Detailed Description

Data transfers functions. 

 ===============================================================================
                    ##### Data transfers functions #####
 ===============================================================================  
    [..] This section provides a set of functions allowing to manage the SPI or I2S 
         data transfers.
    [..] In reception, data are received and then stored into an internal Rx buffer while 
         In transmission, data are first stored into an internal Tx buffer before being 
         transmitted.
    [..] The read access of the SPI_DR register can be done using the SPI_I2S_ReceiveData()
         function and returns the Rx buffered value. Whereas a write access to the SPI_DR 
         can be done using SPI_I2S_SendData() function and stores the written data into 
         Tx buffer.

Function Documentation

uint16_t SPI_I2S_ReceiveData16 ( SPI_TypeDef *  SPIx )

Returns the most recent received data by the SPIx peripheral.

Parameters:
SPIx,:To select the SPIx/I2Sx peripheral, where x can be: 1, 2, 3 or 4 in SPI mode or 2 or 3 in I2S mode or I2Sxext for I2S full duplex mode.
Return values:
Thevalue of the received data.
