TS-TPC-7990 CPU SPI Controller

SPI is located on the #DIO Header through /dev/spidev1.2.

This board includes one SPI interface which is accessible through either kernel drivers, or userspace using the /dev/spi interface.

The kernel development which would be needed to use other kernel space SPI drivers is beyond the scope of this document, but the build environment is described in the kernel compile guide here.

The /dev/spidev1.2 interface can be accessed using the userspace API. For more information see the documentation and sample code:

• Linux kernel spidev documentation
• spidev example code
