*@Note
CRC error check and master/slave mode transceiver routine:
Master:SPI1_SCK(PA5)\SPI1_MOSI(PA7).
Slave:SPI1_SCK(PA5)\SPI1_MISO(PA6).
This example demonstrates the use of CRC error checking, the Master sends and
the Slave receives.
Note: The two boards download the Master and Slave programs respectively, and
power on at the same time.
Hardware connection:PA5--PA5
PA7--PA6
