To prevent data corruption when using multiple SPI devices on the same bus, care must be taken to ensure that they are only accessed from within the main loop, or from the interrupt routine, never ...

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 ...

Notice that we have set the pin to active low to make sure that CS is low when the SPI device is selected. Now we can configure the SPI port: struct spi_config config; struct spi_cs_control cs_ctrl = ...
