This demo is based on the GD32307C-EVAL-V1.1 board, it shows the I2C programming
mode in master transmitting mode.In this demo,I2C0 is operated as the master
transmitter, and the SCL line and SDA line of I2C0 interface are controled by
the I/O pin PB6 and PB7 respectively.

This demo shows the sending process of the master. And it will send the data
in the i2c_transmitter array through I2C0.

The 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.
