* Name: stm32_spi1/2/...select and stm32_spi1/2/...status
|
|
*
|
|
* Description:
|
|
* The external functions, stm32_spi1/2/...select, stm32_spi1/2/...status, and
|
|
* stm32_spi1/2/...cmddata 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/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/...select() and stm32_spi1/2/...status() 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 file, then
|
|
* provide stm32_spi1/2/...cmddata() functions in your board-specific logic.
|
|
* These functions will perform cmd/data selection operations using GPIOs in the
|
|
* way your board is configured.
|
|
* 4. Add a calls 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).
