Arduino for STM32

How can I change it?

Sorry, was a mistake on my part

But Wire is only used for I2C?

Thanks for your quick response.

Yes I opened the issue but closed it again immediately, because I noticed that it is in the wrong area.

I use a ST Nucleo L412KB with a STM32L412KBU6U.

Hello,
I would like to use an STM32 as SPI slave, which sends data to an SPI master on request of the master. Unfortunately all Arduino examples are Atmega specific. Does anyone have a source code example for me?

Thanks
