SPI Driver
|
|
**********
|
|
|
|
The Serial Peripheral Interface (SPI) bus drivers should use the
|
|
`SPI bus framework
|
|
<https://git.rtems.org/rtems/tree/cpukit/dev/include/dev/spi/spi.h>`_.
|
|
For
|
|
example drivers see the
|
|
`Atmel SAM SPI driver <https://git.rtems.org/rtems/tree/bsps/arm/atsam/spi/atsam_spi_bus.c>`_
|
|
and the
|
|
`SPI framework test <https://git.rtems.org/rtems/tree/testsuites/libtests/spi01/init.c>`_.
|
|
|
|
The user API is compatible to the
|
|
`Linux SPI user-space API <https://www.kernel.org/doc/Documentation/spi/spidev>`_.
