|

* board:
|

* These external functions must be provided by board-specific logic. They
|

* are implementations of the select, status, and cmddata methods of the SPI

* interface defined by struct spi_ops_s (see include/nuttx/spi.h). All

* logic. To use this common SPI logic on your board:
|
||||
*
|
||||
* 1. Provide logic in sam3u_boardinitialize() to configure SPI chip select
|
||||
* pins.
|
||||
* 2. Provide sam3u_spi1/2/3select() and sam3u_spi1/2/3status() functions in your
|
||||
* board-specific logic. These functions will perform chip selection and
|
||||
* status operations using GPIOs in the way your board is configured.
|
||||
* 3. Add a calls to up_spiinitialize() in your low level application
|
||||
* 2. Provide sam3u_spiselect() and sam3u_spistatus() functions in your
|
||||
* board-specific logic. These functions will perform chip selection
|
||||
* and status operations using GPIOs in the way your board is configured.
|
||||
* 2. If CONFIG_SPI_CMDDATA is defined in the NuttX configuration, provide
|
||||
* sam3u_spicmddata() functions in your board-specific logic. This
|
||||
* function will perform cmd/data selection operations using GPIOs in
|
||||
* the way your board is configured.
|
||||
* 3. Add a call to up_spiinitialize() in your low level application
|
||||
* initialization logic
|
||||
* 4. The handle returned by up_spiinitialize() may then be used to bind the
|
||||
* SPI driver to higher level logic (e.g., calling
|
||||
* SPI driver to higher level logic (e.g., calling
|

* mmcsd_spislotinitialize(), for example, will bind the SPI driver to
