This demo is based on the GD32W515P-EVAL-V1.0 board, it shows the I2C programming
mode in master receiving mode. In this demo, I2C1 is operated as master 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 data process of the master. And it will store
the received data in the i2c_receiver array.
This demo doesn't perform the data transfer actually, which is due to no
specific slave.In the specific application, we must send the correct slave
address, and the master and the slave may need to be connected by the jumper
if necessary. When the macro I2C_10BIT_ADDRESS is 1, I2C communicate in 10 bit
addressing mode, otherwise, I2C communicate in 7 bit addressing mode.
