Arduino for STM32

Right, you should post your sketch.
Then I will try.

@kvv213

ADC3 should be functional, anyway as a workaround use the other.
I will have soon an STM32F103 based board with ADC3 then I will be able to test.

One other approach could be to add the USB composite as a standalone feature mutually exclusive with the default USB stack from ST.
I'm following the TinyUSB project which seems promising.

Let me know what is your entry point for USB.
Probably we coiuld add the HIDComposite as a library.

Hi Tazzi This forum is more dedicated to stuff around STM32 usage in Arduino. I guess you should better ask on ST community. I'm not a CAN expert so could not really on this anyway is someone has some clue. You could also check the latest official example here: https://github.com/STMicroelectronics/...

The config for the Serial speed is made automatically using the method.

Fine to know that STM32 core is compatible with SDFat fro Greiman.
Anyway, this topic is linked to use it with @stevestrong core for F4, if I'm not wrong?

digitalToggleFast is lower because it read the register before invert it's value.

Hi @Jblb

I thought to add it as it is really useful like on GitHub.
So, it's done.

Could you share you example sketch?
