* Description:
|
||||
* The external functions, stm32_spi1/2/3select and stm32_spi1/2/3status must be
|

* provided by board-specific logic. They are implementations of the select
|

* and status methods of the SPI interface defined by struct spi_ops_s (see

||||
* include/nuttx/spi/spi.h). All other methods (including up_spiinitialize())
|
||||
* 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 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).
