[SOLVED] STM32 as SPI slave

[jgromes]

Hi,

Is there support for slave mode in the Arduino core? I can't seem to find anything relevant in the SPI library source.

Thanks!

There is no dedicated API for this.
You can try to use HAL/LL for this.

Which result of that incredibly helpful Google search is even remotely related to my question? I'm asking precisely because I couldn't find anything, neither in the repository issues nor in the library code.

Thanks, I ended up having to use DMA for my project, but I'll see if I can add simple interrupt-driven support for SPI slave mode - would a PR for this be accepted?

While this not breaks Arduino API and generic for all series, why not.
