&par Example Description

This example provides a description of how to set a communication between the two
SPIs in simplex mode and performs a transfer from SPI_MASTER in polling mode to the
SPI_SLAVE in DMA receive mode. A dedicated DMA channel is configured for SPI_SLAVE
Rx request to store received data in SPI_SLAVE_Buffer_Rx. If SPI data for transmiting is true,
the LED3 will be on.If the program is running normally, LED2 will blink.

Connection:
     PA4(SPI1_NSS)    --------    PB12(SPI2_NSS)      
     PA5(SPI1_SCK)    ---------   PB13(SPI2_SCK)
     PA6(SPI1_MISO)  --------    PB14(SPI2_MISO)
     PA7(SPI1_MOSI)  --------    PB15(SPI2_MOSI)
