Hi @SunboX, unfortunately not. IIRW, On the forum some ones talk about this but I guess there is no progress.

> @SunboX Hi, sorry to ping you twice, but i just tested [my library](https://github.com/Levi--G/USBLibrarySTM32) with the default arduino MIDIUSB and it works, I included a sample in the repository, it...

Hi @4ndreas THis was discussed some years ago: https://github.com/stm32duino/Arduino_Core_STM32/issues/482#issuecomment-476229801 Main risk is the compatibility issue. I've added the request to the list.

Thanks @matthijskooijman for sharing. Just FYI it exists an uart debug feature which does not rely on IT: `serial_debug` Defining DEBUG_UART (USART peripheral, ex: USART1) and `DEBUG_PINNAME_TX` (PY_n) allows to...

Hi @ht93 , it seems not available fo F4.

> Hi @fpistm, is there any other way to implement this? I am current working on a design with very limit size. Thanks a lot! I don't know. You could...

@matthijskooijman You're right and I've already think about this but not so easy and will require some more study. As an example Mbed define PY_n_ALTx pin in the array to...

Here the `PeripheralPins.c` for a Nucleo F411RE: https://github.com/ARMmbed/mbed-os/blob/816689d1bbd5e82b64aa8af3cb294f6dac7130ec/targets/TARGET_STM/TARGET_STM32F4/TARGET_STM32F411xE/TARGET_NUCLEO_F411RE/PeripheralPins.c#L120

> One related improvement I just realized: Currently, every transaction calls `spi_init()` to configure the settings (e.g. clock speed). However, this also completely sets up the SPI device, including scanning...
