The question about the SPI in the KM34

小勇邹 — Thu, 19 Oct 2017 08:46:52 GMT

The device is used as SPI slave.

I want to receive the SPI1 data by interrupt method and send the SPI1 data by the DMA method.

Is it possible to do it?

Hi Robin zou,

Yes, you can do it like that.

Please check the DMA request sources at first:

You can find the receive and send SPI is the different request ID, so you can use send as DMA, receive as interrupt.

Wish it helps you!
Have a great day,
Kerry
