Thanos Direct Drive with AASD 30 driver

@Thanos - I have been having some trouble getting the pedals on my sim to work correctly

it appears the 5v for the g27 pedal connector is actually 3.3 V not 5V

there is a wire soldered to the board that says 5v (pic to follow)

is there somewhere else on the board I can take 5v from ?

please advise

@Thanos

The pedals and shifter do need to work on 3.3v, as the logic and analog signals from STM32F4 need to be 3.3v.

The jumper wire you see on the photo is to also provide 3.3v power to the DAC as it doesn't needed 5v as I thought, but 3.3v rail to rail to have less gap on the offset center for the torque signal.

Managed to fit a smaller resitance potentiometer and the pedal is now working ok

The sim wheel and pedals are finally finished, its been a mission - in hindsight it would have been easier to buy a working wheel and upgrade it to a more powerful motor.

I will fit a vibration motor to the brake pedal so it vibrates with the abs

Anyways we have a new problem

Sim tools is crashing, but only when the TDD wheel is operating.

If you power the sim with the wheel motor disabled there is problem.

My guess is I am getting electrical interference which is jamming the usb hub causing the 6dof com ports to drop out and making simtools hang

Sometimes it will work for a while before crashing.

I am going to try a usb isolator between the sim wheel and and the computer

Any suggestions ?

Has anyone else had similar issues ?

the cables are shielded and I tried the magnetic chokes earlier today

i will try rerouting the cables to the AASD and see if i can move it to the other side of the sim

Ok moving the aaad away from the sim computer seemed to help

However now RF2 crashes instead of simtools

I am not having much luck with the TDD board from thanos

it appears the FFB is reversed when using Rfactor and other programs

is it possible the direction pin is sending in the wrong direction ?

is there a way to fix this ?

the MMOS settings from Thanos recommend the encoder is reversed - but doing this makes the wheel spin when at the desktop

i have tried changing everysetting iu can think of - e.g

in RF2 the json file for the controller is set to

"Steering effects strength":-10000

I have tried very hard with this TDD wheel and I am starting to think the direction pin is wrong

There's a inverted dir pin in mmos, try using that one if possible.

Alternative would be to reverse encoder as you did, or put A encoder wire into B input on mmos and B into A.
I think that you'll absolutely need to change dir pin because you can reverse the encoder but that will just fk up game input and you'll still have reversed ffb.

Try using a little bit of desktop spring and see if your motor moves away from center - if it does dir pin is reversed (idk if you did that already, something like this was mentioned in your post).

Thank you - that is very useful

Finally a breakthrough - reversing FFB using MMOS and RF2

Ok finally a breakthrough ! Windows 7 makes local user copies of ini files and when you edit them it may not be the file that windows ends up using !

The solution for RF2 is edit the json controller file so the steering effects strength is -10000

Now save the json file with a new name ie MMOSv2

Now open rf2 and load the new controller file. Windows 7 has to use this file because there is no other one available

Problem finally solved.

I have posted the solution here so if anyone else gets caught out they will find the solution

The support for this product is not the best !

The TDD is just a better way to wire the STM32F4 minimizing the wiring required to use the MMOS firmware (plus adding a DAC to interface better to the AASD servos). So its being made as plug an play it can be to the specific servos it was designed for.

Theoretically if you follow the simple instructions and set the parameters on the AASD servo and follow the power on calibration instruction, the DD is ready to use with little adjustments in the MMOS tool.


Thanks
