Quick, how do you wire up an SPI bus between a microcontroller and a peripheral? SCK goes to SCK, MISO goes to MISO, and MOSI goes to MOSI, right? Yeah. You’ll need to throw in a chip select pin, but ...

The Zephyr SPI functions are slightly harder to use then than their Arduino counterparts, but they are also more sophisticated. The SPI driver is easy to acquire at compile time: static const struct ...
