CC3200 SDK SPI问题

注意CC3200有三个SPI接口：

(1)SSPI-片外SPI_Flash

(2)GSPI-通用SPI

(3)LSPI-连接片内NWP接口

 driverlib\spi.c    ---> GSPI

 middleware\driver\spi_drv.c

 simplelink\cc_pal.c

 simplelink\cc_pal_pm.c

NOTE:

The driverlib/spi.c files are the core APIs that are used to communicate using the SPI interface.

All other implementations (in simplelink and middleware) are higher level APIs that would inturn invoke the driverlib APIs. You could use any of them as reference/invoke them for your development.

Further, only the GSPI can be used by the application.

The other 2 SPI modules cannot be used by the application and has the following role:

FlashSPI is used to communicate with the SFLASH.

LSPI is used for communication by the application processor with the network processor.

SSPI 是给外部的SPI Flash 的驱动

GSPI Used by application processor
