single wire half duplex mode, master/slave mode, data transceiver.
Master:SPI1_SCK(PA5)\SPI1_MOSI(PA7).
Slave:SPI1_SCK(PA5)\SPI1_MISO(PA6).
This routine demonstrates that Master sends and Slave receives.
Note: The two boards download the Master and Slave programs respectively,
and power on at the same time.
Hardware connection:PA5 -- PA5
