/* SPI bus defining tools
|
|
* For new boards we use a board_config.h to define all the SPI functionality
|
|
* A board provides SPI bus definitions and a set of buses that should be
|
|
* enumerated as well as chip selects that will be interatorable
|
|
*
|
|
* We will use these in macros place of the uint32_t enumeration to select a
|
|
* specific SPI device on given SPI1 bus.
|
|
*
|
|
* These macros will define BUS:DEV For clarity and indexing
|
|
*
|
|
* The board config then defines:
|
|
* 1) PX4_SPI_BUS_xxx Ids -the buses as a 1 based PX4_SPI_BUS_xxx as n+1 aping to SPI n
|
|
* where n is {1-highest SPI supported by SoC}
|
|
* 2) PX4_SPIDEV_yyyy handles - PX4_SPIDEV_xxxxx handles using the macros below.
|
|
* 3) PX4_xxxx_BUS_CS_GPIO - a set of chip selects that are indexed by the handles. and of set to 0 are
|
|
* ignored.
|
|
* 4) PX4_xxxx_BUS_FIRST_CS and PX4_xxxxx_BUS_LAST_CS as PX4_SPIDEV_lll for the first CS and
|
|
* PX4_SPIDEV_hhhh as the last CS
|
|
*
|

|

*
