I2C Slave

[luke_par]

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

Hi,

which core you used?
viewtopic.php?f=2&t=301

I guess this issue was opened by you: https://github.com/rogerclarkmelbourne/ ... /issues/97
So I guess you use LibMaple ?

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.

You don't really answer the question.
Anyway as you used an L412, I guess you used the STM32 core.
Then in the Wire example you will find what you are looking for.

But Wire is only used for I2C?

Sorry, SPI but your topics is I2C slave ...

Sorry, was a mistake on my part

How can I change it?
