feedback joystick. I’m struggling on which motors, encoders, and controllers to get. Can you please suggest some options.

[@leonardoaugusto5491]

Amazing job. I bought a 8nm servo from kollmorgen, but it came with a resolver, and it's hard to find a small and precise encoder to fit in it, so I'm using a amt-103 to make some tests. So my point is, is it too complex to develop a resolver converter module ? Would it be possible for openffboard software to give support for that kind of sensor or is it too much to ask? Cause resolvers have a excellent precision, but I need to replace it with an encoder

[@Gigawipf]

Resolvers are difficult to drive and would require a lot of active analog circuitry to extract a usable Sine/Cosine signal from. Probably possible but i don't have enough time at the moment and also no resolver to test.

Приветствую тебя друг. вопрос такой, руль на твоей базе реально ли подключить к игре форза? если нет, не беда, я понимаю что сама майкрософт решила вырезать все сторонние рули. С другой стороны, ты очень крут:)

[@bennguyen1313]

Any thoughts on the powerstep01 vs the TMC4671? For example, I have a high resolution encoder for position, so I really just need a stepper-motor driver that can deliver the torque. I like the 10A that the PowerStep01 can do, and that it can be configured either for Current-Mode or Voltage mode. Other ST devices, like the L6474, can only do 3A rms (~4A amplitude).. although the datasheet says it can generate a pulsed (

[@Gigawipf]

The first attempt was based on the powerstep with some foc trickery. It was not stable, the resolution with 7 bit extremely low and it ran super hot. The tmc with low Rds mosfets and its 16b adc is much much more efficient and capable.

Hello, I would like to test this firmware on a STM32F407VET and VESC 4.12, how can I get it? It would be a pleasure to try and support the project.

[@nyftn]

i was able to get a fanuc am9/3000 motor . would it be possible that for a DD wheelbase

[@lio1234234]

Great stuff! Do these new hall sensors mean we no longer require an encoder for the motor? Or is that still needed?

[@Gigawipf]

It has nothing to do with the encoder. The motor still requires an encoder. I am referring to the on-board current sensors in this video.

[@Edgard422]

Hi, I bought a STM32H7 Dev board to use with another firmware (VNMWheel), but yours looks better, and it is open source which is great. Would I be able to use this board with your firmware and your custom driver?

[@Gigawipf]

Not directly. The firmware is made for the F407VG and would require porting to any other chip. I am sure it can be done being a mostly similar chip but the differences in architecture would require some changes.

[@Edgard422]

@@Gigawipf My friend bought by accident the STM32F4VE DevEBox, so I suppose this one will work fine?

[@Gigawipf]

@@Edgard422 F407VE? that should work but there currently still is no build specifically for those devboards and they sometimes require extra hardware or remapping. Like encoder pullups, usb vsense and buttons

[@Edgard422]

@@Gigawipf Oh...ok ok, I think I would be better ordering your custom board with the driver then. Thanks for the answers!

[@EdsonSouzaSimraceChanel]

Can you please send me the link where I can buy the plate made by you?

[@Gigawipf]

My tindie store is linked in the description but currently all out of stock because of part shortages. You can join a waitlist but i can't promise any date. I am waiting on parts myself.

[@ThebusWay76]

Good day thank you for the great videos. I need so help with wiring a hoverboard main board and STM32F407VET6, I am a complete noob when it comes to electronics and would really appreciate any help. I have managed to load FOC firmware on the hoverboard main board and VNM firmware on the Stm32f407vet6 for a diy ffb steering wheel. I have a 600ppr incremental encoder and I will be using the hoverboard battery to power everything. Thank you again for sharing your knowledge/experience with all of us.

what do i need to compile the sources?

[@Gigawipf]

STM32CubeIDE, import the project and compile the subprojects in the targets folder. If there are any errors check the path settings.

I will make them available once parts are available for a reasonable price again. At the moment some required parts are way overpriced or out of stock.
