DIY FFB Steering wheel (MMosFFB ) (In Progress)

First of all flash the Leonardo or Micro boards with HEX file, secondary install into PC "Wheel config" program, (similar to MMos), configure your wheel as you want. If necessary use "WheelChek" software to chek FFB . And that's it. , Leonardo recognizable as USB device. So no com port here.

i have got the board and have programmed the leonardo using the xloader program

when i open the wheelconfig program the com port for the leonardo can not be displayed - so i can not program the number of pulses

has anyone else had this problem

Are you using encoder a 2-channel or 3-channel (Z-index)?
If you are using only 2, make a jumper pin6 for pin gnd.
1- Connect to USB
2- Open WheelConfig
3 - Remove the jumper from the pin6 (leave a finger next to pin 6 to give the noise Vcc or make a jumper pin6 to Vcc 5v).
4- Move the handwheel / encoder and the program should acknowledge.
5- Put the pin6 jumper for Gnd

Now just setup and have fun!

You need to do this every time.
You can use a button, Gnd and a resistor for Vcc (pull up)

To test if your card is working, you do not need an encoder, using the step-by-step above and bringing your fingers closer to pin0 and pin1 (making noise).


If you are using a 3-channel, you may need a pull-up resistor in Z-index, but need to see the datasheet.

Reboot your computer and plug the usb cable leonardo the com port will appear

Hello auryza, I now encounter the problem is connected to the power, the motor will have been turning, do not know why, you can help me? Thank you!

Hello,
Can be three places where is problem, you need to invert pwm signal or wheel direction, and possible you need to swap power leads of the motor.
You need to find correct combination.

Thank you auryza, now the motor will not have been rotating, but the steering wheel to the right to a strong feedback, turn left no, is where I set up a problem?

Your encoder 2000 ppr = cpr 8000 . I think here is problem , if you have encoder 2000 you should and write 2000 not 8000. PPR means pulse per rotation, CPR count per rotation. Pulse has 4 times count.

And one more tip how to connect encoder to arduino board, you need to use pull up resistor. From positive to each channel. Look at the picture.

Hello auryza, My encoder is the Omron E6B2-CWZ6C-2000P / R rotary encoder ABZ three received Arduino Leonardo A, B, plus the resistance, into 2000 or turn the direction of the wheel without feedback ..

Which motor drive you are using ? Monster Motor Controller or Motor Driver BTS7960 ,
And check A and B channels of the encoder maybe you need swap the contacts.

thank you for the advice - yes i am using a 2 channel encoder

but the problem is not the encoder and pin 6

the wheelconfig program can see i have a Leonardo

but it can not see the com port number the leonardo is on - the option is 'None'

any suggestions what is wrong - do i need a different version of software / firmware ?

Hello auryza, my motor is 12v, ordinary 775 motor 150W, motor drive module BTS7960. Interchangeable encoder A, B items wiring, steering wheel to the left to play a strong feedback, right no ... Thank you very much for your answer!

i seem to have got it working

i changed the com port number to 1 in device manager and now it appears - was driving me nuts !

Gadget999:

Is there a com port on your computer?
If not, that is, Leonardo driver is not installed, re-install windows driver

If the drive is installed, sometimes Leonardo's port is not here, then you need to re-connect usb cable and restart the computer

thank you for the help

Every time when you using wheel config tool, you should short pin 6 to ground. Then software should recognize leonardo.

I afraid that is possible motor driver is half dead. One of the chip's not working, i had the same, you need proper cooling for this motor driver. They burn out really fast...
But first of all you need to be sure. Just try to invert in software and check if FFB changing direction, if only to one side is hard to turn, then motor driver need to be replaced.

Thank you everyone for the help - very much appreciated

ok looks like i am having the next problem

i have been unable to get the shaft encoder to send a pulse to the board

i have tried 3 different encoders

first encoder is 2 phase 360 pulses
second encoder is the same 2 phase 360 pulses

third encoder has a,b and Z made by omron - 360 pulses

---------------------------------------------------------------------------------

i wrote a small program to check the pulses - it appears the only pulse i can read is the z phase (1 pulse per revolution)

the omron sensor has come from a working device and was working fine

--------------------------------------------------------------------------------


do i need a pull up resistor on channels 0,1 and 6 ?

is there a way to configure the inputs for counting on different pins ?

-------------------------------------------------------------------------------


where can i download a later version of the wheelconfig program ?
