|

* The external functions, lm3s_spiselect, lm3s_spistatus, and
|
||||
* lm3s_spicmddata must be provided by board-specific logic. These 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
|
||||
* logic. To use this common SPI logic on your board:
|
||||
*
|
||||
* 1. Provide logic in lm3s_boardinitialize() to configure SPI chip select
|
||||
* pins.
|
||||
* 2. Provide lm3s_spiselect() and lm3s_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.
|
||||
* 3. If CONFIG_SPI_CMDDATA is defined in your NuttX configuration, provide
|
||||
* the lm3s_spicmddata() function in your board-specific logic. This
|
||||
* functions will perform cmd/data selection operations using GPIOs in
|
||||
* the way your board is configured.
|
||||
* 4. Add a call to up_spiinitialize() in your low level application
|
||||
* initialization logic
|
||||
* 5. 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).
