SPI Driver
|
|
**********
|
|
|
|
The Serial Peripheral Interface (SPI) bus drivers should use the
|
|
`SPI bus framework
|
|
<https://git.rtems.org/rtems/tree/cpukit/include/dev/spi/spi.h>`_.
|
|
The user API is compatible to the
|
|
`Linux SPI user-space API <https://www.kernel.org/doc/Documentation/spi/spidev>`_.
|
|
|
|
For example SPI bus drivers see:
|
|
|
|
* `Atmel SAM SPI driver <https://git.rtems.org/rtems/tree/bsps/arm/atsam/spi/atsam_spi_bus.c>`_
|
|
* `NXP i.MX SPI driver <https://git.rtems.org/rtems/tree/bsps/arm/imx/spi/imx-ecspi.c>`_
|
|
* `NXP LPC17XX/LPC24XX/LPC40XX SSP driver <https://git.rtems.org/rtems/tree/bsps/arm/lpc24xx/spi/ssp.c>`_
|
|
* `SPI framework test <https://git.rtems.org/rtems/tree/testsuites/libtests/spi01/init.c>`_
