  This demo is based on the GD32F30x-EVAL board, it shows the I2C programming mode in master 
transmitter mode and slave receiving mode. In this demo,I2C0 is operated as master transmitter
,I2C1 is operated as slave receiver and the SCL line and SDA line of I2C interface are controled 
by the I/O pin PB10 and PB11(or PB6 and PB7) respectively.

  This demo shows the sending data process of the master and the receiving data process of the slave.
If transfer is sucessfully completed, LED1 and LED2 is light.
