* Name: kinetis_spi/ssp0/ssp1select, kinetis_spi/ssp0/ssp1status, and

* kinetis_spi/ssp0/ssp1cmddata
|
||||
*
|
||||
* Description:
|
||||
* 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 other methods
|
||||
* including up_spiinitialize()) are provided by common Kinetis logic. To use
|
||||
* this common SPI logic on your board:
|
||||
*
|
||||
* 1. Provide logic in kinetis_boardinitialize() to configure SPI/SSP chip select
|
||||
* pins.
|
||||
* 2. Provide kinetis_spi/ssp0/ssp1select() and kinetis_spi/ssp0/ssp1status() 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
|
||||
* kinetis_spi/ssp0/ssp1cmddata() functions in your board-specific logic. These
|
||||
* functions 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
|
||||
* mmcsd_spislotinitialize(), for example, will bind the SPI driver to
|
||||
* the SPI MMC/SD driver).
