SPI is located on the DIO header and is available in software via /dev/spidev1.2
This platform includes one SPI interface which is accessible through either kernel drivers or userspace using the /dev/spi interface.
Developing or implementing kernel SPI drivers are beyond the scope of this document, but the build environment is described in the kernel compile guide.
The /dev/spidev1.2 interface can be accessed using the userspace API. For more information see the documentation and sample code:
