Arduino for STM32

Hi Arpruss,

Thanks for the pointer.

As the project was for an event mid November, I've found a quick & dirt solution: I have map myself an AZERTY keyboard over the QWERTY template I've found. Just modify the output code with a translate table.
The major issue was the need of the key "Alt Gr" to ...

Hi,

USBComposite is working like a charm to simulate a keyboard.

But, how to deal with key-mapping ?
On my test machine I have a french keyboard (AZERTY) and a "Keyboard.press('a');" give a "q".

Is there a way to deal with this problem ?

Cheers,

Phil

All the tests I've done are successful.
I've played with several bootloaders and I can program it with the Arduino SDK.
Sometime I need to do some "connect under reset" to flash it, but I don't remember the exact case.

I've also played with the timing, to keep it in DFU mode, or keep it longer in ...

flashing and retrieval probably works, check the options for dfu-util.
it probably works the same for stm32 native usb dfu as well, e.g. the stm32f4xx series.


Yes, that was the right path. Got the flash zone after bootloader by DFU, with dfu-util.
Thanks for the suggestion 8-).

Now I need to ...

Hum, I have some doubt ...

I've flashed the bootloder on a bluepill and here is what dfu-util told me:

Hello,

I start a spare-time project with some bluepills.
It needs to be managed only by USB. That's the only port exposed from the bluepill.

I was reading the Roger Clark's bootloader source code regarding the DFU features :

Hello everyone,

I've just start a project with a bluepill, mainly collecting data and get them back.

I've start to play with DFU but with no success, so I guess I'll need some helps ...

Best regards,

Phil
