    How to use SPI of  CYW20735

    mawu_4270096

      Hi:

       

        as  we know, the  spi  master initial API  is below:

       

       

      void wiced_hal_pspi_init(  spi_interface_t spi,

                                 UINT8           devRole,

                                 UINT16          spiPinPullConfig,

                                 UINT32          spiGpioCfg,

                                 UINT32          clkSpeed,

                                 SPI_ENDIAN      endian,

                                 SPI_SS_POLARITY polarity,

                                 SPI_MODE        mode,

                                 UINT8           csPin);

       

      there is a  input parameter(UINT8           csPin)of the wiced_hal_pspi_init, can  I  use the IO pin that does  not  belong  to the CYW20735  to control  the  SPI slave cs?

       

      if  I use  the   IO pin of  another  MCU  as  the  CS  PIN ,  how to  fill  in  the  input  parameter   UINT8  csPin   of  the   wiced_hal_pspi_init  API

       

       

      thanks!
