DlnSpiMasterReadWrite() Function




  The DlnSpiMasterReadWrite() function sends and receives data via SPI bus. The data are received as an array of 1-byte
  elements. This function is suited to transmit data frames of 8 bits or less. In case you set a frame size of more than
  8 bits, it is advised to use the
  DlnSpiMasterReadWrite16() function.




Parameters:



  
handle

  

    A handle to the DLN-series adapter.
  

  
port

  

    A number of the SPI master port.
  

  
size

  

    The size of the message buffer. This parameter is specified in bytes. The maximum value is 256 bytes.
  

  
writeBuffer

  

    A pointer to an array of unsigned 8-bit integers. This array must be filled with data to be sent to a slave during
    the function execution.
  

  
readBuffer

  

    A pointer to an array of unsigned 8-bit integers. This array will be filled with data received from slave during the
    function execution.
  




This function is defined in the dln_spi_master.h file.
