* Description:
|

* The external functions, stm32_spi1/2/3select and stm32_spi1/2/3status

* must be provided by board-specific logic. They are implementations of

* spi_ops_s (see include/nuttx/spi/spi.h). All other methods
|
||||
* (including stm32_spibus_initialize()) are provided by common STM32 logic.
|
||||
* To use this common SPI logic on your board:
|
||||
*
|
||||
* 1. Provide logic in stm32_boardinitialize() to configure SPI chip select
|
||||
* pins.
|
||||
* 2. Provide stm32_spi1/2/3select() and stm32_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 stm32_spibus_initialize() in your low level
|
||||
* application initialization logic
|
||||
* 4. The handle returned by stm32_spibus_initialize() 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).
