RE: Setting up SPIS with Interrupts using Zephyr

Hi Kenneth,

this helped a lot. I discovered that in the config the system needs "CONFIG_SPI_ASYNC=y" for it to also run asynchronously. I also implemented a semaphore to handle the controlling of the system in the place of directly using the ISR for the SPI.

Hello,

Normally I refer to the zephyr test examples for a specific driver, for instance I can that the following use CONFIG_SPI_SLAVE=y (also have an board overlay for the nRF52840):
\nrf\tests\benchmarks\spi_endless\
\zephyr\tests\drivers\spi\spi_controller_peripheral\
\zephyr\tests\drivers\spi\spi_error_cases\

I can also find a colleague shared a code example here while debugging an issue:
https://devzone.nordicsemi.com/f/nordic-q-a/110541/spis-buffer-cannot-receive-more-than-64-bytes/480602

Also find an example here:

Hope that helps as example,
Kenneth
