@s_d_a_i I am very grateful to you, the photos from the oscilloscope helped me a lot
P.S. I hope someday I'll get myself an oscilloscope

You have to download https://www.st.com/en/development-tools/stsw-link004.html#get-software if you want to program the pill with the st-link (I recommend you this way), this software installs the driver required for the st-link in order to work properly and even allows you to debug your code.

The first time you open it with the st-link on your usb port, go to "ST-LINK->Firmware update" so you have the latest firmware version on your ST-link, then "File->Open File" and load the .bin file, once loaded go to "Target->Connect" and then to "Target->Program & Verify", and now if you see no error it should be working.
(Flashing times are way worse on the clones).


Thanks s_d_a_i and megavolt.
only littles steps left...

This was useless, now I have a 2' cable (now I almost use the DC as the controller) with the same noise using this SMPS :lol:


@megavolt85, can you make a firmware version with a slower response? I think increasing the time between bits a little bit in the response may help with noisy environments.

Thank you.

This is the best gamepad adapter for dreamcast. I hope that megavolt85 will soon fix all the errors and I can publish the PCB shield for blue pill.

Hi megavolt85, I don't know what happens but I keep receiving the wrong data on the 4th byte in the command 08 so I'm having a lot of joystick down presses, this DC has the original electrolytic cap but I don't think this is a problem as the original controller works as expected even if the noise from the SMPS was affecting the communication on the stm32 why it doesn't affect the original controller, (maybe wrap it all with aluminium foil)

BTW, can you make a version with a lower bitrate (increase the time between edges on the TX part) so I can test it as well?

Thank you.

Feature requests (sorry!):
-For MAPLE Arcade Stick adapter: could you add Dreamcast D button?
-For Atomiswave games: could you use D as Coin input?

Understandable if its not possible. Thanks for your hard work!
