说明： stm32通过spi口与74hc595相连，然后由74hc595控制8盏灯的闪灭，注意该工程所用外接高速晶振为12MHZ,而大部分板子为8M赫兹，使用时需要修改锁相环倍频系数。
(stm32 through spi port is connected with 74hc595 and eight lights are ocontrolled by the 74hc595 , note that works with an external high-speed oscillator is 12MHZ, and most of the board of 8M Hz, you need to modify the PLL multiplication factor.)

@par Example Description
This example provides a description of how to set a communication between two
SPIs in full-duplex mode and performs a transfer from Master to Slave and
Slave to Master followed by CRC transmission.
SPI1 is configured as master and SPI2 as slave and both are in full-duplex
configuration mode with 16bit data size and a 4.5 Mbit/s communication speed
(for Value line devices the speed is set at 1.5 Mbit/s).
CRC calculation is enabled for both SPIs.
After enabling both SPIs, the first data from SPI2_Buffer_Tx is transmitted from
slave followed by the first data from SPI1_Buffer_Tx send by the master. A test
on RxNE flag is done for both master and slave to check the reception of data on
their respective data register. The same procedure is done for the remaining data
to transfer except the last ones.
Last data from SPI1_Buffer_Tx is transmitted followed by enabling CRC transmission
for SPI1 and the last data from SPI2_Buffer_Tx is transmitted followed by enabling
CRC transmission for SPI2: user must take care to reduce code on this phase for
high speed communication.
Last transmitted buffer data and CRC value are then received successively on
master and slave data registers. The received CRC value are stored on CRC1Value
and CRC2Value respectively for SPI1 and SPI2.
Once the transfer is completed a comparison is done and TransferStatus1 and
TransferStatus2 gives the data transfer status for each data transfer direction
where it is PASSED if transmitted and received data are the same otherwise it
is FAILED.
A check of CRC error flag, for the master and the salve, is done after receiving
CRC data.

evaluation boards and can be easily tailored to any other supported
device and development board.
This example can't be tested with STMicroelectronics STM3210C-EVAL (STM32F10x
Connectivity Line) evaluation board.
