DIY Pedals & Buttons Controller

No, I mean yellow jumpers



you have 2 options:
- you can make "connect after reset" - in this case you don't need to switch jumpers, just hold reset button and then choose connect from menu
- you can switch yellow jumpers and then stlink utility can connect to the board with no problem. In this case you don't need to do "connect after reset"

Ah thank God it works.. Thank you very much buddy. Then i'll downgrade into 0.13 and try. I'll report here after finished..

Hello TOPMO3.....today i receive ST-LINK V2......i did all erase....flash with 0.13 and device found from windows....but when i open OSHStudio after 2 seconds program crashes....
i did a reset with changing the jumpers....flash with 0.14....device found from windows.... open OSHstudio.....crash again!!!

what is the problem?

I have change USB ports....

I got a lot of similar problem reports last time. Don't know what is changed, I can't reproduce the problem on my side, so its a little bit harder to resolve. Currently investigating the issue though

@f1simgames you might be able to help @TOPMO3 if you check Windows event viewer to see if it gives any clue as to what is causing the crash? I'm currently having problems with my PC thanks to the latest Windows update messing with my Asus drivers.

@TOPMO3 , today i test it to another PC runs windows 10.OSH Studio work normaly...So maybe is something on windows 7 ?

Finally got to making my rudimentary button box using your tutorial @TOPMO3. Easy to follow and setup, thank you.

She ain't pretty but she works

Am now planning a proper set up, just got to wait for everything to arrive.

A bit of a derail here sorry - Mods delete if inappropriate.

@TOPMO3, do you know if this will work on a Raspberry Pi after being setup in Windows?
Would be a cheap way to make a fight stick for emulated fighting games.

Hi @Quail85, no the FW won't work on PI

Thanks @TOPMO3

On a proper note, v2 of my truck sim button box is complete!

Thanks for your guide and awesome software!

hello all....do you have use these rotaries ? https://www.tme.eu/gb/details/ps1010-20/rotary-switches/ctr/ps1010-20-kq15a60-000/

I have ST-LINK V2 and STM32F103C8T6 (BluePill) with latest firmware (Version 0.14).
The controller is work:


But when I open the OSHStudio and "Get Config from device", the OSHStudio is freeze.

Windows 10 64bit Pro.

Testosteron default

Restore default config->save config to device->load your config-> and now this option propably work.

"Get Config from device" still dont work. OSH freeze.
Two yellow jumper is 2-3?

I also had this hang up issue, seems to like to hang when you press the "get config from device" there's a sequence of plugging the board in and getting one shot at that "get config from device"

if it would hang up, you have to restart the process.

Fire up the OSH software, Plug in the board. then ask for the config, Sometimes it worked. Sometimes is froze up.

Win10 74 here also


PS windows has been messing about with drivers this last update and they gone done Broke Shit....., there's a thread on AC forum about it.

Hi @TOPMO3
I would like to ask you a question because I am curious to know if my idea is feasible. In your opinion, is it possible to use the STM32 to emulate the thrustmaster's F1 rim?
This solution would allow many people to use a DIY rim on thrustmaster base for console too.

Hi thanks for the tool but I can't seem to change identifier, it always stays the same.

Great project! Very soon I will start a development with him

I have the same problem reading the configuration, it works in windows and OSH find the cards fw etc but hangs if I press get cfg from device



Have tried reset to default and connect the board before and after the OSH has been started, also connected directly and not thru a usb hub.

Any ideas?
(w10 64bit)

try to reset all pins from menu before read config from card...
