DIY Pedals & Buttons Controller

Thanks!

Thats the one

I'm trying to program the STM32 for the pedalbox. I tried version 0.15 and 0.16.
The ST-link software says it's flashed the chip.



After connection to regular USB, Windows doesn't detect the device, nor OSHStudio.

I've tried an Aliexpress one and an original Bluepill and both have the same problem.

Anyone have an idea?

I've tested Freejoy aswel as OSH but both boards are not recognized. Help

Hi There,

I've flashed the firmware with ST-link and can see the correct FW in OSH Studio.
But I can't write my config to the board in OSH studio. The program doen't respond to send or get config from device. Can someone help me with this. I've just completed the complete wiring of my DIY wheel and like to try it out.

i finally had some time last night to mess around with mine.
i have the round type reset button.
my one recognises all my buttons, all 24 of them.
i did notice after programming that both leds on the stm32 must be lit when connected to the usb cable for the osh software to recognise the device.
thats as far as i got so far.
need to connect 5 encoders but could only get keyes encoders with the built in circuit board.
not sure if it will work or if the button pins are independent of the encoder pins. 5 pins in total that are marked gnd, +, sw, dt, clk.

looks like the keyes encoders wont work properly.
i got the buttons to work.
Then played around with wiring and got the encoders to work but on the osh studio when i turn the encoders a different combination of 5 multiple buttons are lighting up.
tried it in the settings screen of Content Manager for Assetto Corsa but all encoders are registering as button 49 and button 50.
pressing them is working fine.
will try again tomorrow.

Finally after a lot of patience and trial and error, i got it working great.
Turns out the encoders cannot be all set to one type of step and i had to use 3.3v on the ground pins and ground on the 3.3v pins
Had to keep changing and juggling each encoders step value till i had no conflicts.
I used the single encoder layout.
When trying the chained layout i could only get 2 encoders working and as soon as i added number 3 or more, it wouldnt work.
have 22 buttons + 5 buttons on the encoders + 5 encoders working great now.

Still have to add on my sequential gear shifter and a handbrake.
Will see how reliable it works and then decide if i will add on my VPP pedals.

i initially had a similar issue.
what i noticed after flashing the firmware you must swap the bridge plugs and make sure both leds are on for it to be seen by software.

Hi, its posible add load cell ??

Hello, greetings from Argentina. Works with load cell and amplifier HX711??

please help me circuit diagram

Can any of the pins be used as an output ??

As in PWM to drive a DRGB strip, Fans for wind sim or output to a vibrator to simulate ABS engagement

Hello, I have two problems with OSH, first the device does not recognize me normally, I have to remove and put the usb until it recognizes it, if I use freejoy I do not have that problem. Second, I have a blocked stm32 but only with osh, I can neither read nor write from the software, but if I install freejoy I can record without problems.

Good afternoon, I have a g27, I take good care of it and it is old, but it still works well,
I've been thinking about putting a controller in it to put the pedals separate, which one do you think is better this board or the arduino micro, do they have the same steps? I think not the arduino micro, if I remember correctly they are 1024, I don't know if I'm wrong, I have steering wheels with an arduino micro, which you recommend.

I just find out about this great software.
I had already this board lying around so I started to play with it.
Until now everything I attached to is working fine, also potentiometer.

Only thing that does not work is comnining 2 potentiometers.
No ,atter what i try they both work as one but not cooperative

Pot 1 is attached to A3 and 2de to A5. Bar AXIS 1 and AXIS 2 move as intended when i turn one of those pot's.

But according to Combined part, as soon as i choose Cooperativework, AXIS 6 should move, But nothing happens there

No idea if this could be the case because my board has a square reset button?

Also wonder if anybody attached a Hall sensor to the board and configurated with OSHstudio?

Mymistake. Cooperative work on both pot's is working fine. Had to change the Calibration Value on Axis 6. After I changed to 0 and 4095, I finally see movement

Only issue I still have is the fact that on windows I dont see any pot movement. Device is recognized by Windows , and buttons light up, but no axis movement visible. Only on OSH Studio

I encountered the same problem, then I tried a different usb cable and now my STM32 is detected

WOnder if anybody had a clu what this issue can be.

I am almost done with my DIY Sim steering Wheel. Have a total of 14 buttons , 2 rotary and 3 potentiometers running on 0.16 version of OSH Studio.

Evrything works as it should only having 2 strang issues.

First one

Potentiometers are used as Clutch , and sometimes without touching my clutch handles, bar of potentiometer goes all the way to the right on the OSH software meaning my car has no drive.

This can be solved by operating the clutch pedal .

Second issue:

SMT32 board stops for a few second , meaning that none of buttons react. No great when you need to change gears. After a 2 or 3 seconds everything works fine again.

Windows does not give any USB disconnect /connect sound, so i have no ide what the issue could be.

Wonder if going back to V 0.15 couald solve both problems.
or maybe something else I need to change to stop this strange reactions.
