*@Note
PEC error check, master/slave mode transceiver routine:
I2C1_SCL(PB8)\I2C1_SDA(PB9).
This example demonstrates that the Master sends with PEC error checking, and the
Slave receives. If a transmission error occurs, an error interrupt is triggered.
Note: The two boards download the Master and Slave programs respectively,
and power on at the same time.
Hardware connection:PB8 -- PB8
PB9 -- PB9
