* The external functions, pic32mx_spi2select and pic32mx_spi2status
|

* 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.h). All other methods (including up_spiinitialize())
|

* are provided by common PIC32MX logic. To use this common SPI logic on your
|
||||
* board:
|
||||
*
|
||||
* 1. Provide logic in pic32mx_boardinitialize() to configure SPI/SPI chip select
|
||||
* pins.
|
||||
* 2. Provide pic32mx_spi2select() and pic32mx_spi2status() 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).
