DIY Pedals & Buttons Controller

Is it normal for the v.16 to pull up "2 controllers" ?

hmm, no maybe its joystick test's "feature"
windows shows one joystick for me

Really love this project. I'm planning to recreate this wheel with it.

I'd like to connect the rotary switches using the analog 2 button function. Normally the rotary switches have 12 positions. I plan to connect a resistor between every switch position to convert it to a 'potentiometer'.
Can you increase the max number of buttons per analog axis to 12? And maybe increase the resolution to 9 or 10 bit as to have a greater range available for a button.

Hi @Rooligan
Not sure, why you need to convert your rotary switches to pits, if the Fw has support for rotary switches already?

@dimitri
Howe to connect 2 potmeters for clutch on same axle
can you show drawing of it.
I have 4 rotarie encoders 1/4 step after fiddling with wires all working perfectly same for the buttons.
i had problem with pro micro not getting the rotaries to work,but stm32 is top

Must be @TOPMO3

@TOPMO3 very nice work, i have the same problem like @Nick Moxley i see 2 OSH Controllers and in default config i have first 6 buttons on:

I know the fw supports this. But that would take a lot more wires to connect to the board.
If you put a resistor between every step of the rotary switch, you can use it for an analog input with just 2 wires.

For the wheel I mentioned I would need a grid of 6x6 rows and columns.
It would be a lot easier to wire with just 2 wires for each rotary switch.

you should check "combined axis" than 2 inputs will work for the same axis. for example below one half of axis will came from A0 and another from A1

it seems something wrong with new combined USB descriptor. some people also report intermittent "USB descriptor will not be recognized" errors

well, yes you can connect rotary switches this way. Changing number of available buttons for one input is not easy as changing one digit in code however, it'll take some time to increase it

@TOPMO3
the question is about how to connect the 3 pins of potmeter to the stm32
From A0 to A6 potmeter pins so looking above on potmeter left pin of pot to A0 and so to contineu with the other 6
Ore i use only the the left en right pin of potmeter en not use the middle one?

Hi, I followed the tutorial in full, but I have a problem. The OHSstudio software does not detect my STM32 board. Does anyone know why this may be due?

Thank you

Did you look at this site its from topmo3

Maybe solution here

Thanks for your answer.

I also did what is indicated in that post. I installed the firmware and the program did not report any errors, but OHSstudio still does not detect the STM32.

On the other hand, if I connect the STM32 via Micro-USB, the PC does not identify me as any device. That is, it does not appear in the device manager.

To rule out that it was a board problem, I followed a basic programming tutorial using the arduino IDE that turns on the LED that has the board and works, but neither does the PC detect it on any COM port.

Hi, I bought an STM32 board to make a steering wheel and I am experiencing a series of problems that cannot be resolved due to my inability.

It turns out that I installed the firmware on the board as the OSH Studio website says, when adding a button it is kept pressed, the funny thing is that I have not yet welded any cables to the board, if I made previous attempts but currently not It has none.

Then I will leave some screenshots to show what I have at this time.

This is how it looks in the OSH Studio



This is how the STM32 board is



And here is a sample of what the pressed button looks like without having a single cable soldered on the board.



Please help

It doesn't appear that you have soldered the Header Pins properly on the board, Please take a better picture of the Soldering job.

Imo your likely not using Flux, So do yourself a favor and pick some up please, Soldering will become a LOT easier with good quality solder and Flux.

I think I'm useless doing this haha

Problem solved, thank you very much for the help!

i have a problem my board is not recognized .i followed the tutorial but i have a problem.....possible solution yks

get config from device and save config to device is not possible to click

my problem i think ..its' not recognized a firmware .(look the black arrow) ...and the others black arrow is not possible to click
