本例展示了如何实现2个SPI之间的在全双工（full-duplex）模式下通信，通过NSS软件管理，实现了由主向从，接着又从向主发送数据。
在本例程中，设置SPI1和SPI2为8bit数据帧，9Mbit/s传输速率。
在第一阶段，由主SPI1把SPI1_Buffer_Tx发送到SPI2，由从SPI2把SPI2_Buffer_Tx发送到SPI1。传输完成后，通过比较判断传输是否正确。
由于NSS管脚由软件管理，因此，可以在不改变硬件配置的情况下使SPI1由主变从，而SPI2由从变主。在第二阶段，由从SPI1把SPI1_Buffer_Tx发送到SPI2，由主SPI2把SPI2_Buffer_Tx发送到SPI1。传输完成后，通过比较判断传输是否正确。
在STM3210B-LK1上，如果以上4个传输都正确，则亮起LED1（LD4），否则亮起LED2（LD3）。,err
