7-bit addressing mode, master/slave mode, transceiver routine:
I2C1_SCL(PB8)\I2C1_SDA(PB9).
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:PB8 -- PB8
PB9 -- PB9
