  This demo is based on the GD32W515P-EVAL-V1.0, it shows the I2C programming 
mode in slave receiving mode. In this demo, I2C1 is operated as slave receiver, 
and the SCL line and SDA line of I2C1 interface are controlled by the I/O pin 
PB15 and PA8 respectively.

  This demo shows the receiving process of the slave. And it will store the 
received data in the i2c_receiver array.

  The demo doesn't perform the data transfer actually, which is due to no specific 
master.In the specific application, we need configure the master to start a data 
transmission. In addition,the master and the slave may need to be connected by 
the jumper if necessary.
