* Description:
|
||||
* The external functions, lpc17_ssp0/ssp1select and lpc17_ssp0/ssp1status
|
||||
* 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 LPC17xx logic. To use this common SPI logic on your
|
||||
* board:
|
||||
*
|
||||
* 1. Provide logic in lpc17_boardinitialize() to configure SPI/SSP chip select
|
||||
* pins.
|
||||
* 2. Provide lpc17_ssp0/ssp1select() and lpc17_ssp0/ssp1status() 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).
